Not sure if this question as being asked before and if it has im sorry.

I have a garage around 20metres from my house. It is currently running from a connection to the main fuse board in the house.

If i purchased a 1Kw wind turbine with the relivant batteries and inverter would the following be possibe?

Could i use an Automatic Transfer Switch as used in back up generators. But have my battery bank as the number one power sourse and the grid as a back up power when the inverter automatticaly switchs off due to low voltage?

I hope thats been worded ok to make sense and before anyone asks it would not pay to have Grid Tie Inverter installed.

Hoping for some help, thank you all.

The problem you have is the amount of power a typical house needs.

If you have a 1kw inverter it will be enough for your lighting if you have low energy bulbs and maybe a few other items. However a kettle draws anything upto 3kw an immersion heater anything up to 5 kw and an electric shower anything up to 10kw. If you are selective on what you power then it is perfectly feesable.

I would say it should work ok ,I have only worked on the manual type switchs and all they do is isolate one feed while connecting to another
I would assume the auto ones do  exactley the same but are automatic. Do you need it to bee automatic - if not the manual ones are alot
cheeper to pick up.
