While I am looking at getting a windtura 750 at least to start I know I can use a 12v or 24v battery bank. The 12v would start charging at a lower wind speed but if I can get the wind speeds 24v is better. My question is if I get a larger wind turbine that has a 48v and up voltage delivery would I still be able to use the 12v or 24v battery banks or need to build a 48v battery bank? Since if I do go to a larger wind turbine as my main I will most likely setup the windtura in another location and continue to use it, it just probably will not be as high. Thank you just researching, researching, researching and looking to the future.
