Are there certain "specs" to look for when using a generator
on sensitive electronics?
Total Harmonic Distortion (THD) is one spec to look for.

"Total Harmonic Distortion (THD)
Total Harmonic Distortion is a means to measure the quality of
electricity. 6% THD is considered the upper limit for "clean"
electricity. Above 6% THD the electricity may reduce the life
of electrical circuits, cause microprocessors to malfunction
and cause furnace controllers to operate incorrectly. All
NorthStar generators have THD less than 6%. Some generators
produce THD greater than 15%.
Brushless Alternator Design
Brushless alternators require less maintenance and produce
cleaner power that is more suitable for sensitive electronic
equipment. Brush-type generators have brushes that are wear
items, requiring replacement."
