    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 one 445 W bifacial solarpanel and 194 Ah of batterys. As controller is a BlueSolar MPPT 75/15 with serialport for data.
    Stuffs what wants power are a RaspberryPi, router/4G-modem, ip-cam, weatherstation and lightningtracker as partipating in the european-wide Blitzortung-network. Total powerneed are ca 210 watt per day during summertime if running everything 24/7 and ca 12 watt during wintertime when running with minimal uptime and lightningradar offline.
