Victron VE.Direct TX Digital Output Cable

Victron VE.Direct TX Digital Output Cable: Intelligent Control for Solar Lighting and Load Management

Expand Your Solar Charger's Capabilities with a Simple Digital Interface

The Victron VE.Direct TX Digital Output Cable unlocks advanced functionality from compatible Victron MPPT solar chargers, enabling precise control of external devices such as LED lighting, energy meters, and virtual load outputs. By connecting directly to the VE.Direct port on your solar charger, this cable provides a reliable digital signal path for automated, energy-efficient system management.

Designed specifically for the BlueSolar MPPT 75/15 and MPPT 100/15 (with software version 1.15 or later), this cable also extends virtual load output capability to larger MPPT models, including the 100/30 and above. It is an essential accessory for installers and system integrators seeking to optimise solar energy utilisation in off-grid, mobile, and remote power applications.

Key Features

• Enables PWM dimming control for compatible LED drivers, reducing energy consumption and extending battery life
• Supports virtual load output on larger MPPT chargers when paired with a BatteryProtect module
• Provides a pulse output for energy meters, transmitting a signal for every 0.01 kWh of solar generation
• Pre-crimped blue insulated ferrule terminals ensure secure, low-resistance connections without soldering
• Integrated strain relief and durable heat-shrink sleeving protect against mechanical stress and environmental wear
• Plug-and-play VE.Direct 4-pin connector with moulded housing for reliable data transmission

Optimised for Solar Lighting Applications

In solar-powered lighting systems, the TX Digital Output Cable allows the MPPT charger to dim LED luminaires based on battery state of charge or programmable schedules. This dynamic control significantly reduces power draw during periods of low solar availability, ensuring critical lighting remains operational even with a partially charged battery. The result is a more resilient system with lower overall energy costs and extended battery service life.

Compatible LED drivers include models from RECOM, Glacial Power, and MEAN WELL, offering flexibility for a wide range of DC lighting designs. The white TX terminal connects to the PWM dimmer input of the LED driver, while the black ground terminal is optional or unused in most configurations.

Virtual Load Output for Larger Systems

For installations using Victron MPPT 100/30 and larger chargers that lack a dedicated load output, this cable provides a virtual load output function. When connected to a Victron BatteryProtect module, the TX signal can disconnect non-critical loads when the battery voltage drops below a user-defined threshold, preventing deep discharge and protecting battery health. This feature is invaluable in unattended off-grid systems where battery longevity is paramount.

Energy Monitoring Integration

The cable can also be configured to send a pulse to an external energy meter each time 0.01 kWh of solar energy is produced. This allows for precise tracking of solar yield without the need for additional current sensors or complex wiring, simplifying system monitoring and performance verification.

Professional-Grade Construction

Every component of the VE.Direct TX Digital Output Cable reflects Victron's commitment to reliability in demanding environments. The pre-crimped bootlace ferrule terminals provide a gas-tight connection that resists vibration and corrosion, while the heat-shrink sleeve at the wire split offers robust strain relief. The 4-pin VE.Direct connector features a moulded housing and integrated cable retention, ensuring consistent signal integrity over years of service.

Compatibility and Configuration

This cable is compatible with BlueSolar and SmartSolar MPPT chargers equipped with a VE.Direct port. The TX port functionality is configured via the VictronConnect app, allowing installers to tailor output behaviour to specific site requirements. Note that older MPPT models (see specifications) are not supported; firmware updates may be required for some units.
