Battery Charging Stage - Epever iTracer-ND Series User Manual

Figure 1-2 Maximum Power Point Curve
The panel may appear Multi-MPP as shading from cloud, tree, or snow in
actual application. However, there is only one real Maximum Power Point. As
the Figure 1-3 show:
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. It may waste most solar energy resources
and affect the system's normal operation. The typical MPPT algorithm,
designed by our company, can track the real MPP quickly and accurately,
improve the array's utilization rate and avoid wasting resources.

1.5 Battery Charging Stage

The controller has a three-stage battery charging algorithm (Bulk Charging,
Constant Charging, and Float Charging) for rapid, efficient, and safe battery
charging.
