JFY - 5 Star Energy Error Codes

No any display in LCD or LEDCheck PV-input connections
W01 No gridCheck grid connection cables
W02 Vin over voltageCheck the Voc of PV string, see if it is greater than or too close to max. input. DC voltage of relative inverter type
E01 Isolation errorCheck the impedance is between PV(+) & PV (-) and the PV-inverter is earthed.
E02 Leak ErrorThe leakage current is too high. Unplug the inputs from the PV string and check the peripheral AC system.
E03 Grid FaultMake sure grid voltage and frequency meet the specifications.
