Hi all,
In my camper I connected the Victron BMV-712 to my battery system. The system consists of two batteries connected in parallel. Monitoring the current power consumption seemed to work well at first. A negative discharge current was displayed when switching on 12V consumers in the motorhome. However, when the inverter for the 230V sockets is switched on, the BMV displays a positive charging current.
How is it possible that a positive charge current is displayed when using the inverter and a negative discharge current when using the 12V installation?
Does this mean that the negative cable from the inverter does not pass through the shunt?
