SunSynk 16 kW charging higher voltage than requested from Hubble BMS v1.5
Sincs installation, my 16 kW SunSync inverter puts out a higher charging voltage, than what it reads from the Hubble Battery BMS. It reads the charging voltage required as 53.8 volts, BUT keeps on charging to well above 54.4 volts. this results in the cells going into overvoltage protection, until the complete battery pack also goes into overvoltage protection switch off. After the buitt in timer times out 1000 seconds, the battery shuts itself off, preventing discharging AND charging. This can only be cleared by toggling the battery switch OR clicking on the "charging" block in the PBMS program. The inverter definitely puts out a higher voltage that the BMS requires or requests. The PBMS Hubble BMS Parameter Settings is also on a picture. Unfortunately I could not take a photo when the charging voltage exceeded 54.3 volts, but THIS is what causes the disabling of the batteries.
The SunSynk inverter does not seem to stop charging at the required 53.8 volts, as can be seen on the photograph evidence. The orange "CHG Circuit" DISABLES DISCHARGING as well as CHARGING. Thus the battery "switch" is open, it then naturally takes very long to decay the voltage before the "overvoltage release" happens. ONLY MANUAL intervention can override this situation
