Connect a standard CAT cable between the RS485 connector on the SOLIVIA gateway
and the RS485 connector on the SOLIVIA solar inverter. See step 1 in gure 4 below.
Connect an Ethernet network cable between the SOLIVIA gateway and the internet
connected network point. See step 2 in gure 4.
You are able to connect the digital inputs to a given function. This concerns the control
of the power the inverter feeds to the grid (power management) and of the power factor
(reactive power control).
If your local public grid supplier requires a remote power derating capability, this can
be implemented by using a ripple control receiver. Please connect the ripple con-
trol receiver as shown in gure 3. After the conguration as shown in Chapters 10.5
and 10.6 the public grid supplier is capable to remotely limit the maximum power the
SOLIVIA solar inverters provide to the public grid.
10 Operation and installation manual SOLIVIA Gateway M1 G2
The ripple control receiver that controls the power management (power limitation) has
to be connected to the inputs 1 to 4. The receiver that controls the power factor (cos
phi) has to be connected to the inputs 5 to 8.
After connection of the ripple control receiver(s) the gateway has to be congured in
order to do the required control of the SOLIVIA solar inverters. For further information,
please refer to Chapters 10.5 and 10.6.
Of course it is also possible to connect only one ripple control receiver, i. e. the one that
controls the power management.
Figure 3: Ripple control receivers circuit diagram
The cables connecting the SOLIVIA gateway with the ripple control receiver(s) should
meet the following specications:
• Max. conductor cross-section: 0.5 mm2 (AWG20)
• Min. conductor cross-section: 0.14 mm2 (AWG26)
• Tightening torque: 0.12 – 0.15 Nm
• Max. cable length: 2 m

Risk of death or heavy injury due to dangerous voltage
► Repairs on defective cables should be done by quali ed electri-
cians only!
► Only recommended and / or commercially available cables
should be used.
This function works only for SOLIVIA solar inverters of the 4th generation!
12 Operation and installation manual SOLIVIA Gateway M1 G2
After installation, the gateway checks the connection to the Ethernet and to the inverter.
• If the Ethernet connection (connection to the internet resp. web portal) works, the
gateway sends a message to the inverter. The following message appears on the
display of the inverter: "Portal Connection ok".
• If the Ethernet connection is not working, the following message appears on the
display of the inverter: "No Portal Connection":
Both messages will be displayed for 120 sec.
If the message "No Portal Connection" appears on the display, please check the Ether-
net connection of the gateway and your internet connection.
If no message appears on the display, please check the RS485 connection between
gateway and inverter and ensure that all inverters have unique RS485 bus IDs.
The gateway has one single LED visible on top of the housing of the gateway. After
power up, it immediately starts scanning for connected inverters. So the LED is con-
stantly ON (no blinking) until the scan is nished.
After that the LED change to one of the following behaviors:
Constantly ON (no blinking) Neither Ethernet nor inverter connection.
Fast blinking (300 ms) Ethernet connection but no inverter connection.
Slow blinking (1 s) No Ethernet connection but inverter connection.
Hinking 200 ms on,
1800 ms off Ethernet as well as inverter connection is online.
Extremely fast blinking Indicates for one second that the reset button has been
pressed.
If one connection (Ethernet or RS485) works, try to exchange the cables. If now the
other interface works it is very likely that one cable is broken.
The HTTP-server implements a browser interface allowing you to congure the gate-
way and to display several information. The features are:
• Log in
• Conguration
• Display information about inverters

Here you can set the baud rate of the gateway for the RS485 communication. The
value should match the one of the inverter(s). The baud rate "19200" is set by default.
Please note, that the RS485 cable lengths is depending on the baud rate. Cable
lengths should not exceed 1200 m if baud rate is 19200 (default value).
If you are using a RS485 wireless modem, please check the box.
Every few seconds, the gateway is retrieving data from the SOLIVIA solar inverters.
The gateway stores these data and sends the average values to the database. Here
you can dene the intervals in minutes of how often the average values and param-
eters are sent to the database. By default, 15 minutes is set.
The gateway does not know the number and addresses of connected inverters in
advance. It is assumed that each inverter connected to the bus already has its unique
address in the range [1, 254]. Address 0 is not allowed and 255 is the value used for
broadcasts.
Please check the SOLIVIA inverter user manual for instructions on how to select the
inverter ID.
Usually the list of inverters gets only longer. Every inverter that was once detected by
the gateway will remain in this list. By pressing the "Start" button the list will be can-
celled and the RS485 bus will be scanned for connected inverters.
The gateway is designed to connect to a maximum of 32 devices.
At power-up, start-up and each day at about noon the gateway scans the RS485 bus
for all connected SOLIVIA solar inverters.
• Start from address 1 up to address 254. Address 0 is invalid and address 255 is
the broadcast address.
During the usual operation the gateway collects only the data of the inverters in the
inverter list. If a new inverter is connected at e.g. 2:00 pm, this inverter will only be re-
cognized after a new scan (latest the next day at about noon).
17Operation and installation manual SOLIVIA Gateway M1 G2
ENGLISH
To reset the gateway to production settings press either the reset switch for more than
5 seconds or click on the "Reset" button. After reset of the gateway, the default values
shall become used again requiring a new conguration if needed.
All the inverter data are cleared, the device is reset and a new RS485 bus
scan starts, ending with a ash store. The settings of Power Balancing,
Power Management, Power Factor Control, Baud-rate and send interval
remain unchanged.
By pressing the "Restart" button the gateway will be restarted. This restart has no
impact on any congurations set before.
The SOLIVIA gateway gives a voltage to the output A and measures the inputs 1 to 8.
In this way the SOLIVIA gateway can detect the state of the relays of the ripple control
receivers. The information which relay shall control what parameter has to be commu-
nicated by the public grid supplier.
Example: Information from the public grid supplier: If relay 2 is closed then the power
factor (cos ϕ) shall be set to 0.93 capacitive, if relays 1 and 2 are closed then the power
factor shall be set to 0.98 inductive.
If the reactive power control receiver is connected to the SOLIVIA gateway as shown
in gure 3 (Chapter 7.5) then the “Power Factor Control” should be congured like in
gure 5.
18 Operation and installation manual SOLIVIA Gateway M1 G2
There are four binary inputs that control the maximum power the inverter may feed into
the grid.
Power management is at 100 % for all relay state combination except 60 % for relay 1,
30 % for relay 2, and 0 % for relay 3 (default settings).
The power factor conguration page allows the denition of 15 values for the cos φ,
either inductive or capacitive. If all inputs are inactive the cos φ is 1.00.
The values are entered in the form 0.xx, e.g. 0.95 and a checkbox decides whether it is
leading current (capacitive) or not.
Please remember to save the congurations by pressing the “Submit” button.
1) This chapter is only relevant for countries, in which your public grid supplier requires a power reduction
(power management), power factor control and/or power balancing.
