Wyatt,

Not sure I understand the issue.

With a manual transfer switch set to "generator", when the automatic generator start system starts the generator, ALL circuits powered by the main breaker box (which is what is fed by the transfer switch) are powered.  So, whether converter or inverter/charger, they are powered.

BTW, no different than with an ATS.  Same circuits are powered by generator.

I removed the inverter power panel and rewired all loads into the main panel.
I reorganized all breakers in the main panel and colour coded them "Red" for the red hot, and "Black" for the black hot.
I installed two manual 65 amp selector switches in the empty space at the top of the power panel.
One manual selector switch selects Shore, Genset, or Inverter to power the "Red" breakers.
The other manual selector switch selects Shore or Genset to power the "Black" breakers.
I separated the neutral bus bar into two neutral bus bars, one for "Red" and one for "Black"

This results in me being able to load balance between red hot and black hot and have the red breakers on Inverter while the black breakers are on the genset or shore.

I ran a second neutral wire from the power panel to the utility bay where I installed two 40 amp, twist lock receptacles, one for "Red" and one for "Black".

Now I can connect two 30 amp power cords to shore power, one for "Red" and one for "Black". even when the shore power receptacles are "ground fault" protected.

I seldom use the 50 amp (really 100 amp) power cord because almost no campgrounds on Vancouver Island have 50 amp receptacles.
I will attempt to post pictures!

Brett, I was responding to Reply #24, third paragraph, which discussed using a manual selector switch with genset autostart.
Thanks for your input.

My ATS has failed. Does anyone know where to order an ATS 100 that will fit in the space in a 2000 U320. I have researched the forum but do not see a listing for a replacement.  Thanks for your help. Ken

Ken,
If you are a DIY kind of person you can rebuild the ATS 100.

If it is just the contacts that are burnt they are replaceable. We are on the road and don't have the part number for them but I think the number has been posted here on the forum somewhere.

If the coil/relay is bad it is also a replaceable item. There should be a sticker on the relay that will give you a part number that you can cross reference.

How has it failed?  Which ATS?  ATS 100 has not been sold for many years.  Other ATS are available, some have the three 50-amp cables terminated in a different position.  As others have said ATS 100 points are available, although not real cheap, sold as each.  Also another alternative is your coach probably has two identical ATS 100 transfer switches.  The inverter ATS only uses 2 of the 3 relay points, so there is another option for a repair.
