Now you have. This is the wave form of a cheap 5.5kw Briggs generator
with about 98% load on it.

This shoots the hell out of the theory that you need to derate the
generator because you are running on propane ... at least the 5.5
Briggs anyway. Maybe they just oversized the engine tho.

That is 5402 watts. Over 98% of rating.
Â* Is that the "Storm Responder" model B&S generator ? Did you get a
snapshot of the waveform at a lower load ? I dunno what you call cheap ,
mine cost me around 900 bucks several years ago .
I am not sure this has a name like that but I got it for $300 second
hand, still in the box. A guy bought it after Charley and 10 years
later he sold it to me. It sat in my garage for 3 before it ever ran.
I had the parts but I put the propane kit on it after Irma, in the
blackout. It only took about a half hour tho and I was back up again.
I didn't look at it unloaded with the scope but I was watching voltage
during the outage and it was steady at 115/230.

I also added these loops after the cleanup was over from Irma so I can
check each leg of the 230 to be sure I am balancing the load. I had to
open up the panel to do it during the blackout.

Â* Mine's routed thru the shop sub panel to the main and we only run
minimal loads so I don't worry about balance . Lights , fridge , TV and
internet/computer stuff is all we usually run when on emergency power .
