Battery Parallel Control Box
• The Battery Parallel Control Box is equipped with a built-in BMS (Battery ManagementSystem) main control module. The data from the parallel-connected battery modules is sent to the main control module for centralized control. It communicates with the inverter through the CAN (Controller Area Network) protocol.
• It supports a maximum of 8 parallel-connected battery modules, with the option to expandthe capacity up to 49.15kWh. It also features passive balancing functionality, ensuring that each battery module operates in the optimal state to achieve optimal performance.
• The Battery Parallel Control Box supports a maximum of 4 systems parallel connection,with a total capacity that can reach up to 196.6kWh.
LiFePO4 Battery Module
• The A-grade battery cells used in the Battery Parallel Control Box support 1C charge anddischarge rates. These lithium iron phosphate(LiFePO4) batteries have a cycle life of over 6000 cycles at 25 degrees Celsius and 0.5C discharge rate. They are known for their safety features, as they are non-flammable and non-explosive.
• The built-in BMS includes over 115 fault sensing functions, ensuring the safety andreliability of the battery system. Each individual module also has passive balancing functionality to ensure the consistent performance of the battery cells.
• The Battery Parallel Control Box is designed with a special structure that allows easy parallelconnection and communication between battery modules.
• It is designed to be both wall-mounted and stackable, providing flexibility in installation options.

In Scenario①:
The photovoltaic system, grid power, and battery are all functioning normally
A. In this scenario, the photovoltaic system is prioritized to supply electricity to household appliances. If there is any surplus energy, it will be used to charge the battery. However, if the battery is already fully charged or if the charging power exceeds the maximum limit, the ex cess energy will be fed back into the grid.
B. In this scenario, the photovoltaic system is again prioritized to supply electricity to household appliances. If the solar power generation is not sufficient to meet the power demand of the appliances, the battery will compensate for the shortfall by discharging its stored energy.
C. Once again, the photovoltaic system is given priority to supply electricity to household appliances. If both the solar power generation and battery discharge are still insufficient to meet the power demand, the remaining shortfall will be supplemented by drawing electricity from the grid.
In Scenario ②:
The photovoltaic system and battery are functioning normally, but there is a power out age or malfunction in the city's power grid
A. The photovoltaic system prioritizes supplying electricity to household appliances. If there is any surplus energy, it will be used to charge the battery. However, once the battery is fully charged, the photovoltaic system will limit its generation to only meet the power demand of the household appliances.
B. The photovoltaic system continues to prioriti ze supplying electricity to household appliances. If the power generated by the photovoltaic system is not sufficient to meet the power demand, the system will then draw power from the battery to supplement the shortfall and ensure a continuous power supply to the appliances.
In Scenario ③:
The battery has failed, but both the photovoltaic system and the city's power grid are functioning normally
A. The photovoltaic system prioritizes supplying electricity to household appliances, and any surplus energy will be integrated into the power grid.
B. The photovoltaic system prioritizes supplying electricity to household appliances. If the power generaled is insufficient, the system will supplement the shortfall by drawing electricity from the grid. ry to supplement the shortfall and ensure a continuous power
