PWM vs MPPT Solar Charge Controllers
The charge controller is a key component of a solar power system and specifying the best one for the system requires some analysis. Below is a quick overview.
What’s the Difference?
The two types of charge controllers most commonly used in today’s solar power systems are pulse width modulation (PWM) and maximum power point tracking (MPPT).
