Solar Maximum Power Point Tracking Theory

MPPT (Maximum Power Point Tracking)
Through the MPPT your solar modules operate always with optimized efficiency.
The result is most destinct in winter and bad weather seasons. It could be up to 35% more charge current just then, when the current is most urgently needed.
The diagram shows the devolution in Ah during a winter day from 8:24 a.m. till 4 o'clock p.m. with a MPP-charger from Schams-Electronic and for comparison without a charge controller.
Your solar installation is as good, as it is during the worst season. Then MPP-charge controllers unfold their best advantage.

MPPT-Theorie Wind turbine Maximum Power Point Tracking Theory

As a further consequent step, we have developed windpower charge controllers, which increase the income of a offgrid wind power station for around 100%.
In offgrid wind power stations the advantage is even more considerable. Because of the rise of the Generator voltage at strong wind, to more than 100% above the battery voltage, the income due to MPPT is also about 100% higher as without MPPT.
The diagram (on the left) shows like the charge current (red) behaves, when the windgenerator works in the optimum (purple) working point. Immediately the current rises for more than double of the value before.
