The GFL function provides correct results with the following conditions:
 Test carried out with Vtest ≥Vnom on a single string disconnected from inverter, from overvoltage protections and earth
connections.
 Test carried out upstream of possible blocking diodes
 Single fault of low insulation located at any position in the string
 Insulation resistance of the single fault <0.23M
 Environmental conditions similar to those in which the fault occurred
