3000W Chinese Gensets Info.

I looked at the circuit diagram again. In my opinion the AVR only monitors one winding under the 120/240V plug. This would explain why loading the other side with a sump pump would cause the Voltage to drop. (no regulation!). Can you triple check your diagram and confirm what you see?

Well, just trying to help here. I have worked with the AVR's on these things, their principle of operation, voltage regulation and such for over six years now. What I wrote in my first post concerning loading is what happens. A detailed explanation of how regulation works has been posted in the past but finding it in all the stuff that has been posted on this thread is a trick in itself. I don't even remember when or what page I did it. If necessary, I will repeat the explanation.

That said, there is absolutely no way a properly operating generator of your type with a sump pump on one leg and a few 100 watt bulbs on the other should show a 30+ volt differential. Did you try swapping legs as I suggested to see if the problem was the same? If it is the same I would suggest looking at your cord/adapter. If not, you need to return the unit or call the customer service number on the genny and discuss the problems with one of their techs to get some direction as to what they want you to do.

Also, this is driving me CRAZY... So essentially I have a 3500 Watt generator, but I have no way or utilizing the full capacity in my household (for emergencies). I cannot find a TT-30P RV cord with the RV plug on one side, and regular 120V household plugs on the other. That I think would solve my issue.

Again, thousands, perhaps even millions of Chinese open frame synchronous generators of a similar type to your model are operating all over the world with the capability to use the full capacity from the 240 plug. CPE is currently the only company that provides an outlet for direct connection to a 120 volt 30 amp TT plug without an adapter. Their approach is the best for RV usage but not something easily plugged into for someone without an RV. Something is wrong with your genny, adapter/power cord or readings - what you are reporting is not normal. From a distance I would strongly suspect a high resistance contact or connection somewhere in the circuit displaying the lower voltage. Maybe the voltage selector switch for example. One thing for sure, with a 30+ volt differential you should easily find it by looking for either smoke or heat.

I doubt that you will find a TT 30 amp cord that will give you more than one standard household plug. The 30 amp TT to a single standard outlet is a common adapter that any RV store should carry. The problem is getting more than one standard plug on the adapter and going beyond the typical 15 amps down-rating. So, you will have to make the break out box for the 30 amp TT outlet. One simple method is to purchase a 30 amp male pigtail such as this one and then pick up two 20 amp duplex outlets, a 4" square utility box, cord clamp and cover from a home store like Lowe's and wire it up yourself. Takes less than 30 minutes. You may find the same 30 amp pigtail at your RV dealership and be able to save shipping.
