EG4 WallMount [Indoor] Lithium Battery | 14.3kWh | 48V 280Ah | Heated UL1973, UL9540A

The EG4 WallMount Indoor Lithium Battery is ideal for low-voltage residential outdoor energy storage system (ESS) 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 200A BMS
• Integrated 600A Busbars
• 82.6MWh Lifetime Production*
• 10-Year Warranty, >8000 Cycles @ 80% DOD

ON-BOARD LCD TOUCH SCREEN

Easy to see BMS monitoring, with selectable closed-loop communications compatible 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

Heats the battery when the ambient temperature is low to ensure reliable performance.

INTEGRATED BUSBARS

The battery comes with 600A internal busbars with multiple terminals (4 positive & 4 negative), eliminating the need for external busbars when paralleling batteries and/or multiple inverters.

INNOVATIVE EMERGENCY STOP FUNCTION

The optional ESS disconnect can shut down all batteries and inverters (if equipped with rapid shut down capability) with the press of a button.

THE PERFECT PARTNER TO EG4 INVERTERS

The optional conduit box mates directly to the connection ports of EG4 inverters for a sleek and efficient installation. For other inverters or stand-alone battery installations, the conduit box plugs should be installed.

The EG4 Indoor Buildable Conduit Box protects cables and connections between your battery and inverter. It is designed to pair the EG4 WallMount Indoor 280Ah Lithium Battery with EG4 18kPV, 12kPV, or 6000XP inverters, ensuring a versatile fit for your energy storage system. The unit includes side knockouts for battery-to-battery cable runs between paralleled batteries.
