Victron Lynx Shunt VE.Can: Setup and Specs

The Victron Lynx Shunt VE.Can is a battery monitor built into a Lynx busbar module. It combines a positive busbar with a main fuse holder and a negative busbar with a 1000A shunt, and reports to a GX device over VE.Can. It slots into the Lynx Distribution system next to a Lynx Power In or Lynx Distributor. Here’s what Victron’s datasheet says.

Reverse polarity protection: none, according to the datasheet, so double-check polarity before connecting.

Features

Busbar-integrated monitoring: state of charge, current and voltage without a separate shunt.
Main fuse holder inside the module. A dummy busbar is included, so you can move the main fuse elsewhere when a larger fuse is needed.
Powers a Lynx Distributor’s fuse monitoring LEDs through RJ10 cables.
Potential-free alarm relay.

The GX Requirement

The Lynx Shunt has no Bluetooth or display of its own. Victron says it communicates with GX devices via VE.Can, so you’ll need a Cerbo GX, Ekrano GX or similar, with a GX Touch, Remote Console or VRM to read it and set it up.

Lynx Shunt VE.Can vs SmartShunt

	Lynx Shunt VE.Can	SmartShunt
Rating	1000A	300A, 500A, 1000A or 2000A
Interface	VE.Can (GX needed)	Bluetooth + VE.Direct
Main fuse	Built in	Separate
Fits Lynx busbar	Yes	No

Setup

Use the included RJ45 terminators at each end of the VE.Can chain. Then set battery capacity and charged parameters from the GX device, as with other Victron monitors.

Who It’s For

Lynx-based systems with a Cerbo GX, on boats, big RVs and off-grid cabins.
Builders who want a clean busbar layout with fewer cables.

Good to Know Before You Buy

GX device required.
No reverse polarity protection.
If you use a Lynx Smart BMS, you may not need it: Victron says that BMS already has its own shunt in the negative busbar.

Where the Lynx Shunt VE.Can Sits in a Lynx System

Lynx modules bolt together side by side, so the order matters. A typical layout, from the battery outward:

Battery bank positive and negative cables land on the Lynx Shunt VE.Can.
Lynx Shunt VE.Can: main fuse on the positive busbar, 1000A shunt on the negative busbar.
Lynx Distributor: individual MEGA fuses for the inverter-charger, the solar charger, a DC-DC charger and the DC panel.
Cerbo GX or Ekrano GX: connected by a VE.Can cable, with a terminator at each end of the chain.

Because every load and charger connects after the shunt, it measures everything that flows in or out of the battery.

Worked Example: Headroom on a 1000A Rating

Load	12V current (estimate)	24V current (estimate)	48V current (estimate)
3,000W inverter	≈ 270A	≈ 135A	≈ 67A
5,000W inverter	≈ 450A	≈ 225A	≈ 112A
8,000W (two inverters)	≈ 720A	≈ 360A	≈ 180A

Estimates: watts ÷ battery voltage ÷ about 93% efficiency.

Even a large 12V system sits well inside the 1000A continuous rating. The main fuse, not the shunt, is usually the limit, which is why the module includes a dummy busbar for moving the fuse to a separate, larger holder.

Worked Example: Self-Consumption

The datasheet lists power consumption of 60mA at 12V, 33mA at 24V and 20mA at 48V. Over a month:

12V: 0.06A × 24h × 30 days ≈ 43Ah
24V: 0.033A × 720h ≈ 24Ah
48V: 0.02A × 720h ≈ 14Ah

Worked estimates. For long-term storage, switch the system off at the main disconnect to keep the battery from slowly draining.

Setup Step by Step

Check polarity twice. The datasheet lists no reverse polarity protection.
Fit the main fuse (CNN, ANL or MEGA, sized for your battery cable) or the dummy busbar if the fuse is mounted elsewhere.
Connect the battery cables, then the neighboring Lynx modules.
Run the VE.Can cable to the GX device, with the included RJ45 terminators at each end of the chain.
Fit the included temperature sensor at the battery, as shown in the manual.
On the GX device, open the Lynx Shunt’s settings and enter the battery capacity, charged voltage and tail current from your battery’s datasheet.
Let the battery fully charge once so the shunt synchronizes to 100%.

Using the Alarm Relay

The potential-free relay is rated 3A at 30V DC or 250V AC. A common use is switching on a buzzer or warning light at a low state of charge. Set the trigger levels from the GX device.

Reading the Data on a GX Device and VRM

Once it’s set up, the GX device shows battery voltage, current, power, state of charge, consumed amp-hours and time-to-go. Through the free VRM portal you can check the same figures remotely and look back at history such as the deepest discharge and the number of charge cycles. That history is handy for spotting a slow parasitic load or confirming that solar is keeping up.

FAQ

Does the Victron Lynx Shunt VE.Can have Bluetooth?

No. It talks to a GX device over VE.Can.

What fuse goes in it?

A CNN, ANL or MEGA fuse, bought separately and sized per the manual.

Can I use the Lynx Shunt VE.Can with a 48V battery?

Yes. It covers 12, 24 and 48V systems, with a supply range of 9–70V DC.

Do I still need a SmartShunt?

No. The Lynx Shunt is the battery monitor, so one shunt per battery bank is enough.

Does it need a GX device for setup?

Yes. It has no display or Bluetooth, so you configure and read it through a GX device, Remote Console or VRM.
