Fox ECS HV ECM2900 Connector Type A, 11.52kWh 1x Master 3x Slave

Fox ECS HV ECM2900 Connector Type A, 11.52kWh 1x Master 3x Slave

FE-HV-EC-A-4-2.9-11.6 | Complete Fox ECS2900 high-voltage battery stack with 1× master and 3× slave modules, delivering 11.52kWh nominal (≈10.4kWh usable) storage in a compact modular tower.

System Composition

  • 1 × Fox ECS2900 2.88kWh HV Battery (Master) V2.0, Connector Type A.
  • 3 × Fox ECS2900 2.88kWh HV Battery (Slave) V2.0, Connector Type A.
  • Total nominal capacity: 4 × 2.88kWh = 11.52kWh.
  • Usable capacity at 90% DoD: ≈ 10.4kWh.

Key Features

  • High-voltage LiFePO₄ battery stack for Fox ESS hybrid and AC-coupled systems.
  • Modular, stackable “Energy Cube” design – no battery-to-battery cabling required.
  • 90% depth of discharge for excellent usable energy without compromising cycle life.
  • Wide operating temperature range and IP65 enclosure for indoor or outdoor installation.
  • CAN/RS485 communication with compatible Fox ESS inverters/chargers for control and monitoring.
  • Connector Type A (V2.0), ensuring compatibility within the stack and with matching inverters.
