Choosing the Correct Solar Battery Charger for Your Solar
Open Circuit Voltage (FOCV) technique. In this method, the solar battery charger input voltage is regulated to a percentage of the open circuit voltage (OCV) of the solar panel. This OCV is the output voltage of the solar panel under a no load condition [ 4]. During normal sunlight conditions this ratio, also known as a K-factor, is

What is the minimum required voltage for charging a 3.7 V Li-ion
Most protection circuits cut off if voltage greater than 4.3 V or temperature greater than 90 °C is reached. Below 2.50 V/cell the battery protection circuit may render the battery unchargeable with regular charging equipment. Most battery circuits stop at 2.7–3.0 V/cell. So to achieve a full state of charge you''d normally want to aim at 4.2V.
