Questions about this product

What is the EG4 WallMount Indoor 14.3 kWh battery?

A 51.2 V, 280 Ah LiFePO4 wall-mount battery with LCD, integrated self-heating, dual fire arrestors, and 600 A internal busbars. Rated for over 8,000 cycles at 80% DoD, 10-year warranty, UL 1973 and UL 9540A.

What are the charge and discharge limits?

Max continuous charge and discharge are 140 A. EG4 recommends 60–140 A in normal use. The BMS trips around 200 A, so design wiring and protection accordingly.

What is the operating temperature range?

Charge 0 to 50°C. Discharge −20 to 55°C. Storage 0 to 45°C. Indoor rating is IP20.

Does it support closed-loop communication with my inverter?

Yes. Selectable CAN or RS485 with EG4 inverters and options for Schneider, Sol-Ark, Victron, Growatt, Megarevo, Luxpower, and Deye. Protocols are set from the battery’s LCD.

How many can I parallel and do I need external busbars?

Using the built-in 600 A busbars, up to 3 batteries with one inverter, 4 with two inverters, or 5 with three inverters. Larger systems require external busbars and fusing sized at 200 A per battery. Do not series connect these batteries.

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.

ON-BOARD LCD TOUCH SCREEN
Easy to see BMS monitoring, and selectable closed-loop communications with EG4, Schneider, Sol-Ark, Victron, Growatt, Megarevo, Luxpower, and Deye inverters.

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

INTEGRATED SELF-HEATING FEATURE
Internal heating keeps cells operating during cold temperatures.

INTEGRATED BUSBARS
The battery design comes manufactured 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 up directly to the connection ports of EG4 inverters allowing a sleek and efficient installation. For other inverters or stand-alone battery installation, the conduit box plugs should be installed.
