Hello All
I am putting in my off grid system, it will be a 3kw wind turbine with a 3 kw solar system, set up to a battery bank.

I want to have a back up generator for those rare occaisions that there is no wind or sun. 

Should I have the generator hooked to the charge controller to charge the batteries or directly to an inverter to power the home.

Thank You

Hello

I am building a home and plan on being off grid.  My system will consist of wind turbine, with a battery bank.  when I can afford I will add solar modules.  My question is regarding a backup generator.  I want to use a generator for charging the batteries when I do not have wind and the batteries get below a certain level.  do you think a diesel RV generator will be enough or should i go with a larger generator.

thank you

Hello Again.

the wind turbine I am considering can be purchased either as a 24v or 48v, what do you think is a better way to go.

As for batteries, do I need them to be in groups matching the volt output of the wind turbine, i.e. 4-12v batteries or 8-6v batteries, etc. 

what about amp hours.  I was looking at a 12v battery with 212 AH, if I connect 4 of the 12v 212 AH batteries will I have 848 amp hours.

Thank You

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.
