Battery charging voltage and current regulation

How Does a Solar Charge Controller Work?

Modern solar charge controllers work by detecting and monitoring the battery''s voltage level and closely regulating the flow of current from the panels to the battery.

Solar Charge Controller Basics

A charge controller, or charge regulator, is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging.

Battery Charging Stages & Battery Charging Procedure

There are three main stages to charging a battery: constant current, constant voltage, and float charge. Constant current charging is when the charger supplies a set amount of current to the battery, regardless of the voltage. This stage is used to overcome any internal resistance in the battery so that it can be charged as quickly as possible.
