Wind, Solar, Propane Generator Combo

Hello All

I am new at renewable energy and have many questions.  My Wife and I are in the process of building a home.  The cost to bring in electricity is about 17k so we thought we might try Off-The-Grid.  We will be going with Wind, Solar, and Propane Generator Combo.  The Whisper 500 from Southwest seems to be the turbine we are leaning toward.  Our property gets quite a bit of wind.

The First of many questions that I have is.  Is there a particular component that ties all three electricity producers together and distributes the power.  What I mean is determine the needs.  Example 1.  Batteries are at full charge and wind is blowing at a good clip so I would like the wind power to feed directly to the house. 

example 2.  No wind, no sun and batteries have dropped to 70% so I would like the Propane generator to kick on to keep the batteries charged.

Or Maybe there is plenty of sun, the batteries are charged and I want the solar to feed directly to the power needs of the house?  I hope I am clear as to what I am asking.

Thank You

Al McCall

My Xantrex SW inverter will do what you are wanting and I am sure there are probably others. The new XW series are probably even better.

Re: Wind, Solar, Propane Generator Combo

 I am using 2 sw5548 power panels or its called xantrex sw5548/d except I use the outback mx60 controller recomended because its better than the xantrex controller 11000w. This runs my generator kohler16kw when needed in winter{no transfer switch needed in generator if you have one in power panel. and converts my electric to 110v and 220 v . I spent around 20k for everything
16- 245 amp gel batteries for 47,040 watts of storage hooked up for 48v.  6 sharp 208watt pv modules and an airx wind generator. I have enough storage for 3 days of use with no sun or wind before the generator kicks in to charge the batteries.The wind is useless where my house/cabin sits so the solar works best.I have everything a house needs for normal except an air conditioner those suck power mucho. I set my generator to turn off after 1 hr of charging and it only is needed when my solar is covered with the snow. good luck and hav fun learning, Jim
