My first Inspire 1 flight - onshore wind farm in Germany

Looks Great! I am planning to go to Fuerth in June. I live in Los Angeles and was wondering how to obtain the license to fly my inspire 1 Pro there as a Recreational Hobbyist?
Is there some website link where I need to register my drone to fly in Germany? I have already an FAA drone registration for the United States, and was wondering if that is ok for me flying in Germany?
Any advice would be very helpful!
