Hello, I have recently experienced the following condition:
"Low battery" LED on (solid) and "mains" LED on (solid). No other lights were on, Inverter/charger NOT running. The batteries were showing at 75% SOC before and after this event. No history is recorded on VRM while the event lasted (~3 hrs).
Can you please tell me, is this some kind of a system fault (of what?), so we automatically switch to grid? What is the proper recovery steps?
I have Quattro 5000/48/70 and BMZ 7 batteries.
Thank you so much if you can spare some knowledge.
Peter
p.s. I know this topic exists, but circumstances are different, e.g. they have flashing led and/or charger/inverter on.
