Deye SE-F12

A 12.03 kWh low-voltage LiFePO4 battery from Deye's SE line, delivering 10.83 kWh of usable energy per cycle and scaling to 384.96 kWh in parallel.

Models Covered: DEYE-SE-F12

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: Size your storage around real evening loads instead of stretching a small pack: the Deye SE-F12 fits 12.03 kWh into a single 51.2 V LiFePO4 unit, with 10.83 kWh usable at the recommended 90% depth of discharge. Continuous charge and discharge reach 230 A, and a 280 A ten-second peak covers motor start-ups, so the 3.5 kW rated DC output feels unconstrained in daily use. When the household grows, the bank grows with it: up to 32 units in parallel, and as many as 64 with a CAN-Bridge, for a ceiling of 384.96 kWh. The cells are rated for more than 6,000 cycles to 70% end-of-life capacity, with 37 MWh of energy throughput. Wall, floor or stack mounting, a 400 x 599 x 233 mm footprint and 84 kg of weight keep installation flexible, while CAN2.0, RS485, Bluetooth and app connectivity handle inverter pairing and monitoring. The published warranty term is 10 years.

Key Features & Technical Highlights

  • Deep usable capacity: 12.03 kWh nominal with 10.83 kWh usable at the recommended 90% depth of discharge.
  • High-current surge handling: 230 A continuous charge and discharge, with a 280 A discharge peak held for 10 seconds behind a 3.5 kW rated DC output.
  • Built for long service: LiFePO4 cells rated beyond 6,000 cycles to 70% end-of-life capacity, with 37 MWh of energy throughput.
  • Grows to 384.96 kWh: Up to 32 units run in parallel, and as many as 64 with a CAN-Bridge.
  • Connected and monitored: CAN2.0 and RS485 talk to the inverter while Bluetooth and the app keep owners informed; an LED display and buzzer report status.
  • Flexible mounting options: Wall, floor or stack installation in a 400 x 599 x 233 mm, 84 kg enclosure.

Frequently Asked Questions

Which inverters can the SE-F12 work with?

It is a 51.2 V nominal battery with a 44.8-57.6 V operating window, so it belongs with low-voltage hybrid inverters; it communicates over CAN2.0 and RS485.

How far can I expand a bank of SE-F12 units?

Up to 32 batteries connect in parallel, and the datasheet allows up to 64 with a CAN-Bridge, giving a maximum system capacity of 384.96 kWh.

What warranty does the SE-F12 carry?

Deye publishes a 10-year warranty term for this model, alongside a cycle-life rating above 6,000 cycles to 70% capacity and 37 MWh of energy throughput.

Where can the SE-F12 be installed?

It supports wall, floor and stack mounting; with an IP21 enclosure it should be placed in a protected location, at altitudes below 3,000 m and 0-95% humidity.

What temperatures does the SE-F12 tolerate?

Charging is specified from 0 to 55 degrees Celsius and discharging from -20 to 55 degrees Celsius, with storage recommended between 0 and 35 degrees Celsius.
