Step 8: Complete Installation of Junction Box or an Enphase Q Aggregator 

A.  Connect the Enphase Q Cable into the Enphase Q Aggregator. A ground lug is provided on 

the Q Aggregator for convenient module/rack/balance of system (BOS) grounding. 

 

B.  Refer to the wiring diagrams on page 40 for more information. Wire colors are listed in the 

following table.

Step 9: Connect the PV Modules 

 

WARNING

: Electrical shock hazard. The DC conductors of this photovoltaic system are 

ungrounded and may be energized. 

 

A.  Connect the DC leads of each PV module to the DC input connectors of the corresponding 

microinverter.  

 

 

 

B.  Check the LED on the connector side of the microinverter. The LED flashes six times when 

DC power is applied. 

C.  Mount the PV modules above the microinverters.
