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.\u003c\/p\u003e\n\u003ch3\u003eYour life, with the EG4 WallMount 280Ah All Weather Battery\u003c\/h3\u003e\n\u003cp\u003eYou'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?\u003c\/p\u003e\n\u003cp\u003eThat'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.\u003c\/p\u003e\n\u003cp\u003eChecking 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.\u003c\/p\u003e\n\u003cp\u003eInstallation 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.\u003c\/p\u003e\n\u003cp\u003eRain or shine, deep freeze or heat wave, it just keeps doing its job.
