why am I seeing draw from batteries with no load connected?

Hello all,

Yesterday I started using my MPPT 100/50 with my BMV 712 monitor. I have disconnected all my loads from the battery but I am still seeing current and watts being drawn from the battery on the BMV, when the charge controller is activated. Im I missing something or reading things wrong?


Many Thanks

battery

Can you give us some pictures of the system and/or screenshots of VictronConnect?

I don't see anything wrong.
You currently get about 200W from you MPPT into the batteries.

Connect VictronConnect to the MPPT and you will see nearly the same voltage, current and power.

Turn off the upper switch from the PV-panels and the current/power should drop to nearly zero.

its a little confusing as all the readings are in the output tab. Also, the charge controller is reading about 7a of current where as you can see the BMV is reading a much higher current. Is that normal?
