The intelligent information age greatly increases electricity demand, which, in return, pressures people into seeking for green power generation due to the severe environmental pollution and energy consumption. Solar PV power generation is expected to alleviate the pressure. With government’s policy support and less cost of power generation, energy storage systems are brought in tens of thousands of households. For the entire household energy storage system, MORNSUN provides a complete power solution to simplify customer’s design and increase system’s reliability.

Residential Energy Storage Systems is the core energy storage device of the system and needs to be monitored online status in real time, so the importance of BMS is self-evident. In the BMS management system, BCU real-time communicates with CAN bus and BMU to get monomer voltages, cabinet temperature, insulation resistance and others current sensor to collect charge and discharge current and dynamic calculation SOC touch screen to display relevant data The BCU calculates and analyzes all the information of the battery pack and then intelligently manages the system, communicating with the independent CAN bus and achieving the secondary protection of charge and discharge through a relay. The latter ensures an effective isolation for strong electricity and weak electricity, meets customer’s demand for diverse security control and guarantees a stable and efficient operation of the system.
