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, improve the 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.
