Hi, we have 2x200amp hour Voltax LiFePo batteries wired in parallel for 12 volts to power our 4wd Canter camper truck habitat. We have an Enerdrive DC2DC e Power multi stage, multi source with MPPT charger, and a Victron BMV 712 Smart battery monitor.
The power sources are, the truck 24 volt alternator and 2 x 200 watt roof mounted solar panels.
Most mornings the Victron BMV app will tell me that the SOC is 88-92% I can check it again 10 minutes later and it will be showing 100% charged which i don't believe is possible. Can anyone help solving this issue?
