RefuSOL 8k-23k

The classic with many years of experience.

  • Future-proof
  • Decentralized
  • Adaptable

The new generation is based on the successful platform, which stands for highest yields and freedom from maintenance. Whether you are integrating storage, integrating the PV system into Smart Grid networks or changing regulations – our constantly updated firmware equips you for the future.


Flexible design, worldwide compatibility

Plan and build your decentralized PV project to your own taste. Our devices can be used in various configurations and can be easily scaled for large plants. Faster return on invest is assured by subsystems that are already connected to the grid during the construction phase.
Our 08-23K string inverters are installed worldwide and are compatible to all major grid requirements. They can be used for voltage levels from 220 V to 460 V. We have also have a special UL series product line that complies to all the unique and specific requirements of the North American market.
