And there in lies the problem. What does the OP have? Unfortunately they haven't returned to answer that question.
Based on Post #1, they have a 2022 High Country with the 400 watt solar package. AFAIK, that comes with the standard, limited function, inverter feeding 7 circuits, and the standard converter. The inverter doesn't have load sharing.

There is a an interesting claim in the product description saying "2000-watt inverter w/ built-in transfer switch (up to 7 inverted outlet),
second inverted loop for A/C". Later on you find a related(?) statement that "
** Second inverter and compatible air conditioner required. See dealer for details.". Not being current on all the solar options offered by Keystone, I am unsure about the AC reference. But knowing Keystone, it means that ain't happening with a stock install.
Having spent a lot of time with you, Drifty1, Ron and Ron, I am aware of the load sharing inverters, I saw first hand Drifty1's experience in Lincoln, NE when the 30 amp power went out with two ACs running. I didn't introduce load sharing into my original response as I am pretty sure it was not an option the OP has currently and definitely makes the discussion more complex.
