Volts alone have no meaning, you need to measure Watts =Volts x Amperes when the wind turbine charges an almost empty battery through a charge controller
Thanks have been doing it now for a few months. Absolute peak during a storm was 136 watts. Windy day around 15 watts. I use a "Vicron" MPPT to measure with. The battery does not get full, the small consumption that the Vicron has is more than what I get from the generator over time.
