Victron Energy BlueSolar PWM-LCD&USB 48V-20A Charge Controllers SCC040020050

The Victron Energy SCC040020050 BlueSolar PWM-LCD&USB 48V-20A is a PWM solar charge controller designed for 48V battery systems, combining a 20A rated charging current with an integrated LCD display, programmable load output, and dual USB outputs. The LCD provides convenient system status monitoring and controller setup directly at the unit.

The controller supports programmable charging profiles for AGM, GEL, flooded lead-acid, and LiFePO4 batteries with an internal BMS. It also provides automatic low-voltage load disconnection, adjustable load control, and day/night timing for applications where connected DC loads need to operate according to battery condition or daylight cycle.

Key Technology

• 48V PWM Solar Charging
  Designed specifically for 48V battery systems with a 20A rated charging current and PWM charging control.

• Integrated LCD Display
  Features a built-in liquid crystal display for convenient status monitoring and controller setup directly from the device. 

• Programmable Battery Charging
  Provides preprogrammed charging algorithms for AGM, GEL, flooded, and LiFePO4 batteries equipped with an internal BMS. 

• Automatic Low-Voltage Load Disconnect
  The load output can automatically disconnect connected loads when battery voltage falls to the configured threshold, helping prevent excessive battery discharge.

• Programmable Load Output
  Supports manual load control, low-voltage disconnect, and timer functionality, allowing the controller to manage compatible DC loads according to system requirements. 

• Day/Night Timer
  The load output can be configured for a preset ON period after dusk, making the controller useful for compatible lighting and other time-controlled DC loads.

• Dual USB Outputs
  Provides two 5V USB outputs with a 2A maximum combined output current for powering or charging compatible USB devices. 

• Integrated Electrical Protection
  Includes protection for battery reverse polarity, output short circuit, overtemperature, and load overload conditions.

Best Uses

• 48V Battery-Based Solar Systems
  Designed for photovoltaic charging applications built around a compatible 48V battery bank.

• Off-Grid Solar Systems
  Suitable for standalone solar installations where straightforward PWM charging, local system monitoring, and load management are required.

• Solar Lighting Systems
  The programmable day/night timer can automatically operate compatible lighting loads for a preset period after dusk.

• DC Load Management
  Useful where compatible DC loads need automatic low-voltage disconnection to reduce the risk of excessive battery discharge.

• Local System Monitoring
  The integrated LCD makes the controller well suited to installations where charging information and setup controls need to be available directly at the system.

• Multiple Battery Chemistries
  Supports configurable charging for compatible AGM, GEL, flooded, and internally managed LiFePO4 battery systems.
