The blue’Log X-Series records all relevant system data, provides various interfaces and functionality for power plant control and thus enables grid-compliant feed-in for PV systems. For the monitoring portal VCOM (virtual control room), the blue’Log X-Series serves as the heart of on-site monitoring. 

To meet the complex requirements of the future energy landscape, we have redeveloped the proven X-Series and the Power Control range for you.

We provide you with two variations of the data logger blue’Log XM (X-Monitoring) and blue’Log XC (X-Control) and facilitate tailored solutions for your individual photovoltaic projects.
