RE: Calling all electrical engineers! Help me proof this listing for this power equipment - What do I need to know?
I would get in contact with the KEI solar manufacturer and see if they could give you some ideas based on the issues. Otherwise the agm batteries alone are most of the value. I would include what voltage and how many Ah (amp hours) the batteries are rated in your listing. Since they have a few years of duty cycling they won't sell like they are brand new. Sometimes those inverters have internal protection that saves them if there is any kind of surge. It would help to look up the technical specifications/users guide on the inverters. It may have a troubleshooting guide that can point you to what that code means it's outputting. If you can prove those inverters are in working order you can get more money for the system. I guess I would unplug the outputs to those inverters and test them individually outside of the system. Just plug a small device into each one. Those are a few things I'd suggest without being able to bring a multimeter out and doing some checks. Are y'all in Costa Rica?

Thank you! The website printed on the equipment was unused, but I searched 'KEI solar manufacturer' and I did find a company by that name. Can't believe I didn't think of that before....
Some testing was done on the inverters...but I'll talk to my friend and see if I can't get more information.
This is in middle Florida, near the gulf coast.
Yeah @ecoinstant I'd hope that company can help y'all troubleshoot their product especially since it's only a few years in service. Any system should be able to handle surges without catostrophic failure. I showed this to my buddy that is an electrical technician whom lives off-grid with his own solar power system and he said he recognizes those inverters as some that may be of poor quality control from China.
