19. Shade Tolerant MPPT Algorithm
An ability to harvest the maximum amount of energy from a PV array is one of the small number of critical features a PV inverter can offer to optimise return on a PV system investment (ROI)
Partially shaded arrays can introduce significant challenges when optimising harvest energy
Energy harvest is maximized at the V-I point of inflection, for traditional MPPT trackers this coincides at the local maxima at the highest array voltage 19

20. Shade Tolerant MPPT Algorithm
Schneider Electric’s Shade-Tolerant Fast SweepTM MPPT Algorithm harvests maximum possible power at “Global Maximum,” unlike Traditional MPPT algorithms that track “Localized Power Bump”
The Shade Tolerate Algorithm for string inverters can even result in higher energy yield than micro inverters in many common situations of shade.*

24. with different orientation roofs (East-West)
Supports Arrays on Roofs with Different Orientations
Due to the different orientations, the East and West facing solar modules are exposed to different irradiation levels throughout the day
As a result their PV outputs are different throughout the day
This leads to array mismatching and sub-optimal PV system performance
Conext RL dual MPPT inverter is the right choice to handle such scenario
