Fox ESS EP11 10.36kWh 384V Battery with Heating Element
The Fox ESS EP11 10.36kWh 384V Battery with Heating Element (part no. FE-HV-EP11-H) is a high‑voltage LiFePO4 battery module with integrated self‑heating, designed for use with Fox ESS hybrid and AC‑coupled inverters to provide reliable, efficient storage in residential and small commercial systems, even in low‑temperature environments.
Key Features
- 10.36kWh high-voltage module – nominal 10.36kWh energy at 384V, providing a strong base capacity for grid‑tied and hybrid solar storage systems.
- Integrated heating element – built‑in self‑heating improves charge and discharge performance at low ambient temperatures and protects the battery when operating in colder climates.
- Scalable architecture – up to 4 EP11 units can be connected in parallel for a total storage capacity of approximately 41.4–41.6kWh, allowing future expansion as site demand grows.
- Long life and high efficiency – ≥4,000 cycle life at 90% depth of discharge and high round‑trip efficiency help maximise usable lifetime energy and return on investment.
- IP65 enclosure – floor or wall mountable IP65‑rated housing enables flexible installation locations, including indoor plant rooms and suitably sheltered outdoor spaces.
Technical Overview
- Part number: FE-HV-EP11-H (Fox ESS EP11 10.36kWh 384V Battery with Heating Element).
- Battery chemistry: Lithium Iron Phosphate (LiFePO4) prismatic cells with integrated BMS.
- Nominal energy: 10.36kWh; usable energy typically based on 90% depth of discharge.
- Nominal voltage: 384V, with an operating voltage range of approximately 348–438V.
- Round‑trip efficiency: typically ≥95%.
- Depth of discharge (DoD): 90%.
- Cycle life: ≥4,000 cycles under standard conditions.
Electrical Performance
- Max charge/discharge current: 27A continuous, suitable for high‑power operation with matched Fox ESS inverters.
- Peak discharge current: 65A for up to 60 seconds, allowing support for short‑term surge loads.
- Peak charge current: up to 32.4A for 5 seconds.
- Continuous power rating: around 10.3kW discharge and charge capability when configured within a compatible system.
- Communication interface: CAN‑based communication with Fox ESS inverters and system controllers.
Mechanical & Installation
- Mounting options: floor‑standing or wall‑mounted, enabling compact plant‑room layouts and space‑efficient installations.
- Ingress protection: IP65 enclosure for dust and water resistance in suitable indoor or sheltered outdoor environments.
- Dimensions (W × H × D): approximately 710mm × 625mm × 147mm.
- Weight: approximately 99–100kg per module, so appropriate fixing and manual‑handling provisions are required.
Operating Conditions & Compatibility
- Operating temperature: typical range 0°C to 55°C for charging and −10°C to 55°C for discharging, supported by the integrated heating element for low‑temperature operation.
- Installation environment: indoor or outdoor (sheltered) locations with 5–95% non‑condensing humidity and altitude up to around 2,000m.
- Compatible inverters: Fox ESS H1, KH, H3, H3‑Pro and US series high‑voltage inverter platforms.
