Description
xVictron BlueSolar PWM-LCD&USB 48V-20A Charge Controller
The Victron BlueSolar PWM-LCD&USB 48V-20A is a pulse-width modulation solar charge controller designed for 48V battery systems. It suits off-grid installations where a clear on-device display and USB charging output are practical requirements. The built-in LCD gives installers and end users direct visibility of system status without needing a separate monitor.
Key Features
- 48V system voltage with a 20A charge current rating, suitable for small to medium off-grid arrays.
- LCD display shows battery voltage, solar input, charge current and charge state directly on the unit.
- Integrated USB output port allows low-power device charging from the solar system.
- PWM charge algorithm extends battery life by reducing overcharge stress during the float stage.
- Compatible with sealed, gel and flooded lead-acid batteries.
- Compact and lightweight at 0.3 kg, suitable for panel-mounting in enclosures or on DIN rail with an adapter.
Product Overview
PWM controllers work by connecting the solar panel directly to the battery once the bulk charge threshold is reached, then rapidly switching the connection on and off to maintain the target voltage. This approach is straightforward and cost-effective for smaller systems where the panel voltage is closely matched to the battery bank voltage. The 48V rating makes this unit appropriate for larger off-grid battery banks where a higher nominal voltage reduces cable losses.
The LCD on this unit removes the need for a separate battery monitor or app to check basic system status. Charge current, battery voltage and charge stage are all readable at a glance. The USB port is a practical addition for sites where small devices such as phones or radios need charging without a separate inverter. This is not a Bluetooth or VE.Direct connected device, so remote monitoring via the Victron ecosystem is not available on this model.

Installation Notes
This controller is intended for 48V nominal battery systems only. Connecting it to a battery bank of a different voltage will damage the unit. Ensure the solar panel open-circuit voltage does not exceed the controller's rated input. Installation should be carried out by a qualified electrician or experienced solar installer. For any grid-connected or larger off-grid systems, consult a professional familiar with current UK wiring regulations.
