W02 Vin overvoltage error in JFY solar inverter

W02 Vin overvoltage error in JFY solar inverter

Solution

Check the Voc of PV string, see if it is greater than or too close to max. Input DC voltage of relative inverter type.

NOTE: During periods of little or no sunlight, the solar inverter may continuously start up and shut down. This is due to insufficient power generated to operate the control circuits, not trouble.

If you can not solve the trouble with the above procedures, Please contact Solarmatic or service personnel.

Before contacting the Solarmatic or service personnel, please find and keep at hand the following information:
