The Lynx Distribution System

The Lynx Distribution System is a modular busbar system that incorporates DC connections, distribution, fusing, battery monitoring and/or Lithium battery management. For more information also see the DC Distribution Systems product page.

The Lynx Distribution System consist of the following parts:

• Lynx Power In: A positive and negative busbar with 4 connections for batteries or DC equipment.
• Lynx Distributor: A positive and negative busbar with 4 fused connections for batteries or DC equipment together with fuse monitoring.
• Lynx Shunt VE.Can: A positive busbar with a space for a main system fuse and a negative busbar with a shunt for battery monitoring. It has VE. Can communication for monitoring and setup with a GX device.
• Lynx Smart BMS: For use together with Victron Energy Smart Lithium batteries. It contains a positive busbar with a contactor that is driven by a battery management system (BMS) and a negative busbar with a shunt for battery monitoring. It has Bluetooth communication for monitoring and setup via the VictronConnect App and VE.Can communication for monitoring with a GX device and the VRM portal.

System Design

Lynx distribution system parts

A Lynx distribution system usually consists of a single Lynx Shunt VE.Can module or a single Lynx Smart BMS module.

The choice between a Lynx Shunt VE.Can or a Lynx Smart BMS depends on what type of batteries are used in the system. The Lynx Smart BMS can only be used with the Victron Energy Lithium Smart Batteries, while the Lynx Shunt VE.Can is suitable for all other batteries.

Then, single, multiple or a combination of Lynx Distributor modules and/or Lynx Power In modules are added.

Together they form a continuous negative and positive busbar with DC connections and, depending on the configuration, integrated fuses, a battery monitor and/or lithium battery management.

It is also possible to just use Lynx Power In modules and/or Lynx Distributor modules without a Lynx Smart BMS module or a Lynx Shunt VE.Can modules. This for situations where battery monitoring or battery management is not needed.

Interconnecting Lynx modules

Each Lynx module can connect to other Lynx modules on the left side (M8 hole) and on the right side (M8 bolt).

If the Lynx module is the first in line, the last in line or is used by itself, it is possible to connect batteries, loads or chargers directly to these connections. However, we do not generally recommend this because additional insulation and fusing is needed.

Lynx connections: The arrows indicate where the other Lynx modules can connect

The example below shows a Lynx system consisting out of a Lynx Power In, Lynx Shunt VE.Can and Lynx  Distributor. Together they form a continuous busbar, with un-fused battery connections, battery monitor, main system fuse and fused load connections.

Orientation of Lynx modules

If the Lynx System contains a Lynx Shunt VE.Can or Lynx Smart BMS, the batteries always have to be connected to the left side of the Lynx System and the rest of the DC system (loads and chargers) connect to the right side. This, so the battery state of charge can be correctly calculated.

Example of Lynx module orientation: the batteries connect to the left side and all loads and chargers connect on the right side

The Lynx modules can be mounted in any orientation. Should they be mounted upside down, so that the text on the front of the units is upside down as well, use the special stickers are included with each Lynx module, so that the text is orientated the correct way.

Example of Lynx modules mounted upside down: the batteries connect to the right side, all loads and chargers connect to the left side and the upside down stickers are affixed.

System Example – Lynx Power In only

In this system a Lynx Power In is used by itself. Multiple Lynx Power In modules can be connected to each other thus creating a longer busbar with more connections for batteries and/or loads.

The Lynx Power in does not contain fuses. All connected load, chargers or batteries need to be fused externally.

System with a Lynx Power In only

System example – Lynx Shunt VE.Can, Lynx Power In, Lynx Distributor and lead acid batteries

This system contains the following components:

• Lynx Power In with 4 paralleled 12V lead acid batteries.
• Identical cable lengths for each battery.
• Lynx Shunt VE.Can with main system fuse and battery monitor.
• Lynx Distributor with fused connections for inverter/charger(s), loads and chargers. Note that additional modules can be added if more connections are needed.
• CCGX (or other GX device) to read out the battery monitor data.

System sizing

Current rating Lynx modules

The Lynx Distributor, Lynx Shunt VE.Can and the Lynx Power In are rated for a nominal current of 1000A, for 12, 24 or 48 System voltages.

To give an idea of how much power the Lynx modules are rated at different voltages, see below table. The power rating will give you an indication how big the connected inverter/charger system can be. Keep in mind that if inverters or inverter/chargers are used, both the AC and DC system will be powered from the batteries. Also be aware that a Lynx Smart BMS or a Lynx Ion (now discontinued) can have a lower current rating.

Fusing

The Lynx Power In does not have spaces for fuses, fusing needs to be done externally. For more information on fuses and house holders see the Fuses & Fuse holders product page.

Always use fuses with the correct voltage and current rating. Match the fuse rating to the maximum voltages and currents that potentially can occur in the fused circuit. For more information on fuse ratings and fuse current calculations see the Wiring Unlimited book.

 The total value of the fuses of all circuits should not be more than the current rating of the Lynx module, or the Lynx model with the lowest current rating in case of multiple Lynx modules are used.

Cabling

The current rating of the wires or cables used to connect the Lynx Power In to batteries and/or the DC loads has to be rated for the maximum currents that can occur in the connected circuits. Use cabling with a sufficient core surface area to match the maximum current rating of the circuit.

For more information on cabling and cable thickness calculations see the Wiring Unlimited   book.

Mechanical connections

Lynx module connection features

The Lynx module can be opened up by unscrewing 2 cover screws. The contacts on the left side are covered by a removable rubber sleeve. Red is the positive busbar and black is the negative busbar.

Mounting and interconnecting Lynx modules

This paragraph explains how to attach several Lynx modules to each other and how to mount the Lynx assembly into its final location.

For a mechanical drawing of the housing, with dimensions and the location of the mounting holes, see the appendix of this manual.

These are the points to take into consideration when interconnecting and mounting Lynx modules:

• If Lynx modules are going to be connected to the right and if the Lynx module is fitted with a plastic barrier on the right side, remove the black plastic barrier. If the Lynx module is located as the most right module, leave the black plastic barrier in place.
• If Lynx modules are going to be connected to the left, remove the red and black rubber sleeves. If the Lynx module is located as the most left module, leave the red and black rubber sleeves in place.
• If the Lynx system contains a Lynx Smart BMS or Lynx Shunt VE.Can, the left side is the battery side and the right side is the DC system side.
• Connect all Lynx modules to each other using the M8 holes and bolts on the left and right. Take care that the modules correctly slot into the rubber joiner recesses.
• Place the washer, spring washer and nut on the bolts and tighten the bolts using a torque of 14Nm.
• Mount the Lynx assembly in its final location using the 5mm mounting holes.

Electrical connections

Connect DC wires

This chapter might not apply if the Lynx module is connected to other Lynx modules, like can be the case for the Lynx Smart BMS or the Lynx Shunt VE.Can.

For all DC connections the following applies:

• All cables and wires connected to the Lynx module need to have been fitted with M8 cable lugs.
• Pay attention to the correct placement of the cable lug, washer, spring washer and nut on each bolt when attaching the cable to the bolt.
• Tighten the nuts with a torque moment of 14Nm.
