15A MPPT/ 12v Batts/24v Solar Panels
I don't see in the info' at hand any information for the use of 24v Panels with 12v Batts. Hmmm? Will this combo work? What is the solution? The reason I have 24v panels is/was for use with the 2...

You do need a MPPT controller to use a 24v panel with a 12v battery. There are work arounds but you lose a lot of the power available.
Don't you have a 200+ watt panel. 15a may not be enough. My 230w panel gets above 16a and a 15a controller would just clip the extra. There is also the concept that you need a 20% buffer meaning at least a 20a mppt controller.
The Eco-worthy 20a MPPT controller I use isn't the cheapest at $100 but I can vouch that it is functional, adjustable and keeps our batteries very happy even with the panel flat with only morning sun.
The work arounds I know of are a PWM controller that could handle high voltage panels. About the same price but you lose the high voltage advantage. I've heard you could connect the panel directly and disconnect it when the battery gets to a certain voltage. Might be possible but I'm not doing it. LOL
