What do I look for to determine the efficiency factor to know how many watts I can get out of a generator given a specific known HP sized engine?(adsbygoogle = window.adsbygoogle || []).push({});

Example:

12.6 HP gives 9395 Watts from the standard HP to Watts conversion... however on a Markon generator, the spec sheet says that a 12.6 HP engine will provide 7500 Watts.

I am sure that number is composed of data from days of testing, calculations, safety factors, etc. I wanted to see what I could calculate for a 9.9 HP engine but wasn't sure where to start. Is there an industry standard / assumed 80% efficiency factor?

Any thoughts?
