Installing a Replacement Microinverter

1. With the silver side of the microinverter facing up and the black side facing down, attach the

replacement microinverter to the PV racking using hardware recommended by your PV racking

vendor.

2. If you are using grounding washers (e.g., WEEB) to ground the chassis of the microinverter, the

old grounding washer should be discarded, and a new grounding washer must be used when

installing the replacement microinverter. Torque the microinverter fasteners to the values shown:

•

NOTE: Using a power screwdriver to tighten the grounding clamp screw is not

recommended due to the risk of thread galling.

3. If you are using a grounding electrode conductor to ground the microinverter chassis, attach the

grounding electrode conductor to the microinverter ground clamp.

4. Connect the microinverter. There are two latching mechanisms within the connectors. Listen for

two clicks as the connectors engage. Ensure that both latching mechanisms have engaged.

5. Mount the PV module above the microinverter.

6. First connect the positive DC wire from the PV module to the negatively marked DC connector

(male pin) of the microinverter. Then connect the negative DC wire from the PV module to the

positively marked DC connector (female socket) of the microinverter.

7. Energize the AC branch circuit breaker, and verify operation of the replacement microinverter by

checking the indicator light on the underside of the microinverter. You may need a handheld

mirror to see the indicator light.

8. Initiate a device scan at the Envoy. To do this, press and hold the Menu button on the Envoy for

two seconds to bring up the Envoy menu on the LCD window. When the LCD window displays

"Enable Communication Check", release the Menu button.

9. Use Enlighten's Array Builder function to add the newly detected microinverter to the virtual

array.
