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 different locations
and check signal strength. A communication check starts automatically after an
Envoy restart. In addition to this automatic check a user-initiated communication
check can be started with the Envoy Menu button or through the administration page
when connected to the Envoy local connection with a computer.
To initiate a communication check:
1. Press and hold the Menu button on Envoy for two seconds to bring up the
Envoy menu on the LCD window. When the LCD window displays: “Enable

3. When the Envoy begins detecting devices (microinverters), the display reads:
The “LEVEL” indicator in the LCD window may display any number of bars
from zero to five. You can assume that the communication check is
progressing normally and that signal strength is acceptable if two to five bars
are displayed. If fewer than two bars are displayed, you may want to try the
following options:
