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.
A connected inverter changes the DC electricity received from the solar panels into the AC (alternating current) electricity needed for EV charging. The AC electricity goes to a distribution board to be used by power devices, and any surplus electricity is stored in a battery or fed to the grid for use by others.

The solar battery charging basics include monitoring the SOC to gauge battery capacity, understanding deep cycle batteries, using charge controllers or other storage devices, and preventing overcharging.
A charge controller adjusts the current and volts coming from the solar panel and delivers safe power to the battery. It ensures safe and efficient charging. When it comes to charge controllers, there are two specifications: max voltage and amp rating. Like solar panels, charge controllers have a nominal voltage rating like 12V and 24V.
MPPT charge controllers regulate the voltage and the current from the solar array to match the requirements of a charging battery and consequently protect it. The main advantage of MPPT charge controllers is that while protecting the battery, they manage to optimize the output power of the solar array and minimize energy losses.
