I've just hooked up the BMV-712 to my van's system that's been working well for months. I've got 2 LiPO4 Trillium batteries in parallel that solar charge with the Victron 100/30 Solar Charge Controller. I've also got a Battery-to-Battery Charger (Sterling 60amp) for cloudy days hooked into the system - its very plug-and-play. I've been using the Victron Connect app for a while and following the solar charging profiles. All has been going well and the 320 watts of solar keeps the batteries charged up very well (with minimal use over the winter). My question is: The BMV-712 measures about a +7 amp current (after I zeroed the current on the app) even when its dark. I have the Trillium batteries hooked up to the shunt's "battery" side. The other side of the shunt is wired to a negative bus bar that includes all negative loads in the system - including the starter battery (which I am using as my ground - the starter batter is then well grounded to the chassis). I am also monitoring the voltage of the starter battery with the BMV-712 via the +B2 input. If I was indeed drawing this much current into the Trillium house batteries for the last 3 months (from the starter) then my starter would be constantly discharged. This current is present when it's dark outside so its not the solar. Can you please help me figure this out?
