First, If you don't pull the main breaker then you are trying to power
up simultaneously all items that are "ON" in the house... but you
already knew that :-))
Second, your AC and refrigerator motors may only draw about 20Amps once
running, but for a few millisecondss, they suck a whole lot of current
on start-up. Look at your 12V battery when you crank the starter...
4 KW max only gives you 18Amps max @ 220V.
The longer your connecting leads the higher the resistance and the more
voltage drop you get which increases the current demand which increases
the voltage drop, etc., etc., etc.....
One 100W lamp almost draws 1 Amp @ 110V
You probably need to check on what is the peak current the generator
can provide for a second or two...
But I would definitely pull the main breaker
