Product Description
Maximize Your Energy Storage with the 14.3kWh Powerhouse
The Balder Power 51.2V 280Ah Server Rack Battery represents the next generation of lithium energy storage. Engineered for commercial and high-demand residential applications, this 14.3kWh module redefines energy density.
Why Upgrade to 280Ah?
Traditional setups require connecting multiple 100Ah batteries to achieve high capacity, leading to messy wiring and potential balance issues. Our 280Ah module solves this by packing 14.3kWh into a single unit. You can build a massive 229kWh system by paralleling just 16 units, saving valuable server rack space and installation labor time.
Industrial-Grade Reliability
At its core, we use A-Grade LiFePO4 prismatic cells—the same technology found in electric vehicles. Combined with our proprietary Smart BMS (Battery Management System), the battery is actively protected against overcharging, over-discharging, and temperature extremes. The built-in display provides real-time diagnostics, ensuring your system operates at peak efficiency.
Whether for solar self-consumption, peak shaving, or critical backup power, this battery delivers consistent, safe, and scalable power.

FAQ
-
Q: Can this 280Ah battery work with my existing 48V inverter?
A: Yes, our 51.2V nominal voltage is perfectly compatible with all 48V inverters. The Smart BMS supports protocols for brands like Victron, Deye, Growatt, SMA, and more. -
Q: What is the recommended charging current?
A: For optimal lifespan, we recommend a standard charge current of 140A (0.5C). The max continuous charge/discharge current is 200A. -
Q: How many modules can I fit in a standard cabinet?
A: Due to its high capacity, this module is slightly deeper than 100Ah units. Please check your cabinet depth (refer to the 700mm depth spec). Typically, a 42U rack can hold 8-10 units securely. -
Q: Does it come with warranty?
A: Yes, we provide a standard 5-year warranty with options to extend, backed by our technical support team.
