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 depends 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.
3. Although optional, it is best practice to enter a value for Total Devices. Enter a value in this
field. The Envoy stops scanning once it has detected the given number of devices.
NOTE: The Total Devices option can be used in conjunction with the Priority Duration option to
help discover any last few microinverters.
4. Enter a Priority Duration (optional) in days:hours:minutes (e.g., 0:00:20 to indicate zero days, zero
hours, and 20 minutes). If you enter a value in this field, the Envoy makes scanning the sole activity
for the period specified.
NOTE: The Priority Duration option should only be used in limited situations, e.g., at large sites
or sites experiencing problems discovering devices with the normal scan.
5. Click Start Scan to complete this task. The LCD screen displays the following, where "nnnn"
represents the number of microinverters (devices) detected.
