What to do if my LIVOLTEK Inverter shows an AC Freq Fault?

If the LIVOLTEK Inverter displays an 'AC Freq Fault', it means the grid frequency is outside the acceptable range. You should check the safety country setting, the frequency setting, and the connection of the AC cables. If the issue persists, contact your dealer for technical assistance.
