I'm converting a Ford Transit 250 into a camper and just finished setting up my electric system last week.
BMV 712 Smart Battery Monitor
MPPT 100v 30A Solar Charge Controller
(3) 100Ah LiFePO4 Battle Born batteries
Giandel 2200W Pure Sine Wave Inverter
Sterling 60A B2B Charger
Progressive Dynamics 60A 12v LiFEPO4 Battery Converter/Charger
I've been reading forums and doing a lot of research and can't figure out why the Battery Monitor state of charge just shows 2 dashes (--), and there's no history (Deepest discharge - 0Ah, Discharged Energy 0.0kWh, etc.). It's been this way for about a week now.
Also, when I turn my inverter on, it beeps continuously and says "Lo", indicating low voltage protection. Yet my 12v system runs and works fine (water pump, lights, fan, etc.). But when I turn the inverter on to use my GFCI outlets, they don't work. And again, I can't tell what my SOC is.
I've gone through the battery settings in the Victron app and changed everything to the recommended specs (see attachment).
Could anyone please point me in the right direction?
