Download Datasheet Download Manual Download Certificate The Deye SE-F12 battery is a Low Voltage energy storage solution designed for residential photovoltaic systems and applications that require high storage capacity in a compact format. The model provides a nominal energy of 12.03 kWh, a capacity of 235 Ah and a nominal voltage of 51.2 V, using LiFePO4 technology, known for its thermal stability, high level of safety and long service life. High Capacity and High Performance The Deye SE-F12 is designed for Low Voltage systems with an operating voltage range of 44.8 V to 57.6 V. The battery can provide a maximum continuous charge/discharge current of up to 230 A, while for short-duration peak demand it can reach up to 280 A for 10 seconds. Actual operating current may vary depending on temperature and battery state of charge. Modular and Scalable System For installations requiring higher storage capacity, the Deye SE-F12 supports the parallel connection of up to 32 modules in the standard configuration. By using a CAN-Bridge, the system can be expanded to up to 64 batteries in parallel, allowing the storage capacity to be adapted to the energy requirements of the project. Smart Monitoring The battery features CAN 2.0, RS485 and Bluetooth communication and is compatible with the Deye application for local monitoring of operating parameters. The system includes LED indicators for state of charge, operation and protection status, as well as an audible buzzer warning. Long Service Life LiFePO4 technology and the intelligent Battery Management System contribute to a long operating life. Deye specifies at least 6,000 cycles for the SE-F12 under the manufacturer's defined test conditions and recommends a 90% Depth of Discharge (DoD). Flexible Installation The Deye SE-F12 can be installed: wall-mounted; floor-mounted; in a stackable configuration. The battery has an IP21 protection rating and is intended for installation in indoor areas protected from moisture and weather conditions. The charging temperature range is 0°C to +55°C, while discharging can take place between -20°C and +55°C. The dimensions of the current model are approximately 400 × 559 × 233 mm, with a weight of approximately 84 kg. Warranty and Certifications The product is listed by Deye with UN38.3, CE and CB certifications.
