Solar cell maximum power point tracking (MPPT)

Solar cell maximum power point tracking (MPPT) is to ensure that the light intensity changes, the photovoltaic cells have been the maximum output power to take full advantage of solar energy. In general, it is necessary to use the switch mode DC-DC converter to achieve MPPT function, to maintain the output voltage and charge current product (output power) to maximize.

CN3722 is the use of switching buck mode DC-DC conversion way to achieve the maximum power point tracking function of photovoltaic cells, the input voltage up to 25V, very suitable for input voltage and battery voltage difference between the relatively large applications.

Charge management board features: best-for-sell

1. High-end technology MPPT solar maximum power tracking charge management chip, with trickle, constant current, constant voltage charging management

2. The use of imported high-frequency low-conduction resistance double MOS tube, high current diode, high efficiency flat high-power inductors, Kang copper current detection resistor

3. The bottom of the large aluminum heat sink, to ensure a long time to stabilize the work of large current.

4. High-speed and efficient charging method.

5. Dual status indicator, no battery when the red light flashes green light is always on, charging red light, full of self-stop while the green light.
