EG4 WallMount 280Ah All Weather Battery — 14.3kWh, IP65
When winter throws its worst at your solar setup, this is the battery built to keep going. The EG4 WallMount 280Ah All Weather Battery — part of EG4's PowerPro line — mounts outside, heats itself in the cold, and banks 14.3kWh of clean backup power, so an outage or a cold snap never leaves you in the dark.
Your life, with the EG4 WallMount 280Ah All Weather Battery
You've seen what a bad winter storm can do — days without power, a freezer full of food you're hoping stays cold, and a scramble for anything that keeps the lights on. What if your home just kept running instead?
That's the promise of the EG4 WallMount 280Ah All Weather Battery. Mounted on an outside wall and wired to your inverter, it banks 14.3kWh of clean power and waits — and when the cold sets in, its built-in heater keeps the cells safe and ready, so freezing temperatures don't stop your backup.
Checking on it couldn't be simpler. The on-board LCD touch screen and SOC lights show you exactly where things stand — charge level, voltage, status — right there on the unit. Behind the display, an intelligent BMS watches every cell and flags a fault the moment it matters.
Installation is refreshingly painless, too. Weather-tight Degson quick-connects and heavy 600A busbars let you wire it up fast and parallel a few units on the internal busbars as your storage needs grow. Pair it with an EG4 inverter and the optional conduit box, and the whole system goes together clean.
Rain or shine, deep freeze or heat wave, it just keeps doing its job. That's backup power you can count on, season after season.
