I have a BMV-712 and a SmartSolar MPPT 150/70. Today as I was watching the readings on the VictronConnect app, I noticed that with no load, the BMV was reading about 15 watts less going into the battery than the MPPT said. For instance the MPPT would say the solar is producing 467 watts, but the BMV would show 452 watts going into the battery. At ~13.5 vdc, that’s about 1 amp of discrepancy.
Is this normal? Is the MPPT consuming that power? Is the current sensitivity set too high on the BMV?
