Our MPPT algorithm, custom-designed by our company, can track the real MPP
quickly and accurately, improve the utilization rate of the solar 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.
Figure 1-4 Battery changing stage Curve
A) Bulk Charging:
In this stage, the battery voltage has not yet reached constant voltage (Equalize
or Boost Voltage), the controller operates in constant current mode, delivering its
maximum current to the batteries (MPPT Charging).
B) Constant Charging:
When the battery voltage reaches the constant voltage setpoint, the controller
will start to operate in constant charging mode, no longer using the full MPPT
output. The Constant Charging mode has 2 stages, equalize and boost. These
two stages are not carried out constantly in the full charge process to avoid
excessive gas production or overheating of battery.
