PWM charging controller 20A

Prevents the solar panels from overcharging the battery. With the USB connector, you can conveniently charge phones and smart devices. The charging operation of the PWM controllers is managed with the help of a microprocessor, where the device's intelligent pulse width modulation (PWM) achieves significant advantages in terms of the charging result. When the battery is full, the charging is not completely stopped (as happens in controllers operating on the charging relay principle), but charging is continued all the time by continuously pulsing the charging current to the battery, so that especially an aged battery is charged. The PWM controller therefore provides a clearly better charging result than a controller operating on the charging relay principle.

Includes outputs for batteries and a separate load.

You can connect panels totaling 260W (12V system) or 480W (24V system) to this controller.
