Why You'll Love The EG4 WallMount 314Ah Indoor Battery
-
16kWh of backup you can count on. Store enough energy to carry your essentials — fridge, lights, Wi-Fi, and more — through an outage, so your family stays comfortable while the rest of the street waits in the dark.
-
Built to last 10,000 cycles. Rated for 10,000 cycles at 80% depth of discharge and backed by a 10-year warranty, it's made to be charged and drained every single day for years. Buy it once and stop thinking about it.
-
Smart self-heating for real winters. A built-in heater kicks in as temperatures near freezing, so the battery charges safely and keeps performing even in a cold garage or utility room.
-
Truly plug-and-play. Auto-configuration and closed-loop RS485/CAN communication mean it recognizes your EG4 inverter and sets itself up — no DIP switches, no guesswork, no headaches.
Your life, with the EG4 WallMount 314Ah Indoor Battery
Picture a storm knocking out power up and down your street. Porch lights dark. Fridges humming down to silence. Except yours.
Inside your home, the lights stay on, the coffee still brews, and the phones keep charging — because your EG4 WallMount 314Ah Indoor Battery took over the moment the grid dropped. No noise, no fumes, no dashing outside to wrestle a generator in the rain.
That's the quiet confidence of having your own power on the wall. On sunny days your panels fill it back up, so the energy you make at noon is waiting for you at midnight — and far less of your money goes to the utility.
It's genuinely smart on the inside, too. The integrated BMS actively balances every cell, updates its own firmware over the air, and lets you check on everything from the EG4 monitoring app. It cools by silent natural convection, so there are no fans humming in the background — you'll forget it's even there.
Safety is handled from the cell up. Stable lithium iron phosphate chemistry, internal fire arrestors, and UL 1973 and UL 9540A testing mean you can rest easy with it in your home. And when you're ready for more, add units in parallel and grow your storage over time. This is what real energy security feels like — quiet, dependable, and completely yours.
The EG4 WallMount 314Ah Indoor Battery in a nutshell:
-

-
Built-in self-heating — safe charging and steady output even when temperatures drop toward freezing.
