John, I bought a Braun Antartis 2.5 kw wind turbine in 2019 to replace an old ARE 2.5 kw turbine. The Braun has worked well for the last 5 years. I had to import it from Germany. The old ARE generated more energy, but the Braun is quieter and seems more reliable. https://braun-windturbinen.com/
I only had one incident where lightning took out a board on the controller. It was well grounded and protected by Midnite Surge Protectors, but this was close strike that took out our garage door opener and a few other things as well. They shipped a replacement and it was easy to swap out. Everything is mounted on DIN rails in the control panel.
