The blue area in the above graph (ΔP) represents the typical operating area of a traditional PWM
type solar charge controller. As you can see, Pmax (MPPT) is higher than ΔP (PWM).
The fast and efficient MPPT technology onboard of the Omnicharge Solar products makes sure that
the maximum power point is tracked continuously. This is to make sure that it always operates at the
maximum power point of the PV array, that may vary continuously against irradiation levels from the
sun, partial shading (causing more than one Pmax point) and last but not least PV array temperature.
In general, a well designed MPPT solar charge controller will typically get 15 – 25% more power from
your PV array compared to traditional PWM type solar chargers.
