EG4 WallMount Indoor 48V 280Ah (14.3kWh) LiFePO4 Battery (2-6 Battery Bundles)

EG4 WallMount Indoor 48V 280Ah (14.3kWh) LiFePO4 Battery (2-6 Battery Bundles)

EG4-WallMount Indoor Battery | 48V 280Ah | 14.3kWh | Indoor | Heated UL1973, UL9540A | 10-Year Warranty

The WallMount Indoor 14.3kWh batteries are ideal for low-voltage residential indoor energy storage applications. The batteries use lithium iron phosphate cells with the highest safety performance and an intelligent Battery Management System (BMS) that can monitor and record the voltage of each cell along with the current, voltage, and temperature of the module in real-time. The BMS also contains a passive balance function and an advanced battery control method, both of which improve the performance of the battery pack.

Key Features:

  • Built-In 600A Busbars – Allows direct parallel connections with up to 4 positive and 4 negative terminals for simplified multi-battery setups.
  • Integrated Self-Heating – Keeps the battery warm in cold climates to ensure consistent charging and discharging performance.
  • Dual Fire Arrestors – Provides built-in protection against thermal runaway, enhancing overall system safety.
  • Emergency Stop Function – Enables instant system shutdown when paired with RSD-capable inverters or ESS disconnects.
  • Closed-Loop Inverter Communication – Seamlessly integrates with EG4, Sol-Ark, Victron, Growatt, Deye, Schneider, Luxpower, and Megarevo inverters for smarter energy management.
