By collecting operating status and power generation of inverter,meter and other devices,DIN-Rail logger can run a long-term and efficient monitoring of PV system. Logger can connect to multiple devices via RS485/RS 422/RS232 and other interfaces.Meanwhile,remote monitoring cloud platform(SOLARMAN Portal) provides powerful data support for the logger.Logger sends the data to the monitoring platform via WiFi/Ethernet/GPRS.The real-time status and historical data can be displayed with graphs,enabling intuitive and clear understanding of PV system.
