16kWh Indoor WallMount Battery (48V 314Ah)
16kWh of indoor lithium storage in a slim wall- or floor-mount enclosure. 314Ah of capacity, 200A continuous discharge, and built-in self-heating so it keeps working through a cold snap. Auto-ID lets you stack more batteries later without reconfiguring anything.

16kWh of storage that lives indoors.
The EG4 Indoor WallMount Battery is a 48V lithium battery built to sit inside the house, in a garage, a utility room, or a closet. It holds 16kWh and pushes 200A continuous, enough to carry heavy household loads when the grid drops. The enclosure is slim and IP20-rated, so it hangs on a wall or stands on its feet, whichever fits the space.
16kWh per battery
314Ah of LiFePO4 capacity in one unit. Enough to back up the essentials, and the start of a bigger bank if you need it.
200A continuous discharge
12.8kW peak output. It handles well pumps, AC startups, and other heavy loads without sagging.
Built-in self-heating
The battery warms its own cells in the cold so it charges and discharges reliably through winter.
Auto-ID stacking
Add more batteries and the system finds them on its own. No DIP switches, no address juggling.
Wall or floor mount
Hang it on the wall or set it on the leveling feet. Same battery, two ways to install it.
Third-gen BMS
Faster cell balancing, tighter monitoring, and the safety protections you want on an indoor lithium pack.
This is the battery we pair with EG4 hybrid and off-grid inverters on whole-home backup jobs where there is room to put the storage inside. It works for daily time-of-use cycling, solar self-consumption, and outage backup. If the battery has to live outdoors, look at the AllWeather WallMount instead.

Battery Cabinet 6 Slot
The EG4 6-Slot Battery Cabinet is the wall-mounted enclosure for stacking up to six EG4 rackmount batteries into a single bank. Each slot holds one 48V LiFePO4 server-rack-style battery, and the cabinet handles the cable runs, mounting points, and the side panels that keep the install looking clean. Six 100Ah batteries inside this cabinet builds out to roughly 30kWh of usable storage at 48V, which covers most whole-home backup or off-grid scenarios without needing a second cabinet. The arrangement keeps the comms and DC cabling inside the enclosure, with the inverter run out the top or bottom. Sold as the cabinet only. Batteries are sold separately. Pairs with EG4 rackmount lithium batteries like the LL-S and Lifepower4. Bolts to a wall stud and accepts batteries from the front.
