It has a 48V battery module as the main power supply unit which composed of 32 64Ah cells in two parallel and sixteen serial connect (2P16S). Battery coordinates with PV, PCS, Grid and loads in the residential energy storage system. The four typical application scenarios are as shown below:FunctionCompared with normal batteries, the battery is characterized with better charging and discharging performance, longer cycle life and less self-discharging loss. The build-in BMS can monitor battery operation status and alarm timely to avoid operation out of limit. Two batteries can be parallel-connected to expand energy and power of energy storage system. Battery realizes communication with PCS via CAN network port.Monitoring: detect the voltage and temperature of cell, the voltage and current of battery.SOC estimate: indicate the precise volume of remaining electricity.Alarm: alarm when overvoltage, under voltage, overcurrent, over temperature or undertemperature occurs.Protection: protect against over voltage, under voltage, over current, over temperature,under temperature, cell fault and hardware failure.Report: report alarm messages and operation data to PCS via CAN and RS485 networkports.Parallel connection: support a maximum of two batteries in parallel connection.Power-off triggered by fault: battery powers off if level three under voltage, 0V cell orparallel connection failure happens.Forced power-off: when battery does not connect to mains supply, press POWER button fortwo seconds and battery powers off.Activation: input 45V~60V via P+/P- terminals, battery will be activated from off mode tostandby status.Technical ParametersNo.ItemSpecification1Nominal capacity/energy128Ah/6.5kWhRated/usable capacity/energy118Ah/6.0kWh2Typical voltage51.2 VOperating voltage48V ~57.6V3Standard charging current(25ºC)64AMax. discharging current(25ºC,3s)96AContinual Max. dischargingcurrent (25ºC)--85A85A4Rated discharging power3.3kWMax. discharging power4.4kWPeak discharging power5kW/3SRated charging power3.3 kWMax. charging power3.5 kW5Max.
