BlueSolar PWM DUO-LCD-USB 12V|24V|20A manual introduces features and characteristics of the product, including three-stage charging, external temperature sensor, 2 battery outputs, battery type, reverse polarity connection, USB output, temperature protection, etc.
The Victron Energy BlueSolar PWM DUO 12V|24V|20A LCD-USB series is a solar charge controller that uses Pulse Width Modulation (PWM) combined with a multistage charge control algorithm. It features a filtered PWM power control system using highly efficient MOSFET transistors to ensure superior charging and enhanced battery performance. The device supports three-stage battery charging (bulk, absorption, and float) and includes an external temperature sensor for optimized charging profiles.
