The gold standard for understanding GTIL inverters and how it all functions. Took me a LOT of researching my own DIY setup…wish this video was available back then. What an asset for people to learn from, great video. Bravo!
I've been using the 2kw GTIL for a year in the US. No problems. Fantastic device. I've taken to calling it my little buddy as it works away pushing watts into the house. One of these days I will make a video on the specifics.
How do you prevent any potential back feeding during a power outage situation? I'm interested in doing something like this, but only if I can safely prevent it from going back on the grid.
@@OhDannyBoy2k yep, it's a grid tied inverter it needs the heartbeat of the grid. For safety reasons they all have to turn off immediately if the grid goes down. It's called anti-islanding.
The idea of this limiter used in this Grid tied inverter belongs to Rogel Naval a Filipino Engineer based in Manila. He had this made with masspower in China. It's called Grid Tied Inverter with Limiter or as we know it as GTIL. It's first version has an external limiter which is now phased out, what you see here is the version 2 that has an internal limiter. I had both versions and the version 2 with 22v-60v runs on 48v LiFePO4 batteries. Simple to use. Greetings from the Philippines 🇵🇭🇵🇭🇵🇭
I Had 2 of those already, work as described , easy to use and very versatile. The only problem is the excess heat when used above 1.5KW with the Battery voltage around 50v, mine have both burned out. If you plan to use more than 1.5kw in a sustain way, better to have a much higher battery voltage to reduce the DC input Amps .
This is a great suggestion. Limit the amps so that never producing over 1500w and for the 1kw limit the amps so the inverter won’t produce over 750w. I use a 60v nominal lithium battery to power both of my 2kw inverters. Voltage goes up to 64v. This is a good voltage to run the 45-90v inverters if using batteries. 48v battery is really to low to use with the 45-90v inverter. That low of voltage will make the inverter use more amps which isn’t good for it. For the 22-65v version a 48v battery is great
@@RJ-cc1fz I see you have got useful information here. I am concerned about the build quality in those inverters. In my opinion Chinese products are like, if they say 2000W for example you can assume it to be more like a 1000W device. So, you are saying if I was to build a system with the 2000W version for battery use, the battery pack voltage should be closer to the 90V DC range.
@@repairman2be250No it doesn't need to be that high. The max input amps is 35ah with 85% efficiency. So you need a 65v battery to get the full 2kw. So a 20s lifepo4 would be perfect here.
Great video Andy! It’s a genius device. Simple and seamless. I have not tried it myself (I’m completely off grid), but after seeing this video I started to think it might have a place in an off grid system after all…. My main problem with consumption is the “buffer” of maximum power I need to have. The bigger the inverter, the bigger the idle consumption. So I have a small inverter that I use for the easy loads, and a big, all-in-one that I only turn on when I’m to use microwave, washing machine, air compressor, etc. The difference in idle consumption between the two is around 25w, which doesn’t sound much, but since it’s 24/7, it makes a huge difference. The idle consumption of the device you test seems to be extremely low. So my idea here is that I might go even lower, just using a 300w-something inverter as a waveformer and use this device as a “dynamic buffer”. Do you think it would work?
Have you figured it out? Id like to be able to disconnect from the grid and "trick" an inverter like this somehow (preferably not with a generator) in a shtf situation. It seems you'd want a pure sine wave inverter to feed into it for it to get a clean signal.
If there is such a thing as a small inverter that you can set an output limit on and keep it from overloading then you would be golden but Im not sure if there is such an inverter. Would suck to overload your small inverter and the whole thing go down. It seems like redundancy is the only way to accomplish some things with solar, at least in a grid tied situation. It's unfortunate at the moment...
Bought 1 one year ago, now i have 3, each for one phase. Using it with solar to charge battery and this inverters connected to the 14s Li-ion battery. They work really nice. I recently added wind turbine aswell ;)
Thanks for sharing. I'm interested in a wind turbine setup myself. Not that we have super high winds here but from the general perspective and how it would integrate.
I used three phase bridge rectifier connected directly to the inverters(since they already have the capacitors to do the smoothing) and for brake i used arduino to check for high voltage and set pwm signal to do the braking on ssr relay connected to the heat brake depended on the high voltage. But so i don't discharge battery i used one diode in bettwen so it actuall brake the turbine and not drain battery. I coul use the controller that came with the turbine but i read that they fail on high winds (which i do have sometimes).
@@OffGridGarageAustralia the newer turbine don't need much wind like a 9blade one. It might not be windy on the ground but you put your wind meter or turbine up about 40ft and it's alot stronger then ground level. A turbine works better when the solar weather is poor e.g. wet windy stormy teribble for solar but great for wind, wind blows 24/7 so the decrease in performance can be made up with increased run time.
@@DanielSan-ch7dr We have like 130ft trees around us so I can see how the wind situation is, direction and strength. I might try it at some stage, but it's a lot of effort to put up the mast, make it all secure... we will see...
I greatly admire that even with people saying "oh that's a bad idea I wouldn't do that ect" too many people in this world think they know exactly what your situation is and exactly what you should do when the fact of the matter is they don't. I may not build things the way you or others do but by watching you go through your own trials, I learn a GREAT deal from it. NO ONE knows everything
... and I have tested these units now rather than installing them right away to see if it would work from a technical perspective. It would be a viable solution to my problem. And I wanted to share this here. Thanks for your feedback.
@@OffGridGarageAustralia Your videos have convinced me to give them a try. I'm still researching how to use this on the US split phase. I see people have wired two CT sensors in series (or is that parallel) with a small resistor. Too bad this is not offered from SUN. Wonder if you ever used these and do you still recommend them? Your videos are immensely helpful.
Glad you are using the Ecoworthy/SUN/GTIL inverters. No need for wire extensions. It is just 2 wires for the current sensor that run 0 to 5V. Just cut and add wire as needed. You can also adjust the sensitivity of the current sensor, I added a 2k trimpot that makes the inverter think I am using less watts than I really am. I don't think the inverter responds fast enough when a load is stopped so it backfeeds a little without tweaking with the trimpot.
@@benkanobe7500What do you need a schematic for? It's 2 wires. Cut the wire and split in a longer length. The resistor isn't necessary but you just put it on one wire.
Wow this is awesome, you know you have to show us how too stack them. Because 2 kilos isn’t enough. Please and give us more. There are no other videos as good as this one on the grid ties. Great job from Boncarbo Colorado.
very grateful for the great video I use this inverter here in my country where it is forbidden to export energy to the grid I learned a lot from your video to get the most out of the equipment's performance long live Australia! God blesses.
This video provides product information with value to those of us who don’t feel the need to step out of the shower to pee. I thoroughly enjoyed your demonstration. If I had a home I’d definitely purchase one of those inverters to offset my power costs. Thanks Andy!
I am very concerned about the build quality in terms of the power rating. Many chinese products don't live up to the specs. Der Kanal has had some in for repair with and without success in fixing them.
Thank you sir for this explanation of the sun2000. I have being looking for someone to teach me for months and the way you lay it out is so easy to understand and precise. Cheers
Hay Andy, I have some information for you... I have two inverters SUN2000gtil in last two years. If You develop your project about this inverter.. you will doing big mistake. I will explain why.. 1. This inverter is declared 2000 W but is not... Today this inverter product only 1200 W depending on environment temperature. I must set limitation of production to 1300 W. If is setting for limitation of production 1800 W ,then inverter is overheated and automatically limit power. On the end go to turn off. 2. One inverter was burned on and not have any option for repair it. I was buy second and on this inverter burned two small fet transistors for controlling fans. In this situation I was repair it. 3. This inverter have price 300 to 400 EUR (depending on the action). Two inverters in total 2500 W cost about 600 to 800 EUR-a. I think.. that is to much. 4. Inverter have very poor interface for monitoring. Addition problem with interface is.. when doin connection and read data, inverter stop working to one to two seconds. Real data is not real... this data is average in 5 minutes. 5. Warranty basically not exist.. 6. If you use battery, must buy two addition MPPT. Ok.. you have chargers but this price must be included in total price. I tings... more better option is buy inverter with all in one... Inverter with two mppt-a, Warranty 5-10 years and good interface to managing and monitoring. For example: Groowatt SPH series or GoodWee residential inverters. Both inverters have option for zero export which is controlled with smart meter or CT clamp. Inverters have connection to battery BMS an can configure point work for battery. SUN2000Gtil is good budget inverter for starting with solar experiences, but is not good for your project. I have plan to replace this inverters with Growatt SPH 3600 for which price is about 1350 EUR. With regards. P.S. Sorry for my English ..
Noe need to be sorry for your English at all. I agree with you not on the basis that I have actual facts, but on the basis Chinese product specs are in my opinion just half the values they advertise. So, a 2000W device is only good for about a 1000W. Forget about warranty, it might cost you more to ship back to China.
Thank you very much for this video it pretty much showed me everything about this inverter and this is exactly what I need, a big thank you from the Dominican Republic
Thanks again Andy! Mine SUN 2000 is just a few steps way from us - just got an alert that it’s just landed in Auckland - it might take couple of days (or weeks? hopefully not) to Christchurch - rewatching your video for the settings to be prepared. Thank you! Will try to buy you few SPAT’s ;)
20:43 European here. Wait a second.. in Europe sometimes we also use the current limiter included in the box of this exact inverter. In Europe, by law, we can output to the grid (with this type of plug-and-play inverters) a maximum of 800w (in some countries is overruled at 600w), and exactly because of this we use the current limiter, it makes us able to have bigger systems without breaking the law.
That is good info. Too bad that setup does not work for us in the US for the 2000 watt model. We need to monitor both legs of the split phase with the current limiters.
I have one of these connected to 1500w of solar panels and 4800 amp hours of batteries. It runs the house and charges the batteries during the day and draws off the batteries to run the house all night.
It gives me great pleasure to watch your videos with simple and to-the-point explanations. It would have been wonderful if this inverter had an input from the batteries and could set the automatic switch at a given time from the solar panels to the battery, thus ensuring operation at night or on very cloudy days. Thanks again for this interesting video material.
You don't need any switch. Just add a charge controller from your solar panels to your batteries and connect the inverter directly to your batteries. This way your solar will charge your batteries and the grid tie will run off batteries day and night or until your batteries get too low. If it does shut down at night due to low batteries it will come back on the next day automatically as soon as your batteries get to your reboot voltage.
Here in the U.S. I found that my limiter sensor was showing minus on the screen because the prior home owner had incorrectly wired the electrical receptacle (power point). They had wired the neutral to the hot side and the hot line to the neutral side. Appliances will work with such incorrect wiring, but there is a risk of an electrical shock. So, I rewired the receptacle and the minus went away.
Thanks Andy, very well done info session. I currently have a garrage that only has body corporate lighting installed. This sounds like the perfect solution (with a few panels on the roof) to have a daylight power source without the fear of inflating the body corporate electricity bill. You are a bloody legend!
I just buy by 160usd SoyoSource GTN-1200LIM48 1200W 48VBat with max 900W output, where limiter is per ModBus RS485 and we can have one CTclamp or Shelly3M meter and use reading for many of inwerters via wifi ESP modules. Best for ZeroExport / Auto-Consumption for ppl who cannot export any of Watts to grid. Cheap but perfect solution !
Still waiting to set mine up, just need to get some batteries to setup a 48v pack. Got 1kw of solar and 48v victron controller, my home base load is about 200w, got a few servers running. So it should work well without having to run the current sensor.
these inverters are brilliant, i have loads of them, some over 10 years old and still working flawlessly. that Wanpak power supply though, you really need to re cycle that into something usfull, they really are rubbish i have not seen one yet that has lasted longer than about 6 months 🙂
Great! But please reduce the idle consumption of your house. You could turn of your electronic devices instead of leaving them in standby. There are multiple outlet with switches that allow to do it conveniently for several devices at a time
Some reviews on Amazon about this backfeeding even with the limiters in place. Most utilities now days that have a smart meter will be alerted to this backfeeding. One review he says it was back feeding during a power outage a utility worker noticed power still on the grid after they cut the power going to the feed lines. Here in the US when you grid tie you required to have insurance in case of injury from back feeding to the grid while they are repairing it. Not sure how often that happens. I would imagine it is very rare.
Hi Andy, do you know if the limit sensor is bidirectional? As I have two systems and only want the battery one to produce power when the other one (non battery) stops feeding the grid.
Question, what grid of power is the power supply that you use comes from, is it the same grid that you use to power ON the lightings that you are testing?
cool video, after 2 years this unit stopped working, we have check the DC fuses, , all good, AC legs are both good. in put but the unit died, do we need to replace all teh mosfets?
@Off-Grid Garage sorry for the question but I am still learning. 1) is it good practise to plug the AC into a plug socket? I don't want to wire it into my main board as I don't want to touch anything there because I will be moving soon and I want to take the system with me. Is there some way I could maybe wire it to it's own breaker and from there to a plug socket, or is this still dangerous? 2) if I'm running panels to a battery and battery to the inverter then I would have to buy a separate MPPT controller to put on the other side of the battery? There would be no way for it to control it? This is only for panels connected directly? Thank you
This is the best explanation of how these work on UA-cam. Thank You. I have a question: If using batteries (I assume for after sunset) with only a maximum of 1000 Watts of daytime solar, would the inverter be able to recharge the batteries if they ran all night supplying 1000 Watts to the house and still be able to provide power to the house during the day or would it need to be dedicated to just recharging batteries. I am a little confused on that part.
This inverter does not have a charger. It's not a hybrid inverter. It's grid tied with power support. So it will deliver the energy used by your load as long as possible until the set low voltage cut-off is reached. The grid will then deliver the energy again until the voltage in your battery rises and the SUN takes over again.
@@OffGridGarageAustralia I am doing a bad job explaining so thank you for continuing to answer my dumb questions. If I want to take advantage of my large battery bank (AGM) at night, do I connect my panels to an appropriate charge controller that is then connected to my battery bank that is continuously connected my inverter? I would set the inverter to cut off at 37.30 or so VDC to be conservative to my batteries and then the inverter would restart in the morning when solar made voltage climb to set level?? I think you see how I want to use the inverter. Am I doing it correctly if as described above?
@@benkanobe7500 no dumb questions here at all. How you describe it here, that's exactly as it should be, The inverter should turn off at a set voltage to prevent the battery from being discharged further while the BMS does not trigger in this case and still acts like a safety switch to protect the battery if something goes wrong. Perfect setup.
@@OffGridGarageAustralia I'm a bit confused. As this has a MPPT solar controller, if you have a battery bank that you want to use with this, you would not be able to use the MPPT solar controller from this inverter?? Would the set up be - Solar Panels to Solar Controller to Battery Bank then from Battery bank back to Inverter ?
Absolutely beautiful, bought one off your link so hopefully you got a beer out of it. Just connected 48V Lead Acid battery bank and the sensor (incredible bit of tech) and plugged it in and Wow free elec running round the house. Can you do a 2 inverter to 1 live line Vid as I need more power man. Just waiting for the sun to shine in the UK (may take a while :)
Great informative video,thank you. I don’t get the constant nitpicking by the know all keyboard warriors? You are here to inform so the so called adults can make a judgement for THEMSELVES as to whether they should buy the product or not. It really is that simple guys. Fyi i have just installed a 3.2kw solar array with 2 SOK server rack batteries and i have just bought a 1.4kw micro inverter to feed directly into my ring main grid. After watching this video i realise should of bought one these grid tie inverters instead 🤦🏻♂️ they seem more user friendly. But hey we’re all still learning about this stuff. Thanks again
Thanks great video, have a question. I am in the UK where the Neutral is bonded to earth. If I add mcb and rcb between the inverter and my house mains, will the rcb work? Will there be any problems with grounding?
Hi there Thank you for the great video! 🙂 I do have a question that i hope you can help me out with. 😬 In your video at minute 12:13 through 12:25 , it shows that you have 53v comming in the inverter but your watt production is at 0.0w. You say it is on stand by. 🧐 How do you get out of stand by? 🤔 I am asking you cause, i use 2 of the same inverters but for wind turbine and even though i feed them with 53v or even 58v (depends on the wind) both inverters are never producing any power! I am getting really disappointed in the whole system. 😕 I thank you, in advance, for your time and answer.
@@OffGridGarageAustralia hi again and thank you for the quick reply. 👍🏻🙂 When the limiter option is on i get those 50 or 50+ volts in the inverter. When the limiter is off then the inverter brakes the wind turbine to a flat 20-22 volt. Both options ends up in no power production. 😕
No, they are not bonded in this inverter. That would be fatal. The MEN link is in your meter panel or distribution panel. It is only inside an inverter if it is an off-grid inverter.
Awesome video. I bought last year a SUN-1000 G2-H with two panel (I have the same version you had, 7.1). Last week I added a Pylontech US2000 battery and I configured the inverter with "battery or solar Power Mode" to 800W and configured a cut-off at 46V and reboot at 49V. The battery have a Dishcharge Volt at 44.5 ~ 53.5. In your opinion is the right configuration?
Hi! If I install the limiter sensor, I should also turn on the internal limiter in the menu to make it work properly? Or just leave the internal limiter off in the menu? My electricity provider does allow me to export electricity. I'm ordering one just like that in 1000 watts in either 22-60VDC or 45-90VDC depending on how many 100 watt panels and in what combination of series or parallel connection . Thank you for sharing and posting and these vids are plenty helpful to my project.
Excellent video and TNX also, I use the same in my grid tie setup with limiter since I have to pay if sending power into the grid, I produce a sine wave with a small generator in case power goes out and the gtil will kick in again and produce sun energy for my use as necessary.
30:50: " it is not a off grid inverter" Thia inverter can most likely used in a off-grid settings, with the sensor. The sensor makes shure there is no need production, and thereby supporting the inverter. I saw a video where someone had tried connecting a grid tied inverter in parallel to a off-grid inverter. It worked well, until the usage was below the production of the grid tied inverter. The over voltage destroy the off grid inverter. But here that clamp will most likely prevent that outcome.
Very good video. Thank you. I plan to sell power to grid from my battery when the price are high, (when I know I have that extra power) Your video made me feel confident to buy one. 👍🏻
nice, I have a wind turbine hooked up to mine and I am a bit reluctant to use the limiter cos I dont know what happens to any excess power produced. I assume it goes into the dump load (no batteries) but if it doesnt could it unload the turbine? which would be very bad.
Yes, although the one that came with it is 10 ohms and the one recommended by the turbine manufacturer is 4 ohms which I do not have. Any idea who to contact about the inverter as it has a blue internal light flashing about once a second I have another in which the light is steady and assume a fault of some kind but can't find the manufacturers to ask.
I have this inverter . At the beginning on the screen when its in red letters start up volt to low. You skip that step and I can not figure out how you got rid of that? Do I need the power controller to turn up and down our power as I do not have that controller. Do you have a video on the step I can not seem to get passed?
Hello and thank you for your great video .... but what happen if grid go down i wonder if there any way to keep invertet running even when grid is down
Ideally this would run on its own circuit solely for the reason that you could overload the circuit where things are connected to commended limited 20 A you could draw 30 amp is that inverted antenna into the circuit as well and that could make problems
Thanks for your feedback. The GTI2 and the micro inverter are two different things. The GTI has the major advantage of having this export limiter, So depends on your situation and system design which one to choose.
I like this grid tied with limiter inverter idea; i just wonder how dependable the limiter is. Who might have headaches of charging your grid by mistake, on a smart meter set up, and then experiencing consequences from the Grid Electricity Supplier ??? That is my main concern to this otherwise good idea.
The remote number is for the rs485 identity. If you change it the wifi dongle Will not work. I am trying to control the export with a raspberry pi. However I do not have a clamp do you know what the voltage or preferably waveform looks like. Also if you press and hold the top 2 buttons on power on you get the firmware menu. Thanks for clarifying the reboot voltage now I know why it only kicks back in at 27 volts. Mine is just for controlling a wind turbine. Thanks in advance.
Hi Andy! big hello from italy! just an ask, what if i'll give the grid to another bigger inverter (with no limiter functions) from this with limiter (i mean to connect the AC output of the sun gtil2 to the AC input of another inverter)? the surplus energy of the main inverter go back to the gtil2 and what will happen? shoud be a trick for have limiter function to an inverter that don't have it?
Hi Ross and hello to Italy. That is a bad idea unless the 2nd inverter is a Victron Multiplus II or Quattro which can handle AC input from another inverter.
hi Andy, because of you i am building a 28kw 48v battery and i want to be able to sell back my power in the summer, and this inverter makes a lot off sense to make this happen. BUT will this inverter stop sending power in the grid when the grid go down? so like workers cut the cable. because no power can flow when the grid is down to protect the workers and the grid. do you know if this inverter does this? thanks
Great video. Would connecting a backup generator to the house when the power is off cause any problems for this inverter or would it just work as normal?
Dear friend.Thank you for the scientific approach and explanation for this 2 Kw On grid inverter with limiter.Because in my country right now we have a small heat wave with inside temperatures 32oC. I wonder how can i cool up my 3 x 2KW inverters. A. Should i place a timer so from 11 mid day up to 14.00 to have a break and actually cut the input power of the inverter???do i need to cut only the input power or do i need also to cut with a rele the solar voltage that feeds the inverter???? B.Shoula i place a 7000 btu aircon??? from a wheelhouse that i have???Whats your opinion please.Thank you Very much.
The have a power limit . I would like the inverter to regulate the input dc voltage not the power . With this mode you could set up maximum and minimum dc voltage and the inverter would regulate the dc input to keep the voltage inside the user defined limits . Can this be done ?
Hey Andy, thanx for realy great videos. You have made many of my days :-) Just one question regarding SUN 2000 or 1000. Normally at the manual SUN is prohibiting to connect two invertors on one PV string. Understood. But teoretically connect two inverters on one battery bank should works. Am I right? or not. Thank you for respond or help.
Thank you Jozef. Yes, that is correct. You can connect as many of these inverters to one battery as you like and parallel them to increase output power.
Andy I appreciated your beaviour. It well done aproach. Fast easy clear answer. Sorry but next question. I have went through of your videos and looking for right answer about the most suitable BMS for EVE bat cell for example. I have seen your hard execsising with Daly. JK and QUCC xiaoxiang better but I could not find right answer which one is most suitable for. Would be great to get your opinion for the most suitable BMS with EVE or others bat cells. Thx and keep fire burning. Go ahead as till now or even better
If i were to use this inverter along side a solar array already would it produce 0 watts if the existing inverter is feeding power back to the grid and the ct clamp reads negative numbers? A family member gets paid a generous generation tariff for their current system but doesnt have battery storage (old inverter) they are wanting to use a system like this to cover load at night but not feedback to the grid from this system during the day. Any feedback from users would be much appreciated
good solution👍. you might think about a manual or automatic transfer switch for when the grid goes down. at the point the grid goes down the txfer switch txfers to the off grid inverter "generator" and when the power comes back on it txfers back to city power. it shouldn't effect the new inverters.
If you cut off your grid connection as anti-islanding protection, will you need to add another earth for use when you are not on the grid? I get confused about earth types and I am not sure what earth is provided in Australia but it looks as though Andy gets an earth from his supplier.
Good and clear explanation of the feature settings for SUN Grid Tie invertor. I have two 1KW model over here in the US and has watched many videos on UA-cam but no one has gone through each setting as clearly as you had. Will do you a video on hooking up WiFi-Port Plug Wifi Modem for SUN-1000GTIL2 SUN-2000GTIL2?
Great video. What would happen if you don't connect the current sensor? Would it always produce the maximum power available from the panels? Would it know what the house is producing and export the rest? also What do you think about using this inverter in parallel with another on grid inverter of different brand? without any rs485 communication between them. For example if there was an on grid inverter at the house with 2-3kwp panels connected to the grid close to the power meter and then 20 m away at the garage we instal this GTIL inverter with 1kwp panels and connect it to the junction box of the garage but without running the current sensor 20m all the way near the power meter. Would they work together to produce whatever is needed to power the house and garage and export the rest or would they just trip each other out?
I've just had solar installed and they have connected the inverter direct to the grid side of my smart meter so i have to pay for all the energy I use. I asked why and they said that if the inverter was connected to the house mains and I used more than it was producing it would cut out.
Thanks for the overview. There is similar model for 3-phase wind power generators. Do you think it can be used with solar instead (at the end of the day the 3-phase AC input is converted to DC inside the box).
I don't think it is convert to DC actually, these are grid tie inverters which don't charge a battery. The inverter for wind power cannot be used for solar, no.
Love your video very informative on how this all works. I'm based in the UK and currently have 2 inverters a growatt String inverter and a growatt hybrid inverter without batteries at the moment which are connected to the grid. Would like to know if this would work with what I currently have setup and to be used as a wind turbine rather than solar as I've seen this used with wind.
We have the 2000 watt version however it stopped working do they have an internal fuse it says lifetime warranty what's the page on Amazon disappeared thank you in advance
Sorry, hit enter too soon. Somewhere along the way watching your videos, I misplaced the link to the resistors you used to precharge the capacitors so there is not a larger spark. Possible to post that link or send me to the right place.
I have 4 of these same types of types of tigrids and verters but nowhere can I find on how much amps can run through these machines we know how much voltage can run but how much amps can you put through these machines I want to know if I can take a 48 voteight 8 vote battery called Reynold rhino from big batteries Which has 276 AH Is that too much amp hours or is this OK I can't find in the destructions or any UA-cam videos to tell the capability on how much amperage can run through these machines
Depends on which model you have. There should be a label on the side with the information you need. The one I tested went from 40-90V input voltage from the solar or battery side. The higher the output, the more amps it pulls from the battery.
Dear Sir, I have a small question related to this 2000W SUN GTIL2 inverter. My solarpanels are CanadianSolar with each 455 Wp and these specifications: PMax: 455W; Imp: 11.02A; Vmp:41.3V; Voc: 49.3V; Isc: 11.66A Since the input voltage should be between 45-90V and in your video it shows that it "kicked in" at a little more than 50V I don't know how to connect the panels to the inverter. How many panels can I connect and how many parallel, how many in series?
@@OffGridGarageAustralia Thank you sir. That's too bad, because it looks such a nice inverter and you explained it so well. Next time when I add some panels I make sure they are not so big and I can use this inverter. Thanks again. I also subscribed to your channel, because you have many interesting videos :).
Thanks for your video and information! Do you have any recommendation about a similar inverter but for just 120v with the same function and limiter? I can't use 220V. Sorry.
Here's a trick Put two Coil taps one on each side in USA cut wires put them in Series! Now it will read both legs instead on one! Now we just have to figure out how to make these last longer then a year or two.
Could you please tell me if this would work with a 600 w windmill and a 100w solar panel.? Edit not how well or what to expect ... Just would this work
Can these 2000w models be used in US? I thought several videos had mentioned only the 1000w/120ac models work in the states? For the 2k models do you need 2 sensors? one for each 120 branch of the 240 grid power input to your homes panel?
The gold standard for understanding GTIL inverters and how it all functions. Took me a LOT of researching my own DIY setup…wish this video was available back then. What an asset for people to learn from, great video. Bravo!
I have the same 2kw inverter. He make a very good Job for now 2 years. He produze 3560kwh without any Problems. Thats amasing. I love these inverter.
I've been using the 2kw GTIL for a year in the US. No problems. Fantastic device. I've taken to calling it my little buddy as it works away pushing watts into the house. One of these days I will make a video on the specifics.
You've got the YT channel, so go for it.
How do you prevent any potential back feeding during a power outage situation? I'm interested in doing something like this, but only if I can safely prevent it from going back on the grid.
I think I've answered my own question - if the grid goes down, so does this system.
Would love to see more details on how you rigged this.
@@OhDannyBoy2k yep, it's a grid tied inverter it needs the heartbeat of the grid. For safety reasons they all have to turn off immediately if the grid goes down. It's called anti-islanding.
The idea of this limiter used in this Grid tied inverter belongs to Rogel Naval a Filipino Engineer based in Manila. He had this made with masspower in China. It's called Grid Tied Inverter with Limiter or as we know it as GTIL. It's first version has an external limiter which is now phased out, what you see here is the version 2 that has an internal limiter. I had both versions and the version 2 with 22v-60v runs on 48v LiFePO4 batteries. Simple to use. Greetings from the Philippines 🇵🇭🇵🇭🇵🇭
Thanks a lot for sharing, Ian. That is great info!
I Had 2 of those already, work as described , easy to use and very versatile. The only problem is the excess heat when used above 1.5KW with the Battery voltage around 50v, mine have both burned out. If you plan to use more than 1.5kw in a sustain way, better to have a much higher battery voltage to reduce the DC input Amps .
This is a great suggestion. Limit the amps so that never producing over 1500w and for the 1kw limit the amps so the inverter won’t produce over 750w. I use a 60v nominal lithium battery to power both of my 2kw inverters. Voltage goes up to 64v. This is a good voltage to run the 45-90v inverters if using batteries. 48v battery is really to low to use with the 45-90v inverter. That low of voltage will make the inverter use more amps which isn’t good for it. For the 22-65v version a 48v battery is great
@@RJ-cc1fz I see you have got useful information here. I am concerned about the build quality in those inverters. In my opinion Chinese products are like, if they say 2000W for example you can assume it to be more like a 1000W device. So, you are saying if I was to build a system with the 2000W version for battery use, the battery pack voltage should be closer to the 90V DC range.
@@repairman2be250No it doesn't need to be that high. The max input amps is 35ah with 85% efficiency. So you need a 65v battery to get the full 2kw. So a 20s lifepo4 would be perfect here.
Great video Andy! It’s a genius device. Simple and seamless. I have not tried it myself (I’m completely off grid), but after seeing this video I started to think it might have a place in an off grid system after all….
My main problem with consumption is the “buffer” of maximum power I need to have. The bigger the inverter, the bigger the idle consumption. So I have a small inverter that I use for the easy loads, and a big, all-in-one that I only turn on when I’m to use microwave, washing machine, air compressor, etc. The difference in idle consumption between the two is around 25w, which doesn’t sound much, but since it’s 24/7, it makes a huge difference.
The idle consumption of the device you test seems to be extremely low.
So my idea here is that I might go even lower, just using a 300w-something inverter as a waveformer and use this device as a “dynamic buffer”. Do you think it would work?
Have you figured it out? Id like to be able to disconnect from the grid and "trick" an inverter like this somehow (preferably not with a generator) in a shtf situation. It seems you'd want a pure sine wave inverter to feed into it for it to get a clean signal.
@@lancealderman2755 No, I was hoping that Andy would test it since he had the device, but seems he sent it back for some reason 🤷🏼♂️
If there is such a thing as a small inverter that you can set an output limit on and keep it from overloading then you would be golden but Im not sure if there is such an inverter. Would suck to overload your small inverter and the whole thing go down.
It seems like redundancy is the only way to accomplish some things with solar, at least in a grid tied situation. It's unfortunate at the moment...
@@lancealderman2755 If the sun2000 is quick enough providing power, that scenario should not surface. That is what I would have liked Andy to test….
Oh you want to feed the Sun 2000 with a battery bank?
Great inverter, I have one too. For off-grid you can use the Victron to fool the GTIL2 into thinking there is grid power.
Bought 1 one year ago, now i have 3, each for one phase. Using it with solar to charge battery and this inverters connected to the 14s Li-ion battery. They work really nice. I recently added wind turbine aswell ;)
Thanks for sharing. I'm interested in a wind turbine setup myself. Not that we have super high winds here but from the general perspective and how it would integrate.
I used three phase bridge rectifier connected directly to the inverters(since they already have the capacitors to do the smoothing) and for brake i used arduino to check for high voltage and set pwm signal to do the braking on ssr relay connected to the heat brake depended on the high voltage. But so i don't discharge battery i used one diode in bettwen so it actuall brake the turbine and not drain battery. I coul use the controller that came with the turbine but i read that they fail on high winds (which i do have sometimes).
@@OffGridGarageAustralia the newer turbine don't need much wind like a 9blade one. It might not be windy on the ground but you put your wind meter or turbine up about 40ft and it's alot stronger then ground level.
A turbine works better when the solar weather is poor e.g. wet windy stormy teribble for solar but great for wind, wind blows 24/7 so the decrease in performance can be made up with increased run time.
@@DanielSan-ch7dr We have like 130ft trees around us so I can see how the wind situation is, direction and strength. I might try it at some stage, but it's a lot of effort to put up the mast, make it all secure... we will see...
I greatly admire that even with people saying "oh that's a bad idea I wouldn't do that ect" too many people in this world think they know exactly what your situation is and exactly what you should do when the fact of the matter is they don't. I may not build things the way you or others do but by watching you go through your own trials, I learn a GREAT deal from it. NO ONE knows everything
... and I have tested these units now rather than installing them right away to see if it would work from a technical perspective. It would be a viable solution to my problem. And I wanted to share this here.
Thanks for your feedback.
@@OffGridGarageAustralia Your videos have convinced me to give them a try. I'm still researching how to use this on the US split phase. I see people have wired two CT sensors in series (or is that parallel) with a small resistor. Too bad this is not offered from SUN. Wonder if you ever used these and do you still recommend them? Your videos are immensely helpful.
Glad you are using the Ecoworthy/SUN/GTIL inverters. No need for wire extensions. It is just 2 wires for the current sensor that run 0 to 5V. Just cut and add wire as needed. You can also adjust the sensitivity of the current sensor, I added a 2k trimpot that makes the inverter think I am using less watts than I really am. I don't think the inverter responds fast enough when a load is stopped so it backfeeds a little without tweaking with the trimpot.
Ah, right, I was wondering about this. They say you can extend up to 20m only though.
Could you show a schematic or links for us non-technical people? This sounds like an excellent idea!
@@benkanobe7500What do you need a schematic for? It's 2 wires. Cut the wire and split in a longer length. The resistor isn't necessary but you just put it on one wire.
@@shawnd567 Hey thanks. I feel stupid now. Great job!
Wow this is awesome, you know you have to show us how too stack them. Because 2 kilos isn’t enough. Please and give us more. There are no other videos as good as this one on the grid ties. Great job from Boncarbo Colorado.
very grateful for the great video I use this inverter here in my country where it is forbidden to export energy to the grid I learned a lot from your video to get the most out of the equipment's performance
long live Australia!
God blesses.
Glad it helped. Thank you.
This video provides product information with value to those of us who don’t feel the need to step out of the shower to pee. I thoroughly enjoyed your demonstration. If I had a home I’d definitely purchase one of those inverters to offset my power costs. Thanks Andy!
I've just purchased the 2000w with limiter for use in my shed, here in England. Fantastic info, thank you..
I am very concerned about the build quality in terms of the power rating. Many chinese products don't live up to the specs. Der Kanal has had some in for repair with and without success in fixing them.
Stuart mate, I've just bought some panels and so now looking into grid tie inverter, do you use just solar? Or do you use batteries aswell?
I have 2 of these inverters connected in parallel and I think you have the best video for explaining the device 👏
Thank you sir for this explanation of the sun2000. I have being looking for someone to teach me for months and the way you lay it out is so easy to understand and precise.
Cheers
app for smartphone?
Hay Andy,
I have some information for you...
I have two inverters SUN2000gtil in last two years. If You develop your project about this inverter.. you will doing big mistake. I will explain why..
1. This inverter is declared 2000 W but is not... Today this inverter product only 1200 W depending on environment temperature. I must set limitation of production to 1300 W.
If is setting for limitation of production 1800 W ,then inverter is overheated and automatically limit power. On the end go to turn off.
2. One inverter was burned on and not have any option for repair it. I was buy second and on this inverter burned two small fet transistors for controlling fans. In this situation I was repair it.
3. This inverter have price 300 to 400 EUR (depending on the action). Two inverters in total 2500 W cost about 600 to 800 EUR-a. I think.. that is to much.
4. Inverter have very poor interface for monitoring. Addition problem with interface is.. when doin connection and read data, inverter stop working to one to two seconds. Real data is not real... this data is average in 5 minutes.
5. Warranty basically not exist..
6. If you use battery, must buy two addition MPPT. Ok.. you have chargers but this price must be included in total price.
I tings... more better option is buy inverter with all in one... Inverter with two mppt-a, Warranty 5-10 years and good interface to managing and monitoring.
For example: Groowatt SPH series or GoodWee residential inverters.
Both inverters have option for zero export which is controlled with smart meter or CT clamp. Inverters have connection to battery BMS an can configure point work for battery.
SUN2000Gtil is good budget inverter for starting with solar experiences, but is not good for your project.
I have plan to replace this inverters with Growatt SPH 3600 for which price is about 1350 EUR.
With regards.
P.S. Sorry for my English ..
Noe need to be sorry for your English at all. I agree with you not on the basis that I have actual facts, but on the basis Chinese product specs are in my opinion just half the values they advertise. So, a 2000W device is only good for about a 1000W. Forget about warranty, it might cost you more to ship back to China.
Thank you very much for this video it pretty much showed me everything about this inverter and this is exactly what I need, a big thank you from the Dominican Republic
Great video, The print in the booklet was so small that it is hard to read. You saved me a lot of frustration'
Thanks again Andy! Mine SUN 2000 is just a few steps way from us - just got an alert that it’s just landed in Auckland - it might take couple of days (or weeks? hopefully not) to Christchurch - rewatching your video for the settings to be prepared. Thank you! Will try to buy you few SPAT’s ;)
Is it possible to simulate a grid power by using a pure sinewave DC/AC converter/charger for this grid-tie inverter ?
I was wondering that myself, no needed wasting sunshine or batteries during a grid outage 😊
Excellent, thank you for spending the time to do such a thorough job of explaining this product
20:43 European here. Wait a second.. in Europe sometimes we also use the current limiter included in the box of this exact inverter. In Europe, by law, we can output to the grid (with this type of plug-and-play inverters) a maximum of 800w (in some countries is overruled at 600w), and exactly because of this we use the current limiter, it makes us able to have bigger systems without breaking the law.
That is good info. Too bad that setup does not work for us in the US for the 2000 watt model. We need to monitor both legs of the split phase with the current limiters.
Öttinger Bier ich schmeiss mich voll weg!!! Jetzt hab ich all deine Videos durch. Respekt!
I have one of these connected to 1500w of solar panels and 4800 amp hours of batteries. It runs the house and charges the batteries during the day and draws off the batteries to run the house all night.
It gives me great pleasure to watch your videos with simple and to-the-point explanations. It would have been wonderful if this inverter had an input from the batteries and could set the automatic switch at a given time from the solar panels to the battery, thus ensuring operation at night or on very cloudy days. Thanks again for this interesting video material.
You don't need any switch. Just add a charge controller from your solar panels to your batteries and connect the inverter directly to your batteries. This way your solar will charge your batteries and the grid tie will run off batteries day and night or until your batteries get too low. If it does shut down at night due to low batteries it will come back on the next day automatically as soon as your batteries get to your reboot voltage.
Technical Term for the outlets is "GPO" = General Purpose Outlet. the term "Power Point" is a Microsoft program
Yes.
thank you for review . bought SUN GTIL2 and i'm very happy, works very well
Here in the U.S. I found that my limiter sensor was showing minus on the screen because the prior home owner had incorrectly wired the electrical receptacle (power point). They had wired the neutral to the hot side and the hot line to the neutral side. Appliances will work with such incorrect wiring, but there is a risk of an electrical shock. So, I rewired the receptacle and the minus went away.
I had to watch this a few times, regardless of how simple you made, oh wow has this given me what I needed
Thanks Andy, very well done info session. I currently have a garrage that only has body corporate lighting installed. This sounds like the perfect solution (with a few panels on the roof) to have a daylight power source without the fear of inflating the body corporate electricity bill. You are a bloody legend!
I just buy by 160usd SoyoSource GTN-1200LIM48 1200W 48VBat with max 900W output, where limiter is per ModBus RS485 and we can have one CTclamp or Shelly3M meter and use reading for many of inwerters via wifi ESP modules. Best for ZeroExport / Auto-Consumption for ppl who cannot export any of Watts to grid. Cheap but perfect solution !
Vidéo d'explication très pédagogique, merci Andy !
Question sir : is there any low wattagge limiter, in 18:55 you show an upper limit., but theres no lower limit..
Still waiting to set mine up, just need to get some batteries to setup a 48v pack.
Got 1kw of solar and 48v victron controller, my home base load is about 200w, got a few servers running.
So it should work well without having to run the current sensor.
these inverters are brilliant, i have loads of them, some over 10 years old and still working flawlessly. that Wanpak power supply though, you really need to re cycle that into something usfull, they really are rubbish i have not seen one yet that has lasted longer than about 6 months 🙂
I have repaired my Wanptek twice. Both was my own fault though because of reverse connection at higher voltage.
Great! But please reduce the idle consumption of your house. You could turn of your electronic devices instead of leaving them in standby. There are multiple outlet with switches that allow to do it conveniently for several devices at a time
Your reaction at 4:30 made me laugh so hard everyone in the office turned around! Lucky I’m watching this in my lunch break…
He always seems so happy when speaking English, brightens my day up, awesome guy there should be more like him in the world
very good explained, thumbs up but too much advertisements ...
Sorry for that, it is totally up to Google to place that. It supports the channel though so...
Some reviews on Amazon about this backfeeding even with the limiters in place. Most utilities now days that have a smart meter will be alerted to this backfeeding. One review he says it was back feeding during a power outage a utility worker noticed power still on the grid after they cut the power going to the feed lines. Here in the US when you grid tie you required to have insurance in case of injury from back feeding to the grid while they are repairing it. Not sure how often that happens. I would imagine it is very rare.
Hi Andy, do you know if the limit sensor is bidirectional? As I have two systems and only want the battery one to produce power when the other one (non battery) stops feeding the grid.
very nice presentation , it made clear a lot of functions and installation details .
thank you .
Thanks.
Question, what grid of power is the power supply that you use comes from, is it the same grid that you use to power ON the lightings that you are testing?
cool video, after 2 years this unit stopped working, we have check the DC fuses, , all good, AC legs are both good. in put but the unit died, do we need to replace all teh mosfets?
@Off-Grid Garage sorry for the question but I am still learning.
1) is it good practise to plug the AC into a plug socket? I don't want to wire it into my main board as I don't want to touch anything there because I will be moving soon and I want to take the system with me. Is there some way I could maybe wire it to it's own breaker and from there to a plug socket, or is this still dangerous?
2) if I'm running panels to a battery and battery to the inverter then I would have to buy a separate MPPT controller to put on the other side of the battery? There would be no way for it to control it? This is only for panels connected directly?
Thank you
This is the best explanation of how these work on UA-cam. Thank You. I have a question: If using batteries (I assume for after sunset) with only a maximum of 1000 Watts of daytime solar, would the inverter be able to recharge the batteries if they ran all night supplying 1000 Watts to the house and still be able to provide power to the house during the day or would it need to be dedicated to just recharging batteries. I am a little confused on that part.
This inverter does not have a charger. It's not a hybrid inverter. It's grid tied with power support. So it will deliver the energy used by your load as long as possible until the set low voltage cut-off is reached. The grid will then deliver the energy again until the voltage in your battery rises and the SUN takes over again.
@@OffGridGarageAustralia I am doing a bad job explaining so thank you for continuing to answer my dumb questions. If I want to take advantage of my large battery bank (AGM) at night, do I connect my panels to an appropriate charge controller that is then connected to my battery bank that is continuously connected my inverter? I would set the inverter to cut off at 37.30 or so VDC to be conservative to my batteries and then the inverter would restart in the morning when solar made voltage climb to set level?? I think you see how I want to use the inverter. Am I doing it correctly if as described above?
@@benkanobe7500 no dumb questions here at all. How you describe it here, that's exactly as it should be, The inverter should turn off at a set voltage to prevent the battery from being discharged further while the BMS does not trigger in this case and still acts like a safety switch to protect the battery if something goes wrong. Perfect setup.
@@OffGridGarageAustralia I'm a bit confused. As this has a MPPT solar controller, if you have a battery bank that you want to use with this, you would not be able to use the MPPT solar controller from this inverter?? Would the set up be - Solar Panels to Solar Controller to Battery Bank then from Battery bank back to Inverter ?
Muito Bom!!!! Tenho um inversor grid tie limiter de 1000W com 2900Wp em paineis qual o valor maximo de potencia eu posso ligar neste equipamento
Ordered one the other day thanks for the video on this Andy nice to see it in action thank you sir
No problem 👍
Absolutely beautiful, bought one off your link so hopefully you got a beer out of it. Just connected 48V Lead Acid battery bank and the sensor (incredible bit of tech) and plugged it in and Wow free elec running round the house. Can you do a 2 inverter to 1 live line Vid as I need more power man. Just waiting for the sun to shine in the UK (may take a while :)
Great informative video,thank you.
I don’t get the constant nitpicking by the know all keyboard warriors?
You are here to inform so the so called adults can make a judgement for THEMSELVES as to whether they should buy the product or not.
It really is that simple guys.
Fyi i have just installed a 3.2kw solar array with 2 SOK server rack batteries and i have just bought a 1.4kw micro inverter to feed directly into my ring main grid.
After watching this video i realise should of bought one these grid tie inverters instead 🤦🏻♂️ they seem more user friendly.
But hey we’re all still learning about this stuff.
Thanks again
Thanks great video, have a question. I am in the UK where the Neutral is bonded to earth. If I add mcb and rcb between the inverter and my house mains, will the rcb work? Will there be any problems with grounding?
We have the same MEN link here in AU. Yes, RCD will work just fine, no problem at all. Consider using an MCBO (MCB and RCD combined).
Hi there
Thank you for the great video! 🙂
I do have a question that i hope you can help me out with. 😬
In your video at minute 12:13 through 12:25 , it shows that you have 53v comming in the inverter but your watt production is at 0.0w. You say it is on stand by. 🧐
How do you get out of stand by? 🤔
I am asking you cause, i use 2 of the same inverters but for wind turbine and even though i feed them with 53v or even 58v (depends on the wind) both inverters are never producing any power!
I am getting really disappointed in the whole system. 😕
I thank you, in advance, for your time and answer.
Do you use the limiter option? If not, you have to turn this off in the settings.
@@OffGridGarageAustralia hi again and thank you for the quick reply. 👍🏻🙂
When the limiter option is on i get those 50 or 50+ volts in the inverter.
When the limiter is off then the inverter brakes the wind turbine to a flat 20-22 volt.
Both options ends up in no power production. 😕
@@sevastianosprenta7471
Try to limit the power it is allowed to supply. You should be able to find a sweet spot where it works I would think.
Great video. Do you know if the neutral and ground are internally bounded in the inverter? Thank you
No, they are not bonded in this inverter. That would be fatal. The MEN link is in your meter panel or distribution panel. It is only inside an inverter if it is an off-grid inverter.
Awesome video. I bought last year a SUN-1000 G2-H with two panel (I have the same version you had, 7.1). Last week I added a Pylontech US2000 battery and I configured the inverter with "battery or solar Power Mode" to 800W and configured a cut-off at 46V and reboot at 49V. The battery have a Dishcharge Volt at 44.5 ~ 53.5. In your opinion is the right configuration?
Hi! If I install the limiter sensor, I should also turn on the internal limiter in the menu to make it work properly? Or just leave the internal limiter off in the menu? My electricity provider does allow me to export electricity. I'm ordering one just like that in 1000 watts in either 22-60VDC or 45-90VDC depending on how many 100 watt panels and in what combination of series or parallel connection . Thank you for sharing and posting and these vids are plenty helpful to my project.
You only need the limiter if you want to limit the power been exported or prevent a feed-in altogether. Otherwise both can be turned off.
Excellent video and TNX also, I use the same in my grid tie setup with limiter since I have to pay if sending power into the grid, I produce a sine wave with a small generator in case power goes out and the gtil will kick in again and produce sun energy for my use as necessary.
30:50: " it is not a off grid inverter"
Thia inverter can most likely used in a off-grid settings, with the sensor.
The sensor makes shure there is no need production, and thereby supporting the inverter.
I saw a video where someone had tried connecting a grid tied inverter in parallel to a off-grid inverter.
It worked well, until the usage was below the production of the grid tied inverter. The over voltage destroy the off grid inverter.
But here that clamp will most likely prevent that outcome.
Very good video. Thank you. I plan to sell power to grid from my battery when the price are high,
(when I know I have that extra power)
Your video made me feel confident to buy one. 👍🏻
Contemplating of having this at home. Thank you for a very informative video.
Thank you for your feedback and kind words.
nice, I have a wind turbine hooked up to mine and I am a bit reluctant to use the limiter cos I dont know what happens to any excess power produced. I assume it goes into the dump load (no batteries) but if it doesnt could it unload the turbine? which would be very bad.
The inverter for small wind turbines usually need this dump resistor connected. Does yours have this?
Yes, although the one that came with it is 10 ohms and the one recommended by the turbine manufacturer is 4 ohms which I do not have. Any idea who to contact about the inverter as it has a blue internal light flashing about once a second I have another in which the light is steady and assume a fault of some kind but can't find the manufacturers to ask.
I have this inverter . At the beginning on the screen when its in red letters start up volt to low. You skip that step and I can not figure out how you got rid of that? Do I need the power controller to turn up and down our power as I do not have that controller. Do you have a video on the step I can not seem to get passed?
Hello and thank you for your great video .... but what happen if grid go down i wonder if there any way to keep invertet running even when grid is down
Ideally this would run on its own circuit solely for the reason that you could overload the circuit where things are connected to commended limited 20 A you could draw 30 amp is that inverted antenna into the circuit as well and that could make problems
Gday Andy. Choose between the gti2 or your deye microinverter for ease of use and longevity? Great videos by the way
Thanks for your feedback.
The GTI2 and the micro inverter are two different things. The GTI has the major advantage of having this export limiter, So depends on your situation and system design which one to choose.
I like this grid tied with limiter inverter idea; i just wonder how dependable the limiter is. Who might have headaches of charging your grid by mistake, on a smart meter set up, and then experiencing consequences from the Grid Electricity Supplier ??? That is my main concern to this otherwise good idea.
The remote number is for the rs485 identity. If you change it the wifi dongle Will not work. I am trying to control the export with a raspberry pi. However I do not have a clamp do you know what the voltage or preferably waveform looks like. Also if you press and hold the top 2 buttons on power on you get the firmware menu. Thanks for clarifying the reboot voltage now I know why it only kicks back in at 27 volts. Mine is just for controlling a wind turbine. Thanks in advance.
Thanks Dave. I'm not sure about the CT's specs but you can buy them online for around $50.
Hi Andy! big hello from italy! just an ask, what if i'll give the grid to another bigger inverter (with no limiter functions) from this with limiter (i mean to connect the AC output of the sun gtil2 to the AC input of another inverter)? the surplus energy of the main inverter go back to the gtil2 and what will happen? shoud be a trick for have limiter function to an inverter that don't have it?
Hi Ross and hello to Italy.
That is a bad idea unless the 2nd inverter is a Victron Multiplus II or Quattro which can handle AC input from another inverter.
hi Andy, because of you i am building a 28kw 48v battery and i want to be able to sell back my power in the summer, and this inverter makes a lot off sense to make this happen. BUT will this inverter stop sending power in the grid when the grid go down? so like workers cut the cable. because no power can flow when the grid is down to protect the workers and the grid. do you know if this inverter does this?
thanks
Great video. Would connecting a backup generator to the house when the power is off cause any problems for this inverter or would it just work as normal?
If the inverter fails or is turned off, the power will come form the grid automatically. With such a system, there is no need for a gen.
Dear friend.Thank you for the scientific approach and explanation for this 2 Kw On grid inverter with limiter.Because in my country right now we have a small heat wave with inside temperatures 32oC. I wonder how can i cool up my 3 x 2KW inverters. A. Should i place a timer so from 11 mid day up to 14.00 to have a break and actually cut the input power of the inverter???do i need to cut only the input power or do i need also to cut with a rele the solar voltage that feeds the inverter???? B.Shoula i place a 7000 btu aircon??? from a wheelhouse that i have???Whats your opinion please.Thank you Very much.
The have a power limit . I would like the inverter to regulate the input dc voltage not the power . With this mode you could set up maximum and minimum dc voltage and the inverter would regulate the dc input to keep the voltage inside the user defined limits . Can this be done ?
Hey Andy, thanx for realy great videos. You have made many of my days :-)
Just one question regarding SUN 2000 or 1000. Normally at the manual SUN is prohibiting to connect two invertors on one PV string. Understood. But teoretically connect two inverters on one battery bank should works. Am I right? or not. Thank you for respond or help.
Thank you Jozef. Yes, that is correct. You can connect as many of these inverters to one battery as you like and parallel them to increase output power.
Andy I appreciated your beaviour. It well done aproach. Fast easy clear answer. Sorry but next question. I have went through of your videos and looking for right answer about the most suitable BMS for EVE bat cell for example. I have seen your hard execsising with Daly. JK and QUCC xiaoxiang better but I could not find right answer which one is most suitable for. Would be great to get your opinion for the most suitable BMS with EVE or others bat cells. Thx and keep fire burning. Go ahead as till now or even better
@@alets9788 thanks you for your comment and question. The best BMS so far is the JK-BMS for all batteries 8s and more.
If i were to use this inverter along side a solar array already would it produce 0 watts if the existing inverter is feeding power back to the grid and the ct clamp reads negative numbers? A family member gets paid a generous generation tariff for their current system but doesnt have battery storage (old inverter) they are wanting to use a system like this to cover load at night but not feedback to the grid from this system during the day. Any feedback from users would be much appreciated
good solution👍. you might think about a manual or automatic transfer switch for when the grid goes down. at the point the grid goes down the txfer switch txfers to the off grid inverter "generator" and when the power comes back on it txfers back to city power. it shouldn't effect the new inverters.
If you cut off your grid connection as anti-islanding protection, will you need to add another earth for use when you are not on the grid? I get confused about earth types and I am not sure what earth is provided in Australia but it looks as though Andy gets an earth from his supplier.
Nice, complete & long explanation.
Love your videos, I'm purchasing two of these. I wonder if this is the same as the marsrock and the Y&H inverters.
is this the new version of grid tie inverters that can accept battery inputs as well?
Good and clear explanation of the feature settings for SUN Grid Tie invertor. I have two 1KW model over here in the US and has watched many videos on UA-cam but no one has gone through each setting as clearly as you had. Will do you a video on hooking up WiFi-Port Plug Wifi Modem for SUN-1000GTIL2 SUN-2000GTIL2?
How is the unit workout ? Any problem? I am thinking about buying many units.
Great video. What would happen if you don't connect the current sensor? Would it always produce the maximum power available from the panels? Would it know what the house is producing and export the rest? also What do you think about using this inverter in parallel with another on grid inverter of different brand? without any rs485 communication between them. For example if there was an on grid inverter at the house with 2-3kwp panels connected to the grid close to the power meter and then 20 m away at the garage we instal this GTIL inverter with 1kwp panels and connect it to the junction box of the garage but without running the current sensor 20m all the way near the power meter. Would they work together to produce whatever is needed to power the house and garage and export the rest or would they just trip each other out?
Thanx ! Makes it better to understand with your video 😁👍🏻
I've just had solar installed and they have connected the inverter direct to the grid side of my smart meter so i have to pay for all the energy I use. I asked why and they said that if the inverter was connected to the house mains and I used more than it was producing it would cut out.
Thanks for the overview.
There is similar model for 3-phase wind power generators. Do you think it can be used with solar instead (at the end of the day the 3-phase AC input is converted to DC inside the box).
I don't think it is convert to DC actually, these are grid tie inverters which don't charge a battery.
The inverter for wind power cannot be used for solar, no.
hi there, I have 2kw 45-90v Wind grid always show voltage to low ,do you know what dam setting I should do? many thanks
What are you using for a WIFI connection?
I'm Interested in monitoring from my cell phone.
How to open the assembly (fac) settings which pops up after the first start? settings got saved badly?
Love your video very informative on how this all works.
I'm based in the UK and currently have 2 inverters a growatt String inverter and a growatt hybrid inverter without batteries at the moment which are connected to the grid.
Would like to know if this would work with what I currently have setup and to be used as a wind turbine rather than solar as I've seen this used with wind.
We have the 2000 watt version however it stopped working do they have an internal fuse it says lifetime warranty what's the page on Amazon disappeared thank you in advance
Thank you for the video! Great piece of kit. Do you know if it is possible to change the power limit remotely? Via ethernet or sth? Thabks!
Sorry, hit enter too soon. Somewhere along the way watching your videos, I misplaced the link to the resistors you used to precharge the capacitors so there is not a larger spark. Possible to post that link or send me to the right place.
still watching video and trying to like again 😄🤣 at least 3 times while watching but already liked so it wouldn't let me add another ❤
I have 4 of these same types of types of tigrids and verters but nowhere can I find on how much amps can run through these machines we know how much voltage can run but how much amps can you put through these machines I want to know if I can take a 48 voteight 8 vote battery called Reynold rhino from big batteries Which has 276 AH Is that too much amp hours or is this OK I can't find in the destructions or any UA-cam videos to tell the capability on how much amperage can run through these machines
Depends on which model you have. There should be a label on the side with the information you need. The one I tested went from 40-90V input voltage from the solar or battery side.
The higher the output, the more amps it pulls from the battery.
Dear Sir,
I have a small question related to this 2000W SUN GTIL2 inverter.
My solarpanels are CanadianSolar with each 455 Wp and these specifications:
PMax: 455W; Imp: 11.02A; Vmp:41.3V; Voc: 49.3V; Isc: 11.66A
Since the input voltage should be between 45-90V and in your video it shows that it "kicked in" at a little more than 50V I don't know how to connect the panels to the inverter. How many panels can I connect and how many parallel, how many in series?
The inverter can handle a max input voltage of 90V. So the panels you have are not suitable for this inverter.
@@OffGridGarageAustralia Thank you sir. That's too bad, because it looks such a nice inverter and you explained it so well. Next time when I add some panels I make sure they are not so big and I can use this inverter. Thanks again. I also subscribed to your channel, because you have many interesting videos :).
when you aren't using much power, does it make the power meter run backwards?
Thanks for your video and information! Do you have any recommendation about a similar inverter but for just 120v with the same function and limiter? I can't use 220V. Sorry.
It’s available on Amazon etc. just look for the 120V version.
Here's a trick Put two Coil taps one on each side in USA cut wires put them in Series! Now it will read both legs instead on one! Now we just have to figure out how to make these last longer then a year or two.
North American and South American mainly has 110/120VAC at the outlets. Not just the US
The black wire is the active one ? 😂 great information definitely would me on getting 1 or 2
Could you please tell me if this would work with a 600 w windmill and a 100w solar panel.?
Edit not how well or what to expect ... Just would this work
Can these 2000w models be used in US? I thought several videos had mentioned only the 1000w/120ac models work in the states?
For the 2k models do you need 2 sensors? one for each 120 branch of the 240 grid power input to your homes panel?
yes, it can. To answer your CT question, yes you do. I created a video of my setup to explain.
