I know that Nadja has some wind generators and solar and that he runs his entire home off grid. TN Andy has enough solar panels in a grid tie system to make his electric bills at or near zero with a few more panels planned. What I'm wondering is how to create a small system that supplements my current grid power without having a grid tie inverter. I have great wind and would love to find a way to reduce my bills. How would I set up a wind turbine that feeds into my home electrical system to offset my utility electric usage? Can I do this without a battery bank? Not looking for backup during an outage at this point. Does the inverter synchronize with my grid power when the wind turbine is producing? Can a system like this be made modular so that it could be expanded in the future?
