REFUstore 50K/88K
The next generation of bidirectional high power battery inverters

 

  • Drastic reduction in BOS costs
  • Maximum power density
  • Easy serviceability
  • Suitable for 2nd Life Battery Application


The REFUstore 88K is based on the new inverter platform from REFU. It is applicable for different voltages. With a rated power of 88 kW at 400V, it is perfectly suited for commercial behind-the-meter applications such as self-consumption optimization or peak-shaving. With a min. DC voltage of 280V, the REFUstore 50K can be used in 2nd life battery applications.

Flexible integration, maximum freedom in planning

Thanks to AC-coupling, the REFUstore 88K can be easily integrated with existing PV systems. The highly modular solution allows it to be used in systems from 88 kW up to MWs in size to meet the demands of both energy and power applications.

This inverter is specifically designed for all high voltage batteries and, allows different communication protocols like Modbus RTU/TCP and Sunspec/
MESA. The higher flexibility in system design reduces BOS costs drastically.
