Product introduction:
The maximum power point tracking (MPPT) of solar cell is to ensure that when the light intensity changes, the photovoltaic cell always outputs the maximum power to make full use of solar energy. In general, switching mode DC-DC converter is needed to realize MPPT ftion to maximize the product (output power) of output and charging . Cn3722 realizes maximum power point tracking ftion of photovoltaic cells by switching buck DC-DC conversion. The maximum input can reach 28V, which is very suitable for applications with large difference between input and battery .
Features of charging management board:
1. High end technology MPPT solar maximum power tracking charging management chip, with trickle , constant , constant charging management
2. It adopts imported high frequency low conduction resistance double MOS transistor, high diode, high efficiency flat high power inductor and alloy detection resistance
3. Large aluminum heat sink at the bottom to ensure long-term stable operation under high
4. High speed and efficient charging mode
5. Dual state indicator light: when the battery is not connected, the red light will flash and the green light will always be on; when charging, the red light will be on, and the green light will be on at the same time when the battery is fully charged
