JFY – 5 Star Energy Fault Codes

JFY - 5 Star Energy Error Codes

Display	Comments
No any display in LCD or LED	Check PV-input connections
W01 No grid	Check grid connection cables
W02 Vin over voltage	Check 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 error	Check the impedance is between PV(+) & PV (-) and the PV-inverter is earthed.
E02 Leak Error	The leakage current is too high. Unplug the inputs from the PV string and check the peripheral AC system.
E03 Grid Fault	Make sure grid voltage and frequency meet the specifications.

Display	Comments
Auto Test Failed	Auto test does not pass
W01 No grid	No utility, no grid connect
W02 Vin over voltage	PV panel voltage is too high
E01 Isolation error	Insulation problem of PV panel
E02 Leak Error	GFCI fault, leakage current is too high
E03 Grid Fault	Grid voltage / frequency is out of range
