The new ISM photovoltaic panel series are suitable for monitoring the energy production of the plant in every single moment.
Thanks to the transducers is possible to monitor the string currents and the overall voltage.
Inside the panel the XCIO4 analogue converters allow to acquire the signals and information from the strings and to put them on the Modbus line.
To setup the system connection it is necessary to use the following Modbus addresses.
Default Modbus addresses:
- • XCIO4IMB-1: STRINGS CURRENT 1-4 ID MODBUS 1
- XCIO4IMB-2: STRINGS CURRENT 5-8 ID MODBUS 2
- XCIO4VMB: PARALLEL VOLTAGE ID MODBUS 3
If the plant has more than one ISM panel, it will be necessary to increment the Modbus addresses of the additional devices, to avoid read conflicts (i.e. if we have a second ISM0801CA10:
ID MODBUS 3+1, ID MODBUS 3 + 2, ID MODBUS 3 + 3). The devices setup can be performed with CaburLab free software, for more information please contact our technical office.
