Product Description
The Industry Standard for Scalable Energy Storage
The Balder Power 51.2V 100Ah Server Rack Battery is the workhorse of modern energy storage systems. Designed with a standard 19-inch rack-mount form factor, this 5.12kWh module offers the perfect balance of capacity, size, and flexibility for both residential solar and commercial telecom applications.
Build Your Power Bank, Your Way
Why be limited by fixed capacities? Our modular architecture allows you to start small and grow big. Connect multiple 100Ah modules in parallel to create a customized battery bank tailored to your specific energy needs—whether it’s a 10kWh home backup system or a 100kWh commercial power hub.
Safety & Intelligence Combined
Inside the rugged metal enclosure lies the heart of the system: premium A-Grade LiFePO4 prismatic cells managed by an intelligent Battery Management System (BMS). This ensures not only a lifespan of over 15 years but also real-time monitoring of voltage, current, and temperature. The front panel LCD (optional) and LED indicators give you instant status updates at a glance.
Universal Compatibility
Engineered for the global market, our 51.2V battery communicates effortlessly with most leading 48V hybrid inverters, making it a “plug-and-play” solution for installers worldwide.
