I can't get the "overload" light to clear. It's almost new. I was running it through an ELCI breaker to one outlet. The load was a 1500w electric kettle. This was temporary as I install the remainder the system. Now it has a red overload light on solid, not blinking and no other lights. No output at all. I've turned it off/on. I've disconnected from the ELCI. Then I disconnected the 6/3 AWG from the AC-1 output. So nothing but four 2/0 wires to feed DC input are connected to the Multiplus. Voltage at the inverter reading 13.2vdc
Anything else I can do or check?
