I believe, Victron specs wire and fuse size in the manual.
Apart from wire size you need to pay attention to insulation temperature rating.
Is my set up safe?

The main thing about a recirculating shower (imo) is that it is used to cleanse the sweat off, rather than a 'full' shower, thus your use of soaps/gells needs to be minimal or else you are rinsing yourself in soapy water. It really depends on your required needs and to a larger extent, who the occupants of the RV are.

Why not update your drawing with all the wire sizes.
You have speced over current protection so why not wire.
If its a mobile application you want fine stranded wire.
If its stationary you don't have to use fine stranded wire.
I suggest pure copper with insulation rated to 105 Celcius.
In North America its measured in American wire guage up to 4/0 and kcmil beyond.
The rest of the world uses square milli-meters.

Assuming this is the right model: "MultiPlus 12 | 3000 | 120 - 16 | 230/240"

You should have the disconnect between the panels and the solar charge controller.
You don't need one on the system side of the solar charge controller.
You don't need them in front of the inverters.
I assume you can turn them off
you should put a disconnect between the positive busbar and the battery.
Oh and a 300 mrbf fuse on each battery postive terminal.

Updated my design Thanks to all for input.

He has one (I think), look near the bottom right corner of the SCC, I believe taht is a double pole breaker.

Actually @Solarfun4jim why not go 24 volts?
Make those cells into an 8s battery.
Half the amperage of the system.
Half the size of the wires.
The switching gear will be able to handle the load with relative ease.
Get per cell balancing.

I concur, 24v makes a lot more sense, especially considering that you don't seem to have any DC loads (one of the main reasons people often stick to 12v).
I see many upsides and no downsides in this situation
Your charge controller will be a lot cheaper too.

Guys you are right again. My original thinking was utilising some 12v equipment, but that has been negated now. My BMS has 8 attachment wires anyways.... so yes, it does make more sense....will recost the SCC and inv/charger now. Fortunately i have still to purchase these. Cells and BMS i have now got. Solar panels on the way....everything else just to be sourced now.
Only addition i might add later is a sterling b2b but that is fine also with a 12v - 24v unit....so no probems.

Inverter/Charger will be the same price, but you can now either get an SCC half the size (and hopefully half the cost) or a PV array twice the size.

I don't think you need the disconnect anymore since you can turn the inverter/charger off and you have panel side disconnect to turn off the solar charge controller.
You could even go with a 2 position mrbf terminal fuse and get rid of the positive busbar if you wanted.

Guys....this has been fantastic. I will be checking out everything that has been added, so thanks.
Early hours of the morning here, so time for me to head off now.
