Victron Non-Inverting Remote On-Off Cable: Precision Control for VE.Bus BMS Systems

Seamless Integration with Victron Inverters and MPPT Charge Controllers

The Victron Non-Inverting Remote On-Off Cable provides a reliable, low-power solution for remotely switching compatible Victron inverters and chargers via the load output of an MPPT charge controller. Designed for use with VE.Bus BMS setups, this cable enables automated on/off control based on battery state-of-charge, helping to protect your battery bank from deep discharge without manual intervention.

Unlike generic remote switches, this cable uses an active pull-down logic to ensure a defined off state when the input is floating or below approximately 2V, drawing only ~30mA (short-circuit proof). This prevents unintended operation and enhances system safety in mobile, marine, and off-grid installations.

Engineered for Reliable Low-Voltage Control

With a maximum input and output voltage rating of 70V DC, the cable is suitable for a wide range of 12V, 24V, and 48V nominal systems. The non-inverting logic means the remote on/off state directly follows the control signal—no signal inversion, simplifying integration and troubleshooting.

The cable features a compact signal module encased in protective blue heat shrink, with clearly identified pin terminals for device connection and a single yellow wire for remote switch input. This robust construction resists moisture and vibration, making it ideal for harsh environments.

Key Features

• Non-inverting logic for straightforward control—output state matches input signal
• Active pull-down to switch off when input is floating or below ~2V, preventing accidental activation
• Low current draw (~30mA, short-circuit proof) minimises parasitic load on the system
• Wide voltage compatibility up to 70V DC, suitable for 12V, 24V, and 48V setups
• Pre-terminated pin connectors for quick, secure installation without soldering
• Durable heat-shrink encapsulation protects the logic module from moisture and mechanical stress

Compatibility and Applications

This cable is specifically designed for use with Victron VE.Bus BMS systems and is compatible with all Skylla-TG battery chargers (all models). It also supports legacy Battery Protect models BP40i, BP60i, and BP200i (discontinued). Typical applications include:

• Automated inverter shutdown via MPPT load output to prevent battery over-discharge
• Remote on/off control in caravans, motorhomes, and marine vessels
• Integration into off-grid solar systems for energy management
• Industrial backup power systems requiring remote switching

By using the load output of a Victron MPPT charge controller, you can programmatically disconnect the inverter when the battery voltage drops below a set threshold, preserving battery health and extending cycle life. This is particularly valuable in unattended installations where manual monitoring is impractical.

Installation and Usage Notes

Installation is straightforward: connect the device input terminals to the inverter's remote on/off port, and the yellow control wire to the MPPT load output or a manual switch. The non-inverting behaviour means a high signal (or closed switch) turns the inverter on, while a low signal (or open switch) turns it off. Always refer to the product manual for specific wiring diagrams and ensure all connections are secure.

Note: This cable is not suitable for direct connection to AC mains or high-voltage DC circuits. Maximum ratings must not be exceeded.

Why Choose the Victron Non-Inverting Remote On-Off Cable?

Victron Energy is known for robust, well-engineered power solutions. This cable is no exception—built to the same standards as their inverters and charge controllers, it ensures reliable communication between system components. Using a genuine Victron accessory reduces the risk of compatibility issues and signal interference that can occur with third-party alternatives.

Whether you're upgrading an existing off-grid system or building a new installation, this remote on/off cable offers a simple yet effective way to automate energy management and protect your investment.
