1. Get the basic information:

    Model,  serial number, error code,  how often the error happens,  installation & commissioning date;

2. Other steps to be taken:

    2.1.    Restart the inverter(turn off the DC side and the AC side for at least 5 minutes, then turn both of them on), if it will back to work normally, and not show up again, then solved.

    2.2.    Please check voltages between L1 & PE;  L2 & PE; L3 & PE; N & PE;

              If all of them are right, then move to the next step; ?

    2.3.    If not , please contact after-sales people of Solis.  And sent what you have got to them.
