  If your SAJ Inverter displays an AC Voltage Error, verify the grid voltage and the connection between the inverter and the grid. Also, check the inverter's on-grid standard settings. If the grid voltage exceeds local regulations, consult with local grid personnel about adjusting the voltage at the feed point or modifying the regulated voltage value. If the grid voltage is within the regulated range and the error persists, contact your distributor or SAJ.
