    • Great value for money, works as expected.
Size: 12V-4000W
I am used to expensive marine grade inverters that produce a real pure sine wave. So i was not expecting a huge amount from these, as the price is 1/10th of the units i am used to. The units i am used to have been working away 24/7 for over 20 years with no issues, a tough act to follow. I got 3 of these for a house project, all 3 arrived properly packed. I unpacked and tested all 3, they all worked perfectly, no issues. Setup is easy, as would be expected, the hardwire connections are not really industrial grade, but they are adequate (barely). The remote is nice, easy to read in daylight or night. The battery percentage is not calibrated for LiFePo4 batteries, so do not use it to give you an accurate SOC status. But in truth you should never use the inverter to give you that data, you must get it from the battery itself, as the inverter will measure line voltage including the drop due to its own load. Use a Victron battery monitor or similar. I ramped up testing on each unit, from light loads to full bore, in incremental steps. Up to about 1200w it produces 120VAC from 1200 to 3800w it produces a clean and steady 118VAC 60hz. I have seen reviews where there were complaints that the voltage dropped below 110VAC on medium to high loads. My units worked as expected, but you must use suitable DC cables to power the unit. I tossed the DC cables that were provided in the box, they were worthless. I used properly made short run 2/0 AWG marine cables to power them, If the run was longer (>6ft) i would use 4/0 cables instead. The fan is fairly noisy, only has 2 speeds on and off. A variable speed fan would be a much better solution and would have added about 10 cents to the build cost. The fan came on around 1500w for my tests, but it would depend on the ambient temp for each case. As i planned to have these in a separate equipment room, the fan noise is not an issue. There is a slight delay ramping up the output power, but nothing i tested (heaters, induction cooktops, hair drier, tools, etc) complained or failed to work correctly. The delay you see on is just in the display updates, rather than the power itself. I put an oscilloscope on one of the output ports when it was producing 3000w of power, the sine wave is still clean. As someone else mentioned there is a tiny amount of top wave clipping, but the waveform is sufficiently clean to power everything i tested. I do not plan on using these for computers etc, for that i installed a Xantrex Prosine2.0, cost far more than all 3 of these, but i know they are totally clean waveforms. The waveform on these inverters is actually better than the Honda EU2000/EU2200/EU3000 generators. I cannot speak to the longevity of these inverters. If i find failures or issues down the road, i will update this review accordingly. So far i am very happy with them. ... show more

This inverter surprise me with the performance I can run my washer and dryer at the same time and the TV and a fan all day as long as there is sun very impressed at first I thought it was something wrong with my inverter but because the TV wouldn’t start, I guess I rushed to unplug it because it wouldn’t turn on right away. I got scared but it works fine. I was gonna return it, but I canceled it. I recommend this inverter very highly. ... show more

    • Great Inverter
Size: 12V-4000W
I have been using this inverter for a few weeks now 24/7 with no problems or issues. The only thing that keeps me from giving it a 5 rating is when I checked the output with an oscilloscope, it wasn't quite a perfect sine wave, it had a tiny bit of square wave at peak, not enough to be a problem or even be noticed by the ordinary user, it's just an observation. ... show more

    • Make sure you have at least a 300 amp breaker on the DC side coming in to the inverter

It works perfect. I hardwired it into my trailer and it works fantastic. Had a little trouble with the first unit I got, but I had no trouble returning it and getting a new one.
