EG4 AllWeather 14.3kWh Outdoor Battery — 280Ah (EG4-AW-WM-280AH)

The EG4 AllWeather 280Ah is the outdoor version of EG4's popular 14.3kWh wall-mount battery — purpose-built for installations where the battery needs to live outside, in an unheated space, or in environments that see harsh weather. With a NEMA 3R weatherproof enclosure and an operating range of −20°C to +60°C, this battery is genuinely built for Canadian winters.

If your electrical panel is in an outbuilding, your battery room is unheated, or you simply want the storage outside to free up indoor space, the AllWeather 280Ah delivers the same 14.3kWh of LiFePO4 storage as the indoor version — wrapped in a housing that handles frost, rain, snow, and heat without compromise.
