SolarEdge Live (Modbus) 1.2

This is the next version 1.2 of the SolarEdge Live (Modbus) QuickApp.

The SolarEdge Live (Modbus) QuickApp represents an advanced integration that provides instant, real-time access to local inverter data without the limitations of cloud-based API’s. This QuickApp uses the Modbus of your SolarEdge Inverter to get the real-time information about your SolarEdge setup. The QuickApp reads the SolarEdge SunSpec Modbus registers and shows the with QuickApp variables requested register values in child devices and labels. The QuickApp runs at an interval setup in the QuickApp variables. A special button is available to adjust the speed up the interval.

Enabling Modbus on SolarEdge Inverters: 
To enable Modbus communication on a SolarEdge inverter, follow these general steps:

• Access the inverter’s configuration menu, either via its control panel or through the manufacturer’s configuration app.
• Navigate to the communication settings.
• Enable Modbus support, selecting TCP/IP for network connections.
• Adjust Modbus parameters as needed, such as device ID and communication port.
• Save your changes and restart the inverter if required.

After activation, the inverter is ready to communicate with external systems or monitoring solutions using the Modbus protocol. Always consult your inverter’s user manual for detailed instructions specific to your model.

Changes version 1.2 (2nd September 2025)

• Changed the main device type to com.fibaro.powerMeter, so it can contain the AC Power value. 
• Added QuickApp variable for the main device register, mainRegister (default = 40084 AC Power). 
• Added default don't 'Save events to History' (saveLogs = false) to the setup of every child device. 
• Disabled the warnings for READ, WRITE and Invalid response. Users can't prevent those errors and to display them as warnings only clutters the logging. 
• Changed the text of the interval speed buttons to the content of the quickapp variables intervalChildsS, intervalChildsM and intervalChildsF. 
• Found a few old SolarEdge Modbus QuickApp names in the code and changed them also to SolarEdge Live. 
• Optimised the register mapping. 
• Changed the default interval timing to 60, 10 and 5 seconds. Of course, you can use your own settings. 
• Removed the expiration date.  

Variables (mandatory and created automatically): 

• host = Modbus TCP IP address of your target device (default 192.168.1.145)
• port = Modbus TCP port (default 1502)
• unitId = Modbus slave/unit address (default 1)
• inverterType = Type of your Inverter (101, 102 or 103, default type 101. Also see the value of register 40070.)
• intervalS = How fast the Modbus will refresh the data (Slow default 60 seconds) 
• intervalM = How fast the Modbus will refresh the data (Medium default 10 seconds) 
• intervalF = How fast the Modbus will refresh the data (default 5 seconds) 
• intervalChildsS = How fast the Childs will update (Slow default 60 seconds)
• intervalChildsM = How fast the Childs will update (Medium default 10 seconds) 
• intervalChildsF = How fast the Childs will update (default 5 seconds) 
• maxResponseTime = Maximum time in seconds for response of the Modbus to disconnect (default = 60)
• debugLevel = Number (1=some, 2=few, 3=all) (default 1)
• Also with the QuickApp variables child devices can be created. Insert a QuickApp variabel with the address as 'variable' and the deviceType as 'value'. By default the values from the childs will show in the labels (except Scalefactor values). You can use all kinds of devicesTypes, for example: 
• com.fibaro.energyMeter (Wh) (by default no storage to energy database)
• com.fibaro.powerMeter (Watt) (by default not used for instantaneous power in Energy Panel calculations)
• com.fibaro.electricMeter (Volt and Ampere)
• com.fibaro.multilevelSensor (Number values)
• com.fibaro.temperatureSensor (Temperature)
