New requirements for existing plants
Three existing PV plants in Greece had to be retrofitted: the grid operator now required active power control and remote shutdown. The aim was to meet these requirements without interrupting the operation of the plants.
Retrofit with REFUlink
A REFUlink gateway was installed for each plant. It handles central power control and communication with the grid operator.
The existing REFUsol inverters remained in operation and are now integrated into modern monitoring and central control.
What the retrofit achieved
- New power control requirements met
- Existing inverters stay in use, with new communication interfaces
- Individual inverters can be replaced more easily, without reconfiguration
- Central monitoring of all plants via REFUview
“REFUlink turned a regulatory challenge into a simple modernisation of our plants – with minimal effort and high operational reliability.”
