Description:
1.This is a maximum power point tracking (MPPT) solar charger for single-cell     batteries. This MPPT solar charger provide you with the ability to get the most possible power out of your solar panel or other photo voltaic device and into a battery. Set-up is easy as well, just plug your solar panel into one side of the solar charger and your battery into the other and you are good to start charging!

Solar maximum power point tracking (MPPT) is to ensure that the light intensity change, photo voltaic cells output maximum power, to make full use of solar energy. In general, need to use a switch mode DC – DC converter to realize MPPT function, keep the output voltage and charging current product maximize (output).

2.The output of the Solar Charger is intended to charge a single polymer lithium ion cell. The load should be connected in parallel with the battery. Each Solar Charger comes equipped with a CN3791 power tracking battery charging circuit and four 2-pin JST/PH2.0 connectors.

3.Default we have set the holding voltage for MPPT. So we have 3 version for the input voltage 6V/9V/12V(for Solar Panel working voltage 6V/9V/12V), very suitable for the application of the input voltage and battery voltage difference is bigger.
