This is a maximum power tracking (MPPT) solar charger for single-cell lithium polymer batteries. This MPPT solar charger enables you to the maximum possible power from solar panels or other photovoltaic devices and put it in a rechargeable lithium polymer battery.
The setup is also simple, just plug the solar panel into one side of the solar charger and the battery into the other side to charging! Solar Maximum Power Tracking (MPPT) is to that the light intensity changes, the photovoltaic cell outputs the maximum power, and makes full use of solar energy.
Under normal circumstances, a switch-mode DC-DC converter is required to realize the MPPT function, the product of output voltage and charging current maximized (output).
The output of the solar charger is designed to charge a single polymer lithium- battery. The load should be connected in parallel with the battery. Each solar charger is equipped with a CN3791 power tracking battery charging circuit, and is -installed with four 2-pin JST/PH2.0 connectors. This is a super mini Solar Powered LED Driver based on the CN3163 and CN5711. You can use this board DIY a solar street light, solar LED and so on.
CN5711 is a current modulation integrated circuit with a constant output current of up to 1A, which can be used to drive types of light-emitting diodes including white light-emitting diodes.
This CN3163 Solar charger you with the to the most possible power out of your solar panel or other photovoltaic device and into a rechargable battery. Set-up is easy as , just plug your solar panel into one side of the Solar charger and your battery into the other and you are good to charging!
