Your life, with the EG4 WallMount Indoor 100Ah Lithium Battery
Maybe you're not ready to run the whole house off-grid. You just want the peace of mind that the essentials stay on — the fridge, the router, a few lights — enough to ride out the next outage without a second thought.
That's exactly where the EG4 WallMount Indoor 100Ah Lithium Battery shines. Mount it on the wall, connect it to your inverter, and you've got 5.12kWh of clean power banked and ready, quietly waiting for the moment you need it.
Right on the front, a built-in LCD screen shows you what your battery is doing at a glance — charge level, status, and health, no app required. Inside, an intelligent BMS watches every cell, balancing and protecting them so the pack stays healthy for years.
And when your needs grow — a bigger fridge, a home office, an EV charger down the road — you don't start over. Add another unit in parallel and your storage grows right along with you. It's energy independence you can begin today and build on tomorrow.
Best of all, it's lithium iron phosphate at heart — the chemistry trusted for its safety and stability — wrapped in a UL1973 and UL9540A-certified design. That's reliable power you can happily live with, right inside your home.
