Trace inverter settings needed

I have changed inverter settings and would like to reset properly. I have the two original 4000 series. With engine running the interior lights are flashing. When I turned engine off and ran generator, I think I smelled electrical overheat in generator area. Worried that because house batteries are very low I am over taxing something perhaps due to incorrect trace settings. In coach now trying to move it from storage to my house.

The factory settings are good with the only tweaks needed being battery type and charge current. How many batteries do you have and are they 4D or 8D. I assume they are Lifelines.

If the interior lights are DC and are flickering, it could be the dimmers need to be turned up.
