I recently install 3 x 4kw new BYD LVLs to an existing system on grid that had 3 x 4kw BYD LVLs so a total of 6 (two towers of 3) with a Victron Quattro 48/10000/140. I since I installed the 3 extra batteries my system as been slightly dropping SOC to 99.5% every 7 hours without any change in load or mains loss. What settings can I check to see why this is happening all of a sudden? Let me know if you need further screen shots of any parameters.
Update: I have fully bypassed the inverter so there are no loads and it still dropped SOC slightly on the 7 hour mark and went into bulk charge.
Update 2: did a discharge test all worked ok, went down to 20% SOC, charged back up to 100% and it went back to every 7Hrs issue again. At a loss.
