How does a charge controller prevent overcharging?

0

The charge controller monitors the state of charge of the battery (how full it is), and regulates or stops the charging when overcharging begins to occur. The most common way for controllers to determine battery state of charge is by reading battery voltage. The higher the voltage, the higher the state of charge. There are many ways to stop or regulate the charging. A simple method is to just disconnect the solar panel from the battery, with a switch in line between the panel and the battery. This is called a series controller. Another way is to connect solar panel plus to solar panel minus, which just loops the current back to the solar panel instead of to the battery. This is called a shunt controller. A third way is to regulate the output from the solar panel. This means to gradually reduce the amount of current allowed to go to the battery.
