Connectivity Protocols from all leading inverter manufacturers are integrated I/O devices (e.g. weather stations, medium voltage parameters) ? SPD´s for all communication ports ? Electromagnetic compatibility EN 61000-4, EN 55011 ? IP65 housing ? Wall-/rack mounted configuration 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.

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” is a data logger 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. This accurate data acquisition and control concept is inverter independent and gives feedback about losses due to inverter malfunction, soiling, shading, PV Module degradation etc. . The Linux based platform can control up to 100MW plants with just one controller and fulfils all international requirements as the IEC 60870 (communication protocol for supervisory control and data acquisition) for reactive power, ramp rates, etc. or Germany’s BDEW (“Erzeugungsanlagen im Mittelspannungsnetz”). Data collection can be down to one second or more, which is often required by utilities to zoom for grid impacts tests. Signal conditioning, data storage and transfer, compressing, and communication in many ways are the strengths of this flexible data solution. For communication industry standard Modbus protocols for easy and fast integration is used which enables reliable data exchange within the network. For longer communication distances fiber optic technology is used. Data transfer is possible by cable (Ethernet/ LAN) or wireless (GPRS/3G or 4G, WiFi) – the loggers meet all standard security requirements (SSL) with lowest power consumption. The data acquisition system grows with the requirements and distributed Q.series measurement modules can be integrated at any time.
