Sofar batteries belong to the manufacturer's advanced BTS E5–E20 DS5 energy storage series, featuring 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's 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-scale commercial energy storage systems.

Thanks to their IP65 rating and compact design, the modules can be installed indoors or outdoors, and the integrated BMS (Battery Management System) ensures safe operation of the cells. Sofar batteries are designed for 6000+ charging cycles, providing stable and reliable performance over the long term. Easy installation, high efficiency, and hybrid compatibility – these are the hallmarks of Sofar energy storage systems.
