3000W Chinese Gensets Info.

Say more. Does this mean that you too experience extreme voltage drops when using the 240V to power 120V loads? Not sure what you mean by 'unbalanced', but I think you experienced the same issue that I have in the past in the same configuration. I don't know whether it is the AVR fault or not (apparently not), but the fact is I cannot use the 240V for 120V loads without experiencing extreme drops of voltage.

Please detail your issue to see how it compares to mine.

Yes, you could have the problem. The generator does not know if you are using 240 or 2x120. It only seems able to keep the voltage reasonably equal if the load on each of the 220V hots is reasonably equal. When using the 240V hots to run 120V loads, you need to keep the 120v loads reasonably balanced. You will have no problem. I don't seem to be able to adequately balance 120V loads.

I use 2 generator outlets and 2 cords. One standard 240 4 prong in the Champions 240V plug for a single 240V load and a modified RV cord for full power 120V loads in the Champions 120V RV plug. No, I can't use them at the same time. I cut all loads and flip the switch when changing voltage. I'm sure there are other ways to do it.

This arrangement is not what I envisioned when I bought the generator, but it provides full 240 and 120 power without low voltage. I don't need 240 and 120 at the same time, so, I'll survive. I hear that Harry Potter is going into retirement. Maybe he will drop by and change some of these inconvenient laws of physics to suit me. I did buy all the books and movies for the Grandkids.
