PWM 30-60A controllers
PWM controller 30-60A.
PWM technology is the simplest and consists in using a pulse-width converter at the final stage of battery charging. At the beginning of the charging process, the solar battery is actually connected to the battery. The PWM solar charge controller has a significantly lower cost per ampere, compared to MPPT technology, and has earned such popularity among users by popularity.
The use of PWM controllers makes sense in low-power systems when it is not possible to use more expensive MPT controllers, as well as in regions with high solar activity.
