Description: Trickle charging of deeply discharged batteries. Automatic recharge, Battery overvoltage protection. Charge status and charge end status indication. Solar panel maximum power point tracking. 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 power tracking battery charging circuit and pre-installed four 2-pin JST/PH2.0 connectors. 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. 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). Parameter: Input voltage: 12V Output voltage: nominal 3.7V full charge voltage 4.2V lithium battery Interface: 2-pin JST connectors (or PH2.0) Max Charging current: 2A PWM switching frequency: 300KHz Charging voltage: 4.2V ± 1% Working environment temperature: -40 ° C to +85 ° C Size: 45X20X9.5mm Package included: 1* CN3791 Solar Charge Controller Board 1 Cell Lithium Battery Charge Module

Features

CN3791 Solar Charge Controller Board 1 Cell Lithium Battery Charge Module
This is a maximum power point tracking (MPPT) solar charger for single-cell LiPo batteries.
This MPPT solar charger provide you with the ability to get the most possible power out of your solar panel or other photovoltaic device and into a rechargable LiPo 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, photovoltaic cells output maximum power, to make full use of solar energy.
