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 Netherlands that is ACM Netherlands. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
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.
