For internet connection, you will need either a network cable (Cat5 or Cat6), or optionally available accessories such as a WLAN stick, a GSM modem/LTE router, or an analog modem.



Additionally, a shielded bus cable is required for connecting the inverters.







The manual is structured chronologically to guide the practical process of commissioning.



CAUTION! Before wiring the SmartDog® to the inverters, they must be disconnected from power. First, the AC side must be disconnected, followed by the DC side. After disconnecting from power, a waiting period of at least 5 minutes must be observed to allow the capacitors to discharge!




Assembly of the SmartDog: 


Cable routing inside the housing


Insert the cables into one of the cable glands. Break the corresponding predetermined breaking point on the housing cover using needle-nose pliers. Optionally, trim the breaking point slightly with a knife if necessary.

Interconnecting inverters:


Connect the first inverter's RS485 terminal block OUT to the second inverter's RS485 terminal block IN.

Connect additional inverters to each other in the same manner.

Terminate the last inverter according to the inverter's instructions.



Assigning communication addresses:


Recommendation: Sequential numbering starting from 1.

Default setting in the inverter: Communication address 01.

Setting: Via the inverter's control display.







At this point, we only present the basic configurations of the SmartDog device. For comprehensive information and a complete guide, please contact EcoData Solutions or simply click on the following link:

After the initial startup, SmartDog® doesn't contain any configuration. Therefore, you will be guided through the individual configuration steps via a "Wizard" (Assistant).


1: Language Selection 

            Select the desired language on the display.


2: Online/Offline/Local Mode Setting

            Select "Online Mode" when the system is connected to the internet.


3: Internet Interface

            In the online mode, select your internet connection that you have connected.


4: Import/Export Manager

            In the Import/Export Manager, you have the option to enable periodic backup.


5: Portal

            Specify how often the data from the device should be sent to the portal.

6: Time Setting


7: Bussystems


Selection of the connected bus(es): 

Specify which bus input (1-2-RS232) you have connected the inverters to. Activate the termination resistor if the SmartDog is the last device on the bus.

12: Exchange of device

For inverters where the bus address cannot be set via the display, in case of a defective inverter, you must assign the address of the old inverter to the new one so that it can take over the collected yield data, etc., from the old inverter.


13: TCP/IP BUS hybrid inverters

16: System

17: Password

18: Updates


Please read the SmartDog manual for further information about these settings.  -




Settings on the Inverter 


On the inverter, all you need to ensure is that the address is set to “1”.

For the 4G and 5G series, you can set the address via the inverter display:


  1. Navigate to “Settings”
  2. Select “Set Address”
  3. Verify that the address is set to “1”





For the S6 series, you can set the address via a direct Bluetooth connection to the inverter.

If you encounter any connection issues, you may consider removing the EMS system and connecting a Datalogger directly to the inverter. If the Logger successfully goes online and sends information to Soliscloud, you can be assured that the RS485 connection on the inverter side is functioning properly.

For detailed instructions and assistance with configuring the SmartDog device, please visit the official SmartDog website at: The SmartDog Support team is available to answer your questions and guide you through the configuration process. If you encounter any issues on the Solis side, please do not hesitate to contact your Solis Support.
