I think I need a bit more information on what you mean. For example, you probably should have some kind of energy management system that will control what systems get powered down if you exceed your shore power capability. That would be most common if you were on 30 amp shore power. Intellitec Smart EMS is a fairly common model.
I have a Magnum Energy control panel. Generally speaking it controls use of the inverter and charging systems. It also is the tie in point for optional automatic generator start (AGS) and battery monitor systems. In effect it is the brains of your charging system along with your converter/inverter system.
You probably could (if not should) also have some kind of whole house power surge protection that can play a part in providing information on what kind of power you are on. Most bay mounted units will delay allowing shore power from reaching your coach until it has had time to analyze it and make sure it is stable and safe. Some models will even have a remote read out to tell you all about your power including voltage, amps in use, cycles (hertz) and fault codes. This would be in addition to any other power monitoring systems.
BTW...as long as you have turned on the charger and/or inverter, they stay on until you change those settings. The display panel has a power saving setting that turns the display off after a period of time but nothing else. Touching any button ONCE activates the display without changing any settings. You should read the owners manual very carefully to make sure it is properly set up for types of batteries you have and lots of adjustments to meet your coach battery/generator configuartion.
Hope that helps you get started.
