hi,
i have been given a 170w OC 44v solar panel but am not sure how to connect it to a fan or a battery...a fan is 12 v so hooking it directly would blow it up I assume and so is a battery,so how do i run these items at 12 v,,,if i dont use a battery the watts will fluctuate with the sun,,,do i need a controller of sorts?
thx.
