System Design
Lynx distribution system parts
A Lynx distribution system usually consists of a single Lynx Smart BMS module together with a Lynx Class-T Power, Lynx Power In, or Lynx Distributor. Note that the Lynx Shunt VE. Can is only available with M8 connections and therefore cannot be connected directly to the Lynx Class-T Power, which has M10 connections. Then, single, multiple,e or a combination of Lynx Distributor modules and/or Lynx Power In/Lynx Class-T 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,r and/or lithium battery management. It is also possible to use Lynx Power In/Lynx Class-T Power In modules and/or Lynx Distributor modules without a Lynx Smart. BMS module. This is for situations where battery monitoring or battery management is not needed.
Interconnecting Lynx modules
Each Lynx module can be connected to other Lynx modules on the left and right. Note that M10 modules cannot be connected directly to M8 modules and vice versa. If the Lynx module is the first in line, the last in line,e or is used by itself, it is possible to connect batteries, loads, or chargers directly to these connections. Please note that additional fusing may be required if batteries and loads are connected directly to the interconnections.
The example below shows a Lynx system consisting of a Lynx Class-T Power In, Lynx Smart, BMS, and a Lynx Distributor. Together, they form a continuous busbar with fused battery and load connections, battery monitor, BMS sy, stem, and contactor. Interconnected Lynx modules: Lynx Class-T Power In, Lynx Smar,t BMS, and a Lynx Distributor.
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 Syste,m, and the rest of the DC system (loads and chargers) connect to the right side. This s so the battery state of
charge can be correctly calculated. 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 included with each Lynx module so that the text is orientated correctly
System Example – Lynx Class-T Power In and Lynx Distributor
This system uses a Lynx Class-T Power In to create a fused battery connection. A Lynx Distributor serves as a fused busbar for DC loads. Multiple Lynx Class-T Power In modules can be connected, creating a longer busbar with more battery connections.
System example – Lynx Class-T Power In, Lynx Smart BMS, and a Lynx Distributor
This system contains the following components:
- Lynx Class-T Power In with two fused paralleled lithium batteries and identical cable lengths for each battery
- Lynx Smart BMS with built-in contactor and battery monitor
- Lynx Distributor with fused connections for chargers, inverter/charger(s) and loads
- A Cerbo GX (or other GX device)
System sizing
Current rating Lynx modules
The Lynx Distributor, Lynx Shunt VE. Can, Lynx Class-T Power In, and the Lynx Power In are rated for a nominal current of 1000A for 12, 24, or 48 System voltages. See the table below for an idea of how much power the Lynx modules are rated at different voltages. The power rating will indicate how big the connected inverter/charger system can be. Remember that inverter invertersr/chargers are used, the batteries will power both the AC and DC systems. Also, be aware that a Lynx Smart BMS or a Lynx Ion (now discontinued) can have a lower current rating.
| 12V | 24V | 48V | |
| 1000A | 12kW | 24kW | 48kW |
Fusing
The Lynx Class-T Power In has spaces for two Class-T fuses, available in 225A, 250A, 300A, 35,0, A, and 400A, and must be purchased separately. Victron does not stock them. The maximum current that will flow in one Class-T Power In is therefore 800A (2x400A). If more fuses are required, a second Class-T Power In (or a Lynx Distributor) can be installed. The total current of 1000 A must not be exceeded.
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 multiple Lynx modules are used. The orientation of the Class-T fuses is important because their connection flanges are not always straight, regardless of the manufacturer. If the connection flanges are not lying flat on the busbar, turn the fuse 180° along its longitudinal axis.
Fasten the fuses with the 3/8″ nuts marked black. Do not confuse these with the M10 nuts of the DC and busbar connections, otherwise the threads of the bolts may be damaged. Note that devices with a serial number starting with HQXXXX have M10 screws and nuts for the fuse connections. They are not marked black. There is no harm in confusing them with the other M10 screws and nuts.
Cabling
The current rating of cables used to connect the Lynx Class-T PowerIntoo batteries is 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 our book, Wiring Unlimited.
Installation
Mechanical connections
Lynx module connection features
The Lynx module can be opened up by unscrewing the 2 cover screws. The contacts on the left side are covered by a removable rubber sleeve. Red is the positive and black is the negative busbar.
Mounting and interconnecting Lynx modules
This paragraph explains how to attach several Lynx modules 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 Enclosure Dimensions 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 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 be the battery and the right side be the DC system side?
- Connect all Lynx modules using the M10 holes and bolts on the left and right. Take care that the modules are
- Correctly slotted into the rubber joiner recesses.
- Place the washer, spring washer, and nut on the bolts and tighten the bolts using a torque of: 33Nm
- 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 this 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 Class-T Power In need to have been fitted with M10 cable lugs. Cable lugs up to 120mm² or 3/8″-4/0 AWG can be used.
- Pay attention to the correct placement of the cable lug, washer, spring wash,, r, and nut on each bolt when attaching the cable to the bolt.
- Tighten the nuts using a torque of: 33Nm
Ground and Negative connections
Connect the ground wire
This only applies if the system requires a ground connection. There should only be one ground connection per system. The ground connection should be made after the Lynx Smart BMS, Lynx Shunt VE. Can or battery monitor shunt. For more information on system grounding, see the Wiring Unlimited book.
Connect the negative wires.
Remove the cable separator post if the wire diameter exceeds 10mm.
The cable separator posts are indicated in allowlow To reach the negative connections, swing the black cable separators upwards. The black cable separators can be temporarily removed by pulling them away from the Lynx Class-T Power In at a slight sideways angle in case better access is needed.
Positive connections
Before making any positive connections, ensure the positive wires are not powered. Disconnect all positive cables from the battery before connecting them to the Lynx module.is This to prevent accidental short circuits. Connect all positive wires. Power the Lynx system by connecting the positive battery pole(s).
Lynx Class-T Power In commissioning
Commissioning sequence:
- Check the polarity of all DC cables.
- Check the cross-sectional area of all DC cables.
