Move batts inside trailer worth it? mppt controller rec

mppt may offer about 10% improvement of output in the real world. It is better to use 24 or higher voltage with mppt.

It is cheaper and better to add a 2nd panel than to spend funds on a top of the line mppt.

In my opinion, charge controllers need to include a battery temperature sensor. They ought to have adjustable voltage set points.

The time to switch to MPPT is when you are contemplating 600 watts or more of panels, or if there is no more room to add panels.
