Deye SE-F12-L 12.03kWh LiFePO4 Battery – F Range

Deye SE-F12-L 12.03kWh LiFePO4 Battery – F Range

The Deye SE-F12-L 12.03kWh LiFePO4 Battery – F Range is a 51.2V low-voltage energy-storage battery developed for modern solar, backup and energy-management systems. With 12.03kWh of nominal LiFePO4 storage, an advanced battery management system and flexible installation options, it provides a strong foundation for homes and small businesses seeking greater energy independence.

High-capacity 12.03kWh module with up to 230A continuous charge and discharge capability. The battery can store surplus solar generation for evening use, reduce reliance on grid power and support compatible inverter backup circuits during outages. Final runtime depends on the connected load, configured reserve, battery condition and inverter efficiency.

High-performance LiFePO4 energy storage

LiFePO4 chemistry combines thermal stability, long service life and dependable daily cycling. The SE-F12 provides 12.03kWh nominal energy, 235Ah capacity and a nominal voltage of 51.2V. Its 44.8V to 57.6V operating range suits compatible 48V-class low-voltage inverter systems.

Deye recommends a 90% depth of discharge for this model. The official brochure specifies at least 6,000 cycles at 25°C ±2°C to 70% end-of-life capacity, subject to the manufacturer’s operating and warranty conditions.

Strong charge and discharge capability

The battery has a recommended charge current of 115A and a maximum continuous charge current of 230A continuous. Its recommended discharge current is 115A, with a maximum continuous discharge current of 230A continuous and a peak discharge capability of 280A for 10 seconds.

These electrical limits allow a correctly designed system to support demanding essential loads while maintaining controlled battery operation. Actual current may be reduced by the BMS according to temperature, state of charge and other protection conditions.

Advanced BMS protection and monitoring

An integrated Deye battery management system monitors the battery and provides protection for safe, stable operation. The F Range includes an active fuse design, local battery monitoring and automatic networking features intended to simplify commissioning and maintenance.

Communication options include CAN 2.0, RS485, Bluetooth and app access. Correct CAN or RS485 communication with an approved inverter allows the battery and inverter to exchange operating data and manage charge or discharge limits intelligently.

Scalable storage for future requirements

Up to 32 battery units can be connected in parallel according to the standard design, with up to 64 units possible when using the specified CAN-Bridge solution. This modular approach allows the storage bank to grow when future energy requirements increase, subject to professional system design, matching firmware and Deye’s installation requirements.

The SE-F12 also supports optional wheels, providing additional flexibility where a suitable floor-mounted arrangement is required.

Flexible installation

The battery supports wall-mounted, floor-mounted and stacked installation. The enclosure is rated IP21 and should be installed in a dry, protected and ventilated indoor environment. Operating temperature is 0°C to +55°C while charging and -20°C to +55°C while discharging. The specified maximum altitude is 3,000m and maximum relative humidity is 95% non-condensing.

Warranty and energy throughput

Deye lists a 5-year / 10-year warranty period for this model, with the applicable term depending on the final installation site and full warranty policy. The stated warranty energy throughput is 37MWh, subject to warranty conditions. Product registration, approved installation, compatible equipment, firmware and operating conditions may affect warranty coverage.

Compatible system requirements

This battery must be paired with a compatible 48V low-voltage inverter using the correct communication cable, battery profile and firmware. Compatibility should be confirmed before purchase, particularly when adding the battery to an existing battery bank. Mixing battery models, capacities, ages or firmware versions may require technical approval or firmware updates.

What is included?

This product includes one Deye SE-F12 battery in the requested L configuration. An inverter, solar panels, battery cables, communication accessories, mounting hardware, switchgear, installation and compliance work are not included unless specifically stated in the quotation.

Frequently asked questions

Can this battery work with any 48V inverter?

No. The inverter must support the battery’s voltage, current and communication protocol. Confirm compatibility and firmware requirements before installation.

Can additional batteries be added later?

Yes. The F Range supports parallel expansion, but all batteries and system components must comply with Deye’s design, firmware and commissioning requirements.

How long will the battery provide backup?

Runtime depends on the usable stored energy, connected load, state of charge, configured reserve and system losses. A load assessment is required for an accurate estimate.

Can the battery be installed outdoors?

This model is rated IP21 and should be installed in a suitable dry, protected and ventilated indoor location.

Does the battery include installation?

No. Installation, switchgear, cabling and compliance work are excluded unless specifically quoted.
