Compact Rack-Mount Design
The HOPE 5.0L-B1 features a space-saving 19-inch rack-mount design with a height of only 130.5 mm. This makes it easy to install in standard server racks or dedicated battery cabinets, saving valuable floor space in residential installations.
Excellent Peak Power Capability
With a peak discharge current of up to 250A for 150 ms, the HOPE 5.0L-B1 can reliably handle high inrush currents from appliances such as pumps, motors, or air conditioning units during backup operation — a significant advantage over many competing batteries in this capacity class.
High Scalability
The battery supports parallel connection of up to 48 modules. This gives installers great flexibility to build systems ranging from a single 5.12 kWh unit up to much larger residential or light commercial storage solutions.
Safety and Reliability
Built with premium LiFePO4 cells and equipped with an advanced BMS, the HOPE 5.0L-B1 provides comprehensive protection against overcharge, over-discharge, overcurrent, short circuit, and temperature extremes. The chemistry itself offers excellent thermal stability and long-term reliability.
FAQ
What is the usable capacity of the HOPE 5.0L-B1?
