Semookii LiFePO4 Battery Pack

Together with storage inverter, the system can realize the functions below:

Electricity Bills Reduction: Charge the battery during off-peak period and discharge the battery during peak period

Self-Consumption: Store excess energy generated by solar panels and use it whenever needed

Back-up Power Supply: Provide the power during grid blackouts.

Smart Energy Management: Real-time monitoring and managing. You can know how much energy generated and consumed in real-time.

● Lithium Iron Phosphate Cells
● Scalable Design
● Modular Design, Easy Installation
