Well as I have mostly Victron stuff in my camper I thought I would like a full display of the system. Then problems appeared........ the cost of the Victron touch screen 50 is..... £199.00 and the cerbo GX controller is..... £200.00. Wife states
"your having a laugh"....... Back to drawing board:
1 x old rasberry pi 4b found in a tool box in garage
1 x rasberry pi 5in screen (bought from amazon)
1 x Victron software (free) for rasberry pi:
raspberrypi install venus image
2 x Victron Energy VE.Direct to USB (bought from amazon)
1 x 2 meter HDMI cable found behind TV not used
1 x 2 meter USB Type A to Mini B (for screen)
1 x ethernet cable (to mini router in camper)
4 hours of my time......
Total cost..... a lot less than £400.00
Flashing raspberry was simple. Fitting in campervan took most of the time as had to connect VE.Direct cables to solar controller and smart shunt.

Above: The raspberry pi is fitted in rear cupboard out of the way. Tight squeeze to get cables across van to raspberry pi, but got there.

Above: The screen is touch so can zoom around the battery, solar etc or as I find I just leave it on this screen. When on EHU (not very often) the "green box" shows power coming in from charger or when driving the same box shows the DC to DC charger pushing 30amps in as well as solar panel "yellow box"

Above: The screen was the hardest thing to fit as did not want it to look out of place or cut into the wood panel. In the end fitted the cables behind panel and stuck the screen on. I/we
(wife thinks it's great now!!!) can now see state of battery etc all the time and this helps lots when using inverter to see whats going out in amps.... Screen can be switch off when not needed.
The best thing I think is remotely seeing state of charge etc... when not near camper. So when parked up I can connect via computer at home to the controller and see it all.
Is it worth it? perhaps not for everyone, but better than using the phone to check battery, check solar, check EHU etc etc etc. All on one screen.
