I have two battery banks. One 48v 400ah bank for my electric motor. One 12v 270ah for the house bank. I want to get some solar panels, but don't fully get it. I have read and read stuff online, but still no definitive answers. So my question is, If I get panels sufficient to charge the big bank, is there some way to switch them to the smaller bank when the big one is full?
Please don't google me.
