Have you figured your amp hour requirement? That would be the first step in your planning.

that, you need your total watt hour consumption, then divide by your efficiency ratings *inverter, charger, etc*. If everything can be charged by 12vdc then that's much more efficient and allows for a more simple setup since you don't need an inverter.
The biggest issue for you is going to be battery banks since you need to store all of the power whether it's solar or from the generator. You'll be better off just having a big battery bank that auto-charges off of the generator when it is running *provided you can leave it plugged in when you aren't there.

1800 Watt Portable Power Station and Simultaneous Battery Charger - DCB1800B | DEWALT
More than enough power from the inverter to charge everything at once, and with the big batteries gives you about 300w of charging watts. Not a huge amount, but it'll charge some of your stuff. The nice thing is you can fly with it.
You basically want/need the biggest battery bank you can afford. I use Goal Zero because I got a great deal on them, but they are lead so are heavy. Perks of lead are you can daisy chain them to any 12v lead battery bank and they'll charge. Leave it connected to an outlet and it'll put in as much as it can while the generator is running.
Realistically though you need to figure out the total watt hours that you need per day and multiply it by 2. That's the battery bank size that you need so you can charge everything at once without damaging the batteries. Your solar capacity in wh will be the same as the bank size since there are efficiency losses, but I'd get a big battery charger to charge everything from the generator before I dealt with panels
