Section 5:
Commissioning
WARNING:Follow the steps in the commissioning
pro-cedure in the order they are presented.
Deviating from these procedures could expose you
to lethal voltages that can cause serious injury and/
or death.
WARNING:never insert the GFDI fuse into the
Sunny Boy without the fuse holder base. Lethal
voltage may still be present and electric shock may
result.
CAUTION:Follow the steps in the commissioning pro-
cedure in the order they are presented. Deviating from
these procedures could cause irreversible damage to the
Sunny Boy and void the warranty.
All Sunny Boy inverters have a sophisticated system for detecting and responding
to PV array ground faults as required by NEC Section 690.5. The PV array normally
operates in a grounded configuration. The array’s negative conductor is connected
to the grounding system inside the inverter as a part of the UL1741 Listed ground-
fault detection system. The GFDI protection is active whenever there is sufficient DC
voltage to turn on the LCD in the Sunny Boy.
To commission the Sunny Boy, follow these simple instructions:
1. Make sure any coverting placed over the PV array is removed.
1. Connect the grid voltage to the Sunny Boy by switching on the main AC circuit
breaker in the main utility panel.
2. Switch the DC disconnect to the " on " position: If there is sufficient sunlight
available, the Sunny Boy will enter the „Wait“ mode at this time and the green
LED will begin to blink.
3. If no AC faults are detected, the “Wait“ mode will end after approximately 10
seconds and the green LED will stop blinking, remain on and the Sunny Boy
will begin to operate normally. If an AC fault was registered, the Sunny Boy
will wait 5 minutes prior to starting.
