Solar voltage control device 60 A

PWM technology is simpler and involves the use of a pulse-width converter in the final stage of battery charging. At the beginning of the charging process, the solar battery is actually connected directly to the battery. The PWM solar charge controller has a much lower cost per amp compared to MPPT technology, and therefore has earned such popularity among users.

The use of PWM controllers makes sense in low power systems when it is not possible to use a more expensive MPPT controller, as well as in regions with high solar activity.
