I have a new 12v system I’m installing consisting of 6x100Ah Battle born batteries, a Multiplus 3000 Inverter/Charger, Lynx Distribution system with 1000Amp shunt can, and a Cerbo GX. I have some question on the wiring below.
The batteries will be connected into two Lynx distribution panels connected together. They will be connected into ports 2-7. I will connect the positive on port 1 (with 400A fuse) and negative port 8 to carry the load to a 400A single pole on/off switch and the Shunt can left side leads.
That run of 4|0 AWG (107 mm2) will be about 4-5ft for each cable from the Lynx to the shunt. Each battery will connect in with 2|0 AWG (67.4 mm2) 24” or so (all equal length).
On the right side of the shunt can will be two more lynx distributors to feed the system. One of these runs will go to the multiplus.
I plan to connect the Multiplus to the Cerbo GX over the VE.Bus port (RJ45). I will connect the shunt to the VE.Can port using RJ45 and one terminator on the other port of each device.
A few questions on the other sensors/wires:
Is it possible for Cerbo GX to be powered via VE.Direct (Power over Ethernet) rather than use the included fused connection?
I have the temp sense wire that came with the inverter, and I see the instructions about creating a v-sense 18AWG cable in the forum, but I am confused about where to connect these in and to which device(s).
The shunt can will determine the voltage on the input from the battery bank at the left side terminals but there is more cable to account for (5 feet of 4|0 AWG plus the runs to the batteries). I could wire the v-sense on the port 1 and port 8 +/- sides of the battery bank lynx setup which I think would be the place to measure.
What about the temp sense, and should the temp sense be connected to the shunt can and it will inform the rest of the devices about the data? Otherwise I would be looking at running t-sense to the shunt and the multiples separate.
Regarding the RJ10 cables to connect the shunt to the lynx distributors, should these be connected within each location in my setup ie connect the shunt and load side distributors together, and then connect the two lynx that are together in the battery bank to each other, but not all together?
Please advise on the best way to set this up. Thank you kindly for any information provided.
