Solar eclipse without safety goggles: blue’Log provides live broadcast

Our eclipse video impressively shows the progress of the solar irradiation during the partial solar eclipse on March 20, 2015. The live values come from the blue’Log, our new device for remote monitoring of photovoltaic systems. Particular highlight of the new blue’Log X-Series is the remote access to the data loggers: besides remote configuration without additional configuration of the router displaying of live values precisely to the second is easily possible. The blue’Log X-Series is not only suitable for watching solar eclipses but also indispensable for commissioning and on-site services.
