System Fault
Explanation
PV IMPEDANCE LOW
Resistance from either PV inputs to Earth Ground is lower
than 600 kOhm
ISOLATION FAULT
Disconnecting relays between Inverter and Grid do not work
properly
PV GND FAULT
Fault current from PV arrays to Earth Ground
ARC FAULT
Electrical series arcing in PV (DC) wiring
INTERNAL FAULT
Failure of self-test on internal converters in Inverter
