CN3791 MPPT 3.7V 4.2V Lithium Battery Charging Module

Description This is a maximum point tracking (MPPT) solar charger for single-cell batteries. This MPPT solar charger provides you with the ability to get the most possible out of your solar panel or other photovoltaic device and into a rechargeable 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 point tracking (MPPT) is to that the light intensity change, photovoltaic cells output maximum , to make full use of solar energy. Features: Trickle charging of deeply discharged batteries. Automatic recharge, Battery overvoltage protection. Charge status and charge end status indication. Complete charge management for single-cell lithium batteries. 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 tracking battery charging circuit and pre-installed four 2-pin JST/PH2.0 connectors. Default we have set the holding voltage for MPPT. 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).
