OV-G-V means the Grid voltage is higher than the protective value set in the inverter according to the local Grid standard.

1. Get the basic information:

     Model type,  serial number, error code,  how often the error happens,  software version,      installation & commissioning date,  Grid standard that is used inside of the inverter    currently.

2.  Other steps to be taken:


    2.1.    Check how often the error happens. 

              If only one or two times a day, then it’s caused by the unstable Grid;

    2.2.    Measure the Grid voltages at the AC connectors(wire side;

              (as showing in the picture below);

    2.3    Please check all the Grid voltages that are showing on the LCD of the inverter;

             (as showing in the picture below).

    2.4.    Check the Grid standard again, please make sure you are using the right one.

    2.5.    Please try to use the User def standard, please contact Solis for details and operation SOP;


3. Voltage can be calibrated on some model of the inverters.  Please call the service line and we can walk you through the process.
