Victron Energy BlueSolar PWM-Pro Charge Controller 12V/24V 20A

The BlueSolar PWM-Pro series is ready to use with its default settings but is also fully programmable. It features a fully programmable lighting control function, three-stage battery charging (bulk, absorption, float), an integrated battery monitor function (Remote Panel needed to display the state of charge), load output with low voltage disconnect and manual control (default setting), and an optional external temperature sensor. The load output is protected against overload and short circuit, and the system is protected against reverse polarity connection of the solar panels and/or battery. It also includes day/night timing options (see manual Remote Panel for details). The BlueSolar PWM-Light features a load output with low battery voltage disconnect function, a lighting control function with one timer, and a two-digit seven-segment display for quick and easy setting of the load output functionality, including timer setting. It also has three-stage battery charging (bulk, absorption, float) that is not programmable, load output protected against overload and short circuit, protection against reverse polarity connection of the solar array and/or battery, and day/night timing options.
