IQ 6/IQ 6+ Micro Installation and Operation

Step 6: Replace the Cover

A. Make sure that the drain holes on the bottom of the Q Aggregator are free from debris.

B. Check the seal on all sides for trapped debris. Remove any debris, if needed.

C. Replace the cover on the Q Aggregator and torque screws to 10 in-lbs. (1.1 N m).

D. Check that the Q Aggregator is properly sealed.

E. Cap any unused branch circuit connections using Q-BA-CAP.

The Q Aggregator is now ready for branch circuit connections.

NOTE: To remove a sealing cap or AC connector, you must use an Enphase disconnect tool. Each Q

Aggregator includes one bulkhead connector cap. You can purchase additional caps from your

distributor.

Troubleshooting the Q Aggregator

DANGER: Risk of electric shock. Some tasks are done with live circuits in an outdoor rooftop

environment. Always wear proper personal protective equipment for electrical and rooftop tasks.

One or More Branches Not Generating

Without removing the cover:

A. Verify that the PV breaker at the main panel reads 240V when measuring from L1 to L2.

B. Power off the PV circuit and use a voltmeter to verify that the circuit is turned off. Use

Lockout/Tagout procedures.

C. On the roof, disconnect the Q Cable connectors from all (up to three) of the branch circuit

bulkhead connectors on the Q Aggregator and seal connectors.

D. Turn the PV circuit at the main panel and again verify that 240V is present from L1 to L2.

E. Using proper electrical gloves, arc fault, and fall protection gear, and take care not to short the L1,

L2 pins within each connector. Use a voltage meter to determine if each connector on the Q

Aggregator has 240V present from L1 to L2.

F. If all connectors show proper voltage, then the Q Aggregator is working correctly.

G. If some connectors exhibit proper voltage, but, after repeated testing, other connectors do not

exhibit proper voltage, continue to the Q Aggregator board removal and replacement procedures.

H. If all connectors do not show voltage and the main PV circuit from the main panel is active per

step D, continue with troubleshooting procedure following.
