Cheap Inverter - Looking for deeper understanding of operational pitfalls

I'm 100% certain in any shortage, priority goes to backordered sales over replacements/support.

Well - I now have 2 x 175lb bricks. The good news is the inverter box, fans, and huge toroid transformers are likely OK, so if I can't get replacement boards I may very well try one of these hooked up to the big transformers. Not a lot to loose.

Update.....

SGP (SunGoldPower) support finally got me replacement boards - took 5 weeks overall. I got them last Friday and was able to fix the inverter! One brick is now working, one to go. They messed up and sent a control board without wifi but otherwise it works fine and I don't care about wifi. So I'd give them a thumbs up because I now have a fixed inverter.

AIMS support never did send boards, and stopped communicating with me about it. I may have found a board repair place... e.g. they test / replace individual components on the board. This is in progress and I may be able to get the AIMS fixed as well - but still a few weeks out.

Shame about AIMS.

Deleting this since my issues with aims wasnt quite the same.

Success story - AIMS 12,000w Control Board Repair

Wanted to share an inverter control board repair "success story" in case like me, you have a failure and the company won't sell you replacement parts. At the beginning of 2023, one of my AIMS 12,000w inverters failed. After 25,000hrs (~5 yrs) of operation the 240v/120v output became erratic...
