CN3791 MPPT Solar Panel Voltage Regulator Controller 6V 9V 12V 1 Cell Lithium Battery Charge Solar Panel Charger Board Controller Module
Description:
This is a maximum power poin 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 poin 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.
Features:
Trickle charging of deeply discharged batteries
Automatic recharge
Charge status and charge end status indication
Soft start
Battery overvoltage protection
Solar panel maximum power poin tracking
Complete charge management for single-cell lithium batteries

Find the best size
When comparing your measurements to those listed on the site, make sure to check if the fabric is stretchy or not. If it is, it can stretch an inch or more.
- Bust: Wrap the measuring tape loosely around the fullest part of your bust to ensure a comfortable fit.
- Waist: Measure the narrowest part of your natural waist, holding the measuring tape loose enough to fit comfortably.
- Hips: Drape the measuring tape around the widest part of your hips, resting the tape comfortably against your body.
- Length: For tops and dresses, measure from the top of your shoulder to the hem. For strapless dresses, measure from the highest part of the neckline to the hem. For pants and skirts, measure from the top of the waist to the hem.
- Sleeve: With your arm outstretched, measure from the base of your neck to the end of the sleeve hem to determine where the sleeve length will fall on you.
