Right now I read: BMS Battery Voltage:54.00 V , BMS SOC 87%. Probably 100% would be not so "Full"... Will check. Edit: from the Deye Cloud records: BMS charging voltage: 58.4 V Battery voltage during charging : 60% 54.2V 50A 80% 54.5V 48A 90% 54.6V 47A 97% 55.0V 47A 99% 54.6V 24A 99% 53.7V 0A During all charges maximum voltage at 99% was 56.3V; At 100% it stay at 53.9 - 53.4 V. Info in the Battery manual: Nominal Voltage (V) 51.2 Operating Voltage(V) 43.2~57.6
Yes, from solar. The battery is LiFePO4 Deye 4*5,1 kWh. I use only 30% of battery over night, so I thought it would be wise to keep the SOC at 35-80 % range. Right now I have limited charging power to 20A, but this solution is not good for cloudy days.
