The battery is a 6.5kWh LiFePO4 pack. 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,
power conversion system (PCS), Grid, DC Breaker and loads in the residential energy storage system.
2.1 Application Scenarios
The four typical application scenarios are as shown below:
BAT
BAT
PCS
The energy produced by PV is optimized to supply
loads. The excess energy is used to charge battery,
then export to grid.
Battery powers loads at nighttime when there is no PV.
together with grid.

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. A maximum of 8 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 under temperature occurs.
• Protection:
Protect against over voltage, under voltage, over current, over temperature, under temperature, cell fault
and hardware failure.
• Report:
PCS

4
Report alarm messages and operation data to inverter via CAN network ports.
• Parallel connection:
Support a maximum of 8 batteries in parallel connection.
•
•
When battery does not connect to mains supply, hold POWER button for two seconds and battery powers
• Activation:
