The lynx Sprinter Van Solar Energy Distributor system is a modular DC bus bar system used to connect batteries, DC equipment and provide fusing and battery monitoring. There are locations for four DC fuses and it will monitor the status of each fuse as well as indicate its condition with a LED on the front.
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.
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.
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.
Q: There is a small 4-pin cable shipped with the Sprinter Van Solar 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 Sprinter Van Solar 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 )
