    Hello all, I have a 500w pma 12v. My battery bank is 6 6volt wired to 12v. here is my question----Can I wire the generator straight to all 6 batteries individually? that way it starts to charge them when the generator hits 6v. in theory it dont sound like it will work because of + and - hooked together in between 2 6v batteries. What I dont know is will the batteries soak up the power and not make it a short to the generator? Hope I explained this well enough for you to understand.

    I think you explained it okay but I can't quite give you a good answere. Maybe seris is okay and parallel is okay but not at the same time. I've had a lot of gin tonight.

    Anyone else?

    ok, little bit confusing. if they are wired as a 12 V bank they are no longer individual 6 V batteries, your load
    is 12 V.

    But lets pretend you are able to feed a 6 V battery individually,then how are you going to use that 6 V power and on what ? If you want to use it to run power tools or household items, you will end up using an inverter which will require either a 12 V or 24 Volt inverter to convert your power..
    no gin for me but I did drink two diet pepsi today. :lol:

    I understand the wiring. I have them in series/parallel to make (6) 6v into (3) 12v. I wanted to hook the wind generator to each 6v battery so they will start getting charge at say 75rpms rather then the 150 rpms it takes to get to 12v. That way for the light wind days they will still get a charge. I am using them with a standard dc to ac inverter. I really dont think it will work but I didnt know if I might have been missing something that says it will.

    It's a good thought dlmcbm and one could theoretically charge at one voltage then manually switch over to another voltage but it would be very inconvenient and involve a bulky wiring system and very heavy duty (and fairly expensive) dpdt switch.
    I have a similar system to this on my electric bike where I charge at 12 volts then switch over to 24 volts to run. Works ok for an ebike but not very practical for wind and/ or solar power system. Figure also that you wouldn't gain much at such low voltage/ amperage.
