8.2 LED Fault Indicators
Ground Fault
If the yellow and red LEDs light up simultaneously, the inverter detected a ground fault. The inverter
will not restart automatically after detecting a ground fault.
• Locate the ground fault and rectify it. Observe section 9 ”Troubleshooting” (page 78).
• Then restart the inverter.
CAUTION
Risk of electric shock
Normally grounded conductors may be ungrounded and energized when a ground-fault
is indicated by the inverter.
• Check the PV-system for a ground fault and replace the ground fuse as described in
this document.
GFDI fuse
The ground fault may also trip the GFDI fuse.
In "Turbine" mode, all GFDI fuses are deactivated.
