If you have 48v (or, actually like 70v) going in from solar panels, can you connect it to a 12v battery and still get good watts?
Will it turn 70V 1A into 48V 1A and then 12V 4A, or will it just go from 70V 1A to 12V 1A?

I’m not meaning to be nasty with this response but to ask a question like “If you have 48v (or, actually like 70v) going in from solar panels, can you connect it to a 12v battery and still get good watts” tells me that you clearly do not understand what you are doing. What you are doing is possibly dangerous and if you get lucky and don’t hurt yourself, you will damage the components you have.
I’ve never seen the device you have but it took me all of 15 seconds to find it on the web and to read enough of the instructions to know that this controller has a maximum open circuit input voltage of 55 volts. If you put 70 volts on it, you will mostly likely damage it.
It can then be configured to charge a 12 volt, 24 volts, or 48 volt bank of batteries.
