Meet the EG4 WallMount 314Ah AllWeather Battery — a high-capacity, outdoor-ready energy storage unit built for installs where space, weather, and long runtimes all matter. Delivering 16kWh at 51.2V, it’s designed to be a dependable backbone for solar-plus-storage, off-grid power, or whole-home backup setups that need serious capacity with straightforward expandability.

At the core are lithium iron phosphate (LiFePO₄) cells paired with EG4’s smart BMS for stable performance and long service life, plus active cell balancing to help keep the pack operating efficiently over time. The enclosure is purpose-built for exterior placements with an IP67 rating, and internal heaters support reliable operation when temperatures drop. For day-to-day ownership and long-term maintenance, Bluetooth + Wi-Fi connectivity enables live status checks and over-the-air firmware updates through the EG4 app—so the system stays current without hassle.
