DEFAULT CONFIGURATION IN TRACKSO IOT GATEWAY
Inverter ID: 1, 2, 3, 4 …. Continuous numbering starting with 1, (Range: 1 to 247)
Baud Rate: 9600 (Default) (Values: 9600, 19200, 38400)
Data Bits: 8 ,Stop Bit: 1 ,Parity: None
CONFIGURATION AT THE INVERTER END
Connect the SUN2000 to the mobile phone that runs SUN2000 app through a Bluetooth module or USB data cable (same as used for
commissioning of the inverter)
After the successful login, the Quick Settings screen or Function Menu screen is displayed
Huawei APP Screenshot
Settings
Set Data & Time
For a precise calculation of the statistics in the inverter itself and in a monitoring
system, date and time have to be correct.
Set Baud Rate
Default Value for configuration TrackSo – 9600
If you connect multiple inverters via RS485, set the same baud rate on each
inverter.
Set Protocol
Modbus RTU protocol is to be selected for proper communication setup between
Huawei and TrackSo IoT Gateway
Set communication Address
The address/ID is used to identify the inverter in a RS485 connection
•Set a different inverter ID for each inverter in the PV plant. Otherwise, the
inverters cannot be correctly identified.
•On the last inverter in the RS485 connection, switch on the RS485 termination
resistor
Communication Card Settings
Single Inverter
Terminal Resistor-off
Multiple Inverters
If multiple SUN2000s are used, connect all the SUN2000s in daisy chain mode over an RS485 communications cable.
Pin 2 & 4 of Inv-1 is connected to Pin 1 & 3 of next inverter in Daisy Chain.
When two or more inverters are in parallel communication, the terminal resistor should be switched on or else, it may cause
communication interruption.
NOTE: The above details are mentioned in the Installation & Operation Manual for SUN2000-(33KTL, 36KTL, 40KTL,55KTL, 60KTL)
or Installation & Operation Manual for SUN2000-(25KTL, 30KTL)
TRACKSO WORKING
1. Insure correct connections as detailed in the installation guide.
2. Insert the SIM card.
3. Switch on the power to the TrackSo device. (Minimum 12V/1A input is required)
4. Power LED (Red) of TrackSo IoT gateway glows and stays ON.
NOTE: TrackSo IoT Gateway will only be able to send data if the GPRS network is available at the installed location.
