Our 12/2000/80 Multiplus had been working fine until ~5 days ago. Now only the alarm LED light is on, we have no 120V AC at the outlets but still have 220V on shore power. The BMV 800 is reading 12.6V and our SOC is down to 59%. The last full charge state was 5 days ago, the day we disconnected from shore power in preparation for hurricane Isaias landfall. Returned next day to reconnect shorepower and no charger/inverter.
