The Victron Energy BlueSolar PWM LCD&USB 48-10 is a compact 48V solar charge controller featuring a built-in liquid crystal display, dual USB outputs, and programmable battery charge algorithms for straightforward off-grid solar system management.

Key Features:

• Built-In LCD Display — Onboard liquid crystal display provides real-time status monitoring and full controller setup without additional devices or software.
• Dual 5V USB Outputs — Two built-in USB charging ports deliver up to 2A combined current for convenient device charging directly from the solar system.
• Programmable Battery Charge Algorithm — Pre-programmed charging profiles for AGM, GEL, Flooded, and LiFePO4 batteries ensure optimized charging for all common battery types.
• Day/Night Load Timing — Built-in day/night detection allows a pre-set load ON-time after dusk for automated lighting and load control applications.
• Advanced Overload Protection — Automatically shuts down after 60 seconds at 130% load or after 5 seconds at 160% load, with immediate shutdown on short circuit detection.

The BlueSolar PWM 48-10 supports 48V battery systems with a 100V maximum solar input voltage, delivering 10A of rated charge current for small to mid-size 48V off-grid installations. Its load output with low voltage disconnect, manual control, and timer function provides complete load management in a single unit.

The controller switches to a lower float voltage level two hours after absorption voltage is reached, protecting batteries from overcharge during long sunny periods. A new charge cycle is automatically triggered whenever battery voltage drops below 13V to ensure the battery stays fully topped up.

Built with battery reverse polarity protection, output short circuit protection, and over-temperature protection, this unit is designed for reliable long-term field use. Its IP20-rated enclosure operates across a wide -35°C to +60°C temperature range and meets EN60335-1 and IEC 62109-1 safety standards.
