PWM Controllers 30-60A
PWM technology is more simple and is to use a pulse-width converter in the final stage of charging the battery. At the beginning of the charging process, the solar battery is actually connected directly to the battery. The solar charge controller PWM has a significantly lower cost per amp, compared to MPPT technology, and therefore deserved such popularity among users.
The use of PWM controllers makes sense in low-power systems where it is not possible to use a more expensive MPPT controller, as well as in regions with high solar activity.
