Compact industrial PC for top-hat rail
The industrial PC is a standard solution which has already established itself in applications such as industrial automatisation or telecontrol engineering. The compact PC can be fitted quite simply to a top-hat rail and possesses all the important interfaces (USB, LAN, etc.) as well as two integrated 8 GB Flash Disks. The Microsoft Windows XP® operating system makes the PC extremely user friendly.
Operational management made easy
The heart of the DataInterface is the software which retrieves data from all the electronic components in the photovoltaic system and stores them in a XML file. This format makes it easy to integrate the data into an operational management system or to analyse it using Excel. The archived data (current, voltage, temperature, status messages, etc.) allows a system analysis down to string level and therefore a precise evaluation of the system’s performance over any desired timeframe.
