Solar regulators, which are also known as solar charge controllers, regulate the solar panel’s charging current to provide the most effective charge to the batteries without overcharging them.
They also prevent the batteries from back feeding into the solar panel at night.
Most “12 volt” panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged.
