Consistent Fault

The yellow LED remains lit.

The Sunny Boy has detected a fault with the internal utility monitoring system. When
the inverter detects a fault of this kind it will no longer connect to the utility grid. To
correct this, the inverter must be serviced by a qualified service technician.
