We do many auto genstart installations and have never used voltage as the autostart trigger. SOC syncs to 100% at the conclusion of every charge when absorption voltage is reached and charge current reduces to tail current level.
The SOC only goes out of sync if the charging parameters are incorrectly set.
A week ago I drained my battery pack down to zero. SOC showed an incorrect 20%.
My LIFePO4 cell went below 3V and that’s not particularly good. They do however survive all the way down to 2V.
Anyway, on this topic of “I was now able to configure my Volt autostart at the correct Voltage”. I think I got tricked by the fact that the “Start when battery…” value is set first (it’s on the top) and it can not be higher than the stop value. When i adjusted the stop value first, I could set it to the correct value,
Please do not be confused by my strange settings below. My pack consist of 7s LiFePo4 modules, and has therefore these low voltage settings - the Victron Equiment works btw fine with this “low voltage battery”
