The cheapest and easiest thing would be to buy a 4000 watt generator..
You've made it clear you don't want to run a generator. You'll want at least 120-200 amp hours in batteries. Pulling 30a, on one battery from 100% to 40% will kill that battery real quick. Having two will spread the load and extend the lifetime of the batteries. Wire a 10 amp battery charger that you plug an extension cord into every night.
Have a 4000 watt inverter, pure sine not modified, otherwise you will use 120-150 amps in battery power, just to get 60 amps into the scooters (massive efficiency loss). Have that hooked up to your two deep cycle batteries. Run a power strip and plug in all your scooter chargers. Then when your home plug in the shore power to recharge your batteries.
OR BUY A GENERATOR

I use a marine 2-bank 20a charger like this.
I like having it charge both banks of batteries when I've got the van parked for longer periods. As you can see, there are quite a few configurations depending on how many banks you want to charge and how many amps.
You can get inverter/charger combos but if you have an inverter that works for you I recommend just keeping them separate. Things can get much more complicated as soon as you combine them.
