EG4 Wall Mount Indoor Lithium Battery 280AH | 51.2V | EG4LIFPOW4WM-48V280A

The WallMount Indoor 280Ah batteries are specifically designed for indoor energy storage in low-voltage residential environments. These batteries use lithium iron phosphate cells, known for their exceptional safety features, and are equipped with an advanced Battery Management System (BMS). The BMS tracks and records real-time data, including the voltage of each cell, as well as the current, voltage, and temperature of the entire module. It also features a passive balancing function and sophisticated battery control methods to optimize the overall performance of the battery pack.

EG4 Wall Mount Indoor Lithium Battery Features

ON-BOARD LCD TOUCH SCREEN
Easily view BMS monitoring and choose closed-loop communications with EG4, Schneider, Sol-Ark, Victron, Growatt, Megarevo, Luxpower, and Deye inverters.

DUAL ON-BOARD FIRE ARRESTORS
Provide fail-safe protection against thermal runaway.

INTEGRATED SELF-HEATING FEATURE
Internal heating ensures the cells remain operational in cold conditions.

INTEGRATED BUSBARS
The battery is built with 600A internal busbars that feature multiple terminals (4 positive & 4 negative), eliminating the need for external busbars when connecting batteries or multiple inverters in parallel.

INNOVATIVE EMERGENCY STOP FUNCTION
The optional ESS disconnect allows you to shut down all batteries and inverters (if equipped with rapid shutdown) with the push of a button.

THE PERFECT PARTNER TO EG4 INVERTERS
The optional conduit box connects directly to the EG4 inverter ports for a clean and efficient installation. For other inverters or standalone battery setups, conduit box plugs must be installed.
