Yes.... complete the demonstration with the remote gen start and how much current from the solar array can you input? This looks like a simple solution for a remote cabin to start power tools and keep a fridge running ..
What is that loud hum noise.? That's obnoxious as . Also, I know LF inverters have a higher idle consumption, and that's fine, but that's close to the consumption of my 10kW AIMS. Great video and great tests though!
~165 watt draw at idle seems terrible for modern inverter specs. Was that noise as annoying in person as it came through in the video? I was actually looking at getting this exact inverter from Sigineer for use as a UPS for my server/network while using as much solar power as possible to offset usage (no net metering or utility company interaction required). That would probably be the best configuration for this inverter if you can set it to fail over to utility power when the battery is depleted. I'd like to see if you could set it up that way.
I was going to point out the same things - low efficiency and that bloody noise. I figured it out though - the 165W goes towards creating that noise - now all they have to do at Sigineer is tune it towards making music rather than buzzing noise. I suspect they need to do more work on bonding the laminations in that huge transformer.
I went with a pair of the Growatt inverters, 3kw each, can be paired for split phase or to boost power for single phase. They are pretty quiet, no buzz, just a bit of fan noise depending on how hard they are working at either inverting or pulling power from the pv array. The usb software is not great but the wifi dongle and it's app work very well with detailed stats. You can set them a few different ways so that it'll switch back to grid at a certain low battery voltage or if there is no pv being generated. I have mine set to charge from only solar and on a sunny day by 9:30 the battery is high enough that it stops pulling power from the grid and runs everything off the solar and stored power in the batteries till about 8:15 at night when its dark enough that there is no pv voltage coming in and then it switches back to the grid. I have about 8kwh of storage right now connected with a 4kw array currently and by the time it switches back to the grid i've still got 5-6kwh remaining in the batteries for any power outages. If the power goes out it switches to the batteries just like a ups with no impact on the computers running. I have a 12,000btu mini split unit and an 18,000 btu mini split and a 6,000 btu window unit all on the two inverters, my fridge, 3 chest freezers, my washer and gas dryer, 3 computers, home theater, two ceiling fans and the lights in half my house on my pair of inverters and basically on a sunny day I pull nothing from the power company for almost 12 hours of the day. The mini splits are 240 volt, everything else is 120 volt. Each inverter can take up to 4500 watts of solar. If a storm is coming through I can switch them to charge from the grid and solar, it'll charge from solar first and then top off with the grid at the end of the day so the batteries are full should a storm hit. They cannot feed back to the grid so there is no issue there since I lack net metering as well. I've not tested them with high draw loads like a miter saw because as rarely as I use such I just power those from the grid. The cost a couple hundred more than this inverter but they have no buzz and have a pretty low standby draw. They are a high frequency design.
@@MiniLuv-1984 the problem is not as much the bonding as the use of an E core former. E cores are inherently more noisy and less efficient when compared to their toroid core counter parts. But the drawback of toroid cores is the price. I ditched my south african made micro invertor which was 20k less than the Victron I now have hung on my wall because of just that reason, the noise, in my living room none the less. But, if on a buget and there is an out building, this for someone just starting out that does not have allot of capitol..... Not to bad an option, I have seen allot worse...
Is that a great surprise? Never seen you exude so much pleasure watching your saw start. So many disappointments in previous attempts. Congratulations to a great accomplishment and find. Loved this video. Your reaction is priceless!
4.25.20 Great video David. Was real impressed when using the saw and vacuum. Yes please do another video on using the USB to hook up to something. Thanks again.
if anything these shows the resiliency of the normal electric grid. Thanks for the great videos david. Makes me really want to make a setup like yours.
I can tell just by looking at that unit it looks like its heavier duty than most, especially for only rated at 2500w and the cable is so slightly over rated, nice to see. Great video as always david! Keep it up
Yes, you are absolutely correct. Low frequency, transformer based inverter/charger offer a much higher peak power capacity and a far longer life expectancy than cheap, lightweight high frequency inverters. And by the way, we've done some extensive testing on the Sigineer brand of low frequency inverters and found them to be an excellent product.
@@DavidPozEnergy not their yet. How does the MPPT look? Can you make a continuation? I do live that it starts the miter saw. This adds tremendous creditability to the performance and hopefully it will start the 2 air-cons on the house.
Hey David! Good video Mate, just giving my 2c worth. On the scope. I would expect to see a great deal of noise or ripple when starting something like the high current miter saw. There are a few reasons I say this, 1: you are the only user on this small little "grid", 2: because the "grid" is so small in capacity it does not have the capacity to be able to deal with heavy loaded start up's that cause allot of noise or ripple current (also akin to back EMF). If you do the same test on your national or municipal grid you'll still see noise but it should be allot less because of the megawatt current capacity of the grid, then, the other houses on your phase or phases if you have 1, 2 or 3 phases would help to soak up allot of the noise generated by your saw or ac compressor that by the way also creates a huge amount of noise or ripple current, there are a few factors that carry over to this. The one reason I would say that the inverter is so "loud" is I think because of the use of an "E" type transformer and not a toroidal core, the Victron uses two of them 220Vac 5Kw and is virtually silent. None the less for a budget buy that is not a bad option for a low cost setting, you were at one stage pulling 3,3Kw on the AC side which for a 2,5Kw unit is not bad at all that is basically 3/4 of a Kw over what is should handle. Good review!
David, I devour these kind of shows, just for the little things I learn. It brought a smile each time I saw you get excited when a shop tool started on the low frequency inverter. Good luck! And thank you for taking the time to make these videos.
HI David, thank you for this review. I got this one, but 2000 watt, plugged to 1000 watt of solar panels and 4 100 amp 12v agm´s. Could not find anywhere the name, brand or anything. It is very robust, but two things I really don´t like: Idle draw, and the fan. It´s very annoying, since I have it inside our cabin (maybe upgrade it to a silent pc fan). I feel that the idle draw is affecting negatively the charge of my batteries at night, may need to upgrade my system a bit, but would need 4 extra batteries, and some extra solar, to offset it´s idle draw. Could you test the inverter with some ac variable speed tools? I can run everything, but 1 bosch variable speed drill, which will make the inverter shut off.
I have a sigineer and there costumer service is amazing. Have had a few issues. And they have sent me replacement parts for free. Just had to pay shipping
heya that is a nice power ogg grid solar inveter but I'a still connected to the grid so I'm looking for a inverter that as the batteries are full I still can give back to the grid
i'd definitely be interested in the USB > PC functionality and the software. I am currently using the LV5048 inverter and it works great but as in your previous test with that inverter I am running into the same issue with my miter saw. It switches over to grid automatically when I power on the miter saw. Not a huge deal. On the other hand the MPP solar software is pure garbage so I'd be interested in this aspect for this inverter.
Yes I've been talking with Franklin for a few months at Sigineer as they allow AC coupling and 240 split phase but they don't have the battery range I need but they seem really good and the price is right. Thanks for the video
Ive also been talking with Franklin for a few months. Going to buy the 15kva split phase inverter and another HF inverter possible the mpp LV5048 split phase for its pv charger and use it to power more sensitive loads while the LF inverter powers more heavier loads. Plus, the mpp inverter seems to have more exact charge options for my battery bank.
I don't know of any 60v inverters I'm really happy with. But there are several 48v inverters that go up past 60v I like. Several models go up to 64v which is good enough, but some go higher. The Magnum MSPAE will go up to 68v. That's sweet.
DavidPoz check out threads on anotherpower.com. The forum is a bit dead but there are some good reads. Some of the guys have built their own inverters and I’ve heard of 96v inverters.
@@billssolarpowerandgardenin1016 It is not a true inverter but I just got my hands on a APC SURTA3000XL UPS and it runs off of 16 12V 5ah SLA batterries which were dead of course. That means it takes 192V DC to make it run. I bought some 3.7 cells from Battery hookup w/ BMS and plan to try and revive it. It should be a 3Kw Pure Sine Wave when I get it running.
First thought was the noise. And I sure wouldn't want to Lug the thing around. BUT... You can't hear it over the chop saw😲😁😏 And for a down and dirty unit it'll get the cabin built and a lot more. So actually it's a pretty good value. I'd buy one if I had a need. Great review as always 👍
Hi David! I am using 4 panels of 260 watts 30 volts 15amps (REC 260 Peak Energy Z-link series). My Solar controller charger inverter is PowMr 60amps 3000 watts 48 volts with PV input of 145 volts. Using 14s Nissan Leaf batteries with BMS 48 volts. Should I do series of my 4 panels to make total of 120 volts or series 2 panels total 60 volts then do a Parallel for 4 panels? Advice from will be really appreciated from you thank. Gerry
More details the better! It allows us to decide if we want to buy one. I really like the MPPT from your friend. I will be building an offgrid system with 3 of those.
I'm considering the Sigineer 3,000 Watt, 24v inverter, charger, MPPT charge controller and the GroWatt with the same specs. Do you have any thoughts on quality and features of these units? I'm looking to use them on an RV with a 2kw panel array and may add a generator to the system. Or can you recommend other brands?
When you loaded the inverter down with the Vac and Miter, what was the load on the battery side? Is it possible that you reached the max amps capable on the wire or had too much voltage drop from the load and not the max load the inverter could handle? I didn't notice what size wire you used on the battery side to make sure you didn't overload it. Assuming a 48VDC input and 3400W pull, that'd be 71A on the batteries/wires. This is an estimate and most likely a bit low because the digital meter wasn't updating fast enough to keep up with the constant changing power draws 10:35. You can hear the beep of the inverter for a second or two before the meter updated. So it's quite possible the amp load was much higher for that second or so.
Bit of a strange pop when you connected the batteries.. Id be interested to see the remote gen etc. I wasnt expecting it to start the saw tbh but it did well
Hi Dave - wondering how this product is doing. Thinking of making a purchase similar (24v). Used to think MPPT was the way to go - but after reading amazon reviews - I think I want to steer clear of them. Would love an update on this inverter/charger.
For the buzzing/noise of the inverter, it's possible to quiet it down. Take the transformer out and make sure there's some rubber padding between it and the case. And have some hard rubber bushings at the screws. Might even need some rubber padding where the boards also come into contact with the case. Also, make sure there isn't space between the covers and the chassis as this is another spot of possible noise generation. So again, a little bit of rubber padding (thin window weather seal perhaps) to make sure it can't vibrate against itself.
Did you ever invest into creating a small DC grid in your house for DC devices? I'm wondering if it is more efficient when running DC devices from batteries with a DC-DC converter instead of going from battery DC -> AC -> back to DC. Would love to hear your thoughts and maybe create a small expiriment in the future.
I have an mpp solar one and it does not get off utility when the sun comes up, and it waste a lot o energy. I had to turn the 800 watts pure sine wave inverter on mine. the mppt charge controller work really well but if you start using energy the fan is very loud.
hi i want to ask you if i can run this inverter with lithium battry 18650 24v with bms and charge it in the internal mppt charger in the inverter thanks for help brother
Glad you got something from that outfit, I got one similar turns out it was a 240v model still got it stuck with it still need one but I won’t buy from them.
That noise on your oscilloscope is probably just the back EMF (electrical noise) pushed back into the wiring by the motor starting up. You can try my theory by attaching the same setup to grid power.
My friend, Ben, uses a Sol-Ark 12k. It's top of the line for all in one units. However, it comes at a premium in cost. I've tested MPP Solar LV5048 before and didn't like it. So If I was to pick one right now and didn't have the funds for a Sol-Ark, I'd buy a Phocos 5k. lddy.no/s5eo But I plan to test more of these all in ones during this year to get a better answer.
Great David. You made me laugh several times. Always like it when you pull out your power tools to test with. Nice video Keep them up. Waiting for the 2 inverters to get hooked up soon. Thanks
Hey and thanks for the video. I got a question... so the machine is rated fo 48v battery and you battery is over 57v, i also notice you programe the charging controller to charge the battery up to 58v. is best to use high capacity batteries?, if wanna set up a 24v system i can confortable use 36v batteries?. Thanks.
When we say 48v inverter, or 48v battery, we are talking about the "nominal" voltage. All the equipment must be the same nominal voltage to work together. But the actual voltage will vary at any given moment in time. Voltages of the battery are constantly changing and the inverter has a range it can work with. I think this particular unit can work with a range of 42-64 volts. You will have to check the specifications of your particular unit and battery.
@@DavidPozEnergy So if the solar inverter have a range between 24v to 48v charging the 36v batteries will be fine?, i will double check everything. Thanks.
I am curious to know if the unit is UL or ETL listed? I am always concerned when I see foreign language markings on most components.... I saw CE markings in the video...
I wonder what would happen if you put a super capacitor bank in your system to take the initial brunt of the power requirements. would be interesting to see.
Nice man. I’m looking at their 12Kw version. I was aghast at the buzzing sound when you turn it on. Is it really that loud? Planning on using it near a sleeping area and hope its not going to make that kind of buzzing when I’m trying to sleep!
I would NOT use this near my bed. It's the loudest inverter I have tested, similar noise level to a window AC I think. One of my cameras microphones was really picking it up. This inverter uses a cheaper transformer (E-style). There is another style out there called toroid, but is used in more expensive inverters. The toroid is much quieter.
DavidPoz Ack! Ok thanks for the great info. Ill ask about the different styles before I buy. For instance, I understand the 15Kw (singineer) inverter is much quieter.
Hi David, I enjoy your videos, very informative. Have a question about this inverter and the 8000 relaible, which one should I buy? I work with power tools like your saw, for home projects.
I would buy this one for temporary situations. Where you only need to power a tool once in a while, then it gets turned off. If you need the inverter running 24/7, then this one is not the right choice. Buy one that is more efficient, like Aims, Outback, Victron, Magnum.
Want to convert my van so i can run a mig,tig or stick welder from an inverter. What would be the best inverter to use and also what would you say the best brand of inverters is regardless of cost ?
Down that low you might be looking at "Micro inverters". I have some of the first enphase micro-inverters that are still running well. But I don't work with grid-tie inverters enough to suggest one brand over another.
@@DavidPozEnergy thanks David, I appreciate the feedback. I found a nice enphase thats about what I want, but was told 'used' could be a problem due to how they can be tied to networks. The model I was looking at can't be had new. Do you find the need for a central controller a problem with yours? Could you share which model you are using? Thank you!
My model is the 215 (I think) installed 8 years ago. I don't even use the central controller thing. I've never been on the "portal" because you need to give them your information. Mine just turn the meter backwards and that's good enough for me.
That is great demo.. Instead of pv input.. Can I use dc coming from my alternator 48 v? Also can same applies on battery input? Replace with power source from. Dynamo 48 dc volt
The input DC voltage has to be higher than your pack voltage. I was charging about 58v, so I would need at least 68v or more coming in. I don't know if your alternator can do that or not. But the battery must be a battery.
I can ensure that about voltage from alternator is higher .. Coz before I was warned by suppliers not to use charge controller with any input dc... Just was surprised.. That why I did ask you
THIS IS ONE HEAVY DUTY LOW FREQUENCY INVERTER LIKE THE AIMS THAT CAN RUN LARGE LOADS AND HAS A PV CHARGER . BUT CAN 2 OF THEM BE HOOKED UP BY A DATA CABLE LINK LIKE THE MAGNASINE INVERTERS FOR 220 V ?
shame it is not a 240v version as thats our power in the uk i do like these units i like how thay can run solar and flick over to a generator when needed or even hydro instead of solar what was the max ampage for solar
If you can plug it into a normal 120v outlet, you can probably run it on this unit. Most outlets are 15 or 20 amps. At 120v that's up to 2400 watts. This inverter is 2500 watts,
@DavidPoz - I have a suggestion David. I have a heater that ramps up very slowly in power (like 1 to 2 minutes to go from 300W to 600W on the low setting but I will check to get it more exact), and is good for finding out a maximum power of an inverter by already getting it close to the rated maximum using loads you already have, and then firing up the "ramp up" heater and monitoring the total wattage. I will test out the heater again and send the make and model so maybe you can get one locally there and use it for testing (and actually as a heater too), or maybe I can just send you mine since I don't use heaters much here,
Thank you for the review of the inverter. Nice that it is a low frequency type and can handle large start up loads. The auto generator start up would be nice to see but not because I would be interested in buying this particular unit. That very loud transformer would keep me from purchasing it. I think the better brands use a round toroid transformer. Also the standby current seemed rather high. I would like to see how it compares to other Low frequency inverters.
Hello mr. Poz!! It is that noise coming from the fan or its the internal components like transformer or any induction noise? Also want to say very good video and thanks for sharing your findings with Sigineer inverter cause I recently purchase one and hope to have it soon 👍🏼😎🇵🇷
DavidPoz I understand that, microphones pick noise that we normally don’t hear loud because of the induction or magnetism, as of i saw in the video the inverter is tough working above the parameters or at least neart to the maximum capacities
looks like a nice inverter! the only thin I dislike is the idle draw is to high, but the surge is amazing and I do like this company I have the 6000w and its working really well now. if your using this to just run tools i would buy it.
That label on the transformer at 4:21 is wrong since no transformer can convert 48VDC to anything other than heat. I know it is probably just an identifier for the whole unit.
The biggest problem seems to be the limited voltage on solar panel input. Followed by stand by consumption, efficiency and noise. It’s not that unusual for a hybrid inverter to be inefficient compared to a grid tied solar inverter.
Well done video. You should really speak more about the bloody awful huge 123W no-load draw for only a 2500W inverter. No load draws are a good measure of the quality of a inverter and by that measure this is a terrible one. Wouldnt own one if you gave it to me. In example my Samlex 2224 has a no load draw of ~30W - and even though it costs almost twice as much as a Sigineer its still cheaper than having to add the extra panels and battery capacity to support that constant extra daily 2.9KWH load. And a better quality inverter will last longer.
Good morning David there is not a single video that I miss, I have all seen them I try to imitate you in my house in some things that you do you are my source of inspiration, everything you do is excellent, I live in Colombia and it is not easy to get at a good price everything you teach I have a small 24v solar system and I have bought 48v lithium batteries I am needing that inverter to start the pair of 48v batteries that I buy there will be some way to buy it and send it to my country Could you help me?
Thanks for watching my videos. I'm not selling this right away as I have some other things I want to do with it. Does Colombia use the same 120v, 60 htz power?
@@DavidPozEnergy Good evening, friend, David. Thank you to answer me so quickly, if in Colombia we use 120v at 60hrz in general and 220v in a few appliances such as air conditioners, but my consumption is at 110v-120v throughout my house, I would like to have that inverter inform me how I could acquire it. in the best possible way since I tried and they only ship to the United States and not to Colombia
HEY DAVID, nice. I almost bought from them, nice inverter. IM glad you like it. And of course, I ended up with the Magnum inverters. You will like my set up. IM putting a video up soon. Keep up the good work.
@@DavidPozEnergy OH yes, so quiet too. I never really realized how much noise some other brands made. But I was impressed with the company Sygineer's inverters. They make them vast in options and abilities. There are a few others.
Pls do review generator remote start and the usb output into computer so that we will know alot more. Im trying to set up my off grid in the Philippines with hopefully they have the 220 volts 50 to 60 hertz spec. Thank you very much..
well dam signineer got there money worth with sending you this inverter. . . . its nice when a unit is tested hard and performs flawelessly!!!!!!!!!!!!!! one note tho, the link you posted is going to a different model that cost like 1200$
Generally speaking HF (high frequency) inverters are more efficient than LF (low frequency) inverters. HF is also cheaper to buy. But LF is better at handling surges, such as air conditioners and tools.
Both can produce pure sine wave, 120v AC. So both can be used. It depends what you plug in. If you only use things like heaters, TV's, lights, computers, then you can use a HF. But some things need the LF (transformer based) to start the big surges like AC, compressor, Saws. HF is smaller, lighter, cheaper. LF is bigger, heavier, more expensive. These are generalizations I'm making. The industry is moving to HF for everything as the computers get better and faster to react. Like the very expensive Sol-Ark is HF, but listed to have a very respectable surge.
Thanks for the videos, I am building a battery just like this and want to use the 6kw sigineer. When u were setting up the charging voltage with the solar, does that apply to the ac in also?
LOL, of course you say that. You are a computer genius. I'll try, but I struggle to get things to talk to each other. That was really nice of the line worker to say you are all set with your gen tie.
@@DavidPozEnergy You asked :) Ya they are cool. We are with out power still looks like for the next 3 days. No need for the geny yet tho. The suns out and it's not all that hot..
@DavidPoz - Hey Dave. Seems like a nice unit. It will pay for itself when you cancel your gym membership. What is the maximum charge current rating on it for a 48V battery bank? How many amps is it rated at (assuming you have enough PV power coming in to cover it)?
Specs say max 65 amps charging, or 3500 watts of solar PV. That's a lot more than I tested it with, but I didn't want to build a whole combiner box to parallel more strings.
@DavidPoz - That unit might be a good size for me for when I retire overseas because I need to ship it in a box of size 24x18x18 inches so it would fit nicely in there even double boxed. I already have powerful 110V to 220V voltage converters that should work well with something like this Sigineer combo product. Luckily where I am going overseas, they also use 60 Hz AC, just 220V instead of 120, so my voltage converters will be very handy (they can do both 110 to 220 and 220 to 110 (both ways). i sent some there already to my fiancee and she said they are working well (I sent her some 120V stuff from USA).
Let you know if you need any replacement parts under warranty from this company you will have to pay a very high shipping cost. My remote went out for my 6000w inverter and just for replacing it was $70 in shipping. Great inverter but very expensive warranty if anything goes wrong.
I've always wondered why you'd not opted for an inexpensive soft start module long ago. I've previously commented as such. This would solve the high in-rush current issues with your power tools. As for this inverter/charger, the parasitic consumption, while totally understandable, is too high for my off-grid applications. The hum from the transformer (also understandable) is crazy loud, as well! Lastly, I'm philosophically opposed to the single point of failure that combination devices represent. While they can admittedly take up less space and simplify wiring, I'm just more comfortable with discreet devices performing better overall due to device optimization, and less of a concern to cut corners on design and/or cost. It's been my experience that any device performing multiple functions usually does so at some cost somewhere. Coupled with the old adage that "you get what you pay for", the performance and total cost of ownership usually disappoint over the time. Anyway, that's my 2¢. Be well.
Hi John, I agree with you. This is not my go-to for most situations. We are both fans of SMA and it is a totally different league. I do, however, think there is a place for everything. I think this would be great for a tool truck, or tool trailer with a few panels on the roof and the occasional use at jobsites that don't offer grid power.
@@DavidPozEnergy Thanks for your reponse, David. I actually design, build and support portable worksite power systems from single-phase 120V/split-phase 240V, to three-phase 208V/230V. Total capacity varies based on load, quantity and duration requirements. For value-based systems, I typically employ soft starters. For larger systems, I parallel inverters such as PIP models from MPP Solar. With these, I can parallel up to nine units in single-phase configurations. Up to six units are supposed for three-phase configurations (48Vdc input only). The largest systems run a multi-unit condenser and multiple commercial and residential air handlers in custom-designed trailers used in mobile marketing by a major inverter A/C manufacturer. Nearly new Tesla packs, charged via solar or mains power, supply inverters powering various single- and three-phase 230V loads. Multiple inverters provide ample current, while Variable Frequency Drives perform phase conversion for the condenser. I was able to supply two trailers for the price of one of their previous truck-based platform that required shore power. The trailers can go anywhere and require no set-up as they're 100% off-grid.
Yes.... complete the demonstration with the remote gen start and how much current from the solar array can you input? This looks like a simple solution for a remote cabin to start power tools and keep a fridge running ..
What is that loud hum noise.? That's obnoxious as . Also, I know LF inverters have a higher idle consumption, and that's fine, but that's close to the consumption of my 10kW AIMS. Great video and great tests though!
I noticed the hum more on the transformer side compared to the other side, so I'm guessing it's from the transformer, but I don't know for sure.
~165 watt draw at idle seems terrible for modern inverter specs. Was that noise as annoying in person as it came through in the video? I was actually looking at getting this exact inverter from Sigineer for use as a UPS for my server/network while using as much solar power as possible to offset usage (no net metering or utility company interaction required). That would probably be the best configuration for this inverter if you can set it to fail over to utility power when the battery is depleted. I'd like to see if you could set it up that way.
Hey frist time checking in, like the inverter but that sound is problem, like the fack that It took the load that was applied to
I was going to point out the same things - low efficiency and that bloody noise. I figured it out though - the 165W goes towards creating that noise - now all they have to do at Sigineer is tune it towards making music rather than buzzing noise. I suspect they need to do more work on bonding the laminations in that huge transformer.
I went with a pair of the Growatt inverters, 3kw each, can be paired for split phase or to boost power for single phase. They are pretty quiet, no buzz, just a bit of fan noise depending on how hard they are working at either inverting or pulling power from the pv array. The usb software is not great but the wifi dongle and it's app work very well with detailed stats. You can set them a few different ways so that it'll switch back to grid at a certain low battery voltage or if there is no pv being generated. I have mine set to charge from only solar and on a sunny day by 9:30 the battery is high enough that it stops pulling power from the grid and runs everything off the solar and stored power in the batteries till about 8:15 at night when its dark enough that there is no pv voltage coming in and then it switches back to the grid. I have about 8kwh of storage right now connected with a 4kw array currently and by the time it switches back to the grid i've still got 5-6kwh remaining in the batteries for any power outages. If the power goes out it switches to the batteries just like a ups with no impact on the computers running. I have a 12,000btu mini split unit and an 18,000 btu mini split and a 6,000 btu window unit all on the two inverters, my fridge, 3 chest freezers, my washer and gas dryer, 3 computers, home theater, two ceiling fans and the lights in half my house on my pair of inverters and basically on a sunny day I pull nothing from the power company for almost 12 hours of the day. The mini splits are 240 volt, everything else is 120 volt. Each inverter can take up to 4500 watts of solar. If a storm is coming through I can switch them to charge from the grid and solar, it'll charge from solar first and then top off with the grid at the end of the day so the batteries are full should a storm hit. They cannot feed back to the grid so there is no issue there since I lack net metering as well. I've not tested them with high draw loads like a miter saw because as rarely as I use such I just power those from the grid. The cost a couple hundred more than this inverter but they have no buzz and have a pretty low standby draw. They are a high frequency design.
i think you could prob use the gen feed to trigger a relay for mains input if it want auto charge when low if solar is not upto it
@@MiniLuv-1984 the problem is not as much the bonding as the use of an E core former. E cores are inherently more noisy and less efficient when compared to their toroid core counter parts. But the drawback of toroid cores is the price. I ditched my south african made micro invertor which was 20k less than the Victron I now have hung on my wall because of just that reason, the noise, in my living room none the less. But, if on a buget and there is an out building, this for someone just starting out that does not have allot of capitol..... Not to bad an option, I have seen allot worse...
Is that a great surprise? Never seen you exude so much pleasure watching your saw start. So many disappointments in previous attempts. Congratulations to a great accomplishment and find. Loved this video. Your reaction is priceless!
Is this unit FCC part 15 approved? Lots of inverters cause EMF noise which is regulated via the FCC rules Part 15 in the set of rules.
Thanks
4.25.20 Great video David. Was real impressed when using the saw and vacuum. Yes please do another video on using the USB to hook up to something. Thanks again.
if anything these shows the resiliency of the normal electric grid. Thanks for the great videos david. Makes me really want to make a setup like yours.
Nice your really getting in the demo of equipment. Now we need to try out the YIYEN 18,000 watt split phase coming out soon !
I can tell just by looking at that unit it looks like its heavier duty than most, especially for only rated at 2500w and the cable is so slightly over rated, nice to see. Great video as always david! Keep it up
Yes, you are absolutely correct. Low frequency, transformer based inverter/charger offer a much higher peak power capacity and a far longer life expectancy than cheap, lightweight high frequency inverters. And by the way, we've done some extensive testing on the Sigineer brand of low frequency inverters and found them to be an excellent product.
So you would recommend one over a EG4 6000xp
I've been looking at these for a while but haven't pulled the trigger due to not knowing enough about them. Thanks #DavidPOZ for the great info
I hope it helped you decide one way or the other.
@@DavidPozEnergy not their yet. How does the MPPT look? Can you make a continuation? I do live that it starts the miter saw. This adds tremendous creditability to the performance and hopefully it will start the 2 air-cons on the house.
I have the the Signeer 6KW 120/240 split phase unit and it doesn't have the noise problem that this unit exhibits.
Hey David! Good video Mate, just giving my 2c worth.
On the scope. I would expect to see a great deal of noise or ripple when starting something like the high current miter saw.
There are a few reasons I say this, 1: you are the only user on this small little "grid", 2: because the "grid" is so small in capacity it does not have the capacity to be able to deal with heavy loaded start up's that cause allot of noise or ripple current (also akin to back EMF). If you do the same test on your national or municipal grid you'll still see noise but it should be allot less because of the megawatt current capacity of the grid, then, the other houses on your phase or phases if you have 1, 2 or 3 phases would help to soak up allot of the noise generated by your saw or ac compressor that by the way also creates a huge amount of noise or ripple current, there are a few factors that carry over to this. The one reason I would say that the inverter is so "loud" is I think because of the use of an "E" type transformer and not a toroidal core, the Victron uses two of them 220Vac 5Kw and is virtually silent. None the less for a budget buy that is not a bad option for a low cost setting, you were at one stage pulling 3,3Kw on the AC side which for a 2,5Kw unit is not bad at all that is basically 3/4 of a Kw over what is should handle. Good review!
Thanks. That makes me feel a little better about my Scope setup.
David, I devour these kind of shows, just for the little things I learn. It brought a smile each time I saw you get excited when a shop tool started on the low frequency inverter. Good luck! And thank you for taking the time to make these videos.
Thanks for watching and your comment. I've had my share of inverters not be able to handle the power tools, so I love when it works.
Yeah David what this guy said 👍
165w idle and noisy as hell .... no go.... Thanks David for your excellent review.
HI David, thank you for this review. I got this one, but 2000 watt, plugged to 1000 watt of solar panels and 4 100 amp 12v agm´s. Could not find anywhere the name, brand or anything. It is very robust, but two things I really don´t like: Idle draw, and the fan. It´s very annoying, since I have it inside our cabin (maybe upgrade it to a silent pc fan). I feel that the idle draw is affecting negatively the charge of my batteries at night, may need to upgrade my system a bit, but would need 4 extra batteries, and some extra solar, to offset it´s idle draw. Could you test the inverter with some ac variable speed tools? I can run everything, but 1 bosch variable speed drill, which will make the inverter shut off.
I have a sigineer and there costumer service is amazing. Have had a few issues. And they have sent me replacement parts for free. Just had to pay shipping
Fyi I love mine... idle consumption could be lower but I'm guessing it's high because of the transformer
heya that is a nice power ogg grid solar inveter but I'a still connected to the grid so I'm looking for a inverter that as the batteries are full I still can give back to the grid
i'd definitely be interested in the USB > PC functionality and the software.
I am currently using the LV5048 inverter and it works great but as in your previous test with that inverter I am running into the same issue with my miter saw. It switches over to grid automatically when I power on the miter saw. Not a huge deal. On the other hand the MPP solar software is pure garbage so I'd be interested in this aspect for this inverter.
Yes a comparison between the MPP software and this would be useful
Yes I've been talking with Franklin for a few months at Sigineer as they allow AC coupling and 240 split phase but they don't have the battery range I need but they seem really good and the price is right. Thanks for the video
Ive also been talking with Franklin for a few months. Going to buy the 15kva split phase inverter and another HF inverter possible the mpp LV5048 split phase for its pv charger and use it to power more sensitive loads while the LF inverter powers more heavier loads. Plus, the mpp inverter seems to have more exact charge options for my battery bank.
Any recommendations on 60v inverters? I’m interested in a 60v bank and 120v service. Thanks for the videos!
I don't know of any 60v inverters I'm really happy with. But there are several 48v inverters that go up past 60v I like. Several models go up to 64v which is good enough, but some go higher. The Magnum MSPAE will go up to 68v. That's sweet.
DavidPoz check out threads on anotherpower.com. The forum is a bit dead but there are some good reads. Some of the guys have built their own inverters and I’ve heard of 96v inverters.
@@billssolarpowerandgardenin1016 It is not a true inverter but I just got my hands on a APC SURTA3000XL UPS and it runs off of 16 12V 5ah SLA batterries which were dead of course. That means it takes 192V DC to make it run. I bought some 3.7 cells from Battery hookup w/ BMS and plan to try and revive it. It should be a 3Kw Pure Sine Wave when I get it running.
First thought was the noise. And I sure wouldn't want to Lug the thing around.
BUT... You can't hear it over the chop saw😲😁😏
And for a down and dirty unit it'll get the cabin built and a lot more. So actually it's a pretty good value. I'd buy one if I had a need.
Great review as always 👍
Hi David!
I am using 4 panels of 260 watts 30 volts 15amps (REC 260 Peak Energy Z-link series).
My Solar controller charger inverter is PowMr 60amps 3000 watts 48 volts with PV input of 145 volts.
Using 14s Nissan Leaf batteries with BMS 48 volts.
Should I do series of my 4 panels to make total of 120 volts or series 2 panels total 60 volts then do a Parallel for 4 panels?
Advice from will be really appreciated from you thank.
Gerry
More details the better! It allows us to decide if we want to buy one. I really like the MPPT from your friend. I will be building an offgrid system with 3 of those.
I'm considering the Sigineer 3,000 Watt, 24v inverter, charger, MPPT charge controller and the GroWatt with the same specs. Do you have any thoughts on quality and features of these units? I'm looking to use them on an RV with a 2kw panel array and may add a generator to the system. Or can you recommend other brands?
When you loaded the inverter down with the Vac and Miter, what was the load on the battery side? Is it possible that you reached the max amps capable on the wire or had too much voltage drop from the load and not the max load the inverter could handle? I didn't notice what size wire you used on the battery side to make sure you didn't overload it.
Assuming a 48VDC input and 3400W pull, that'd be 71A on the batteries/wires. This is an estimate and most likely a bit low because the digital meter wasn't updating fast enough to keep up with the constant changing power draws 10:35. You can hear the beep of the inverter for a second or two before the meter updated. So it's quite possible the amp load was much higher for that second or so.
The battery pack was at 57 volts, maybe 56.5v. The positive wire was #6, about 2.5 feet long. The negative wire was bigger, just stuff I had on hand.
Thanks for creatingsuch great videos 👍
Bit of a strange pop when you connected the batteries.. Id be interested to see the remote gen etc. I wasnt expecting it to start the saw tbh but it did well
Yes please. The more info, the better.
Thanks for all your work David.
Hi Dave - wondering how this product is doing. Thinking of making a purchase similar (24v). Used to think MPPT was the way to go - but after reading amazon reviews - I think I want to steer clear of them. Would love an update on this inverter/charger.
Would it be safer or even matter to hit the input with 24v then 48v?
Yes I would like to see the generator set up, great video.
For the buzzing/noise of the inverter, it's possible to quiet it down. Take the transformer out and make sure there's some rubber padding between it and the case. And have some hard rubber bushings at the screws. Might even need some rubber padding where the boards also come into contact with the case.
Also, make sure there isn't space between the covers and the chassis as this is another spot of possible noise generation. So again, a little bit of rubber padding (thin window weather seal perhaps) to make sure it can't vibrate against itself.
Thanks for the tips. I'll take a look.
awesome video man yeah get into the other part the USB and everything I would like to see it will do
Thanks for letting me know.
Great learning video for us uninitiated old folks!! Thanks for sharing & more parameter study would be invaluable as well.
Did you ever invest into creating a small DC grid in your house for DC devices? I'm wondering if it is more efficient when running DC devices from batteries with a DC-DC converter instead of going from battery DC -> AC -> back to DC. Would love to hear your thoughts and maybe create a small expiriment in the future.
I don't know enough about it to run appliances on DC. I'd be OK with running some 12v DC throughout to run LED's.
I have an mpp solar one and it does not get off utility when the sun comes up, and it waste a lot o energy. I had to turn the 800 watts pure sine wave inverter on mine. the mppt charge controller work really well but if you start using energy the fan is very loud.
Very nice unit .. The ac in will this unit automaticially swith to grid power if not enough battery or pv. Power ??
I have not tested that feature, but the manual says it can.
Thank you David for the Great review. How many ohms is the resistor that you use to precharge the capacitor?
That was a 2ohm, 100W resistor. amzn.to/3o39dsA But the exact ohms doesn't so much matter. I've used 1-10 and still work.
hi i want to ask you if i can run this inverter with lithium battry 18650 24v with bms and charge it in the internal mppt charger in the inverter thanks for help brother
No, this is 48v only.
@@DavidPozEnergy okay if i add 48v can it run
@@kamalelidrissi2629 Or purchase a 24 Volt inverter. But 24 Volts will reduce the max Watts output.. What is your 18650 configuration ... 7S100P ???
Hi David, love your videos. What did you do with those 8,000 watt Reliable inverters that you had?
I gave some away and sold one.
Glad you got something from that outfit, I got one similar turns out it was a 240v model still got it stuck with it still need one but I won’t buy from them.
I enjoyed this video alot, most of it in the miter saw part, that miter saw really its the toughest tool to proof any inverter really works!!😂😂
Another great video. Are these units able to be set up in parallel to increase the total output capacity?
No paralleling. If you need more capacity there are better solutions out there.
Another interesting video David. I'm interested in this feature: AC input with effective online synchronous stabilizing(AVR) technology
That noise on your oscilloscope is probably just the back EMF (electrical noise) pushed back into the wiring by the motor starting up.
You can try my theory by attaching the same setup to grid power.
Hi David...love the content...I was curious, if you had to pick an all-in-one unit which one would you suggest?
My friend, Ben, uses a Sol-Ark 12k. It's top of the line for all in one units. However, it comes at a premium in cost. I've tested MPP Solar LV5048 before and didn't like it. So If I was to pick one right now and didn't have the funds for a Sol-Ark, I'd buy a Phocos 5k. lddy.no/s5eo But I plan to test more of these all in ones during this year to get a better answer.
@@DavidPozEnergy Awesome thanks for the info… I’ll check them out
Yes get into it, would be nice to see, ty David
6kw battery pack is awesome
Great David. You made me laugh several times. Always like it when you pull out your power tools to test with. Nice video Keep them up. Waiting for the 2 inverters to get hooked up soon. Thanks
Hey and thanks for the video.
I got a question... so the machine is rated fo 48v battery and you battery is over 57v, i also notice you programe the charging controller to charge the battery up to 58v.
is best to use high capacity batteries?, if wanna set up a 24v system i can confortable use 36v batteries?.
Thanks.
When we say 48v inverter, or 48v battery, we are talking about the "nominal" voltage. All the equipment must be the same nominal voltage to work together. But the actual voltage will vary at any given moment in time. Voltages of the battery are constantly changing and the inverter has a range it can work with. I think this particular unit can work with a range of 42-64 volts. You will have to check the specifications of your particular unit and battery.
@@DavidPozEnergy So if the solar inverter have a range between 24v to 48v charging the 36v batteries will be fine?, i will double check everything.
Thanks.
Could you use several of these in a home that adds up to 10kW? Or would you just go with a larger inverter?
This model does not support pairing. You would need to go with a larger inverter.
I am curious to know if the unit is UL or ETL listed? I am always concerned when I see foreign language markings on most components.... I saw CE markings in the video...
Contact the mfr via their website ...
Great review!
What was the cause of the popping noise?
I don't like the automotive fuses in a inveterate.
Yes a bit noisy.
I asked Sigineer about the noise and they said it was capacitors.
I wonder what would happen if you put a super capacitor bank in your system to take the initial brunt of the power requirements. would be interesting to see.
Is there a way to set the eod and dod lower than the 34.5 and 39.5 preset settings?
Thanks in advance
Manny
I don't know. I gave this away, it's not worth getting.
Nice man. I’m looking at their 12Kw version. I was aghast at the buzzing sound when you turn it on. Is it really that loud? Planning on using it near a sleeping area and hope its not going to make that kind of buzzing when I’m trying to sleep!
I would NOT use this near my bed. It's the loudest inverter I have tested, similar noise level to a window AC I think. One of my cameras microphones was really picking it up. This inverter uses a cheaper transformer (E-style). There is another style out there called toroid, but is used in more expensive inverters. The toroid is much quieter.
DavidPoz Ack! Ok thanks for the great info. Ill ask about the different styles before I buy. For instance, I understand the 15Kw (singineer) inverter is much quieter.
Great video!!!!! Yes please dig in further
Thanks for letting me know.
Hi David, I enjoy your videos, very informative. Have a question about this inverter and the 8000 relaible, which one should I buy? I work with power tools like your saw, for home projects.
I would buy this one for temporary situations. Where you only need to power a tool once in a while, then it gets turned off. If you need the inverter running 24/7, then this one is not the right choice. Buy one that is more efficient, like Aims, Outback, Victron, Magnum.
I love that lg battery you built its bad ass
I love your obvious glee.
David have you thought of testing a flow battery with this inverter or the mpp inverter
Any special concerns for using aluminum bus bars instead of thick wires?
When using aluminum, you need to coat it to prevent oxidation. There are several brands on the market that sell electrical grease.
Want to convert my van so i can run a mig,tig or stick welder from an inverter. What would be the best inverter to use and also what would you say the best brand of inverters is regardless of cost ?
Regardless of cost I think Victron and SMA are tied in top.
Do you have a suggestion on the smallest wattage grid tied inverter? I'm hoping 150W?
Down that low you might be looking at "Micro inverters". I have some of the first enphase micro-inverters that are still running well. But I don't work with grid-tie inverters enough to suggest one brand over another.
@@DavidPozEnergy thanks David, I appreciate the feedback. I found a nice enphase thats about what I want, but was told 'used' could be a problem due to how they can be tied to networks. The model I was looking at can't be had new. Do you find the need for a central controller a problem with yours? Could you share which model you are using? Thank you!
My model is the 215 (I think) installed 8 years ago. I don't even use the central controller thing. I've never been on the "portal" because you need to give them your information. Mine just turn the meter backwards and that's good enough for me.
That is great demo.. Instead of pv input.. Can I use dc coming from my alternator 48 v?
Also can same applies on battery input? Replace with power source from. Dynamo 48 dc volt
The input DC voltage has to be higher than your pack voltage. I was charging about 58v, so I would need at least 68v or more coming in. I don't know if your alternator can do that or not. But the battery must be a battery.
I can ensure that about voltage from alternator is higher .. Coz before I was warned by suppliers not to use charge controller with any input dc... Just was surprised.. That why I did ask you
THIS IS ONE HEAVY DUTY LOW FREQUENCY INVERTER LIKE THE AIMS THAT CAN RUN LARGE LOADS AND HAS A PV CHARGER . BUT CAN 2 OF THEM BE HOOKED UP BY A DATA CABLE LINK LIKE THE MAGNASINE INVERTERS FOR 220 V ?
Nope. This unit does not parallel, sync, or anything like that.
shame it is not a 240v version as thats our power in the uk i do like these units i like how thay can run solar and flick over to a generator when needed or even hydro instead of solar what was the max ampage for solar
Then buy the model that has 240 Volts! Why is that so hard?
Think that equipment would run a hot tub that plugs into a regular outlet. Heater pump comes on about every 15 min. And a couple refrigerators?
If you can plug it into a normal 120v outlet, you can probably run it on this unit. Most outlets are 15 or 20 amps. At 120v that's up to 2400 watts. This inverter is 2500 watts,
This unit has an auto on-off feature based on load, that turns the inverter off automatically. This should help with the high idle draw
Hallo ich bin der Sascha aus Deutschland...
Und ich habe ne frage wo bekomme ich denn inverter.
Denn du hier vorgestellt hast .lg sascha
Holy crap, that would have to be set up in in the neighbors garage. That buzzing would drive me to the ,,,,, Shinning . And my name isn't JOHNNY
The stacks with the metal fins are rectifiers.
@DavidPoz - I have a suggestion David. I have a heater that ramps up very slowly in power (like 1 to 2 minutes to go from 300W to 600W on the low setting but I will check to get it more exact), and is good for finding out a maximum power of an inverter by already getting it close to the rated maximum using loads you already have, and then firing up the "ramp up" heater and monitoring the total wattage. I will test out the heater again and send the make and model so maybe you can get one locally there and use it for testing (and actually as a heater too), or maybe I can just send you mine since I don't use heaters much here,
Thank you for the review of the inverter. Nice that it is a low frequency type and can handle large start up loads. The auto generator start up would be nice to see but not because I would be interested in buying this particular unit. That very loud transformer would keep me from purchasing it. I think the better brands use a round toroid transformer. Also the standby current seemed rather high. I would like to see how it compares to other Low frequency inverters.
What All in one inverter would you recommend for a rv with a 1,560 watt solar array? I am new to diy solar and I am addicted to your channel.
If your RV is only running 120v, then I'd suggest this one: lddy.no/s5eo If you are running 120/240v, then two of those, or you could do one Sol-Ark.
Hello mr. Poz!! It is that noise coming from the fan or its the internal components like transformer or any induction noise? Also want to say very good video and thanks for sharing your findings with Sigineer inverter cause I recently purchase one and hope to have it soon 👍🏼😎🇵🇷
The camera was really picking up on the transformer noise. It is louder than other inverters I've tested, but not as loud as tools or vacuum.
DavidPoz I understand that, microphones pick noise that we normally don’t hear loud because of the induction or magnetism, as of i saw in the video the inverter is tough working above the parameters or at least neart to the maximum capacities
looks like a nice inverter! the only thin I dislike is the idle draw is to high, but the surge is amazing and I do like this company I have the 6000w and its working really well now. if your using this to just run tools i would buy it.
Hello brother.. Ilike your video.
I'm looking into doing a chest freezer powered by solar panels also but idk where to start help plz?
I did a video on that. Check it out and if you have more questions after, let me know. ua-cam.com/video/V7gCcc9x-eU/v-deo.html
That label on the transformer at 4:21 is wrong since no transformer can convert 48VDC to anything other than heat. I know it is probably just an identifier for the whole unit.
There's another board that converts the 48Volt DC to 48volt AC then it goes to the transformer
but yep you are correct in what you mean though
The biggest problem seems to be the limited voltage on solar panel input. Followed by stand by consumption, efficiency and noise. It’s not that unusual for a hybrid inverter to be inefficient compared to a grid tied solar inverter.
Well done video. You should really speak more about the bloody awful huge 123W no-load draw for only a 2500W inverter. No load draws are a good measure of the quality of a inverter and by that measure this is a terrible one. Wouldnt own one if you gave it to me.
In example my Samlex 2224 has a no load draw of ~30W - and even though it costs almost twice as much as a Sigineer its still cheaper than having to add the extra panels and battery capacity to support that constant extra daily 2.9KWH load. And a better quality inverter will last longer.
Good morning David there is not a single video that I miss, I have all seen them I try to imitate you in my house in some things that you do you are my source of inspiration, everything you do is excellent, I live in Colombia and it is not easy to get at a good price everything you teach I have a small 24v solar system and I have bought 48v lithium batteries I am needing that inverter to start the pair of 48v batteries that I buy there will be some way to buy it and send it to my country Could you help me?

@@DavidPozEnergy Good evening, friend, David. Thank you to answer me so quickly, if in Colombia we use 120v at 60hrz in general and 220v in a few appliances such as air conditioners, but my consumption is at 110v-120v throughout my house, I would like to have that inverter inform me how I could acquire it. in the best possible way since I tried and they only ship to the United States and not to Colombia
Excellent video.... 👍😎🖖...
Please more detail review...

Great review David !
Thanks Mark.
Is low frequency good? Efficiency? Idle power consumption? Sine wave inverter, good! It's a bit loud. 👍Thumbs up and subscribed!
Generally speaking HF (high frequency) inverters are more efficient than LF (low frequency) inverters. HF is also cheaper to buy. But LF is better at handling surges, such as air conditioners and tools.
Can you please explain the advantages and disadvantages of low frequency and high frequency invertrers?
Both can produce pure sine wave, 120v AC. So both can be used. It depends what you plug in. If you only use things like heaters, TV's, lights, computers, then you can use a HF. But some things need the LF (transformer based) to start the big surges like AC, compressor, Saws. HF is smaller, lighter, cheaper. LF is bigger, heavier, more expensive. These are generalizations I'm making. The industry is moving to HF for everything as the computers get better and faster to react. Like the very expensive Sol-Ark is HF, but listed to have a very respectable surge.

Dave, is it possible to pair two of these together to get higher AC voltage to your AC power system?
Nope, they do not pair or sync. Just stand alone.
I actually have been looking at there inverter chargers. Any way to get them to send you one of those
@DavidPoz - Hey Dave. Seems like a nice unit. It will pay for itself when you cancel your gym membership. What is the maximum charge current rating on it for a 48V battery bank? How many amps is it rated at (assuming you have enough PV power coming in to cover it)?
Specs say max 65 amps charging, or 3500 watts of solar PV. That's a lot more than I tested it with, but I didn't want to build a whole combiner box to parallel more strings.
@DavidPoz - That unit might be a good size for me for when I retire overseas because I need to ship it in a box of size 24x18x18 inches so it would fit nicely in there even double boxed. I already have powerful 110V to 220V voltage converters that should work well with something like this Sigineer combo product. Luckily where I am going overseas, they also use 60 Hz AC, just 220V instead of 120, so my voltage converters will be very handy (they can do both 110 to 220 and 220 to 110 (both ways). i sent some there already to my fiancee and she said they are working well (I sent her some 120V stuff from USA).
Let you know if you need any replacement parts under warranty from this company you will have to pay a very high shipping cost. My remote went out for my 6000w inverter and just for replacing it was $70 in shipping. Great inverter but very expensive warranty if anything goes wrong.
I've always wondered why you'd not opted for an inexpensive soft start module long ago. I've previously commented as such. This would solve the high in-rush current issues with your power tools.
As for this inverter/charger, the parasitic consumption, while totally understandable, is too high for my off-grid applications. The hum from the transformer (also understandable) is crazy loud, as well!
Lastly, I'm philosophically opposed to the single point of failure that combination devices represent. While they can admittedly take up less space and simplify wiring, I'm just more comfortable with discreet devices performing better overall due to device optimization, and less of a concern to cut corners on design and/or cost.
It's been my experience that any device performing multiple functions usually does so at some cost somewhere. Coupled with the old adage that "you get what you pay for", the performance and total cost of ownership usually disappoint over the time.
Anyway, that's my 2¢. Be well.
Hi John, I agree with you. This is not my go-to for most situations. We are both fans of SMA and it is a totally different league. I do, however, think there is a place for everything. I think this would be great for a tool truck, or tool trailer with a few panels on the roof and the occasional use at jobsites that don't offer grid power.
@@DavidPozEnergy Thanks for your reponse, David. I actually design, build and support portable worksite power systems from single-phase 120V/split-phase 240V, to three-phase 208V/230V. Total capacity varies based on load, quantity and duration requirements.
For value-based systems, I typically employ soft starters. For larger systems, I parallel inverters such as PIP models from MPP Solar. With these, I can parallel up to nine units in single-phase configurations. Up to six units are supposed for three-phase configurations (48Vdc input only).
The largest systems run a multi-unit condenser and multiple commercial and residential air handlers in custom-designed trailers used in mobile marketing by a major inverter A/C manufacturer.
Nearly new Tesla packs, charged via solar or mains power, supply inverters powering various single- and three-phase 230V loads. Multiple inverters provide ample current, while Variable Frequency Drives perform phase conversion for the condenser.
I was able to supply two trailers for the price of one of their previous truck-based platform that required shore power. The trailers can go anywhere and require no set-up as they're 100% off-grid.
