The most common faults on REFUSOL inverters

On many REFUSol inverters, errors appear that relate to the incorrect operation of your inverter.
Try switching off the grid breaker and switching it back on after 2-3 minutes.
If the problem persists, you will need to send us the inverter for repair.
You can call us on +30 2310 607032 for any related information.
