Sigineer Power Off-Grid Solar Inverter 2500 W with MPPT Charger

Review of a transformer based hybrid inverter. Made by Sigineer Power. This is a 2500 watt inverter with a MPPT Solar Charge Controller. It's an all in one unit making building an off grid system super simple. This is also a 48 volt DC battery based system. Output: 120 volts AC.
I'm excited for this transformer based inverter because it can handle large surges. Making it perfect for tools and compressors.
This is not the most efficient inverter on the market, but it's a great price for being an all-in one unit. Retail price is $529 as of this video. Shipping to the US is $150 USD. www.sigineer.c...
I set up this inverter with a 6kwh battery I built in a previous video. If you would like to build a similar battery, then check out Battery Hookup. You can use my coupon code for 10% off. code: DAVIDPOZ

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.

[@DavidPozEnergy]

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.

[@ValleyMustang]

Yeah David what this guy said 👍

[@danielwilson2109]

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

[@Madsci-zy8wm]

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.

[@evertking1]

So you would recommend one over a EG4 6000xp

[@GapRecordingsNamibia]

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!

[@DavidPozEnergy]

Thanks. That makes me feel a little better about my Scope setup.

[@av1204]

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.

[@aaronberger1853]

~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.

[@keyronruddock9770]

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

[@Bennyboy-dog]

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.

[@andycanfixit]

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.

[@1981dasimpson]

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

[@GapRecordingsNamibia]

@@Bennyboy-dog 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...

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.

[@fredstephens6793]

I have the the Signeer 6KW 120/240 split phase unit and it doesn't have the noise problem that this unit exhibits.

[@korishan]

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.

[@DavidPozEnergy]

Thanks for the tips. I'll take a look.

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.

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.

[@jimthvac100]

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.

[@korishan]

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.

[@DavidPozEnergy]

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.

@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,

[@DavidPozEnergy]

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.

[@musicinspire1745]

@@DavidPozEnergy High frequency units are also more prone to failure due to demand because they lack the large transformer, and therefore the robustness of higher current handling. The components on those heat sinks in the high frequency unit you were not sure about are either power transistors, or power FET's/MOSFET's. Manufacturers are always looking to cut corners in their designs, and the consumer takes it on the chin when manufacturers over-rate the power capabilities of their end products. Bigger numbers, bigger price, even though you're not really getting what they advertise. As an Electrical Engineer, I see this happening all over the market.

Yes I would I’m very interested in that unit I have the same value due to getting my equipment to run and about ready to make a decision

[@a2cryss]

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.

[@BenCos2018]

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

[@mikeriverajr4447]

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$

[@mahirfredericks4013]

the stall current of the miter saw is really high, but i mean... if you stall on grid ac... it would pop the breaker...

[@lnxpro]

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.

[@SiriusSolar]

Yes a comparison between the MPP software and this would be useful

[@ManuelRodriguez-pk2mo]

Is there a way to set the eod and dod lower than the 34.5 and 39.5 preset settings? Thanks in advance Manny

[@DavidPozEnergy]

I don't know. I gave this away, it's not worth getting.

[@jancoow]

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.

[@DavidPozEnergy]

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.

[@nonlocalitykat]

Another great video. Are these units able to be set up in parallel to increase the total output capacity?

[@DavidPozEnergy]

No paralleling. If you need more capacity there are better solutions out there.

[@chrissteene]

David thanks for the video and info

[@danielleal298]

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.

[@DavidPozEnergy]

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.

[@dandil]

a stalled motor is close to a short so as long as the blade is spinning while cutting it should truck through.

[@1981dasimpson]

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

[@MrSummitville]

Then buy the model that has 240 Volts! Why is that so hard?

[@greggsatlauttamus9743]

Good tests! Good review! Exactly hit the real world problems and tests! I was sold after the cuts. Great product ! Tell them thanks again for making it ! It’d be nice if it wasn’t so loud. How about a hot water heater, a normal microwave oven, or a freezer / real full size refrigerator tests? Thanks!

[@DavidPozEnergy]

This particular unit is 120v only. So it will work with some water heaters, but not 240v models. Yes, a microwave is OK.

[@percybrown9191]

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.

[@lanfordmims5080]

David have you thought of testing a flow battery with this inverter or the mpp inverter

[@saschajodicke2946]

Hallo ich bin der Sascha aus Deutschland... Und ich habe ne frage wo bekomme ich denn inverter. Denn du hier vorgestellt hast .lg sascha

[@PhillipCarswell]

Could you use several of these in a home that adds up to 10kW? Or would you just go with a larger inverter?

[@DavidPozEnergy]

This model does not support pairing. You would need to go with a larger inverter.

[@fgllc]

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...

[@MrSummitville]

Contact the mfr via their website ...

[@Solar1Lab]

I love your videos!

[@paulbarrette2557]

Please do the rest of the tests

[@mondotv4216]

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.

[@nomad5454]

I'm looking into doing a chest freezer powered by solar panels also but idk where to start help plz?

[@DavidPozEnergy]

I did a video on that. Check it out and if you have more questions after, let me know. kzbin.info/www/bejne/jGjKdJaZbt1gm7c

[@tomb375]

Super Awesome! Just learning but I would love to hear your thoughts on a way to use the Solar panels and a inverter in such a setup for my Hot Tub. It has a 4.5 HP motor and heater. I'm here on Long Island NY and the Electric Prices are Killer and have to keep the tub turned down most of the time. Thank you so much for your video's I just subscribed!

[@DavidPozEnergy]

Sounds like you are running 240v AC. This inverter is 120v only. For over a year I used an Aims brand that was 120/240v. www.aimscorp.net/6000-watt-pure-sine-power-inverter-charger-48-volt-dc-to-120-240-volt-ac.html At the moment I'm running my house with SMA

[@tomb375]

@@DavidPozEnergy Thank you, yes it's 240v AC

[@MrSummitville]

@@tomb375 How much do you pay per kWhr of electricity? Typically, Off-Grid electricity ( Solar Panel + Inverter/Charger + Battery Bank ) is way more EXPENSIVE than Grid Power. You need to do some MATH first ! Also, Sigineer does make a 240 Volt AC Inverter/Charger. You are going to need, at least, a 4,000 WATT Inverter just to "run" the motor. You need to worry about the Starting / Surge amps, too. Is there an electric heater, also?

[@johncoinas]

I actually have been looking at there inverter chargers. Any way to get them to send you one of those

[@markanthonybumanglag1040]

Hello brother.. Ilike your video.

[@caroman6761]

Can you please explain the advantages and disadvantages of low frequency and high frequency invertrers?

[@DavidPozEnergy]

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.

[@ramzeneger]

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..
