Effective PV Monitoring requires constant, solid and traceable PV Plant monitoring data in order to determine actual performance and fulfil owner/investor expectations.
Operators are interested to identify errors and losses in a reliable way to trigger appropriate actions for maximizing energy harvest during the total system lifetime.
The “Q.reader cabinet” is a solution which can make the logging and control of all required PV plant information:
String level (current, voltage), inverter data, meteorological data from weather stations, grid measurements and other state variables (switch gear, transformer status).
At the same time, it also acts as the power controller for the grid operator.
