Question is how long itd take to charge 420ah using a 700w generator.
It'll take several hours to charge a 420Ah bank. A medium sized battery charger will put in 40 amps. The thing is you can only charge at that high for "bulk charge", then the amps will decrease to finish off the charge, then they will decrease further to float charge. Probably around 5 or 6 hours to charge from 50% to 100%.
A 700w generator should be up to the task, though.
Solar is really the way to go for something this size. You can get 2x 300 watt panels for a reasonable price. They'll put in that 40 amps with no problem and do it silently.
