Product Description

Products Description

Description: 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. 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). 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. Note: If the CN3791 MPPT Solar Charger is 9V version, you must use the Solar panel working Voltage is 9V. Feature: Input voltage: select the corresponding module according to the nominal voltage of the solar panel (6V/9V/12V) Output voltage: nominal 3.7V full charge voltage 4.2V lithium battery Interface: 2-pin JST connectors (or PH2.0) Solar panel maximum power point tracking Complete charge management for single-cell lithium batteries Charging current up to 2A PWM switching frequency: 300KHz Charging voltage: 4.2V ± 1% Trickle charging of deeply discharged batteries Automatic rechargee details of the selling point above, attracting and providing trust to your potential users. Charge status and charge end status indication Soft start Battery overvoltage protection Working environment temperature: -40 ° C to +85 ° C Size: 45X20X9.5mm Package included: 1 x DC 6V 9V 12V CN3791 MPPT Solar Panel Regulator Controller Module for Single-cell LiPo Battery Overvoltage Protection

This 5S BMS board works reliably for my solar battery. The wiring terminals are a bit loose initially, but tightening them properly fixed the minor issue.
