How efficient is a solar charge controller?

The tracking efficiency is pretty good. Not all the power getting to a solar charge controller from a solar panel array is used in charging batteries. Some of it is lost as heat. Consequently, the output power of a charge controller to the battery is always less than the input power it receives from the solar panels.

What batteries can a solar charge controller charge?
