Application Places

For areas without urban power, the battery pack can be charged by solar panels, working with inverters, to provide 220V power supply for household use; for areas where urban power is expensive, the battery pack can be charged by solar power or city power during the day, and Electricity is supplied during times when electricity is expensive. The battery pack can also be used as a UPS to avoid information loss and emergency power supply caused by sudden power failure. Battery packs are suitable for commercial use, industrial and domestic power supply, agricultural power needs, and more.


Ultra-thin wall-mounted design, the bottom can bear weight, easy to install with a small crane. All screw holes are built in, the appearance is stylish and simple, and all wiring parts can be hidden in the bottom space. Using lithium iron phosphate BYD brand new original battery pack, the cycle life is up to 4000 times, and the life span is more than 12 years. Dust-proof structure design, DC output, safe and reliable. The BMS compartment is easy to replace. Integrated dangerous goods standard packaging, safe and convenient transportation.
