A switch in the middle of planning

The solar park was already being planned when the decision was made to change inverter manufacturer: REFU instead of an international supplier. The deciding factors were the growing requirements of grid operators, the wish for full control over the plant and for a contact partner in Germany.

The system design was adapted at short notice. The project schedule was not delayed.

Commissioning with on-site support

A REFU service technician was on site for commissioning. He helped to put the plant communication into operation and made sure the plant was ready for operation straight away.

All parameters required by the grid operator and for certification were loaded and documented centrally via REFUlink and REFUview. The plant was successfully certified and has been running reliably ever since.

What the switch achieved

Redesign and implementation without delaying the project
Central parameter setting via REFUlink and support during certification
Technical support on site during commissioning
A dedicated contact, also directly reachable by phone
Full control over the plant: REFUlink and REFUview support operators in meeting NIS2 requirements

“The switch to REFU was implemented at short notice and without delay. We were particularly impressed by the direct availability and the reliable implementation of all regulatory requirements.”
