Envoy Installation and Operation

Set Up 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 an eight-hour

scan. This initial scan is the only scan needed for most systems.

NOTE: At sites with more than 100 microinverters, we recommend using the controlled

device scan presented here and specifying the total number of devices to be discovered.

This will speed up the discovery process.

To run a controlled device scan to detect new or previously undetected microinverters:

1. From the Admin menu, choose Device Scan Control.

The Device Scan Control screen appears.

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.

3. Although optional, it is best practice to enter a value for Total Devices. Enter a value in this field.

The Envoy will stop 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 will make scanning its

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 will display the following, where

“nnnn” represents the number of microinverters (devices) detected.
