Questions about this product
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.
