I don't know what kW i need or whether I should just try to run essentials or everything. I would guess 5 or 6kw. I take it all new generators have an AVR. It's a lot of money only for emergencies but when the storms hit like now, it saves a lot of hassle and problems.The best thing about inverter gennies is that they can run at low rpm for low loads & high rpm for bigger loads so save fuel if your running with variable loads.
Whats sort of min / max loads are you looking at powering?
In the 6kva range I like the pramac 6000s the s is important as its the silenced case that makes a huge difference.
Cases can look the same but not all are sound proofed.
They are good for about 2-3000 hours if you service them well. With another 1000 with a few extra parts.
You will go through starters if you buy the cheap clone ones.
Big thread in here about the ones I have had & fixing them especially the flying diodes.
The frequency off load must have increasedI have an old Stephill 4.8Kw diesel generator which I used in the power cut we've just had. Noticed the fridge was reluctant to start, so checked voltage to find it was 210v so increased governor speed till it was giving 225 -235v which seemed to help. Interestingly, increasing the speed the voltage went up, but the frequency remained at 50c/sec.
I had a diesel generator, same thing, was told the speed has a direct impact on frequency, took the speed up a bit and no change to frequency,I have an old Stephill 4.8Kw diesel generator which I used in the power cut we've just had.

If the generator has an inverter, it would keep the output supply frequency constant.I had a diesel generator, same thing, was told the speed has a direct impact on frequency, took the speed up a bit and no change to frequency,
No inverter on this 1980s model, sorry I should have added that earlier.If the generator has an inverter, it would keep the output supply frequency constant.
