with any other events at the site, such as a power-outage, lightning activity, or other change in the
electrical environment?

The PV modules are dark and no production displays in Enlighten

Modules that are shaded gray, with no indication of production level, have temporarily lost connectivity
with the Envoy. This is different than a unit that is reporting, but reporting 0W AC power.
Communication outages may be caused by poor power line communications, or by DC voltage that has
slipped below the level required to turn on the microinverter. Microinverters that are not powered on do
not communicate with the Envoy.
1. Use Enlighten or the Envoy interface to check for an event on the affected microinverter.
2. Is there a corresponding Microinverter Failed to Report event for this unit? Refer to
"Microinverters are not detected, or, power line communication level is low or poor" on page 22.
3. In Enlighten, select the module and view the production history. When did the microinverter last
report to Enlighten? See "Run a report to view production history" on page 31 or "View module
production history" on page 32.

Enlighten does not allow me to select the PV module

This position in the array has no serial number associated with it. Use Array Builder to assign the serial
number to that spot in the array. If the serial number has not yet been detected, see "Microinverters are
not detected, or, power line communication level is low or poor" on page 22.

View the PV module production history

To view production history for a PV module, refer to "Run a report to view production history" on page 31
or "View module production history" on page 32.

Run a report to view production history

The following system-wide reports are available in Enlighten from the Reports tab.
 Site Energy Production – Lists the energy produced by day and the total production for the
selected time period.
 Monthly Energy Production Report – Lists system energy production by week for the selected
month. This report also lists peak power for each week and energy production for the previous
month and year-to-date.
 Site Recent Power Production – Lists system power production measurements for the past seven
days in five-minute increments. The report shows zero production during intervals when sunlight
is unavailable or when the system is powered down.
 Power Meter Report – This report is only available for systems that have a Revenue Grade Meter
(RGM) installed. It lists the Energy and Power delivered by the system, as well as the Cumulative
Energy in 15-minute increments for the selected date range.
 Per Module One Day Energy Production – Lists daily energy production by module (microinverter
serial number) as well as the total system production for the selected day.
Per Module One Month Energy Production – Lists the monthly energy production by module
(microinverter serial number) as well as total system production for the selected month.
