FE-HV-EC-A-5-2.9-14.5 | Complete Fox ECS2900 high-voltage battery stack with 1× master and 4× slave modules, providing 14.4kWh usable storage (from 5 × 2.88kWh LiFePO₄ modules) in a single modular tower.

System Composition

• 1 × Fox ECS2900 2.88kWh HV Battery (Master) V2.0, Connector Type A.
• 4 × Fox ECS2900 2.88kWh HV Battery (Slave) V2.0, Connector Type A.
• Total nominal capacity: 5 × 2.88kWh = 14.4kWh (≈ 12.96kWh at 90% DoD, sold as 14.4kWh “usable storage” bundle).

Key Features

• High-voltage LiFePO₄ battery stack for Fox ESS hybrid and AC‑coupled systems.
• Modular “Energy Cube” design – no external inter‑battery cabling, fast plug‑in installation.
• High usable capacity for whole‑home backup, time‑of‑use shifting and EV‑support loads.
• IP65 enclosure and wide operating temperature range for indoor or outdoor siting.
• CAN/RS485 communication with Fox ESS inverters for smart control and monitoring.
• Connector Type A (V2) ensuring compatibility across all modules in the stack.
