What to do if my SAJ Suntrio Plus shows an AC Voltage Error?

  Donna HawkinsAug 16, 2025
  If your SAJ Inverter displays an AC Voltage Error, first check the connection between the inverter and the grid. Then, verify the on-grid standard settings of the inverter. If the grid voltage exceeds local regulations, contact your local grid workers to see if they can adjust the voltage at the feed point or change the regulated voltage value. If the grid voltage is within the regulated range and the error persists, contact your distributor or SAJ.
