Server Rack Batteries
Scale your home energy storage with rack batteries. These rack-mount LiFePO4 units slot into a standard 19-inch rack for a clean, modular 24V or 48V battery bank.
Rack-Mount LiFePO4 Explained
A rack battery packages LiFePO4 cells, a BMS and terminals into a server-rack form factor. Multiple units stack and parallel together, so you can start small and add capacity as your off-grid or backup needs grow.
Voltage Options
24V
A 24v server rack battery suits smaller homes, cabins and mid-size inverters — a good step up from 12V with thinner, cheaper wiring.
48V
The standard for whole-home systems. 48V racks pair directly with hybrid solar inverters for the most efficient high-capacity storage.
Scaling & Parallel Wiring
Rack units connect in parallel to add amp-hours without raising voltage. As long as the BMS units are matched, you can grow a bank from 5kWh to 30kWh+ over time. Pair with our LiFePO4 boxes for smaller cells, or follow the home backup guide to plan the full system.
Frequently Asked Questions
How many rack batteries can I parallel?
Most BMS units support 4–16 modules in parallel. Check the spec sheet for your model.
Is 24V or 48V better?
48V is more efficient for whole-home power; 24V is fine for smaller cabins and RVs.
Do rack batteries work off-grid?
Yes — they're the backbone of most modern off-grid and solar backup systems.
