MPPT controller - voltage sensing without separate wires?

Soon to be released MPPT 3048 will have battery voltage sensing wires optional. Before they were standard. Now it is supposed to sense the battery voltage through main terminal cables, if I'm correct....

"but you want to stay inside the 45amps limit.

Not really
You want to stay within the WATT limit on th einput side for the operational voltage 12, 24, 36, or 48"

Argggh! But you said if you go close to the 45 the controller will heat up and you want to stay well below that limit. Now you don't care if you go over the 45?

I meant just use bigger panels at the same Voc to get more wattage as one choice.
