The communication board SMA-232PB-NR allows communication between the SunGuard datalogger and SMC and Sunny Boy inverters.
Through it you can download the data of the PV plant and send them, through internet, to Web Server SunGuard, where they will be processed.

This board is connected to the RS485 serial port on daltalogger SunGuard.
For the monitoring of a PV system you will need many SMA-232PB-NR boards as many SMC and Sunny Boy inverters are installed on the system.
