I have the 3kW Hybrid inverter, running at 24v, with 2 banks of LIFE 12v batteries, 24 each bank.
Hooked up to 12 250w 30v solar panels wired as 6 banks (60v) of 2 panels each.
Been running fine for over a year,generator as backup, which I run weekly just to check it works.
In the last year I've needed the generator only after 4 days of overcast.
Suddenly, today, I get a fault code 03 (no battery)
I measure the batteris, 2 banks, both at 26.5v.
I measure the voltage at the input to the inverter, 6.5v.
So? I turn everything off, PV first (both banks), battery second, inverter last.
The 6.5v reading gradually drops at the input terminals to the inverter.
Wait 2 hours, restart everything, same result.
So it seems I have a dead inverter, anyone have any suggestions?
