blue'Log Data Logger

The data loggers record all data from PV systems centrally and ensure compliance with the national and international requirements of grid operators along with country-specific feed-in regulations according to the system size. The new generation results from the continued development of the WEB’log series and offers useful new functionality and a flexibly extensible system to meet the requirements of the future energy landscape. The X-Series sets new standards in areas including safety, installation, maintenance, usability and networking of web portal, and data logger.

VCOM Web Interface

The VCOM (Virtual Control Room) provides a performance overview of your entire system portfolio worldwide – in a straightforward manner and available at all times. In the event of a breakdown, faults are quickly located and rectified very efficiently. The web-based user interface can be adjusted exactly for your needs – for each specific workflow.

Safer Sun

safer'Sun Web Interface

The data recorded by the system data logger is transmitted to the meteocontrol servers and compared on safer’Sun Professional with simulated values for the expected energy production. These values are calculated from the configuration of the system and the present weather conditions. Significant inconsistencies trigger an alarm automatically via email or text message. safer’Sun Professional allows analyses in full depth and simple configuration of all alarm criteria to safely operate a PV system.
