Fronius Reserva Pro Battery

The BYD Battery-Box Premium HVM‑22.1 is a modular high-voltage storage system based on LFP technology, offering 22.08 kWh of usable energy and eight HVM modules connected in series. The system supports on‑grid applications, backup operation, and off‑grid scenarios, providing high efficiency thanks to true series connection. Compatibility with inverters from leading manufacturers enables flexible system configurations in commercial and private project environments. The stackable design with internal plug‑in connections reduces installation effort and simplifies later expansions.

• Warranty & SafetyThe protection unit ensures a high safety level for HV storage systems, as all battery and charging strings are protected on all poles. The integrated protective switches with tripping characteristic K respond both thermally and magnetically, ensuring reliable line protection in case of overload and short circuit. The user‑friendly switching technology simplifies maintenance and service without reducing operational safety. With a DC rated voltage of up to 1000 V, the design is intended to interrupt fault currents and potential hazards at an early stage, thereby reliably protecting system components.
  
  Safety‑relevant functions
  • All‑pole line protection to safeguard every battery and charging string.
  • Thermal‑magnetic tripping for precise disconnection behavior in case of fault currents.
