I was told by the company I bought my generator from that when you start a motor the power required is, initially, at least treble the wattage. So when you start the third motor the genie needs to be able to supply 5kva, minimum. Sure there's someone out there that will correct this but only passing on what I was told. 

This is true to a fashion.    Motors do draw more current to start.  But not always 3x the ratted wattage.    

A 4kva generator will have a peak cut out of about 5kva  (2-3 seconds).   

I can run a 1200w angle grinder on my 1kva inverter generator.   Yes it struggles, but it does it.     

4kva (assuming a power factor of 0.8) should be more than sufficient to run a 3kw vac.

Also to add.   A company that sells generators told you to spend more and buy a bigger generator??   Yeah, because they assume nobody but them understands electricity and current draw. 

thanks for replies looking to get 5kva generator

I'm looking at buying an inverter for using my gutter vac, but unsure what spec i need. The gutter vac is the skyvac Atom 1600 watt, and  i'd appreciate if someone could clarify what i actually need to buy to run the vac without any hiccups, i.e. cutting out, overloading etc;

Will do. I may try starting a new post, as this was an old one i added to.

Spinaclean are the maker/ supplier of the Sky Vac Atom.Give them a call at least then you can act on their advice and ensure that any warranty remains in place.

Ive been dealimg with Mark Nice at spinaclean in last cpl of days and hes been really helpful.

Any ideas if this will power a skyvac Atom?

Looks like 650w output.. Would not of thought it would be up to the job.

Ideally whatever the vac is i.e. watts you want three times the watts from the gen to start up the vac.

Under powered gens will run the vac but, you will find there vac has reduced power so when you come across a plant it wont budge it.

Thw Atom is 1600w so you think ill need a 5000w gennie?

Best person to check with is Spinaclean. 

We use one of these for our Grippavac outdoor gutter vacs.
