Inverter Logger
GPRS / WiFi / Ethernet

By collecting operating status and power generation of inverter, inverter logger can run a long-term and efficient monitoring of PV system. 

Logger can connect to multiple inverters via RS485/422 interface, which enables to collect all the data of PV system from the inverter. 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. Furthermore, customized alerts can notify users of any malfunction or defect immediately via SMS and E-mail, which realizes the management of PV system at anytime and anywhere, also increases work efficiency and reduces management cost significantly.
