3 Envoy Operation
Starting the Envoy
It takes less than five minutes for the Envoy to be ready to work after applying
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” indication in the LCD window.
Normal Boot Sequence
After the Envoy establishes an IP address and Internet connectivity, the Envoy
contacts an NTP (Network Time Protocol) server so that it can set an accurate, local
time.
How the Envoy Scans for Microinverters
A newly installed Envoy automatically performs an initial scan to discover its
associated microinverters. This initial scan continues to search for new
microinverters for one week 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 one-week time-frame. This scan identifies all microinverters at the
managed site. This one-time process is not repeated. During the scan, you will notice
some of the values increasing on the Envoy’s LCD display.
NOTE: If the Envoy is power cycled (power turned off and on) during
this initial one-week scan, the week-long scan will resume.
The Envoy identifies each microinverter via the unique serial number assigned to
each microinverter. If a microinverter is ever added or replaced at your site, you
must initiate a new scan so that the Envoy can “see” the new microinverter.
