Vevor 5000- watt budget Inverter for my Well Pumps.

I am trying out this new Vevor inverter to run my well pumps more efficiently. The inverter is a 5000-watt pure sign wave, and in this video, I am connecting the inverter to my house by way of the terminal box. It will be working as part of an off-grid system, so whenever the power goes off, the house will still have power. The inverter cost me under $500.

I bought a VEVOR 24v/3500W a couple of months ago. There are a few issues with it, 1) two of the outlets have hot and neutral inverted, two are right and two are backwards. 2) the cooling fan on my unit doesn't work properly, it makes a horrible buzzing sound when it tries to start at low speeds... and either doesn't spin or spins slowly and haltingly. Then it goes into overdrive and sounds like an airplane. Obviously a defective fan. I contacted VEVOR about this and they replied IT WAS NORMAL (anyone who has ever worked with cooling fans knows this is NOT normal) and 3) the terminal posts are M6 screws and are connected to the mainboard with 4x4mm2 wires, for a total of 16mm2 for each post. This is equivalent to 6 gauge wire, which is not enough for the amps this unit can pull from the battery bank. Overall it is a functional unit and these issues can be corrected, but VEVOR refused to help me with the fan, and that is a very bad sign from the company.

Thanks for the heads up. I have had my 5000 watt inverter for a little over a month now, and so far it is working fine. I will keep an eye on it. Thanks for your comment.

Not split-phase.

12v lots and lots of heat. You going to start melting things.

[@shoestringprep]

Nothing has gotten hot yet. Thanks for your comment.

@@shoestringprep seriously! When I was running 12v so much heat I even had three charge controllers, I upgrade to 48v one charge controller runs all the panels no heat and I use less than quarter the amps to run the same loads for longer time.
