3.2 LED fault indicators
3.2.1 Red and Yellow LEDs are on
The inverter has detected a ground fault in the PV system
and has disconnected from the grid. The ground fault
must be located and fixed before the inverter will resume
normal operation. Refer to the installation guide for
information on solving PV array ground faults (the inverter
will not restart automatically).
3.2.2 The Red LED is continously on
Ground fault
The red LED on the Sunny Boy is permanently on. With
this blink code it is irrelevant whether the green or yellow
LEDs are on or blinking. When the red LED lights up
continuously, the inverter has detected a ground fault.
Contact your installer to have the error corrected.
Instructions on correction errors can be found in the
inverter installation guide.
