Hi,
I have a strange behavior that I’m hoping someone might be able to help out with. The system is showing charging and SOC is going up when I have nothing charging. I have 8x100 BB batteries, Victron Quattro, MPPT, 2 CSLs for the batteries/Quattro and 4/0 cable everywhere. Battle born has confirmed that my “perfectly balanced “ wiring is correct, and my shunt is wired correct as well. My BMV and Quattro settings are correct too.
There are a few possibilities,
Please read through these previous cases, and see if they help you find the solution.
Please report back.

Definitely do a current calibration first.
Find a friend with a DC clamp ammeter and get a “second opinion” next, if that doesn’t fix it. If you see current at the shunt that way when you expect 0A, keep measuring until you find the culprit.
