July 25, 20224 yr My Deye Hybrid Inverter (new, 1 month in use) and JK BMS show different SOC values to each other. Do I need a communication cable between them? Some times with 100% SOC, indicated in the inverter display, the battery pack draws a large charging power abt 1.5kW. At the same time, the BMS shows the respective charging current with a SOC about 80%. Battery pack 230 Ah LiFePO4
July 27, 20224 yr Yes RS485/CanBus cable needed, the BMS should override the inverter's estimated value
