PWM VS MPPT Solar Panel Charge Controller: Which One to Choose?

Are you considering a solar installation on the roof of your van or camper? Then, you will need the right regulator to optimize the charging of your batteries! In this video, I present two types of solar regulators: PWM regulators and MPPT regulators.

Let's start with PWM regulators:

If you are doing your own solar installation, you are less likely to turn to these regulators, except in certain cases. On the other hand, new vehicles, such as campers or vans, are often equipped with PWM regulators because of their affordable cost. Their operation is basic, simply regulating the voltage to recharge the battery.

Let's now move on to MPPT regulators:

These regulators are more sophisticated and efficient. They constantly monitor the voltage of the solar panel to maximize the current. This way, you will fully exploit the power of your solar panels. In addition, MPPT controllers offer advanced charging modes, extending the life of your batteries.

Key differences between PWM and MPPT:

Efficiency: MPPT controllers are much more efficient, with an efficiency of up to 95%.

Voltage: MPPT controllers can accept much higher input voltages than PWM, offering more flexibility.

Charging modes: MPPT offers three charging modes, while PWM only offers two, which can impact the life of the batteries.

Cost: MPPT controllers are more expensive due to their advanced features, but they are a worthwhile investment in the long run.
