As per your lithium battery charging, as with only being 100a mppt solar chargers at the top end, it would seem splitting the bank to charge and a disconnect to tie them together if the need arose to use all 600ah. Disconnect or split the bank in two either have one charger to charge one half at a time or two separate chargers.
This is my opinion just shooting from the hip, I would need to do some research but, where there’s a will there’s a way.
Every system in every coach needs extensive research. You can’t just run out to your electric meter and take the kWh per month and throw in a system. No matter what it is. That being said...if someone wants a 230ah bank and only 200w of solar, by all means have at it. If someone wants to charge at a 5%-10% rate then by all means have at it. Will these work? Probably, will they work well? Guess it doesn’t matter...
Mine does, so I’m happy.
No one ever said you can’t charge slower but it’s fruitless if you can’t charge your bank fully in a day....IMHO!
Maybe I should do this...
DISCLAIMER: this is only an opinion. No real research has been done by me on lithium battery charging in an RV. Boondocking situation with solar, inverter or converter. I will refrain from commenting further on lithium batteries and chargers.

Not sure what you were driving at, but MPPT solar charge controllers can be hooked up in parallel, but Victron does have a 150A so I would only need one in any case.
