1:Pulse Width Modulation (PWM) Technology: Function: PWM technology regulates the charging process by rapidly switching the connection between the solar panel and the battery. This helps maintain the optimal charging voltage and current, ensuring efficient and safe battery charging. Efficiency: While not as efficient as MPPT controllers, PWM controllers are cost-effective and suitable for smaller systems. 2:Overcharge Protection: Function: Automatically stops charging when the battery reaches full capacity to prevent overcharging and potential damage. Threshold: Typically set to 14.4V for 12V lead-acid batteries. 3:Overdischarge Protection: Function: Disconnects the load when the battery voltage drops below a certain threshold to prevent deep discharge and extend battery life. Threshold: Typically set to 10.5V for 12V lead-acid batteries. 4:Reverse Current Protection: Function: Prevents current from flowing back from the battery to the solar panel at night, which can drain the battery. A 12V 10A PWM (Pulse Width Modulation) solar charge controller is designed to manage the charging of 12V batteries from solar panels. It is ideal for small to medium-sized off-grid solar power systems, such as those used in RVs, boats, cabins, and small home systems. The controller ensures that the battery is charged efficiently and safely while protecting it from overcharging, overdischarging, and other potential issues.
