Same thing in my case... and if you notice there are more and more inverter generators out on the market for this very reason. Don't have to buy a Honda there are other offerings out there but no matter the case these are noticeably more expensive than their non-inverter counterparts. That said if you buy some cheap piece of crap it's not going to make much of a difference what it is, other than a piece of crap!

Not trying to kick up an argument here either guys, just pointing out you gotta be careful with these things or you may end up with a problem. Stuff now a days is not like it used to be and all these electronically controlled devices get a little fussy.
I did some research and it looks like you are correct. It appears that some low end generators have a high Total Harmonic Distortion (THD) that can harm some electronics. If a generator has over 5% THD, some sensitve electronics can be harmed.
Some furnaces won't run with over 5% THD and like you said it caused a big problem with your brother in-laws furnace.
