Electric circuits can become complex when multiple components are involved, such as in a solar power system. To protect the system and ensure efficient operation, solar charge controllers are essential. There are various types of solar charge controllers available, including series regulators, shunt regulators, pulse width modulation (PWM) controllers, and maximum power point tracking (MPPT) controllers.
