Victron document, explaining limits of PWM vs MPPT.

I made an error, presuming that 12V panels into a 12V battery, could be a fair test of an MPPT vs PWM. If you have 24V of panels, the MPPT can make gains against a PWM 12V. The problem is that MPPT is generally "buck" (downwards) DC conversion. They have no "boost", because that would require separate circuitry and another coil. In any case, the EPever states in its back manual specs that it generally loses 5%.
The Jinko solar panel doco draws a diagram of heat max performance.
