Product Overview
The 48V 200Ah rack mount LiFePO4 battery delivers 10.24kWh in a standard 19-inch rack enclosure. Designed for commercial energy storage, telecom backup, and larger residential systems, it supports parallel expansion for larger banks (e.g. 16 units = 163.84kWh where the BMS and inverter support that count; the maximum parallel count is confirmed per project).
- 10.24kWh per module — high density for commercial use
- 19-inch rack standard — 4U height, easy integration
- CAN/RS485 BMS — inverter communication ready
- Parallel expansion — scalable in 10.24kWh steps; maximum parallel count confirmed per BMS / inverter pairing
For smaller rack options see our 51.2V rack mount series. For wall-mount alternatives see 51.2V 200Ah wall-mounted.

Sizing a Rack Bank: From One Module to 160kWh-Class Banks
One 10.24kWh module already covers a large home’s overnight loads or a small commercial backup requirement. The rack format pays off when the bank grows — every added module is the same 4U unit, wired in parallel:
| Modules in parallel | Total energy | Typical project fit |
|---|---|---|
| 1 | 10.24kWh | Large residential storage; small office backup |
| 2 | 20.48kWh | Whole-home backup with solar; telecom site with extended autonomy |
| 4 | 40.96kWh | Small commercial solar storage; multi-tenant or farm loads |
| 8 | 81.92kWh | Commercial backup and peak-shaving projects |
| 16 | 163.84kWh | Larger commercial / industrial installations (16 × 10.24kWh = 163.84kWh; parallel count confirmed per project) |
Two sizing rules apply at every bank size. First, keep all modules in a bank identical — same model, same configuration. Second, check the bank’s combined continuous discharge (150A per module) against your inverter’s rating and surge; a bank sized only by kWh can still be undersized on current. Send us your inverter model and load profile and we will check both numbers before quoting.

Wholesale, OEM & ODM
Volume pricing for installers and distributors. Custom BMS protocols available. Contact us.
For distributors, this model is built to be a standing line item: a single standard SKU in the highest-demand capacity class, a documented parallel path your installers can sell as expansion, and OEM branding available when your volume justifies your own label. Reorders keep the same specification and communication configuration, so the modules your customers add next year match the bank they installed this year.
Frequently Asked Questions
The page says 48V — why is the nominal voltage 51.2V?
Because “48V” is the system class name, and 51.2V is the actual nominal voltage of a 16-cell LiFePO4 pack (16 × 3.2V). LiFePO4 batteries sold for 48V systems are almost universally 51.2V nominal. What matters is that your inverter supports the 51.2V LFP charge profile — send us the inverter model and we will confirm.
How many units can I parallel, and what do I get?
The maximum parallel count depends on the BMS and inverter pairing and is confirmed per project; as an example, 16 units would give 163.84kWh (16 × 10.24kWh). All units in a bank should be the same model and configuration.
Can the BMS talk to my inverter?
The BMS provides CAN, RS485 and RS232 interfaces. Protocol variants are matched to your inverter before production — this is a per-project confirmation, not an assumption. Our BMS selection guide explains what to check.
Is this the right module for a telecom base station?
It is designed for that use: 19-inch rack compatibility fits standard telecom cabinets, and parallel modules set the autonomy. Confirm the site’s load and required backup hours with us and we will size the module count.
