Hi, my BMV712 starts off from 100% when I start up the inverter (Multiplus Compact 1600VA) but then slowly drains to 0% and never rises above it again. The MPPT however gets to float nicely every day and stays there. I have a refridegarator connected to the inverter so it does go on every now and then but still the MPPT stays on float.
Dunno what’s wrong. My BMV settings are as follows.
