SUNPOWER AC MODULES: NEW INSTALLER CHECKLIST
There are a few other important points to keep in mind before an install (which is different to a
standard microinverter + panel installation):
GET STARTED
Review the Safety & Installation Guide paying close attention to the rail positions
and clamping zones.
Create installation design map to determine panel orientation.
Use the SunPower AC Module Q Cable Management Guide to determine which Q
Cable length you will need.
Use the Enphase BOS calculator to determine additional Enphase components
required to complete your AC module installation.
Ready site (roof) for AC MODULE installation
Install the Field-wireable connector pair, optional J-Box, and Mark your cable
locations
2. Remove the serial number from microinverter on the ground and stick them
onto your sample layout (for array builder in Enlighten)
Ensure microinverter is functional by checking each microinverter’s LEDs:
• The status LED lights green about six seconds after DC power is applied.
• It remains lit solid for two minutes, followed by six green blinks.
• After that, red blinks indicate that no grid is present if the system is not yet energized.
• Any short red blinks after DC power is first applied to the microinverter indicate a failure
during the microinverter startup.
Normal operation. AC grid function is normal and there is
communication with the Envoy.
The AC grid is normal but there is no communication with the Envoy.
The AC grid is either not present or not within specification.
There is an active “DC Resistance Low, Power Off Condition”.
To reset, see “DC Resistance Low – Power Off Condition” on page 21 of
the Enphase IQ7 Installation manual.
For further guidance, see the LED section of Enphase manual.
5. Position the AC module + pull each microinverter out of the cradle before
placing the modules on rail
