Victron Marine NMEA 2000 Integration Guide

Key Takeaways

• Victron Energy systems integrate with NMEA 2000 networks to display key data on marine Multi-Function Displays (MFDs).
• GX devices act as a central hub, bridging data from various Victron products to the NMEA 2000 network.
• Tank level monitoring, battery status, and AC/DC system data can be viewed on compatible chart plotters.
• Advanced features like wireless AIS and anchor alarms are available through Signal K integration.

What is Victron Marine NMEA 2000 Integration?

Victron Energy offers Marine NMEA2000 Integration to allow Victron products to share data with marine Multi-Function Displays (MFDs) and other NMEA 2000 compatible devices. This integration enables comprehensive monitoring of your vessel's electrical system, including battery, DC, AC system, and tank data, directly on your chart plotter. It streamlines data presentation, providing a unified view of critical information for marine applications.

How Victron Integrates with NMEA 2000 Networks

Victron Energy provides multiple methods for integrating its products with an NMEA 2000 network, primarily through direct VE.Can connections or by using a GX device as a central data bridge.

Direct VE.Can Connection

Certain Victron products equipped with a VE.Can port can connect directly to the NMEA 2000 network. This requires a specific VE.Can to NMEA 2000 cable. Products that support this direct connection include:

• Skylla-i 24V Battery Chargers
• Skylla IP65 Battery Chargers
• Lynx Shunt VE.Can Battery Monitor
• Lynx Smart BMS
• SmartSolar MPPT Solar Chargers with VE.Can communications port
• Multi RS
• Inverter RS

GX Device as a Central Hub

Victron GX devices serve as a central communication gateway, offering robust integration capabilities. They can connect to the NMEA 2000 network and act as a bridge, making data from connected Victron products available to your MFD.

There are two primary methods for MFD integration using a GX device:

1. NMEA 2000 Integration: Connect the GX device directly to the NMEA 2000 network. This method offers customizable data pages on the MFD but typically requires more configuration.
2. HTML5 App Integration: Connect the GX device and MFD via Ethernet. This enables features like Garmin OneHelm or Raymarine LightHouse Apps. This approach is generally plug-and-play with an auto-configured system overview, though it offers less customization.

When enabled, the GX device's NMEA 2000-out function makes data from all connected Battery monitors, Inverter/chargers, and other products available on the NMEA 2000 network.

Key Features and Monitoring Capabilities

Victron's NMEA 2000 integration unlocks a range of monitoring and control features for marine applications.

MFD (Chart Plotter) Monitoring

You can monitor your Victron system data directly on your vessel's Multi-Function Display. This integration is compatible with a wide array of popular marine electronics brands, including Garmin, Raymarine, Furuno, Q Display, and the Navico brands B&G, Simrad, and Lowrance. This allows for a centralized view of your power system alongside navigation and other marine data.

Tank Level Monitoring

Seamlessly integrate tank level data across your NMEA 2000 network, Victron GX devices, and the VRM Portal. The Victron GX devices offer a user-friendly Tank Level Page to centralize and visualize this data. Key features for tank monitoring include:

• Monitoring tank levels on the GX device and VRM Portal.
• Accessing NMEA 2000 tank data or sharing GX tank data with NMEA 2000.
• Customizing tank naming, shapes, and damping for accurate readings.
• Expanding capabilities with the GX Tank 140 module, which supports voltage (0-10V) or current (4-20mA) inputs for various tank senders.

GPS Integration

Victron GX devices can read GPS data, such as location and speed, from the NMEA 2000 network. This allows the GX device to utilize vessel position information. However, it is important to note that GX devices do not output GPS data to the NMEA 2000 network.

Advanced Features with Signal K

For enhanced functionality, Victron's integration with Signal K unlocks powerful features. Signal K is an open data format for marine use, and when utilized with Victron systems, it enables:

• Wireless AIS & Navigation Data: Share NMEA 2000 data via WiFi, allowing marine apps like Navionics to display this information.
• Anchor Alarm: Provides a reliable and easy-to-use alarm system for anchoring.
• Automatic Logbook: Effortlessly tracks your journeys, providing a record of your vessel's movements.

Modbus-TCP for Advanced Systems

For larger vessels or more complex installations, the GX built-in Modbus-TCP server enables SCADA system integration. This feature is ideal for sophisticated monitoring and control systems often found on commercial or larger private yachts.

Deprecated Interfaces

Victron Energy has deprecated the use of both the VE.Bus to NMEA 2000 interface and the VE.Direct to NMEA 2000 interface (specifically for BMV Battery Monitors only). For new installations or upgrades, it is recommended to use a GX device instead, as it provides more comprehensive and integrated functionality.

Safety

Working with marine electrical systems requires careful attention to safety. Always ensure that power sources, including batteries and shore power, are disconnected before performing any wiring or connection work. Use appropriate insulated tools to prevent accidental short circuits, which can cause severe damage or injury. In a marine environment, moisture and corrosion are significant factors; ensure all connections are secure, properly sealed, and protected from the elements to prevent electrical hazards and ensure reliable operation. If you are unsure about any aspect of marine electrical installation, consult a qualified marine electrician.

When to call a technician instead

While Victron's NMEA 2000 integration is designed for user-friendly setup, complex marine electrical systems can present unique challenges. If you encounter persistent communication issues, unexpected data readings, or are unsure about the correct wiring and configuration for your specific vessel, it is advisable to consult a qualified marine electronics technician. Professional assistance ensures proper installation, optimal performance, and adherence to marine electrical standards, which is crucial for safety and reliability at sea.
