Install A Replacement Microinverter - enphase M215 Installation And Operation Manual

Install a Replacement Microinverter

1. Verify that the AC branch circuit breaker is de-energised.
2. With the silver side of the microinverter facing up and the black side facing down, attach the
replacement microinverter to the mounting rail using hardware recommended by your mounting rail
vendor.
3. Torque the microinverter fasteners to the values below.

NOTE: Using a power screwdriver to tighten the fasteners is not recommended due to the risk
of thread galling.
4. If you are using a bonding (earthing) electrode conductor to earth the microinverter chassis, attach
the earthing electrode conductor to the microinverter earthing screw. Torque the 10/32 earthing
cleat screw to 2 N m (20 in-lbs) minimum.
NOTE: Using a power screwdriver to tighten the earthing clamp screw is not recommended
due to the risk of thread galling.
5. Attach the bonding (earthing) electrode conductor, if used, to the microinverter earth clamp.
6. 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.
7. Mount the PV module above the microinverter.
8. Mate the microinverter and PV module as required.
9. 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.
10. 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 Device Scan", release the Menu button.
This starts a 30-minute scan at the Envoy to discover the new microinverter.
11. Use Enlighten's Array Builder function to add the newly detected microinverter to the virtual array.
12. Ship the old microinverter to Enphase using the supplied return shipping label.
