The solar cell maximum power point tracking (MPPT) is to ensure that the photovoltaic cell always outputs the maximum power when the light intensity changes to make full use of solar energy. In general, it is necessary to use a switch-mode DC-DC converter to achieve the MPPT function to keep the product of output voltage and charging current (output power) maximized. CN3722 uses switch-down mode DC-DC conversion to achieve the maximum photovoltaic battery The power point tracking function has an input voltage of up to 28V, which is very suitable for applications where the input voltage and battery voltage are quite different.


Note:

1. Due to the light and screen difference, the item's color may be slightly different from the pictures.

2. Please allow 1-3cm differences due to manual measurement.


Package Included:

1x Solar Charging Controller
