Envoy Installation and Operation

Envoy Operation

First Scan for Microinverters

A newly installed Envoy automatically performs an initial scan to discover all of the microinverters

that are installed and powered up at the site. This initial scan continues to search for new

microinverters for seven days from initial start up of the Envoy. The purpose of this long scanning

period is to account for additional microinverters that may be installed during this initial seven-day

time frame. This one-time process is not repeated. During the scan, you will notice some values

increasing on the Envoy display.

NOTE: If you power up the Envoy, even for just a few minutes, the seven-day scan

begins at that point. If you then power it back down and leave it off until you are ready

to discover the microinverters, the initial scan may have expired. A new scan can be

initiated, and will be required if the installation is done in stages over more than seven

days. The steps for initiating a new device scan are described on page

18 of this

manual.

The Envoy identifies each device by its unique serial number. If a microinverter is ever added or

replaced at the site, you must initiate a new scan so that the Envoy can discover the new

microinverter. The steps for initiating a new device scan are described on page 18 of this manual.

After the Envoy has detected at least one new device, it will automatically enter Priority Scan mode.

The LCD screen will display the following, where “nnnn” represents the number of microinverters

(devices) detected.

NOTE: No power production data will be collected or displayed on the Envoy or in

Enlighten while Priority Scan is active. Also, the Communication Check function will not

operate during this period.

When the Envoy does not detect a device during a polling interval (usually 5 minutes), it will exit

Priority Scan mode. If, subsequently, the Envoy detects another device, it will return to Priority Scan

mode. It will remain in this mode until it again completes an interval where no devices are

detected.

LCD Screen Displays at Start Up

After a power outage or Envoy shut down, it takes less than five minutes for the Envoy to be ready to work

after reapplying power. This five-minute period is known as a boot sequence. You will know the Envoy

has completed booting and has started normal operation when it displays both an IP address and the

“+Web” status indication in the LCD screen.
