I cannot thank you enough for posting these videos. I plan to install two of these units soon. I am also in the USA so the clamp advice is greatly appreciated.
Thank you for this video in details. I am copying your layout and will add batteries later on down the road too. Thanks again
Can I get the model number of the inverter u have? I saw this on Amazon:
ECO-WORTHY 1000W LCD Display MPPT Solar Grid Tie Inverter Power Limiter PV System DC 45-90V to AC90-140V
Not sure if it is the same one. But this one say :
THIS GRID TIE INVERTER CAN'T CONNECT WITH BATTERY BANK!!!
Also I only have access to 295watts panels. Is it ok to run 4 panels per unit (serial and parallel)? 1180watts
i used your configuration surge protection and box from china but not the disconnect box or the timer i order the Smart Plug 4 Pack Treatlife Smart WiFi Outlet Works with Alexa and Google Home, 2.4GHz WiFi Only, 7 Day Heavy Duty Programmable. and a cam when im at work and get a weather alert on phone i can cut the inverter off from work the cam has motion alert the rain hitting the panel sets it off get a live feed from the panels on the rack . good job on explaining your system . hats off
HOWdy J-G-O,

...
since you installed your solar how has it reduced your electric bill ? thanks
thankyou for your update video
I think we would all like to know total cost. Whats the ROI. Is it worth it- would you do it again? How many kW have you produced? Are you data logging? A video answering those questions would be awesome
hello Jim,
I like and appreciate your video, effort u put in your project. I myself have been so frustrated to utilize the 10 panels i purchased from recycle center where some customer/ commercial/ was not happy with it and give it to the recycle center where they resell it for 1/3 of price These panels are Boviet 375W / model BVM 6612M-375-H /.... that is how i got it. From that point it is just challenge to utilize them, mount them, wire them, and i am still in process....
First I bought 2000 grid tie with limiter from ebay. / it was specified in ebay seller as 120v out//// and it came with sticker for 185V-265V out. and it came without limiter... That they sent the limiter which was missing after week from china, but it did come...
after long back and for emails they specified how to connect it. so I did, it was working 2 days and then it died. now is in the mail for return.....sad... frustrating....
I called friend to help install the limiter... we installed it in the before enter to main circ. breaker.... alive... my question is , can that limiter be installed around the wire which is before the el. meter? / coming in my case from ground ????????
BTW, where in Ohio u are???/ just wonder
Thanks if u will read this....
I probably like idea for 2 pieces of 1000W inverters, and to put it to one for each leg....
I also was thinking to separate / figure out / which leg is powering what outlet in house and be able to control that somehow... like put my all refrigerators on one leg and maybe just feed only that leg with one controller.... Anyway, i do not want batteries, just simple system and help during the day...
Any word of advice???
Thanks for reading this

Hi. Sorry to hear about the problems you are experiencing. Regarding the 2000w inverter you have, there is a guy on UA-cam that shows how to connect those so they work well in the U.S. Do a search for SolarEngineering and check his videos. Regarding installation of the limiter, are you referring to the limiter clamp? Or an actual external limiter? I ask because I’m not aware of any of those without an internal limiter already built in. If you are referring to the clamp, the SolarEnginnering guy goes into detail for wiring two of those in series to work with the 2K unit. I hope that helps! Also, I am just outside of Columbus, Ohio. Take care!
@@jimginnyohio Thanks Jim ,
I was referring to the physical location of the clamp. Too bad, I can"t attach photo... and it was plagued to internal limiter side of the unit.
I am waiting for refund and then I will buy next unit and looks like to get 120V is challenge.. Yesterday I spent another day researching and
educated myself in this field.
I was not able to find the video you suggested , but thats ok, thanks again....Ivan
easy way to make power nice
Thank you for this great series of videos Jim. One question, can the wires to the load sensor clamp be extended? My panel is about 100' from where I will be installing the solar system.
I've heard of some people extending the clamp cable up to 25-35 feet. However, a 100-foot extension will probably cause issues resulting in an inaccurate reading. Best to try moving the inverter(s) closer to the power panel.
Loving these videos, there so precise and let you know EXACTLY whats watt, excuse the pun,can you please tell me ,if you know, how would you connect battery's to these panels and if you can, will thay feed back on a night time to your house, thank you for all your time spent ,kind regards Mark.
Thanks for the compliments! Yes, that can be done. Although I have not done that myself, I know that several others have done so and have posted videos about that. Check out "Old Time Engineer's" channel for that. ua-cam.com/video/LlHm0-inmlE/v-deo.html
He has several videos covering that topic. Also search for Grid Tied Inverter on Batteries. Just be sure to set it up in a way that your batteries are not completely drained since that can cause some damage. Happy hunting!
Sorry to bother you again. And thank you for such a fast response to the last post. I'm looking at purchasing 4 355 watts 48-volt panels. Two panels for each leg. My question is it better to wire 2 panels in series and get the hirer voltage Grid Tie inverter as you did, or wire 2 panels in parallel and get the lower voltage grid-tie inverter. Would running the panels in series be more efficient than running them in parallel.
Thank you again for such a great CLEAR and understandable video
Mike Balzer
You should configure them based upon whatever your inverter needs. At 48 volts per panel, you would be over the 90 volt maximum for the higher voltage inverter if you wired those in series. At the same time, you would be over the voltage for the lower voltage inverter too. If using 48 volt panels, you would need to get the higher voltage inverter and wire them in parallel if I am understanding you correctly.
Yes the closer to the output voltage the less work the panel has to do. :)
God bless!
Thank you for the update Jim! great job on everything. Do you know if you can add a battery pack to the sun grid tie inverter to be able to minimize grid use at night?
Yes, as long as the battery voltage matches the required voltage on the inverter you select. These 110V GTIs are available in either a 25-60V range or a 45-90V range. Your battery voltage must match the model you purchase. Within the menu of these, you will need to program the startup and shutoff voltage so that when your battery pack gets low, it shuts off. That can also be controlled if your battery has a BMS.
@@jimginnyohio thank you!
Thanks for the video, i am planning to use one of this thing with 2kw version. Ia there any setting to minimize the grid supply, and is it possible to extend the length of the limiter cable?
Hi - Not sure what you are asking "to minimize the grid supply". The inverter will automatically sense the amount of power being used by your home and will supply as much power as possible to offset that which is being supplied by the grid. If the inverter is producing more than you are using, then all of the power will be supplied by the inverter. However, if you are using more than the inverter is producing, your home will first use the inverter power and the rest of the power will be supplied by the grid. I hope that answers your question??
Yes, you can extend the length of the limiter cable since it is only two wires. However, I've heard reports that you should not extend it beyond 35-50 feet since the readings will not be accurate beyond that.
One other point of importance: If you are using the 2kw version within the US, you will need to get a limiter cable that has two clamp sensors on it since in the US, we have two 120v circuits coming into the house. You can get details for a dual clamp and how to connect that by reviewing the information in this Facebook Group: Solar Grid Tie Inverter with Limiter USA Users.
Good luck with your installation! Take care!
Jim this has been a very informative series and I thank you for it. I have a question about how you connected your second GTIL, since the 2 legs on the grid are 180 degrees out of phase with one another? Do these units somehow synchronize with the incoming grid? Please explain in layman terms. Thanks.
Rod Reeves Since these devices are grid tie inverters, they are able to synchronize with the grid independent of each other. Each device monitors and provides power to separate sides of the grid. Since they synchronize with the grid power, they aren’t aware of each other. Does that make sense?
@@jimginnyohio It does make sense that they would sychronize independently. I just have not seen any documentation that these particular devices have that capability. Thanks for the quick reply. Hope everything continues to go well.
Great video again and thanks. I see you set up the limit at 440 for your 1kW GTIL. I have the 2kW GTIL, do you recommend I set the setting at 440v?
czar revs Actually, you can disable those settings completely unless you have batteries connected to your inverter.
Hello, thks for your help. I have two 1000 watt inverters each has 1000 watts worth of panels connected to EACH separate inverter. One inverter and panels for L1 and exact duplicate setup for L2. Been running great for a year now. Question- anyway I can make more efficient though? For instance (just example)there are times L1 is pulling it's Max Watts and L2 may have nothing running so no load. Any easy way for the second inverter to be able to chip in and help out when there is excess draw on L1? I probably either have to somehow split the clamps so they see both legs or maybe master slave the inverters is there some easy way to do this that you know of?
Hi, love your videos! I was wondering how did you connect the SCT023R to the cable that connects to the GTI? How do you know what wires from SCT023R goes to pin 1 or pin 2 on the connector that plugs into GTI to get an accurate reading?
Simply cut off the old sensor and connect the two wires either way onto the SCT023R. It really doesn’t matter which wire goes to each of the pins. However, when you power up the inverter, check the lcd screen for the power reading. If the value is negative, flip the clamp sensor around the other way on the power leg cable coming into your breaker box. I hope that helps.
Hello Jim Thanks for the vides. Do you have a net meter? If not how do you stop from feeding the grid?
pete h No, I do not have a net meter. The inverter I am using has a built in limiter device. When that is enabled, it will sense the amount of power needed in the house and will limit the production to no more power than that being used. This way, no power is fed into the grid.
@@jimginnyohio thanks for the reply
Hello, thank you for your videos.😊 so,Can I have 2 inverters 1kva , and plug them to my grid plug?
Also, about the limiters, 2 inverters I have 2 limiters, is ok to add 2 limiters on my main wire so i dont exporting power back into the Grid? It will works? Thank you so much
Yes, you can do that, but you will need to insure you plug each device into opposite 120v legs of your circuit panel. The limiter clamps will also need to be on each of the main lugs for the leg the inverter is plugged into.
Thanks for the valuable videos! I live in the USA where there is single phase 240 volt power. As you know there are two 120 volt wires that connect separate circuits in the electrical panel. I want to buy two Inverters but I do not want a separate solar array for each inverter. Can I wire both inverters into the same solar array and then wire each inverter into each leg 120 of my electrical panel? Thanks!
Unfortunately, you would need to run separate positive and negative cables from your panels to each inverter since they are sensitive to over voltage and amperage. I had and array of 12 panels with three separate positive and negative cables running to my house. Four panels were used for one inverter, four for the other inverter, and four for my off-grid system.
@@jimginnyohio THANKS BERY MUCH!
i have the same unit, the total KWH and Today KWH in ENergy view is stuck at zero, i did a factory reset, i contacted sells MarsRock he only offered to by the wifi adapter from him. Any suggestions? Thank you so much
I purchased the SCT023R clamp as the other wouldn't fit around my line. Question= These clamps are big and very loose around the L1 wire, do these need to be snug or is loose ok for accurate readings? I cant seem to find any info on this.
Yes, that clamp will be accurate! It really doesn’t need to be tight at all as long as the wire goes thru it and it is closed completely, the clamp will successfully read the eddy current passing thru it. Good luck!
Hello, great video. I have a few questions I hope you can help me with. Sorry if I missed it. Do both circuits for the inverters each on one leg?
Meaning a leg has a feed and b leg has its own feed to the other inverter
Neil Cartwright Yes, that is correct. Each inverter and monitor clamp is on a different leg.
First off, thank you for making all these videos, they are extremely helpful and great! I just got one of these GTILs the other day and have a question. I see yours functions just like mine which is a little confusing. When using the limiter, your current sensor showed 50-60 watts being used but the inverter producing nearly 600 watts. How is that not back feeding the grid? This really confuses me. I have mine hooked up to a kill-a-watt and it shows that it's sending more watts back in than the current sensor is sensing. Am I missing something? Thank you in advance.
Kristoff Lutchman OK, something to understand....the clamp sensor is there to detect the total amount of energy your house is pulling from the grid on the 100 amp leg the sensor is connected to. It does not measure any of the power being produced by the inverter. It uses that value to determine how much power the inverter needs to produce. On the display panel of the inverter, the large number is the amount of power being produced and being fed into your home from your solar panels. The small number is the remaining amount still coming from the grid. In other words, if the clamp sensor detects 1000 watts needed by your home and the large number on your inverter shows you are producing 600 watts, then the small number on the inverter will read 400 since your are still needing 400 additional watts from the grid. On the other hand, if the clamp sensor detects a load of only 600 watts and your panels are producing that, then the small number on the display will show zero since no additional power is required from the grid. Does that make sense? Your kill-o-watt meter should display a number very close to what the large number displayed on the inverter is.
That does make sense. I guess I am confused because I did a controlled test using a kill-a-watt and put the current clamp on a circuit drawing 30 watts. Which was displayed by the little number on my inverter but with another kill-a-watt it was putting the full amount of solar panel power into the grid. Maybe it’s possible I have a defective unit? It just appears to display the same as everyone else’s I have seen on UA-cam, so not too sure.
Kristoff Lutchman Are you sure the limit option was enabled? I also have a whole home Sense meter that measures everything going on in my house. It has detected no power being fed back into the grid at all.
@@jimginnyohio I had the Limiter function checked as well as Internal limiter selected and the CT clamp plugged into the Internal port. My small watt reading was a positive number. I will mess around with it some more when I get some daylight. Getting a home sense is a great idea.
jimginnyohio hi sir will sensor work if i put it at AC shut off box, my main box too far away i just need it for AC unit thank you.
Thank you for all the info! I believe you've talked me into getting a single 2000w inverter to tie which would likely offset everything my 240v (split phase) mini-split consumes and more. Is there any reason a 48v battery couldn't be tied into this w/o other equipment? Based on the limited view of the display in this video, it looks like you can preset the voltage to a min and max? Electricity is over $0.20/kW where I am, so having a battery system to offset non-solar hours would pay for itself IF I don't have to spend much on other equipment. A 5 to 10 kWh battery would get me through the night and then some. If another 2000W inverter and panels is needed, I would consider it as well... but at some point the ROI gets questionable!
I have some 435W, 73 Vmmp/86 Voc panels I was considering using with the inverter(s). It looks like this should work. They push about 6 A each, I'm guessing 5 or 6 of these in parallel per 2000W inverter would be about all it would want (not to mention the wiring cost would start to become an issue at the distance I have to run with this low voltage).
Thanks for all the solar info on your channel!
I believe that would work. Although, I would run that thru a low voltage cutoff device so you don’t drain your batteries too low
@@jimginnyohio Thank you Jim! Any recommendations on the low voltage cutoff device?
@@ssoffshore5111 I don’t have a specific device to recommend. However, most batteries that are equipped with a BMS will already include this feature built in. If you are building your own battery bank, be sure to include a BMS and you should be good to go. Otherwise, a low cutoff module can do ordered from Amazon or AliExpress pretty inexpensively. Good luck with your setup!
@@jimginnyohio Roger that, thanks again!
@@ssoffshore5111 This device has low voltage cutoff built in. Default value is 44V I believe but I would set it higher.
Great video. Can you run the Sun Grid Tie Inverter with the limiter and not run the limiter? In other words be able to put the full amount of the panels into my home/Grid. I guessing that if you don't put more into the grid each month than you use and still have a small bill you wont be charged. I live in CA with Edison as my power company. They installed a digital meter a couple of years ago.
Thanks for the Great Video
Mike
Yes, that’s exactly what the limiter does. It puts all power into your home as needed but does not export excess power to the grid. If you disable the limiter, then any excess power goes to the grid if it isn’t being used by your home.
I am in Jamaica and we use 220V/110V split phase. I purchased an older version of the GTIL where the limiter was external. This was a 220V version. I am planning to purchase a identical CT and parallel it on the limiter, but placing one of the CT on L1 and the other on L2. My theory is that the resulting current will the vectorial sum of the two currents and would work properly. Is my theory correct?
My suggestion is to join this Facebook Group: Solar Grid Tie Inverter with Limiter USA Users
There are some great people there that have provided the details and diagrams for what you are hoping to do. I would hate to guide you an the wrong direction since I have not personally set up one of the 220V versions of those inverters. Good luck. I hope you are successful with your project!
Yes it should cause each leg is being measured instead of one out of two, Right now i have One GTIL 2000 connected to two legs by running them in series so far it works....
the consumption was more expensive for me rather! that I have badly connected
do you know where the ct sensor goes
I have 220 in the neutral, ground or positive phase?
I have this model
SUN 1000W Solar Grid Tie Inverter with Limiter Sensor Wi-Fi DC 22-65V 45-90V AC
since you now have the 2 inverters 1 on each leg do you see it running a 240v device ?
Joe B Whever my well pump, hot water heater, stove, or dryer come on, I see both of the units ramp up to deliver the needed power for those. It’s pretty cool. Wishing I had installed the second unit sooner! :-)
My SUN-2000W GTIL2 will not save settings after correct operations. Any ideas as to how to factory reset, or correct the problem. THANK YOU. Cliff
Thank you for your informative videos. It seems that things are never as simple as you'd think they'd be. I have 6 24v Renogy panels and was thinking of splitting them into 3 per inverter, but the open voltage of each panel is 31.4 Volts, which would put me at over 94 volts. Is there a little bit of wiggle room, or do these shut down when over 90 volts. I don't seem to be able to find a good answer. I could look at my legs to see if I draw on one side over the other and go 2x2 (4 panels) in Parallel and 2 panels on the other inverter. I will probably need to change the gauge of my wire though, plus add another run. Just more money... -lol
Yes, unfortunately, they do shut down when 90 volts is hit. You didn’t mention the wattage of your panels....
You could configure the panels with 2 sets of two panels each wired in series and those two sets in parallel if they are below 270 watts to get one inverter up and running and then just use two panels on your second inverter. Just an idea....
@@jimginnyohio sorry, yes 6-270 watt panels. Probably a set of 4 and a set of 2 and set them to the appropriate 120 legs by what gets the most current draw..
@@jimginnyohio Update! I have 2 of the 1000 watt units installed. I have one leg that seems to draw more than the other, so I stuck four 270 panels on it, and 2 panels on the other. On most sunny days, I have extra PV since the house sits at zero when not running any major appliances. I also have a Mppt LV2424 that I have connected to the grid only with a smart switch to float my 24 volt lead acid at about 2 amps for backup. Next upgrade is change out the 12 gauge wiring from the solar to the house. Thanks again for your videos.
@@ScottMartinez I'm glad to hear you have things running well! You mentioned you have the LV2424 connected to the grid??? I didn't think that was possible since that is an off-grid device. That's a great unit for backup power, but it's best to have that running thru a transfer switch so you don't have power feeding from the grid and the MPP device at the same time. That can cause bad things to happen. Is that what your "smart switch" is for?
@@jimginnyohio The hybrid 2424 unit is just setup as a battery charger to draw 2 amps for floating the batteries. These are on standby, and do not back feed. The inverter is also off. I did buy a transfer switch that I plan to wire the the inverter output to in case of a outage to run the fridge/furnace/lights. My bank of 8 Trojan T105's really don't have much gas, but I should be able to get a couple of days out of it if we lose the grid. I do want to make it so I can easily get PV wired back to the 2424 if the grid goes down for more than a day or so easily. The Suns do seem to be the best bang for the PV during the day. I can get the house to pull 0 from the grid in bright sun, and run all my "always on" loads, and still send the 2 amps to the 2424. The smart switch is so that the 2424 stops pulling from the grid after peak sun. The unit just shuts down, and the batteries maintain their charge. I hope that makes sense. Thanks for your informative videos!
Question - You said you have 4 X 255 Watt Panels hooked up . What are the Voltage of your panels and how did you wire it up to work under 90V. I also have two of these Grid Tie and I also have 250 Watt Panels which are 37V . Wanted to get some advise on wiring.
I connected two sets of two panels in series and then paralleled those two sets together. They are about 38V - 8.3A each. I used 10AWG cable to run to my house.
@@jimginnyohio Thats what I was thinking - Thanks .... Could I hook up 2 of these on the same leg and 2 more on the other leg ? For my house I would closer to 4000 Watt Grid tie .
@@alpereira7112 Some people have done that. Although, I’m not sure how accurate the sensor clamps would be in that configuration. You could accidentally back feed some power....gaining the attention from your power company.
Here at home I have two 120v phases and a neutral one. I have equipment that works with 120v (a 120v phase more neutral) and I also have some 220v equipment (two phases 110v) The 1000w grid tie limiter only injects energy in one phase, the 2000w 240v two phase grid only has a TC sensor for operation in two-phase 220v. How would I be part of a correct operation? It would have to be a 2000w 240v two phase 120v grid and two TC sensors, but it is not manufactured yet. Is it possible that by placing two 1000w grid tie limiter one in each phase, I can inject energy independent of the connected equipment? 120v (phase and neutral) or 220v (two phases 120v).
You "Should" be able to connect two 1000w GTIs, one in each phase. This way they would operate independent of each other. I know that some people have also had some success with connecting the 220V version of this. However, not sure if that one would work for your environment. Best wishes!
Thanks for the guidance. I have to take advantage of this strong sun here in Rio de Janeiro.
Hello! I just received my Sun GTIL inverter and once I connect it to AC (with or without PV) , it makes an electronic noise quite loud. I am discussing it with the seller but I'd like to have more opinions. Are your inverters noisy (not the fans)?
Joaquim Barrera No, not at all. The only sound coming from mine is when the fans spin up. It sounds like you received a bad unit.
If it's a low frequency inverter it could be the sound of transformer hum. If so, this is normal.
Do you know if it has DC input overvoltage protection? For example I see the DC input range is 48-90 volt. What if you connect two strings of 3 parallel panels whose voltage is 100volts when not underl load and 70Volts under load. Do you think there will be a problem with the inverter when not under load?
In those cases, it is “supposed” to shut itself down. However, since this is a cheaply built Chinese designed device, it would place a lot of faith in that! This is why I added my own protection devices.
thank you
Most likely it will throw a code!
So how does the inverter see both legs when it only has one clamp? Is it because you have two inverters on each leg or can one stand alone inverter read both legs? I think the clamps will work for me because it's only 50amp on each leg in my rv. My rv currently has off grid system, so I'd use my midnite controller Aux1 to power the grid tie once it detects charged batteries.
It doesn’t. Each clamp only reads the leg it is connected to. I have two grid tie inverters....one connected to each leg.
@@jimginnyohioThat is what I thought. Thank you so much for the reply!
@@jimginnyohio and I just realized if I want the 2000 watt inverter I'd have to rewire my 24v panels in series to get the inverter to work. Or buy 2 1000w inverters. Sounds like 2 1000w inverters would be best so I could read both legs and no need to put the panels in series. Being in an RV I'd worry about shading a series of panels and losing that whole string.
@jimginnyohio. Regarding the oldest inverter of your setup, for how long are u running this unit ? your first video that I saw on your channel is like around 2 years old, did u had any issues at all? where did u bought it ? I'm planning to buy it from eco-worthy on ebay, but if u can share your supplier and haven't had any issues, I will look up to get one from the same supplier u did, THANK YOU so much for posting this videos, greetings from Mexico
Menny Hello Menny. The oldest inverter I am running is 3 years old now. I have experienced no issues with it at all. I take it off the wall each year to clean the dust out of the fans, but that is about all I have done to it. Eco Worthy is a good company to deal with. I purchased one of my inverters from them. Good luck with your install!
@@jimginnyohio thanks for the fast reply
My grid tie invertor is 100 foot from my house service panel. do the make wires that long? would it work?
I'm talking about the limiter
Some people have made their own sensor cable since it is only two wires. However, it’s my understanding 25-30 feet is the maximum distance for reliability reasons. If you make it longer than that, it certainly will not be accurate.
cool
Do you have these connected in parallel or are they running independently from one another
They are independent, one on each leg of the power panel.
@Jimginnyohio. A few posted vids back it seems like you had a fire and at least one of the inverters was damaged from the inside. Someone asked you in a post if there had been a fire. As far as I know you did not respond to that question. Can you share what exactly happened?
BPS No fires here! I believe you are referring to Old Time Engineer’s channel. I know that he had a fire and was attempting to revive a couple of these units.
Sir I wanted to know if I can use 4 350 watt solar panel . I wanted to put in 2-2 parallel
I know you can go slightly over the rated wattage, but not sure I would go that high over the maximum since it might damage the unit.
How long is the cable on the limiter clamp?
The ones I got with my inverters were 10 feet long. I’ve heard of others extending theirs up to 25 feet with no problems. Anything longer than that may cause improper readings.
I notice that your limited GTIs have a second CT connecter. I've seen that they are labels "internal' and "external". What's the deal with these? How is the other used?
They have an internal limiting circuit that can be used as I have done. You can also purchase an external limiting device that can be used instead. Some people like using those since they offer more programming options. Here is a video of some using one of the external devices.
ua-cam.com/video/5Eg5dHtGqCs/v-deo.htmlsi=J6fmnG0d4DR7--md
I was thinking of buying 4 1000w inverters 2 on each leg. Can you put 2 clamps on 1 leg or wire 2 inverters on 1 clamp? I don't want to run the 2000w with 2 CT sensors at 240v The one guy on youtube who has done that in his later videos he had problems with it.
Placing 2 clamps on each leg will not work since they will not be aware of each other and will cause power to feed back into the grid. Instead, go check the videos posted on UA-cam channel "SolarEngineering". He has successfully connected two of the 2000w inverters using clamp sensors that are paralleled together. That's how I would do it if doing again. Good luck!
@@jimginnyohio So if you are pulling 100watt 120v from one leg and the inverter pushes back 100w at 240v would that not put 50watt per leg?
This video shows a guy successfully connecting 4 inverters 2 per leg.

The video you recommend the guy is not successful. His latest video trying to fix his problem dose not get fixed by the end of the video.
Hello Jimmy from Ohio, maybe you can help me I’ve tried several places and not had success. Being a very quaint novice I have purchased day box from MPP solar that was made for the European market (220 ) v .So I’m kind of stuck with it the only solution they gave me was to get a step down transformer no I don’t know where to put that and they don’t seem to want to help me I’m stepping down to 20 V to 120 I suppose what does that do for charging my battery.? Any advice you could give me will be greatly appreciated.
Percy Brown Hi Percy - I read where several others have had success going the step-down transformer route. However, I’m not really familiar with those myself since I’ve never personal done that. At one time I considered going with one of the European MPP devices because that was the only way to go 48 volts, but that has since changed. Try searching UA-cam for videos about step down transformer solar inverters. I wish I could provide more information to assist you!
is it ok to use without limter? how do i factory reset as "Today KWH" screen is stuck at zero even though itsbeen running for weeks sevearl kwh per day
Yes, you can run without the limiter. However, it might backfeed to the grid if you are producing more power than your home is using. Not sure how to reset it. Best to contact the manufacturer for details about that.
Why did you put a metal sheet at the back of the GTIL2?
Christian A Since the back of the GTIL is a heat sink, I wasn’t sure how hot it may get and didn’t want that in direct contact with the wood. The metal should help to dissipate the heat a bit. Just an extra safety precaution.
Dear Friend. I have 3 x 2KW 220Volt AC on grid tie inverters.I want to connect all these three inverters to my electric panel which has 1 x 40 Ampere Fuse coming from Grid. QUESTION A .As far as the incoming PANEL VOLTAGE to the inverter. I understand that i connect the 3 red on top the +ve from panels in parallel.And also the 3 black on top the -ve from panels in Parallel too.As i know the limiter ring goes to the Live 1 that i only have as i said One phase.Do i have to place each limiter ring in the same live 1 cable??? I beleive yes. QUESTION 2.Now as as as the out put of the 3 inverters is concerned Do i connect them in parallel??? I mean each brown (live) cable together. each blue (-ve) cable together and each yellow (earth) cable together ???? QUESTION 3 .NOW what about the limiter CABLES ......How do i connect the three ones. ???? if i dont mistaken ting that . QUESTION 4.What happens if i install 48 volt battery system in the future. Each inverter has a pair of a solar panel array giving hapilly 68,4 volts.Since the top connections of each inverter will go to the battery output because the source of energy now we define to be the battery.........where do i connect the 3 double cables coming from the panel arrays offering each 68,4 volts.???? I imagine each to a solar controller ??? and where can i find a controller for 48 volts or 60 volts , in case i add one more battery.....I have search everywhere No charge controller for 60 volt system.....Thank you VERY MUCH for your kind attention to my issues.....
Hi. Please note that I am not an electrician nor a service technician for this product. I am simply a consumer like yourself. I am not able to provide any advice for your particular setup since I have no experience with anything similar to that. I posted these videos in case others were interested in see how I configured my devices. Your configuration and goals appear to be completely different. I'm sorry!
I just read the comments and replys from How We Do It Here saying his smart meter was reading the power he was putting in and he was being charged for it. Is that true?
Maybe true for him, but not for me. I do not have a smart meter here. Although I’ve never hear of that happening for others with a smart meter.
@@jimginnyohio Thank you for the reply. They just installed smart meters 2 years ago here and I have never seen that before. I have been thinking about installing a few panels to help keep the bills down. Can`t get any info from PSO & Bidenomics is getting expensive for people living on disability. Probably going with a Growatt from Signature Solar.
Do these have a reset button? I have 2. Neither seem to be working any longer
There is no reset button, but you can power them down to reset.
You didn’t say how they aren’t working.
@jimginnyohio I have dc from the panels. The display is off. Fans not running. No power(amps or watts) showing thru the kill-a-watt. There was a storm at night. Next day neither inverter worked. I've unplugged them. Disconnected the DC input, turned the breakers off and on, left disconnected for an entire day and still nothing. The 2 fuses inside are intact and not blown. I could see one inverter, but not both. They were installed in January 2023. Any help would be appreciated. Thanks
@@brianj9262 It sounds like maybe you don’t have power at the outlet they are plugged into. Have you checked the ac breaker for the outlet?
Bro do you know how to factory reset the gtil inverters?
Search Facebook for the Sung Grid Tie Inverter with Limiter Group and look for Rogel Naval. He should be able to provide that information. Good luck!
Hello could you please help. My husband and I did a set up like you have and for some reason it’s still showing 0.0 wattage and we don’t know why? Could you help please
That would be hard to do without seeing your setup! Do you get any reading when running the
panels directly into the inverter and the inverter plugged directly into power outlet…bypassing all of the safety devices?
@@jimginnyohio thank you for replying so fast, yes we did that. The only reading we are getting is I think from the limiter and then when the sun was up we were getting the volt reading from the solar panels and 0.0 for wattage. Maybe you could help my husband tomorrow when the sun is up? You can call him if you would?
@@amikkadisciple which model of the inverter do you have and what is the voltage rating for that? You should be able to see that on the sticker. Also, what voltage level are you seeing on the display? Also will need to know your solar panel ratings and configuration.
@@jimginnyohio we bought the 1000 watt and 45-90 volt. The voltage level we are seeing on the display is 68.4 and we have 3 panels for now and they are each 100 watt and 24.3 volt
Thank you for trying to help! It is much appreciated.
Dear friend.Hello.Have you got any idea how we can find the PIC 24F 16KA 102-I /SS 1845 CAB which is programmable and encryptic chip.This chip belongs to MICROCHIP USA company.And Actually my seller is not providing me to repair my computer.And he tells me to buy a new motherboard price 350$ just for the sake of a small chip 2$ cost .Thank you it is positioned next to the fans and its exact motherboard number is U11
On a 1000W inverter with 4 350watts panels.
Nice video like all the others.
Somone told u look like Rusian president ?
current updates?
I have two of those grid tie inverters. I have had them for 10 months and one failed today. It constantly reads 0 watts no matter what. The company will not respond to emails and amazon won’t do anything about it because it’s outside the return period. The amount of money I saved from the inverter is about 130 dollars in electric bills, which isn’t even close to paying for the cost of the gti. This was not a good investment.
Sorry to hear about that. Yes, I have heard from others with similar problems with these inverters. In most cases the issue is with the mosfets that handle the incoming power. This is why I went to the extra time and expense to add the protection devices I posted in a previous video. Regarding the amount of power/money you saved over the 10 months of running the inverter, please keep in mind that your return on investment will not be instantaneous. With most professionally installed systems, the payback date isn't for about 14-15 years. By doing it yourself, you are still looking at about a 7 years return on investment. Please don't give up on solar! It works! Good luck!
I also had bad luck , I have a single one , worked great for around 2 months , then started ramping up and down on the power generated . I had to keep on dropping the output wattage setting but now it is at a stage where it just ramps up and down from 0 to 10watts . Mine was purchased from ALI and I do not get any joy from the supplier. Pity it seemed like a good unit but with no after sale support its just money wasted.
could you physically help me build my system?
The only thing is after 8 episodes your video stopped I could not see episode 9 10 11 12 13 14 15 16 or 17 what happened to those episodes all we have is episode 1 2 3 4 5 6 I think and 7/8 and nothing until episode 18 I like how you're sitting up your set it's not exactly what I would do in some sense but a lot of things you're doing I would do anyways because that's just the right way to do things for some things like how your hooking up all your inverters just a little bit too small of inverters but you are making your house real safe and I like that I want to know how to hook up breast systems for the way you would do it so I have a better idea how to do mine even though I already have an idea how to do mine I mean I do have some solar panels high more than you do it the way it sounds but your picture shows that if I have more than I you just got to have you just have smaller inverters than I would have and you really explained everything out real nice nice to the most videos would. But I don't think you're going to see this but if you do I would like to see the other videos that I didn't get to see on your solar installation and the rest of your inverters installations and so on and so forth with that.
Not sure why you’re not seeing those videos. They are indeed still posted on UA-cam. Just try doing a search for DIY Solar - Episode #
@@jimginnyohio Raven looked on your playlist and it's not on there it got all the other stuff I don't want to see on your playlist I only want to see what I was asking for cuz they're very explicit very detailed and words explain some things that I do know and a few things I may not know I'm looking for dry episodes for solar won't show you up on my phone and I do not know why.
@@acefire4050 Like I said before, search in UA-cam for: “DIY Solar - Episode #”
You must type it EXACTLY like that except replace the # symbol with the episode number you wish to see.

I also have setup 2 1000 watt gtil2 inverters. What's the highest wattage you've seen then push?
DIY Dan I saw 840 watts on both of them today. I plan to wash my panels this weekend to see if I can push it a bit higher.
I guess I'm a little nervous of going that high, I'm staying below is 700.
DIY Dan I've been running the first unit for over a year and a half with no problems. Just be sure to keep the fans clean and running well.
since you installed your solar how has it reduced your electric bill ? thanks
These two inverters reduce my power bill by about 25% on average. I’m considering setting up batteries to handle some of the after hours usage. That should help reduce my power bill further.
