Rack-Mounted Battery 5kWh (51.2V/100Ah) - Rack-mounted series product image
The Rack-Mounted Battery 5kWh (model SCRA-R-51.2-100) brings the rack-mount platform to the 48V class with a 51.2V 100Ah LiFePO4 battery delivering 5120Wh in a 49.2 by 45 by 18 centimeter 19-inch chassis and a 100A discharge current. As 51.2V has become the de facto standard for modern residential and light-commercial hybrid inverters, this module is a natural choice for installers that prefer rack-mounted hardware over wall or floor-standing cabinets. It slides into any standard 19-inch rack, where it can be combined with inverter and distribution hardware in a single, tidy enclosure suitable for garage, plant room, or equipment closet deployment. The 100A discharge current supports continuous household loads, and the module can be paralleled to scale capacity up to 30kWh or more in a single cabinet. CMJ Solar's Grade A LiFePO4 cells provide 2000 to 4000 cycles with a 5-year warranty and CE, UN38.3, and MSDS certifications. For distributors building turnkey 48V storage racks for residential and small commercial customers, the SCRA-R-51.2-100 is a fundamental building block. CMJ Solar, based in Jiangmen, Guangdong, offers factory-direct wholesale and OEM services. Visit cmjsolar.com for details.

Frequently Asked Questions

What warranty does this product come with?

The Rack-Mounted Battery 5kWh (51.2V/100Ah) comes with a 5-year warranty covering the LiFePO4 battery cells and integrated BMS. Our LiFePO4 cells are rated for 2,000-4,000 charge-discharge cycles, providing 5-10 years of reliable daily use under normal operating conditions. Spare parts and technical support are available throughout the warranty period.

What is the MOQ (Minimum Order Quantity)?

The MOQ is typically 20 units per model for standard products. Sample orders of 1 unit are welcome for testing and evaluation. For OEM/ODM custom packaging or private labeling, the MOQ is 500 units. Contact our sales team for specific pricing based on your order volume.

How long can the Rack-Mounted Battery 5kWh (51.2V/100Ah) power my home during an outage?

The Rack-Mounted Battery 5kWh (51.2V/100Ah) provides 5,120Wh of stored energy (approximately 4,608Wh usable at 90% depth of discharge). At an average essential-load draw of 500W (lights, router, refrigerator, and TV), it can sustain power for approximately 9.2 hours. At 1,000W, runtime is approximately 4.6 hours. Actual runtime depends on total connected load and usage patterns.

Can rack-mounted batteries be connected in parallel?

Yes, multiple rack-mounted battery modules can be connected in parallel to increase total capacity. Each module operates at 51.2V with built-in BMS protection. The hardware (H) variant is a standalone module while the software (S) variant supports inverter communication. A standard 19-inch server rack or dedicated battery cabinet is required for installation.

How long does the LiFePO4 battery last?

The LiFePO4 cells in the Rack-Mounted Battery 5kWh (51.2V/100Ah) are rated for 2,000-4,000 charge-discharge cycles before capacity drops to 80% of the original rating. In a typical daily-cycle residential application, this translates to 5-10 years of service life. LiFePO4 chemistry also offers superior thermal stability and safety compared to lead-acid or NMC batteries, with no maintenance required.
