Envoy Installation and Operation

Performing a Communication Check

If, when you are installing the Envoy, you are unsure of where it should be located for maximum

performance, you may want to install the Envoy in various locations and check signal strength.

Normally, a communication check starts automatically after an Envoy restart. Alternatively, you can

initiate a communication check with the Envoy Menu button, or through the administration page

when connected to the Envoy local interface with a computer, or via Enlighten (Refer to “Using

Enlighten to Check Envoy Status” on page 23).

NOTE: If a Priority Scan is active, the Communication Check will not occur until the

Priority Scan has expired. If you need to run a Communication Check, you can unplug

the Envoy and then plug it in again or wait until priority scanning has ended during

which time the signal bars will return.

NOTE: Device scans and communication checks can only be done during daylight

hours when the microinverters are powered by the PV modules.

To use the Envoy Menu button to initiate a communication check:

1. Press and hold the Menu button on the right side of the Envoy to bring up the Envoy

menu on the LCD screen.

2. When the LCD screen displays “Enable Communication Check”, release the Menu

button.

The LCD screen then reads:

The Envoy begins a 20-minute communication check to assess the signal strength

between the Envoy and the microinverters detected at the site. Until the Envoy begins

detecting microinverters, the display reads:

When the Envoy begins detecting microinverters, the display reads:
