MPPT Solar Charge Controller FAQ

  1. What is better MPPT or PWM?

    The main difference between PWM and MPPT charge control devices is that the MPPT devices are more efficient. MPPT charge control devices have 30 % more efficient in charge efficiency according to PWM type.

  2. Can you charge a 12V battery directly from a solar panel?

    20W and 50W solar panels are good for fast charging small 12V batteries. For example, a 20W solar panel can charge a 20Ah 12V battery in around 17 hours of direct sunlight. A 50W panel can do it in around 8 hours. 80W and 100W solar panels are good for fast charging large 12V and car batteries.

  3. How many watts solar do I need to charge a 12V 200Ah battery?
