IQ 6/IQ 6+ Micro Installation and Operation

Troubleshoot When All Circuits Appear Non-Functioning

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 verify with voltmeter that the circuit is turned off. Use Lockout/Tagout

procedures.

C. On the roof, open the Q Aggregator using a standard screwdriver blade on the four captured

screws on the cover.

D. Use a voltmeter or electrical tester to verify that circuit coming to the main lug of the Q Aggregator

is not live.

E. Inspect the Q Aggregator for evidence of loose connections at the main lug or look for multiple

blown fuses. Keep in mind that fuse ends may be coated. It is best to test from main lugs to

spade terminals.

F. Remove tools and/or screws from the Q Aggregator, reactivate the PV circuit, and test for voltage

on the conductors coming from main panel.

G. If no voltage is coming from the main panel check your electrical wiring from the main panel.

H. If there is voltage at Q Aggregator main lug, and if the wires appear to be stripped appropriately

and terminated with orange handles down, continue to the Q Aggregator board removal and

replacement procedures.

Replacing Q Aggregator Parts

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.

Remove Q Aggregator Fuse and Connection Board

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

Lockout/Tagout procedures.

B. On the roof, open the Q Aggregator using a standard screwdriver blade on the four screws on the

cover.

C. Assuming that the Q Aggregator may still be electrified, remove the fuse protective cover by

freeing the tabs closest to the main lug. Set aside the fuse cover for future use.

D. Check for voltage across all fuse terminals. If, and only if there is no voltage at any of the

terminals in the Q Aggregator, remove and tie back the main electrical connections.

E. With the main connections disconnected, use a standard multi-meter, (not a Megger) to check the

PV circuits for obvious signs of short circuits.

F. Physically inspect the cabling and terminations for signs of pinching, insulation damage, or bad

terminations.

G. If none are found, use a screwdriver to hold back the locking tab while depressing the spring clip,

and then use a gentle rocking motion to remove the flag terminal. No electrical connections to the

circuit board should now exist.

H. Use a Phillips head screwdriver to remove the five screws that secure the board.

DANGER: Risk of injury. Do not chase dropped screws. They can be replaced with standard

stainless metric hardware.

I. Set aside the screws for future use.
