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 22 of this manual.
The Envoy identifies each device by its unique serial number. If a microinverter is
ever added or replaced at your 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 22 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:
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.
Normal Operation
Once the Envoy completes a scan, it begins or resumes normal operation. At this
point, the indicators in the LCD screen show current values for your system. This is
the home screen:
The data on the home screen may take a few minutes to appear after starting up
the Envoy or initiating a scan. Information shown during normal operation includes:
