In actual application, as shading from cloud, tree and snow, the panel maybe appear
Multi-MPP, but in actually there is only one real Maximum Power Point. As the below
Figure 1-3 shows:
Figure 1-3 Mutil-MPP Curve
If the program works improperly after appearing Multi-MPP, the system will not work
on the real max power point, which may waste most solar energy resources and
seriously affect the normal operation of the system. The typical MPPT algorithm,
designed by our company, can track the real MPP quickly and accurately, improvethe
utilization rate of the array and avoid the waste of resources.
1.5 Battery Charging Stage
The controller has a 3 stages battery charging algorithm (Bulk Charging, Constant
Charging and Float Charging) for rapid, efficient, and safe battery charging.
