I bought two 48v5000 watt Quattros for my RV. It is a 120v system with a dc system as well. I'll have solar and i have a single phase onan 5500 watt generator. What's the advantages and disadvantages of hooking them up in parallel versus split phase.
Really there would be no difference re performance wise
it will all depend on how your RV is setup,
I prefer Parallel personally, (but then I am in a 230 volt 50 hz country), as it simple and you only have one bus that way otherwise you will have to balance the loads so that each phase has close to equal load.
My RV has two 120V legs. If I hooked one up to one leg and one to another then the generator which is single phase and the shore power is a problem. I guess I need to do parallel.
Let's slow down a little. I suspect you are in the US, so am I, and that your RV has a "50A" shore power service connection. If so, what you actually have is a 120/240V 50A Split Phase setup. However, it is 50A at 240V or 12,000 Watts of power available. That equates to 100A at 120V.
Split Phase power is an issue with RV's and how they are wired, especially when it comes to adding Inverter/Chargers.
Please confirm if you have a 120/240V service, and we can get into the weeds some more.

Alan,
Please take what I am about to say in the spirit of my trying to help. I strongly suggest that you contact a US Certified Victron Installer, with RV experience, for help in installing your system. You are dealing with high voltage/current that can cause major injury or death if you don't know exactly what you are doing. Not to mention irreparable damage to some expensive equipment.
Please take my advice,
Pat
Oh I'm not touching this stuff myself. My installers have 40 years experience between the three of them.
