Thanks I found it the simple answer. I know how solar works I just needed the numbers.

What is the minimum input voltage for MPPT solar charge controller?

The minimum input voltage should be at least 5 volts over your battery voltage.

If the voltage is not high enough, the charge controller will not start.

Just to put some numbers to it. If your 12V battery is partly charged at, say, 13V MPPT charging will not start until the panels reach 18V.
