All firmware for 3 Phase 5 KVA quattro , Venus and charge controllers , fronius are latest with BYD 10 KWH pro batteries - system VRM ID is TapetaMain
While troubleshooting my random switch offs I observed the following behaviour
The Battery sits steady at 55.5V and occasionally jumps to 55.6/55.7 volts at fill SOC Despite the Quattro settings of 55.0 as float and 55.2 as absorb
Both DVCC is on and the solar charge controllers show Remote control active .
has something changed in DVCC alhorithm ? I suspect my issues are linked to BYD switchiing off in Overvolatge when large load swings happend such washing machine or dryer happen .
