into the existing transmission path from the Sunny Beam to the inverters. The repeater
requires a wall socket for the power supply.
2.2 Functions
Connection to the inverters and to the Sunny Beam via:
• Radio
(up to 325 ft in open air, up to 100 ft in buildings, maximum 4 inverters)
Supported inverters:
• The repeater supports all inverters that the Sunny Beam supports.
Number of inverters supported:
•up to 4
Connection to the power supply via:
• USB plug-in power supply (max. 6 ft)
Display of system states:
• via 4 light-emitting diodes

4 Determining the Installation Location
4.1 Requirements
Observe the following ambient conditions for the repeater's installation location.
• Protect the repeater from dust, wet conditions, corrosive substances and vapors.
• The repeater requires a 120 V wall socket for the power supply.
• The ambient temperature must be between 32 °F and 131 °F.
4.2 Handling the Antenna
With the Sunny Beam Repeater's adjustable antenna, you can adjust the alignment of
the antenna to suit the local conditions.
From the vertical position, the Sunny
Beam Repeater's antenna can be
rotated a maximum of 180 degrees to
the front or to the bottom. From the
horizontal position, the Sunny Beam's
antenna can also be tilted to the left in
two steps of 45 degrees, as illustrated
to the right.
The antenna may be rotated a maximum of 90 degrees to the front or to
the rear. Further rotation damages the cable.

4.3 Determination Procedure
1. Walk with the Sunny Beam into the range of the inverters and activate the Sunny
Beam as described in the Sunny Beam user manual. The inverters must be detected
and registered with the Sunny Beam.
2. Check that the inverters are operating.
3. Walk with the Sunny Beam until approximately three meters from the inverters (not
closer).
4. Set the data request frequency to the maximum frequency (the minimum selectable
interval) via the menu "VIEW OPTIONS/DATA REQUEST FREQ.".
5. Go to the "SETUP/SERVICE/DIAGNOSTICS" menu.
6. Here, you can read the communication quality (see figure below) which is
calculated on the basis of the ratio between the lost data packets and the sent data
packets.
The registered inverters are listed with the last five digits of the serial number. The
following values are also specified:
"S"= data packets sent
"LS"= data packets lost on sending
"LR" = data packets lost on receipt
This is followed by the communication quality calculated in %.
The communication quality specifies the ratio between received and sent data
packets of the registered inverters. With a communication quality of 100 %, the
signal strength is very good and no data packets are lost.
It is important to set the data request frequency back to at least 15 seconds once
you have successfully determined the installation locations of the repeater and the
Sunny Beam. Lower values (under 15 seconds) should only be set for
commissioning purposes (testing the radio connection) and not long-term.

7. Move away with the Sunny Beam towards the desired installation location until the
first data packets are shown to be lost under LS or LR. Then move back towards
the inverters again until no more data packets are being lost.
8. Install the repeater at this location. First connect the provided USB power supply
to the repeater, then plug the power plug into a socket.
The repeater starts up.
All LEDs on the repeater briefly shine green. The repeater starts up. This procedure
takes approximately 1 minute.
9. In the Sunny Beam main menu, select "SETUP/
PLANT" and set a check mark beside the menu
item "REPEATER".
10. Select "EXIT" repeatedly until the prompt window
opens.
11. Select "Yes" in the prompt window. The setting is
saved.
12. Return to the "SETUP/SERVICE/DIAGNOSTICS" menu.
13. You can now walk away with the Sunny Beam towards the desired installation
location until the communication quality is still at least 50 %.
14. If you have reached the desired installation location with sufficient communication
quality, commissioning is successfully completed at this point.
Set the data request frequency back to a value of at least 15 seconds or higher
via the menu "VIEW OPTIONS/DATA REQUEST FREQ.".
15. If you cannot yet reach the desired installation location with sufficient
communication quality, change the repeater's installation location. Even altering
the position by only a few meters may improve the communication quality.
16. After successful commissioning, set the data request frequency back to a value of
at least 15 seconds or higher via the menu "VIEW OPTIONS/DATA REQUEST
FREQ.".

5 Installation
The repeater can be used as a tabletop or wall-mounted device. If you choose to mount
the device on a wall, you can either mount it directly on the wall or on DIN rails.
5.1 Tabletop Device
If you use the repeater as a tabletop device, follow the points below:
• Do not cover the repeater. This can cause the device to overheat.
• Lay the USB power supply cable in such a manner that its weight does not cause
it to disconnect.
• Lay the cable properly so that there is no risk of persons tripping over it.
Only install the repeater once you have determined the appropriate installation
location as described in section 4 "Determining the Installation Location" (Page
13).
