Energy Solutions DC4 SmartSwitch 4 Channel DC Switch Hub

SmartSwitch DC4: Advanced 4 Channel CAN-Controlled DC Switch & Dimmer (12-24V DC, 15A)

Seamless Digital Control for Modern Electrical Systems

Engineered for precision and performance, the SmartSwitch DC4 is a revolutionary 4-channel digital DC switch and dimmer, fully controllable via CAN bus with a single RJ45 VE.Can pinout. Operating on both 12V and 24V systems and delivering up to 15A, this compact module redefines electrical integration for RV, marine, off-grid, caravan, tiny home, and industrial applications.

Transform Your Electrical Control System

SmartSwitch DC4 eliminates outdated manual switches by enabling one-touch control of your DC loads. With seamless integration into Victron Cerbo systems and complete CAN communication capability, it’s a game-changer for smart energy solutions.

• Single-cable connection for simplified wiring
• One-touch control of DC lights or loads
• Multi-mode functionality: On/Off, momentary, dimming
• Integrated load protection: Overcurrent and over-temperature safeguards
• Victron Cerbo compatible and plug & play ready

Flexible and Customisable Channel Features

Each of the 4 independently configurable channels can be set to:

• Switch DC loads on/off (latched)
• Provide dimming through 120Hz PWM
• Act as a digital input for feedback and control

Built-in Safety and Monitoring

Featuring internal power isolation, the DC4 ensures robust operation with enhanced diagnostics:

• Current monitoring up to 30A full scale
• Over-current protection with simulated ATO fuse characteristics (2A, 3A, 4A, 5A)
• Over-temperature protection at module and channel levels
• Output voltage sensing for real-time load and input monitoring

Need to handle higher current than the built-in 15A per channel? No problem. The SmartSwitch DC4 can control high-power loads by using its outputs to drive external relays or contactors. By connecting the DC4 output to a relay coil, you can safely switch larger devices—such as water pumps or heavy lighting—without exceeding the module’s rated limits. This setup retains full CAN control while providing the flexibility to manage higher load currents through properly rated external components.

Future-proof your setup with the potential for upcoming analogue voltage measurement upgrades and advanced digital input capabilities.

Firmware Compatibility Notice

Firmware Requirement: The SmartSwitch DC4 is currently compatible with GX Firmware versions v3.60+. When updating your GX device, please ensure it remains within this firmware range to maintain optimal performance and full feature support for the SmartSwitch.
