Device Scan Control
The Controlled device scan differs from other Envoy device scans in that it allows control over scan
period, scanning method, and number of devices. When first installed, the Envoy initiates a seven-
day scan. This initial seven-day scan is the only scan needed for most systems.
NOTE: At sites with more than 100 microinverters, we recommend specifying the total
number of devices to be discovered in order to speed up the discovery process. See
the following procedure for details.
A controlled scan should only be run as needed to detect new or previously undetected
microinverters. You may want to use this feature in instances where you need to run a controlled
device scan for a large site or for a site with communications issues.
To run a controlled scan:
1. From the Admin menu, choose Device Scan Control.
2. Enter a Scan Duration in days:hours:minutes (e.g., 0:00:60 to indicate zero days, zero
hours, and 60 minutes). The scan duration will depend on many factors, such as
number of devices to be detected and quality of power line communication. You may
want to start with a one-hour scan and increase the duration as needed.
