Fronius Reserva 3.15 kWh single module

Make yourself independent and use your solar energy around the clock. The Fronius Reserva is a high-voltage battery with DC coupling that enables particularly efficient and low-loss energy transfer.

With flexible storage capacities from 6.3 to 15.8 kWh – depending on the number of modules (two to five) – it adapts ideally to your individual needs. Perfectly matched to Fronius hybrid inverters, it fits seamlessly into your photovoltaic system. Your data is optimally protected as it is stored exclusively on European servers.

The system can be expanded at a later date by adding additional battery modules.

Product benefits:

• Emergency power supply:
  The Fronius Reserva remains functional even in the event of a power failure and can restart independently. It reliably supplies you with energy, even in emergencies.
• Status display:
  Thanks to the integrated status display, you can see all the important information, such as the charge level or battery status, directly on the device at all times.
• Long-term performance guarantee:
  Fronius guarantees that the Reserva will still provide at least 80% of its original storage capacity after ten years.
• Slim and space-saving design:
  With its compact design and a robust temperature range of -20 to +55 °C, the Fronius Reserva even fits into tight spaces, such as garages, and enables flexible installation.
• High scalability:
  The modular Fronius Reserva storage systems can be stacked effortlessly – from 6.3 to 15.8 kWh per tower. For larger energy storage systems, you can connect up to four towers together to achieve a capacity of around 63 kWh – without any additional devices such as combiner boxes.
