    I am building a 12 Volt Wind Turbine to produce electricity. I want to output the electricity through a grid tie inverter that requires 14 - 24 Volts of DC current. Can I wire up (2) 12 volt batteries in paralell and series to charge at 12Volts and output to the inverter at 24 Volts?

    You will not be able to wire 2 batteries in parallel AND series, if you are charging at 12 and running it at 24 Volts, this will create a direct short on one of your batteries..... only thing I could suggest is that wire in a DPDT relay to where when you are charging, they are parallel, when using the power switch to series.... but the only down side is that you wont be able to charge and use the power at the same time....:(

    I have built a windmill generator myself >>

    This is just a crazy idea - somewhat inefficient due to the steering diode losses - but no electro-mechanical parts to wear out.

    Cost will be a significant factor of course!

    Just shows you can do something electronically if you really want to "solve" the problem.

    Good luck with the project.
