Battery bank confused

pauldb38 Registered Users Posts: 1
Hi ok my setup is 12 volt solar panels with charge controller and 12 volt battery's and a 12 volt wind turbine but i need to change the configuration , i need to use 12 volts still but i also need to use the battery's in a 24 volt configuration , my question is this can i wire the battery bank as a 24 volt system but at the same time charge from my 12 volt panels and wind turbine ?

Kind regards

    Basically, no. You cannot charge a higher voltage from a lower one.

    In theory you could charge half the bank for a while, then the other half, but getting them even would be nearly impossible.

    If you have 12V solar panels in multiples of two, and they are around the same wattage, you could rewire them and charge a 24V battery. However, splitting a 24V battery bank and drawing 12V loads off of half of it is not generally recommended.

    Why do you need to change it to 24 volt? If it's working for you as a 12 volt setup why not keep it that way?
