• The function, “153 Inverter”, represents the AC-output
• The function “154 AC Input” monitor represents the AC-input
Charger status messages will be sent by the Inverter function. Both functions have their own network address. Since both
functions transmit the same PGNs, for example an AC Status PGN containing voltage, current and more information, NMEA 2000
data consumers like generic displays will need to be able to make a distinction based on the network address. Depending on the
function belonging to that network address, the need to interpret it as either Inverter Input or Inverter Output.
• Displays not being capable of doing so will regard the data as belonging to the mains (utility). The Inverter Output is then
interpreted as utility #0 and Inverter Input as utility #1. These default instance numbers can be changed by a network
configuration tool if necessary.
• Battery temperature, as measured by the inverter(/charger), is transmitted as well.
• All VREG communications need to be sent to the address representing the Inverter function. The other one, AC input, does not
support VREG requests: that address only transmits AC information related to the AC input.
Inverters
• Both, the range of inverters connected via VE.Bus as well as our range of inverters connected using a VE.Direct cable, is
supported and its information made available on the NMEA 2000 network.
Battery monitors
• Supported. This includes any battery monitor as supported by the GX device.
• The battery selected as the system battery in the GX device (Settings → System Setup → Battery Monitor) are transmitted
with a fixed Device and Battery instance of 239, this to ensure there is always the same instance for the main (system)
battery instead of a system using instance 0 for i.e the Lynx Smart BMS (with built-in battery monitor) and a system with ie. a
SmartShunt using different instances.
Solar chargers
• Supported. Battery related values as well as the PV Array Voltage & Current is made available on the NMEA 2000 network.
AC chargers
• Phoenix Smart IP43 Charger 120-240V and 230V models are supported. Only the 120-240V model allows to be remotely
controlled (on/off and input current limit) from a compatible MFD.
Tank level data
• All tank levels visible on the GX device, including GX Tank 140 and Mopeka sensors, are transmitted onto the NMEA 2000
network. The used PGN is 127505 Fluid Level, which includes Fluid instance (aka Data instance), Fluid type (Fuel, Fresh
Water, Waste Water, Live Well, Oil, Black Water, Gadoline, Diesel, LPG, LNG, Hydraulic oil and Raw Water) and Fluid level as
percentage of tank capacity and tank capacity.
Be careful when using the fluid types LNG, LPG, Diesel and Hydraulic oil: these are relatively new types in the NMEA 2000
standard and not all MFDs and chartplotters support them yet.
• Labelling of the tanks on the MFDs needs to be done on each MFD itself. The custom name as configured in the Victron
system is transmitted in the field Installation description #1 in the PGN 126996 - Product Information, but not used by the
MFDs.
• The GX device automatically numbers each tank with a unique Device instance and Tank instance. They are made the same.
This automatic numbering is done specifically and only for tank levels to make the process of showing them properly on all
different brands and types of MFDs as simply as possible.
Other data and product types
• Not supported. Above explicitly mentioned types are the only ones now supported.
