Victron Energy - 48V - 10A - BlueSolar PWM-LCD & USB - Solar Charge Controller

Victron BlueSolar PWM-LCD&USB 48V 10A: Intelligent Solar Charge Controller for 48V Off-Grid Systems

Precision Battery Management with LCD Monitoring and Dual USB Charging

The Victron BlueSolar PWM-LCD&USB 48V 10A solar charge controller brings professional-grade battery management to small-scale 48V solar installations. Designed for reliability and ease of use, it features a backlit liquid crystal display for real-time system status and intuitive setup, making it an excellent choice for remote cabins, telecommunications sites, and off-grid backup systems.

Unlike generic PWM controllers, the BlueSolar series incorporates programmable charge algorithms tailored for AGM, GEL, flooded, and LiFePO4 (with internal BMS) batteries. This precision charging helps extend battery service life and reduces the risk of premature capacity loss, a common issue with basic on/off regulators. The controller’s automatic load disconnect safeguards your battery bank from deep discharge, while the day/night timer enables automated lighting control without additional hardware.

Key Features

• Backlit LCD display for clear monitoring of charge status, battery voltage, and load activity
• Programmable charge profiles for AGM, GEL, flooded, and LiFePO4 batteries to optimise charging and longevity
• Low voltage load disconnect with adjustable thresholds prevents harmful over-discharge
• Day/night timer on load output for dusk-to-dawn lighting or timed appliance control
• Dual 5V USB ports (2A total) for convenient device charging directly from the controller
• Comprehensive electronic protection including reverse polarity, short circuit, and over-temperature safeguards
• Common positive grounding simplifies integration with existing systems
• Wide operating temperature range (-35 to +60°C) for reliable performance in harsh environments

Built for Demanding Off-Grid Applications

Engineered to Victron’s exacting standards, this controller handles up to 100V maximum solar input, allowing series connection of two 72-cell panels or four 36-cell panels for a 48V battery bank. The 10A rated charge current supports solar arrays up to approximately 480W, making it suitable for maintaining batteries in seasonal setups, security systems, and small telemetry stations.

The robust terminal block accepts 16 mm² (AWG6) cable, ensuring low-resistance connections and minimal voltage drop. With an IP20 rating, the unit is intended for indoor or protected enclosure mounting, keeping the electronics safe from moisture and dust. Self-consumption is kept below 10 mA, preserving battery charge during periods of low solar input.

Why Choose Victron BlueSolar PWM?

Victron Energy is known for durable, well-engineered power electronics, and the BlueSolar PWM-LCD&USB continues that tradition. The controller’s programmable low voltage disconnect and reconnect voltages give you full control over battery protection, while the manual load override allows direct switching when needed. For installations where an inverter is used, the load output can trigger an inverter’s remote on/off port, automating system operation without complex wiring.

Compared to entry-level PWM controllers, the BlueSolar offers superior build quality, a user-friendly interface, and the flexibility to adapt to different battery chemistries. This reduces the risk of incorrect charging parameters that can lead to battery damage or reduced runtime.

Typical Applications

• 48V off-grid solar systems for remote cabins and sheds
• Telecommunications and monitoring equipment backup
• Solar-powered lighting with automated dusk-to-dawn operation
• Battery maintenance for seasonal or infrequently used installations
• Small-scale renewable energy projects and educational kits

With its compact dimensions (101 x 184 x 47 mm) and lightweight design (0.3 kg), the controller is easy to install in tight spaces. The clear wiring diagram printed on the unit and the intuitive three-button interface reduce setup time and minimise installation errors.
