1999 Winnebago Ultimate Freedom Electrical Issues

We just bought a 1999 Winnebago Ultimate Freedom 40JD. It came to us needing what we thought was just new house and chassis batteries. We have replace all batteries with 12v units according to Winnebago specs. 3ea deep cycle for the house and 2ea starting for the chassis. We have run into a few issues (at least I think so) with the Xantrex inverters (2ea.) in the coach.
Her are is a list of the non-working items even though there is power to the outlet receptacles they are plugged into:
1. Front TV
2. Microwave
3. Cook top (spark start)
4. Fridge on AC and LP (controls light up but display no AC or no LP)
Another issue of concern is when the generator is running one inverter (labeled air conditioner) shows AC in and starts to charge the batteries. The second inverter (labeled house) does not show AC in and does not show it is charging the batteries and there is no power to any of the outlet receptacles that I believe to be controlled by this inverter.
Also when running the generator there is another monitor that shows that the generator is running and there is 50 amp service. I believe (according to the instruction book) that the 50 amp and gen set lights should not be on together.
I suppose we could have been misled and the listed appliances may just be broken but I am a bit confused on the inverter issues.
Can anyone explain?
1. How these inverters are supposed to work?
2. Are both inverters supposed to be hooked up to the same 3 batteries and not be treated as separate systems?
3. What is the best way to test the inverters charging and AC in sensing function? I hate to buy a new unit if this one is working as it should.
4. Could any of these issues be caused by the Automatic Transfer Switch?
5. Are the inverter control panels supposed to stay on all of the time? Does this drain the batteries down faster than the solar panels can recharge?
Please help!

I turn them off when I don't use. They are sucking the juice out of the battery. Keep it simple when you are checking things out. No 12 volts to the ref. means it will not light. Someone should jump in who has your model. Before you try to light the refrigerator light the cook top so you can get the air out of the system. Ensure that you have 12 volts to the ref. Can be check on the outside panel. Welcome to the forum. After you get everything reset and check post back.

Usually on the inverter itself there is a reset or resettable fuse.
Have you tried that?
Are the outlets you mention GFI and need to be reset?
