It is a wind genny, putting out anywhere from 350 to 400 . I only have a lead acid battery.about 90 cranks.It is a Cat battery. I just want to know what the pioneers of wind gennies used before regulators, if anything...I've heard of people using 12 volt relays. If this can be done, the relay would click in at about 13 volts to a dump load such as a heating element. I don't know if this has been done , but I would like to be able to do it.Thanks.
