Description
xVictron BlueSolar PWM-LCD & USB 12/24V 20A Charge Controller
The Victron BlueSolar PWM-LCD & USB 12/24V-20A is a pulse-width modulation solar charge controller designed for small to medium off-grid solar systems. It suits 12V and 24V battery banks and includes a built-in LCD display and USB output port, making it a practical choice for cabins, caravans, boats and remote installations where simplicity and visibility of charge status matter.
Key Features
- PWM charge regulation for 12V and 24V battery systems, with automatic voltage detection.
- Built-in LCD display shows battery voltage, charge current, solar input and system status at a glance.
- Integrated USB output port allows direct charging of phones, tablets and other USB-powered devices from the solar system.
- 20A maximum charge current supports solar arrays up to approximately 260W (12V) or 520W (24V).
- Compact and lightweight at 0.24 kg, suitable for panel mounting or enclosure installation.
- Compatible with sealed, gel and flooded lead-acid batteries.
- Load output with low-voltage disconnect protects the battery from over-discharge.
Product Overview
PWM charge controllers work by directly connecting the solar panel to the battery once the battery reaches a set voltage threshold, then rapidly switching the connection on and off to maintain the correct charge level. This approach is well-suited to smaller systems where the panel voltage is closely matched to the battery voltage, and where the lower cost and simplicity of PWM is preferable to MPPT technology.
The LCD screen on this unit gives installers and end users a clear read-out of system performance without needing a separate monitor or app. The USB port is a practical addition for off-grid locations where mains power is unavailable. The load output with low-voltage disconnect is particularly useful in unattended installations such as remote monitoring stations or holiday properties, where battery protection is important.
Victron's BlueSolar PWM range is a well-established product line used across the off-grid and leisure sectors. This 20A model covers the most common small system sizes and is straightforward to commission without specialist tools.

Installation Notes
This controller is suitable for installation by a competent person familiar with 12V and 24V DC systems. Ensure the solar panel open-circuit voltage does not exceed the controller's rated input. Connect the battery before connecting the solar panel, and disconnect in reverse order. For installations on boats or vehicles, follow the relevant wiring regulations for the application. This product is not intended for grid-connected systems and does not require G98 or G99 compliance. Use appropriately rated DC fusing and cabling throughout.
