Basic Info.
Product Description
Operating Mode:
Ø When the photovoltaic is sufficient, charge the battery while supplying the load for use;
Ø When the photovoltaic is insufficient, the load is supplied by the battery. When the battery is insufficient, the EMS system starts the generator to charge the battery and continues to supply power to the load. The load power supply must not be interrupted;
Ø When the equipment fails, it can be switched to maintenance bypass work.
Zhejiang Bangzhao Electric Co., Ltd. Solar lithium battery energy storage hybrid system includes lithium iron phosphate battery module, BMS, solar controller, AC-DC charger,Pure sine wave inverter, central control unit CCU, temperature detector, integrated structure, etc.
The solar panels in this system are used for battery storage and power output;
The BMS module completes the detection and control of the voltage, current, temperature, SOC, SOH, and charging and discharging related parameters of the power battery pack;
The BMS system monitors the photovoltaic or solar cells according to the battery condition. The mains charging is controlled to maximize the protection of battery charging and discharging performance.
The sine wave inverter realizes DC to AC conversion to achieve DC conversion. Each detector is used to monitor the ambient temperature in real time to ensure the safety of the system. Centralized communication displays all the data of the system in an LCD touch screen.
