1.4 Enecsys Repeater
The Enecsys Repeater is designed to provide a ‘hop’ between nodes in the network. It is intended
that the Enecsys Repeater be used to allow communication between the Inverters and Gateway
where the propagation losses are too high for a reliable communication link within the
installation. There are various implementations of Enecsys Repeaters and more than one Enecsys
Repeater can be used to cover larger distances with more ‘hops’.
1.5 When to install an Enecsys Repeater
Depending upon the house construction and build materials it may be necessary to add an
Enecsys Repeater in order to provide stable communications between the Micro-inverters and
the Gateway over a long time period. An Enecsys Repeater is used in situations where a
sustainable communication link between the Micro-inverters and the Gateway cannot be
established. Enecsys Repeaters may need to be installed for the following reasons.
• A roof may be made out a metallic material or be a foil insulated.
• The distance between the micro-inverters and the wireless antenna is too great.
• UV screened windows.
If a sufficient strength of communication link cannot be established it may be necessary to install
either a Repeater or Double Repeater.
Figure 2 on page 6 shows typical placement positions for
Repeaters and a Gateway.
In domestic installations where the Gateway (G) is on the ground floor and the building is on
multiple levels a Repeater can be installed in the attic/roof space (R1).
