CPE is giving THD numbers higher than what I have measured on my unit. Interesting - it usually works the other way.
I might be willing to give up the 240VAC if there was good gain in AC signal quality.
I was able to find a thread where you tested a 4008 and found the waveform to be quite good. Have you tested other models? I looked and did not see anything other than the 4008 waveform and some examples of other mfg (I think) waveforms.
I'm looking at the 46514. If that machine is known to be noisy (or has any other issues) I'll go for another - even just 120V if I have to.
At this point, I don't need elec start so I don't want to pay up for that unless I'm getting something else and the elec start is just an "extra".
Given that the only units that have the load delay/shedding are the remote start ones, and that feature only applies when using the remote, I'm willing to forgo it and come up with another means of ensuring the generator is not started or shut off while load is applied.
I was hoping to gleen something from the parts listings between to 4008 and the 46514. It looks like an older 4008 and the 46514 are close, but I don't know what that -2.5 suffix is on the stator assy. I'm guessing that the new 4008 parts numbers are related to the load delay/shedding since most of the other 3500/4000KW units seem to still have the "old" part numbers.

I added this since you referenced it and thought it would be interesting to see if any parts crossed over.

Why do you need 240 VAC? About the only item you can use it for in the USA is a small (1/2HP) shallow well pump. If that is your goal and the noise level is not of greater issue the new 41533 is a a 46538 on steroids. It has a 50 amp RV plug and all the safety features. It makes a great home back up unit when coupled with a transfer switch.
A home backup with transfer switch is the goal. I could probably do what I need with 120V but there wold be less work more flexibility with 220.
41533 is too big for me. I can run my essentials: sump(700W), gas heat blower(875W) and refrigerator(65W) on the 3.5K unit.
