The QS Data Control Pro internet datalogger provides monitoring, read outs and alarm warnings via internet. In this way you can watch your solar inverter closely, wherever you are connected to the internet.

During the day, the datalogger registers power output from a maximum of 20 connected Sunmaster inverters. Via the QS data port, the datalogger extracts all the required information directly from the inverters. External kWh meters are no longer necessary.

The collected data is sent to a web page at night, where it can be accessed via a log in code from anywhere in the world. Exceptionally accurate weather prediction data is used to monitor the output of the PV system. An important advantage of the system is the link from the local monitoring to the weather registration of Meteo Control in Germany. An external reference cell is not required. This version is delivered with an integrated GSM modem and without enclosure.
