BMV 712 question. I have a new BMV 712 installed. It is new to the trailer, not replacing an existing BMV 700 in my 2022 Airstream that has 180w of solar. The BMV remains in place attached to a Victron Blue solar MPPT via a VE cable. When I am hooked up to shore power - 50 amp - the 712 shows my SOC and volts, but nothing else is changing like amps or watts. There is no history or trends. My installer told me there is nothing being displayed other than volts and SOC when on shore power. and the Volt readings match other volt systems so it appears to be hooked up properly from that perspective.
If you go off shore power, boondocking, as an example, the 712 will start working and show all the readouts on the 712. Is my system working the way it should or is the advice I received wrong and I have to start digging for the reason? and if the system is not working as designed, what do i need to do? Thanks in advance. I am a pretty basic mechanical guy with limited understanding of power.
