Description
xVictron BlueSolar PWM DUO-LCD&USB 12/24V-20A Solar Charge Controller — SCC010020060
The Victron BlueSolar PWM DUO-LCD&USB is a dual-output PWM solar charge controller designed for 12V and 24V battery systems. It provides up to 20A of charge current and includes a built-in LCD display and USB output port, making it suited to small off-grid installations, caravans, boats and remote power setups where straightforward solar charging and on-board monitoring are required.
Key Features
- Dual battery output (DUO) allows simultaneous charging of two separate battery banks from a single solar input.
- Compatible with 12V and 24V battery systems, with automatic voltage detection.
- 20A maximum charge current supports a range of small to mid-size solar panel configurations.
- Built-in LCD display shows real-time system data including battery voltage, charge current and charge state.
- Integrated USB port provides a 5V output for charging phones, tablets or other USB-powered devices directly from the solar system.
- PWM (Pulse Width Modulation) charge algorithm extends battery life by reducing stress during the absorption and float phases.
- Compact and lightweight at 0.377kg, suitable for space-constrained installations.
Product Overview
PWM charge controllers regulate the current flowing from the solar panel to the battery by switching the connection on and off at high frequency. As the battery approaches full charge, the controller reduces the average current delivered, preventing overcharge without the complexity of MPPT tracking circuitry. This makes PWM controllers a cost-effective choice for smaller systems where the panel voltage is closely matched to the battery voltage.
The DUO variant adds a second battery output, which is particularly useful on boats or campervans where a starter battery and a leisure battery need to be maintained separately. The primary bank charges first; once it reaches a set threshold, the controller diverts charge to the secondary bank. This prevents the secondary bank from drawing down the primary.
The LCD display gives installers and end users immediate visibility of system status without needing a separate monitor or app. The USB port is a practical addition for mobile and remote installations where mains power is unavailable.

Installation Notes
This controller is intended for 12V and 24V off-grid battery systems only and is not suitable for grid-connected installations. Ensure the solar panel open-circuit voltage does not exceed the controller's rated input. For dual battery bank wiring, follow Victron's published wiring guidance to ensure correct sequencing of charge between primary and secondary banks. Installation should be carried out by a competent person familiar with low-voltage DC electrical systems. Fuse both the battery and solar connections close to the source as per standard DC wiring practice.
