Adding EU and NA shore power inlets for charging RV batteries?

[Crocdundee]

I am in the process of installing an upgraded Victron electrical system in our imported RV and I saw a pretty interesting idea of adding two shore power inlets to cover 120VAC (NA) and 230VAC (EU) - see video at bottom of post. I don't think Victron makes a 120VAC shore power inlet as he has shown, so I am guessing he has two EU shore power cables with different ends for each style of pedestal.

The RV I purchased came with a Blue Smart Charger 24-16(3) 230V that I will have extra from the build project as I am installing a MultiPlus-II 24/5000/120-95 120V that will cover our inverting and charging needs in the USA. I am installing a new 120VAC shore power inlet and was wondering if anyone has any experience or knowledge on wiring in a second shore power inlet for international travel (which we hope to do). I believe I will have some extra 10/3 cabling and was just thinking of running another leg to a 230VAC outlet nearby the batteries that I can plug in the battery charger if we ever happen to travel overseas. There is also the option of installing a Victron 32A Autotransformer before the inverter and selling the smart charger, but you still end up needing to run another shore power inlet to the autotransformer but you do keep the MP-II as the charger alongside all the existing breakers inline to the Multiplus.

Questions

1. Is it as simple as that (albeit with a surge protector at the RV pedestal) or is there something that I may be missing?
2. Would it be ideal to add a 230VAC breaker at the one outlet supplying the battery charger?
3. As long as the batteries are charging via 230VAC shore power and via solar MPPTs, I assume the Multiplus will still invert as normal just without charging?
4. Would the 230VAC shore power wiring cause any issues with any nearby 120VAC wiring?
5. Anyone have any highly recommended shore power inlets?

Just thinking of any useful wiring I can do while I am in the process of installing my own Victron 120VAC setup. Would be much easier to do anything now than when everything is back in place.

Clear skies!

Are you planning to reprogram the Multiplus for the two different voltages?

No I was planning on keeping the MP-II as factory set to 120vac. My plan is to run the 30amp 120vac shore power inlet to the MP-II and then the other 230vac shore power inlet to the blue 230v smart charger (via a single 230VAC outlet) that would then tie into the Lynx Distributor. The MP-II will not be able to charge the batteries if it doesn't have AC-IN correct?

Yes its as simple as just buying a 230v charger and wiring up to the batteries. Let the inverter stay on invert mode and have the 230V charger provide power to the batteries.

230V to 24V then 24V to 120V. You lose a bit of efficiency but who cares since you're on shore. You could even get a couple of chargers and as long as you aren't overloading the batteries charge rate you'll be fine. Once batteries are topped off it should just power the inverters

Thanks for the reply and knowledge Justin, going to go ahead and add this step to the install just for the heck of it since I already have everything. Only thing needed was the Marinco EU Inlet, which I found a great deal on Ebay for $30 ($24+ship), typ. they are $80+. There's a few more left if anyone needs one, quality TBD as haven't received mine in the mail yet. Link here: https://www.ebay.com/itm/395413074054
