1. Introduction
Your solar PV (photo-voltaic) installation when combined with an Enecsys Micro-Inverter, with its
in-built antenna, is able to communicate wirelessly with the Enecsys Gateway. This allows for
comprehensive monitoring of the solar PV array, module-by-module.
Monitoring an array module by module enables the user to see energy generation at module
level. Monitoring also allows the end-user to see the performance of any module at any time of
the day.
An Enecsys Repeater acts as a bridge between the Micro-inverter and the Gateway in situations
where a sufficient communication link cannot be established.
For circumstances where it may be necessary to install an Enecsys Repeater see See“When to
install an Enecsys Repeater” on page 5.
This manual contains information specific to the installation and configuration of the Enecsys
Repeater. Although the installation and configuration is simple a basic knowledge of internet
routers, wired or wireless may be beneficial although not necessary.
Installation of the Enecsys Repeater is a 'plug and play' process. Enecsys have designed the
hardware to be a simple as possible for the installer and end-user alike.

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).

If, after having installed a Repeater in the attic/roof space an ‘x’ indicating that an insufficient
communication link between the Repeater and the Gateway is still displayed a secondary
Repeater can be added (R2).
If the building has a metallic roof as found in an industrial/commercial building then it may be
necessary to use a Double Repeater.
When installing a repeater the Gateway should be placed into installer mode.

2. Installation
Enecsys Repeaters are employed to improve the communication link between the inverters and
the Gateway. The Enecsys Repeater is a 'plug and play' device; it is quickly and easily installed.
The Enecsys Repeater should be installed within the roof-space of the building and positioned
within easy connection distance of a mains supply AC power source.

2.1 Attaching the internal antenna
Attach the antenna to the RP SMA connector on the right hand side of the Enecsys Gateway.
1. Attach the antenna to the lower RP SMA plug on the right hand side of the Repeater, screw
the antenna into place in a clockwise direction.
2. Move the antenna into an upright position.

2.2 Mounting the Enecsys Repeater
The Enecsys Repeater can be either free standing or wall mounted. The Enecsys Repeater should
be installed in a location where it is unlikely to be moved, indoors, usually within the roof-space,
away from heat sources and out of direct sunlight. If choosing a free standing installation place
the Enecsys Repeater within reach of an AC mains power source. It is recommended that the
Enecsys Repeater be placed as high as possible within the building roof-space.

2.3 Wall mounting the Enecsys Repeater (adhesive pad method)
When mounting an Enecsys Repeater always ensure that you have connected the power supply
and antenna to the device before the final fit. Locate the Enecsys Repeater away from metal
structures. The adhesive pad placement areas are shown in Figure 5 on page 9.
1. Ensure that the back-plate of the Enecsys Repeater and the wall or mounting surface is clean
from dust and grease.
2. Attach the antenna to the RP SMA plug on the right hand side of the Enecsys Repeater, screw
the antenna into place in a clockwise direction.
3. Connect the supplied external 5V DC power supply to a mains supply AC power source.
4. Connect the supplied external 5V DC power jack-plug to the DC power port on the reverse of
the Enecsys Repeater, thread the cable through the semi-circular channel on the back-plate of
the Enecsys Repeater, this will help to keep the cable in place and prevent it from becoming
detached.
5. Remove the backing material from one of the double sided adhesive pads and place firmly
onto the fixing points on the back of the Enecsys Repeater. Complete the process for the
remaining two double sided adhesive pads.
6. Remove the remaining backing material from the adhesive pads attached to the back-plate of
the Enecsys Repeater, press the Enecsys Repeater firmly into place on the wall/mounting sur-
face.

2.4 Wall mounting the Enecsys Repeater (screw fixed method)
When mounting an Enecsys Repeater always ensure that you have connected the power supply
and antenna to the device before the final fit.
The screw fixing points are shown in Figure 5 on page 9.
1. Attach the antenna to the RP SMA plug on the right hand side of the Enecsys Repeater, screw
the antenna into place in a clockwise direction.
2. Connect the supplied external 5V DC plug top power supply to a mains supply AC power
source.
3. Connect the 5V DC power supply jack-plug to the DC power port on the reverse of the Enecsys
Repeater, thread the cable through the semi-circular channel on the back-plate of the Enecsys
Repeater, this will help to keep the cable in place and prevent it from becoming detached.
4. Select the appropriate location for mounting the Enecsys Repeater.
5. Using the wall mount template locate the desired position of the Enecsys Repeater; ensure
that there is adequate free-space around the Enecsys Repeater to allow for any future move-
ment or maintenance of the device.
6. Mark two horizontal spots on the wall 50 millimetres apart, install the screws into the wall.
7. Line up the back plate holes of the Enecsys Repeater with the screws on the wall and then
slide the Enecsys Repeater down to fix the unit in position.

2.5 Mounting with a cable tie
When mounting an Enecsys Repeater always ensure that you have connected the power supply
and antenna to the device before the final fit.
There may be situations where it is not possible to mount the Enecsys Repeater using the screw
fixed or adhesive pad method. A cable tie can be utilised to fix the Enecsys Repeater to an internal
pillar or suitable structure.
1. Ensure that the cable tie is of the correct width and length.
2. Run the cable tie through the cable tie fixing point on the back of the Enecsys Repeater.
3. Wrap the cable tie around the internal pillar or suitable mounting object and secure.

2.7 Turning the Enecsys Repeater off
The Enecsys Repeater comes supplied with an external 5V DC power supply. The power adaptor
serves as the disconnect device - a socket outlet in accordance to the national wiring codes for
the country shall be installed near the equipment and shall be easily accessible.
To turn off the Enecsys Repeater remove the 5V DC power supply jack-plug from the power port
on the reverse of the Enecsys Repeater. If the Enecsys Repeater is attached to its mounting
