Is there a manual that spoon feeds you how how to set up the VE bus network? I am not looking to connect to the internet, I just want all my devices to talk to the GX control panel. This shouldn't be as hard as it is, there is a serious lack of information about the nuts and bolts of the process.
Hi @Bdkw1,
It can be confusing the first time through; there are SO MANY possible configurations.
Here are a couple of links that help to explain the situation;

The short story is that the only VE.Bus compatible products are the VE.Bus Inverter/chargers and their accessories (like the digital multi control)
Solar chargers use a different interface called VE.Can or VE.Direct, depending on the model.
It would be nice if everything was simpler, and we are trying to make new products as simple to understand as possible, for now it does take some time to research.
VE.Bus is a closed network. No devices other than Victron inverter/chargers, inverters and the GX family of control systems can connect to this bus. The reason given by Victron (and which makes sense to me) is that the traffic between the various devices is extremely time-critical in that it synchronizes parallel and multi-phase systems. Failure in this synchronization due to unregulated traffic could be nasty. (my words).
The correct way to do what I think what you want is to include a GX device in the system and use that for control and status via ethernet. There are many different protocols which can provide this: modbus, NEMA-2000 (Canbus), MQTT (which is used by Victron's VRM). You can even run NodeRed and SignalK for expanding the functionality of the GX and connected devices.
I have all victron equipment.
When I started it was just the solar an the inverter. The dongle allowed coms with the inverter, solar charger has built in bt. Due to the location of the solar charger, bt wouldn't reach it unless you were standing behind the coach. So I wanted to add the control panel and tank monitor to fix the non op tank gauges. Ran network cable to the multiplus then on to the charger. Terminator plugged into the charger and the GX. All I can see is the multiplus, no solar or tanks. Is there something I need to configure on the GX? How would one go about doing this. There is almost zero documentation in the manuals on how to set this up. But there are 5 different vids on how to connect to the internet......
You know, I bought all the equipment from one manufacturer to avoid headaches like this. You would think this would be plug and play......
The fact that nobody has mentioned a network setup guide/tutorial says volumes. Lots of marketing, very little actual info.
And if you read the manuals of your devices you get all information you need to do it correctly.
It depends on what you have. Some of the things you mentioned do not exist. It's plug and play if you have the right equipment. Provide accurate descriptions or pics as others have mentioned.
F.
This is the main issue. Every component hooks up a different way. In my mind, a network is everything hooked together. This requires a separate cable for each component to the control panel. This is very inefficient and time consuming. If I had known this before hand, I would have skipped the price premium and gone with different equipment.
Ve bus 'network' no explanation needed.
If it is labelled ve bus on the port (only found in the inverter) connect it to the VE bus port on the GX. Done. Plug and play. Use a straight cable.
If you are using more than one inverter, then I suggest you get some training or professional help.
You make it difficult to help you when you don't answer the questions, don't read the manuals and then provide pictures which don't fully answer the questions.
The ports are all labelled. Both on the device and in the manuals.
Connect each device once to the same port type on the GX.
Both VE.Bus and VE.Can can be daisy chained. That's why there are two ports on each device.
Use the supplied terminators at each end of the daisy chain.
Don't interconnect VE.Can and VE.Bus.
You probably don't need VE.Bus, but we're guessing as we don't know what's installed.
Don't create a smart network as you're going to use cables.
Use good quality cables.
There are good reasons for the different connection methods. Pointless to try and explain it here. I'll just say that Victron is used in many different ways outside of what you appear to need to do.
