PWM Charge Controller (Pulse Width Modulation) is a reliable device used in solar power systems to regulate the charging process between solar panels and batteries. It prevents overcharging, ensuring stable and efficient power flow, and is commonly used in off-grid and small-scale solar systems. PWM controllers are cost-effective and ideal for 12V or 24V battery systems.
