Features

A modular DC bus bar, with locations for four DC fuses. It will monitor the status of each fuse, and indicate its condition with a LED on the front.

Lynx Distributor

Contains a positive and negative bus-bar and provides a connection for 4 individual DC equipment circuits, loads or DC groups. It has a space for individual DC fuses per DC group.

There is an optional feature of an LED for each fuse to indicate if fuse is blown.

If you wish to use the fuse indication LEDs on the Lynx Distributor, it also requires a connection to a Lynx Shunt. The Lynx Shunt contains the necessary wide input (8 to 70VDC) power supply to output the required 5V (4,5V-5,5V) power requirement of the Lynx Distributor circuit board.

RJ11 fly leads are used to connect the Lynx Shunt to the Distributor. This RJ11 cable is supplied with the Distributor in the box. There are two ports on the Lynx Shunt, and it is possible to use either.

When all is OK, only the central LED is green; when a fuse has blown (or is missing) the central and blow fuse circuit LEDs turn red. If you are not using all connection points in your DC distribution, it may be necessary to fit dummy fuses to extinguish the red LEDs.

A future upgrade is planned to also send info back to the GX device over the VE-can, but is not yet implemented.

Fuses

Uses MEGA fuses. Please note that some MEGA fuses are only rated to 36Volt (suitable for 24V systems), You must use 58/64V rated fuses for 48V systems.

Installation

Connectors and dip-switches:

  • The R11 connector is to power the Lynx-distributor from the Lynx-shunt
  • The DIP switch on the Lynx-distributor are for specific manual settings, to do with our 24V batteries. Please don’t touch.
  • The 6-pin header block on the Lynx Distributor is for reading out the fuses, but this feature is not supported.

FAQ

Q – There is a small 4-pin cable shipped with the Distributor – I can only assume that the cable interconnects between the Shunt and Distributor?

A – Yes, but this has only to power the LEDs on the distributor, there is no other function for this at the moment.

Q – The Distributor has a DIP switch. What are the settings?

A – That’s for manual settings, please don’t touch as the system will auto configure (up to 32 battery’s )

Q – The Distributor has a 6-pin header block. What is it for?

A – In the future, the read out of fuses, but this is not supported yet.

Why Fuse the Bus?

Batteries are special. They are both a source and destination of energy.

Power can flow from them to a load (or a fault). It can also flow to them from a charge source (eg other batteries or solar).

It is important that in cases where batteries are combined, and there is the opportunity for current to flow from one connection to another in fault, that there is sufficient and robust circuit protection.

For example, the BYD Lithium IP55 cabinets.

In this case the 4 module battery cabinets are each protected by individual 85A circuit breakers and also collectively protected by a 125A circuit breaker at the cabinet end.

These cabinets are then connected through the Lynx Distributor, and those main battery take off wires are connected at the Bus end by another 125A MEGA fuse.

Both the 125A circuit breaker and the 125A fuse are as close as possible to their respective sources of current. The battery cells, where the internal wire is protected inside the cabinet. And the shared bus bar (where current can flow from other batteries or a charge source).

This means that if there is a short circuit fault somewhere along the battery cabinet take off cable, there is sufficient protection.

Without the 125A bus bar MEGA fuse. There is the possibility of the battery take off cables fault that the 125A cabinet circuit breaker trips, but that the fault is continued by the supply of the other batteries (up to their combined 375A) and this exceeds the current rating of the cable to the fault and starts a fire.

This is an unlikely scenario, but consequences of a fire in an energy storage situation are so serious that it is a recommended level of protection.
