In general everything is working fine since 6 month.
But sometimes (feels like once in two weeks) the MP2 starts charging from grid with no reason at a low power rate.
Even if minimum soc is set to 0% (normally I have 10%) it suddenly starts charging when it is below 10%.
But most days it's not charging when it's below 10% and I can reach 5% with no charging or error.
Can anybody explain why this happens?
The battery SOC was 100% 2 days before.
It's a Multiplus 2 5000 with 2x Pylontech US3000C (same happens when it was 1x Pylontech months ago).
