Deye Solar Batteries 12.03 kWh SE-F12

Q: What is the Deye SE-F12?

The Deye SE-F12 is a low-voltage LiFePO4 home storage battery holding 12.03 kWh at 51.2 V nominal and 235 Ah, of which 10.83 kWh is usable at the recommended 90% depth of discharge.

Q: How much power can the SE-F12 deliver?

It handles 230 A of continuous charge and discharge with a 280 A peak for 10 seconds, behind 3.5 kW of rated DC power. For daily cycling Deye recommends 115 A.

Q: Which inverters suit the SE-F12, and how many units can run together?

With 51.2 V nominal and a 44.8-57.6 V operating window it belongs on low-voltage hybrid inverters, communicating over CAN2.0 or RS485. One module works alone, 32 run in parallel, and up to 64 with a CAN-Bridge for 384.96 kWh.

The Deye SE-F12 is a 12.03 kWh, 51.2 V LiFePO4 battery with 10.83 kWh usable at 90% depth of discharge. One module is a complete system, and 32 in parallel reach 384.96 kWh.

Models Covered: DEYE-SE-F12

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: The Deye SE-F12 is a 12.03 kWh low-voltage LiFePO4 home battery rated at 51.2 V and 235 Ah, with 10.83 kWh usable at the recommended 90% depth of discharge. It sustains 230 A of continuous charge and discharge, peaks at 280 A for 10 seconds, and delivers 3.5 kW of rated DC power. One module is already a working system: the minimum module quantity is 1, and everyday cycling is gentler than the ceiling suggests, since 115 A is the recommended continuous current. The cells are rated beyond 6,000 cycles to 70% end-of-life capacity, with 37 MWh of energy throughput and a published 10-year warranty term. As demand grows, 32 units run in parallel, or up to 64 with a CAN-Bridge, for a 384.96 kWh ceiling. CAN2.0, RS485, Bluetooth and the app handle inverter pairing and monitoring, while LED indicators and a buzzer report state of charge and protection events. The IP21 enclosure measures 400 x 599 x 233 mm, weighs 84 kg and mounts on a wall, on the floor or stacked. We supply the SE-F12 as an authorised Deye distributor.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
