Background:
My system is off-grid w/grid-assist. I'm in my 5th year of PV (13kw) -> Midnite Classics -> 48v battery (121kwh) -> AIMS Inverters ( 2 x 12,000w) -> House circuits via ATSs (grid assist).
After 4 years (25,000hrs of operation) one of the AIMS started putting out voltage drops or spikes (not sure) above 5% load causing my APC UPSs and ATSs to switch every 10sec over and over. So I pulled it from service. First contacted AIMS support in Dec 2022 and there are no replacement boards available for the foreseeable future.
I need a replacement and I no longer have faith spending $ on brand-name for future support so I'm committed to going cheaper for the 8,000w - 12,000w replacement range such as SUNGOLDPOWER ( https://www.amazon.com/dp/B0B5VS2Y67 ) rather than Victron or Schneider. I also want a single unit instead of parallel setups such as EG4 or MPP Solar.
Question:
There's going cheaper such as SUNGOLDPOWER which makes a reasonably priced ETL 12,000w model but then there's going way cheaper as in this https://www.ebay.com/itm/125394217937 type of approach
I understand that at most it's 8000w continuous and that I'll need to sort of load test it to verify it's not overheating etc...
I understand that it's not likely to run more than a few years compared to 10yrs? for top tier or even 4 years for AIMS....
But assuming I approach this carefully with increasing load tests / monitoring and it will actually sustain 8000w level will it be any riskier than
- my AIMS going haywire causing havoc on my loads?
- hurting home appliances due to noisy sine wave (or something)?
- catching fire compared to AIMS or SUNGOLDPOWER?
I'm asking for comment on risk or warnings to stay away in comparison to a SUNGOLDPOWER 12,000w 240v/120v or AIMS 12,000w 240v/120v baseline.
