Hi @solguy,

I think the best way would be something via the ethernet port of the CerboGX, to another network connected accessory screen, such as a cheap little laptop. Then using the Remote Console over LAN feature. It can be done direct point to point, without a router or other networking equipment. As long as the other device has Link Local Addressing compatibility.

Then it a matter of how do you get the local network/ethernet connection 50M.

There are MANY options for this of course, you could run a gel filled weather proof CAT6 cable in a shallow trench.

You could string it along an overhead catenary.

You could get some directional wifi antenna, or higher power wifi equipment intended for outdoor use (ie Unifi).

Another possible option to consider is Ethernet over Powerline adapters. This may be the easiest and cheapest option, IF you are also already running the powerlines back to the 2nd structure from the power system.

Ideally you can borrow some to see if it works first.

I have had reasonable success with TP-Link AV2000. Though it is possible for them to not connect if there are too many switches or junction connections, so try to keep the power wire as uninterrupted as possible between the two units.

I have not experimented with extending HDMI and USB long distances, though I think I will get more of a chance once the CerboGX is released.

It has not been reliably tested yet, as far as I know. So currently unsupported, but not prevented.

The HDMI cable is hard wired to the screen side. So you would need a joiner, or better yet a dedicated extension cable, which seem rare.


I don’t know much about HDMI, but the USB power supply voltage would not survive that range. So at least that should have an external USB power supply closer to the screen.

Forget HDMI over that distance. Anything over 15m is a gamble even with decent cables.

I currently use USB extender cables 3x20 meter Off an AC POWERED usb HUB to connect a second solar controller in an out building 50+ meters away from my CCGX

The USB hub is at the controller end

Have been using it UNINTREUPTED for 8 Months Without any Issues

Quality of cables is the Key

Thanks for answers, I think that a RJ45 CAT6 is the simplest option . Is this ethernet RJ45 cable connection give the power for the screen or it need aditional power supply ?

At the moment Bluetooth is only for making the WiFi/Ethernet settings.
More BT features will come later.

That's a really long run for HDMI. I've seen ethernet to HDMI repeaters, but I've never gone that far. USB repeaters should also pose a problem. as I've never gone more than 20 ft, but I guess you could stack repeaters. I've never tested it so I'm not sure. As Murray stated, if you have a local network, you can just pull up the remote console. If you mean no internet as no local network, then you might want to try those USB HDMI repeaters, but 50 meters is a long distance.

The Cerbo has a HDMI interface, I’m not sure how practical (and workable) a cabled solution would be. Why not try remote console? You could achieve this on a local network, and view the remote console on a mobile device

The Touch 50 is a nice elegant solution for installation into an RV. It would be nice to have a solution that would allow the Touch 50 to be installed in a clearly visible location and have the Cerbo installed next to the power equipment typically in a remote location. If Victron could put some energy into testing possible solutions I'm sure the community would appreciate it. Especially since there is now a delay on delivery of the Cerbo to the community that could be sharing knowledge.
