Description
Victron Energy SCC010020020 BlueSolar PWM-Light 12/24V 20A Charge Controller
Overview
The Victron BlueSolar PWM-Light 20A (SCC010020020) is a reliable, budget-conscious charge controller built for 12V and 24V off-grid battery systems. It features automatic system voltage detection, three-stage battery charging, and intuitive load output control with low-voltage disconnect.
With its compact size and rugged simplicity, this model is ideal for off-grid lighting, RV and van builds, backup battery maintenance, and small solar systems where PWM efficiency is sufficient.
Key Features
- Automatic 12V/24V Detection: Adapts instantly to your battery system without manual configuration.
- 20A Charge Current: Supports medium-size solar arrays for lighting, DC appliances, and battery charging.
- Three-Stage Battery Charging: Built-in bulk, absorption, and float stages help extend battery life.
- Low Voltage Disconnect (LVD): Protects battery life by disconnecting loads at safe voltage thresholds.
- Basic Lighting Control Function: Includes programmable on/off timing for nighttime operation.
- Onboard Display: Two-digit LED readout for fast, intuitive setup and timer adjustment.
- System Protections: Includes overload, reverse polarity, short circuit, and thermal shutdown safeguards.
- Common Positive Ground: Streamlines system wiring and compatibility.
