Sofar batteries are part of the manufacturer’s advanced BTS E5–E20 DS5 energy storage series, which are built with lithium iron phosphate (LiFePO₄) cell technology and modular expandability. A single unit has a capacity of 5 kWh, and up to four modules can be connected in parallel, increasing the system capacity to 20 kWh. Sofar batteries are fully compatible with the manufacturer’s HYD and ME hybrid inverters, making them an ideal choice for residential and small commercial energy storage systems.

Thanks to the IP65 protected, compact design, the modules can be installed indoors and outdoors, and the built-in BMS (Battery Management System) ensures the safe operation of the cells. Sofar batteries are designed for 6000+ charge cycles, thus ensuring stable and reliable performance in the long term. Easy installation, high efficiency and hybrid compatibility — these are the characteristics of Sofar energy storage systems.
