@alan connell Wind turbines require a significant amount of understanding & control to connect to a battery ESS of which is generally not included with domestic sized wind turbines. With out this level of control and expertise you risk damaging all of the other components on the same system, especially in the event of a grid failure.

I also looked at a wind turbine for my system for providing power when there is no or insufficient solar generation and its just not practically viable. Either the kwh generation is too small or the cost of a proper system is too expensive. Then incorporating the controls required to be able to stop the generation in the event of a grid failure to prevent overcharging. Then there is the noise issue especially in a urban area.
