Deye SE-F12-C – 11.8 kWh low voltage (LV) LiFePO₄ battery

The Deye SE-F12-C is a 11.8 kWh low voltage energy storage battery designed for residential and small commercial solar systems. Modern LiFePO₄ cell technology, modular expandability, and intelligent BMS monitoring ensure stable, long-term energy storage for Deye hybrid inverters and other compatible 48 V systems.

11.8 kWh energy storage for residential systems

The SE-F12-C battery has a nominal capacity of 11.8 kWh at a nominal voltage of 51.2 V. The 230 Ah capacity allows the system to store sufficient energy from daytime solar production and then use it in the evening or at night to power the household.

The battery supports up to 32 units connected in parallel, making it easy to create larger energy storage systems if consumption increases or the solar system expands.

Connecting parallel batteries – Victron Energy Lynx Power In busbar (M10)

If at least two low-voltage batteries are installed in parallel, proper DC distribution and bonding is required. The Victron Energy Lynx Power In busbar (M10) allows for the safe parallel connection of multiple batteries and provides a stable and organized DC distribution point for the entire energy storage system.

LiFePO₄ battery technology – safety and long life

The SE-F12-C uses lithium iron phosphate (LiFePO₄) cells, which provide outstanding safety and stable operation in energy storage systems. The cell technology is resistant to overheating and offers a long cycle life.

The battery can achieve more than 6,000 charge-discharge cycles under proper operating conditions, ensuring long-term reliable operation in solar energy storage systems.

Intelligent BMS and system monitoring

The built-in battery management system (BMS) continuously monitors the voltage, current, and temperature of the cells to ensure optimal charging and discharging. The advanced BMS protects the battery from overcurrent, overheating, or overcharging.

The system supports CAN and RS485 communication and can also be monitored from a mobile app via Bluetooth.

Flexible installation and easy expansion

The modules can be installed in a stacked, wall-mounted or floor-standing configuration. The battery is designed for indoor installation, making it an ideal choice for energy storage systems installed in garages or other protected, enclosed spaces.

Auto-networking simplifies system expansion, making it quick and easy to add new battery modules.
