It does this by increasing the applied current to maintain the power. On the other hand, the MPPT solar charge controller will maintain the power at 17×4 = 68 watts. This gives you an applied power of 13×4 = 52 Watts. The PWM charge controller will maintain the current it receives and operate at about 13 volts. And you want to charge a 12 volts battery. Let’s say you have a PWM charge controller and a solar panel that is producing 17 volts and about 4A of current. The MMPT charge controller is a more efficient charge controller because it converts higher voltages to current so that you can have more power being applied to your batteries. You could easily buy an extra solar panel for the cost of upgrading to the MPPT controller. What is the difference between the PWM charge controller and the MPPT charge controller?įor starters, the MPPT charge controller is way more expensive than the PWM charge controller. These options cost a few hundred dollars more. The default choice for the Starter kit on Amazon is the 30 A PWM solar charge controller, but there are options for the 20A MPPT charge controller or 40 A MPPT charge controller.
