Review on 400W DC 12V Wind Turbine Generator With Controller For Marine, RV, Homes & Industrial Energy - By Happybuy by Gabriela Alexander

This is advertised as a 500W turbine but I attached a very high speed drill to it an spun it up and it peaked at 22W. On its' own mounted on a 20ft pole in the middle of an open field I have seen it peak at 18W. All three phase wires are properly connected directly to this MPPT controller (https://www.amazon.com/gp/product/B07Z5QZ6RQ/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1). I also tested with the stock controller it comes with but that didn't do any better, the charge light on the controller hardly even lit up. On the positive side it shipped very quickly and was very easy to assemble but takes some welding to get installed.
