What were the symptoms. What was it doing or not doing.
During the install, a couple circuits were moved into a new breaker box that the inverter should "feed".
When shore power is turned off and the generator is not turned on, the devices attached to the circuits in the new box work properly.
HOWEVER, if the shore power is turned off and the generator is turned on (to power air, microwave, etc.), nothing in the new circuit box will run. Simple, not properly installed with a transfer switch........Nothing to do with the inverter or the generator. If it were properly installed, you would be a happy camper, with the existing components.

Since with most IC's you cannot charge and invert at the same time, it would appear the new circuits are only powered from the inverter. This is why I installed mine "whole house" so these issues do not appear. The only "incompatibility" is the way it's installed.
FYI - my Prosine IC was pretty picky about 'shore' power including generators and wouldn't pass AC it didn't like.

A MODIFIED SINE WAVE GENERATOR........................................
I'm sitting here thinking of all the fun I could have with THIS ONE
How do you wind a generator to get modified sine wave?
Silly Rabbit! Use square wire!
Good luck to you. I'll keep all the info you provided if I ever run across a "NATURE POWER" inverter. AKA Harmonious Battery Honorable Model # Guixdong, Freedom Marching Song Blvd. Member of Loyal Party Member Tractor Plant 431

Back to the question . . .
Is anyone on this forum running the Onan Marquis Gold 5400 generator with a pure sine wave inverter?
Thank you . . .

Faulty, miswired or nonexistent transfer switch between the main panel and sub panel.
Inverter is irrelevant.
Or maybe CW expected you to run these sub panel items on inverter full time (transfer switch not used)
Apparently it has an internal transfer switch.
I assume it is hard wired. Is there a 120v input and output power cable attached?
What does the display say?
Any error codes?

IIRC Wayne's Microlite does not provide clean power to his PD converter. That gen does not provide pure sine waves. The PD does not function well in that environment.
The Marquis Gold manual states it has digital voltage regulation. Sounds that it may not be pure sine wave. I would connect an oscilloscope to the loaded ac to verify waveform.

Sal, "clean power" can be expressed as a definitive number in total harmonic distortion. Few voltage regulators these days do not use PWM (digital) voltage regulation including primary excitation on multi megawatt power generators. It's the STATOR that determines the purity of sinusoidal waveform on an AC generator that is not part of an inverter system. For years I had as souvenirs 150 lb thyristors used as part of the DC megavolt transmission line running through Nevada.
Rejection due to "excessive" THD can be caused in two ways: One is the inverter is junk and rejects waveform more than say 4% distorted. The other is to have a generator (A Generac comes to mind) that loves to outgas electricity with more than 10% THD.
Onan has been around for a long time. I don't believe they would stoop to the point of reducing stator copper to where THD starts infuriating the clientele.
I am definitely not zeroing in on the poster. The inverter manufacturer design and spec department had and has their head somewhere where it should never go. There is a huge difference between an off-grid inverter charger and a UPS. A UPS can get away with claims of needing "perfect" input to charge batteries. An inverter with a charger on the other hand IMPLICATES it is going to be used with a generator.
This point should demonstrate the need for small generator manufacturers to concentrate on inverting output. The old 6.5 NH Onan produced relatively clean waveform.
But the inverter manufacturer is "generating" pure DOUBLESPEAK to the public. Converters built so poorly they cannot handle cheap generator waveform is included.

The Onan has noise spikes that upsets this inverter functionality. Perhaps a few de-spiking capacitors at the inverter can fix the problem. Otherwise, it may be easier to replace the inverter.

There must be a separate transfer switch that switches between shore and Generator. Can you confirm that this is the case?
I don' t believe that this is a compatibility issue as there seems to be no problem with the charge function taking place.
