Petrol generator has surprisingly low KVA?

Don't know if I am reading this right but the website you linked to says 3kVA peak and 2.7kVA continuous?
The 2.7kVA rating is for continuous power while the 3kVA rating is momentary for loads with large starting current I imagine. Real power in watts does not seem to be mentioned anywhere.

Since the continuous output power rating is 2.7kVA it cannot power a 3kVA load continuously.

This is my thinking also. Additionally while you mention:

While you mention sixty 50 watt loads which is 3,000 watts assuming full load on each unit you are pushing your luck and your generator trying to run maximum. Even a 3,000 watt continuous power would not really be sufficient as there is no head room. I would be looking for a generator capable of 4,000 watts continuous power. To answer your question yes or no I would say no. The linked generator would not get you where you want to be.

Key point to remember:

With a generator (or UPS for that matter), it's not real power (watts) that matter – it's KVA. You pay a penalty for a crappy power factor.

Thanks, yes, sixty non PFC'd loads as described would draw about 6KVA.
