The Victron Energy BlueSolar PWM Charge Controller (DUO) is a reliable and versatile solution for managing your solar power systems. Designed to operate with 12 or 24-volt DC systems, this 20-amp controller features a clear Liquid Crystal Display (LCD) that provides real-time information on system status, charging process, and battery health. Its dual USB outputs, each providing 5 volts, enable convenient charging of smartphones, tablets, and other USB-powered devices directly from your solar setup.

Equipped with a fully programmable three-stage battery charging algorithm—comprising bulk, absorption, and float stages—the controller ensures optimal battery maintenance and longevity. Its advanced lighting control function allows you to customize lighting schedules and brightness levels, making it suitable for a variety of off-grid applications. The load output includes low voltage disconnect and manual override options, protecting your batteries from deep discharge while providing flexible control over connected loads. The load output is also safeguarded against overloads and short circuits to prevent damage during operation.

Safety features include protection against reverse polarity connections for both solar panels and batteries, reducing the risk of damage due to incorrect wiring. The controller can charge two separate batteries simultaneously, making it ideal for complex solar systems or backup power configurations. An external temperature sensor option helps optimize charging based on ambient conditions, further enhancing battery performance and lifespan. This robust device from Victron Energy is a comprehensive solution for maintaining efficient and safe solar power systems, whether for residential, commercial, or remote installations.
