1.4 Enecsys Double Repeater
The Enecsys Double Repeater provides a ‘hop’ between nodes in a network. The Enecsys Double
Repeater is used to allow communication between the Micro-inverters and Gateway where the
propagation losses are too high for a reliable communication link, particularly where metallic
structures prevent RF propagation. There are various implementations of Enecsys Double
Repeaters, more than one Enecsys Double Repeater can be used to cover larger distances. An
Enecsys Double Repeater differs from a Single Repeater in that two antennas are used. One
antenna can be connected via coaxial cable to an external antenna, positioned on the roof, close
to the inverters. The second antenna communicates with the Gateway located in the house.
1.5 When to install an Enecsys Double Repeater
Depending upon the house construction and build materials it may be necessary to add an
Enecsys Double Repeater in order to provide stable communications between the inverters and
the Gateway over a long time period. An Enecsys Double Repeater is used in situations where a
Single Repeater is unable to provide the Gateway with a strong sustainable communication link.
The Enecsys Double Repeater acts a bridge between the Micro-inverter and the Gateway,
improving the communication link and providing an uninterrupted flow of information between
the two devices. Certain building materials can prevent a strong signal from being established in
the communication link.
• 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.
