Overall internal parts are high grade, its assembly is poor though. Better ones like this amzn.to/2LMbz9S by Power TechOn have modern all automated construction. I have installed numerous Power TechOn on solar jobs without any fails, but trying a new brand got me this PUGU inverter in the video. PowerTechOn is the same as a VertaMax product, at a lower cost.

China sells WHAT WE ASK FOR. They produce what corporations ask for. The cost cutting and Shortcuts are done on the side of the corporations. like Harbor freight or whomever… They go to China and specifically ask them to make them a cheaper product. They are at least two years ahead of the rest of the world when it comes to industrial equipment and electronics. Just like any country… They make junk and they make good stuff. And a lot of in between. Every country has their flaws, no country is without major problems. But after spending the better part of two decades importing and working with the Chinese… their products span all ranges of the quality spectrum. This coming from a blue blooded and proud Tennessean by the way. I enjoyed your two part series on these! Im still learning electronics troubleshooting. If I’m not woodworking… then I’m elbows deep in some weird industrial electronic device…prodding, poking, and PRAYING! Thanks again for the content!

Need help my 12 volts inverter have dc side and ac side mosfets so which mosfet is sutaitable for each side.

John what do you think about these inverters?WZRELB 5.0 out of 5 stars 5Reviews WZRELB Full Power Endurable 3500W 12VDC to 120VAC 60HZ US DUAL

Violence experienced during shipping whilst in poor packaging does not help. Zip ties for mechanical support? Not good.

Hello, 3000 watt solartronics full sinus inverter fault light is on. When the inverter is turned on, a relay tripping sound is heard, then the fault light is on, what do you think could be the problem?

I have power inverter that went bad, I suspect mosfets. Theres 4 of them IRFP260M. Do any other letters on it matter or not? I have P514J? Cant find exact mosfets, only IRFP260M part, other letters dont match. What else could be wrong with it if not mosfets. It powers on, shows voltage, says for a sec it uses 500w, then goes to 0. Cant power anything. I checked with multimeter the outlet, voltage is all over the place. No blown fuses. Maybe transistors? Nothing blown. Caps all good, connection to bluetooth shows all good. No alarms.

mine puts out 145 volts how do I get it down to 120-115

My powerbright 6kw 12kw msw inverter was showing 135.6v 32amp on all ports john so I unhooked it . Some kind of feedback transformer problem not sure. Do u fix these? I bet it's not a hard fix what would u charge me to fix it and test it? I can bring it to you to look at if you think u can fix this. The unit is out of warranty 600.00 unit. This has been a beast for 2 years always kicked ass. And the top positive terminal also broke and I would love to have fixed too. What can u do?

I think the main point that he’s trying to driveIs that they tossed safety out the window, with the wires touching that equals fire. Lower quality should not mean completely unsafe. It should mean cheaper parts or less features especially in something as fire hazardous as an inverter. Let alone I feel like the entire thing should be assembled.

Pay more get more..you get what you paid for..what kind of car sets in your and most of your neighborhoods laneways..Americans or Japanese.

Sad thanks for sharing . Hard to find American made most companies took that yearly trillion dollar tax break and ran to cheaper labor . mosfets made in China are bad very bad . Ellected should be protecting consumers in a perfect world .

why all the thumbs downs?

@ 1:13 "a raddling noise inside the inverder"? You need English lessons.

Ok shock me, don t think shocks are healthy, so not watching, have nice day shocker.

Yea, China makes a lot of junk. The Russians build stuff like tanks, not pretty though. around 30 years ago I bought a turntable that was made in Russia. That was one of the best turntables I've ever had, built like a tank and almost as heavy.

hey bro i loved your video i have an almost exact inverter here its from china garenteed piece of shit it has a problem i cant find its not giving errors but the relays aint allowing power output when its supose to run from batery ...its a tempest 3000watt they should have called it chinese cheap shit anyhow any schematics or pointers to the actual problem would help i replaced the relays and 2 hours later when the power failed in this shit country the relays again did not triger
