Chapter 5 Using Enecsys Repeaters
The Enecsys gateway receives signals from the micro inverters on the roof and broadcasts
the data over the Internet to the Enecsys Monitoring server. If the gateway cannot receive
strong enough signals from micro inverters, a repeater installed nearer the PV modules on the
roof will receive the signals, boost them, and then relay them to the gateway.
In some cases it may be necessary to install more than one single repeater to boost signals
two or more times before they reach the gateway.
5.1. Failure to establish reliable communications
• If the Enecsys gateway displays the check symbol “ ” on the Default View screen, com-
munications link between the gateway and the inverters is established and is reliable. See
“Figure 20. Enecsys Gateway Default View” on page 23.
• If the gateway does not display the green check symbol, the communications link may not
be strong enough to be reliable. It may be necessary to install one or more single repeaters.
See “5.3. Installing one or more single repeaters” on page 21.
5.2. Using Repeaters
• If the “X” symbol is displayed on the gateway Installer Mode communication status, one
or more Enecsys single repeaters can be used. Start with one and observe for the “X” to
change to a “
”.
• If the “?” symbol is displayed, signal quality is poor. Distance between the inverters and
gateway may be the problem: installing a second single repeater may help.

and the Enecsys gateway on the ground
