About this battery
The EG4 3-Slot Battery Rack is the smaller sibling of the 6-slot cabinet. It holds up to three EG4 rackmount batteries in a server-rack format and works as a free-standing rack or wall-mounted bank for smaller off-grid and backup builds.
Three 100Ah batteries inside this rack lands at roughly 15kWh of usable storage at 48V, which covers a critical-load backup or a starter off-grid bank. Step up to the 6-slot cabinet if you're sizing for whole-home backup or a longer off-grid runtime.
Sold as the rack only. Pairs with EG4 rackmount lithium batteries like the LL-S and Lifepower4. Cable management runs inside the rack, with the inverter connection out the back or top.

EG4 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.
