Your Questions About Wind Turbine Generators How They Work

How would I go about building a small scale wind turbine to power small items/store excess electricity?

With all this windy weather in the UK at the moment it made me think about designing/constructing a small wind turbine to power small items, i.e. things that would usually plug into the mains and not use that much power, e.g. lamps, etc. How can I go about making one that will power such items and store excess power it produces in a battery or something? I’m sure it will be difficult but any tips will be greatly appreciated. Thank you.

Is a charge controller needed with a 400w wind turbine system with no batteries or just a power inverter?

I am setting up a wind turbine system that only has a 400w wind turbine. I am going to make it a tie in and will not have a battery system to save power. Do i need a charge controller or is only having the power inverter enough
yes i meant a grid tie in.

so i would need to contact my electric company then and ask them what they supply and what i should purchase myself?
