    The weatherstation works totally "off-grid" with solarpower. One of the ideas for the project is to check how well it works also during the dark season. As powersource works 270 W panels and batterys. As controller is a BlueSolar MPPT 75/15 with serialport for data.
    Stuffs what wants power are a RaspberryPi, ip-cam, weatherstation and Blitzortung lightningradar. Total powerneed are ca 210 W per day during summertime if running everything 24/7 and less than 10 W during wintertime when running with minimal uptime and lightningradar offline.
