Adding Solar to a Motorhome

I've been doing some reading here and this is what I have gathered regarding adding solar to a motorhome. First, what I currently have. I have a motorhome with a generator, shore power and an alternator, all of which charge the battery to my knowledge. The genny and the shore power are switched through an automatic transfer switch and presumably power the Magnum 2000 inverter charger. Since the inverter charger senses battery voltage it should not overcharge the battery if I add solar. It also has a temperature sensor for added protection. The next thing to be concerned about is the alternator charger when underway. Since the battery charging is regulated when the engine is running and even when the generator is running at the same time if I want to run the house air conditioning, there should not be any issue here if I add solar. This brings me to the issue of adding solar and what I need to be careful of. I can likely handle getting the solar to the batteries without much issue, there's plenty of schematics on the Internet on how to do that. My question is will anything in the solar system be adversely affected by the other charging source as they will all be charging the batteries simultaneously at some time or another. I realize that only the genny or the shore power will be charging at one time but there are absolutely times when the alternator, genny and solar will be charging at the same time. Any help will be appreciated. BTW I have and will keep for the time being 2 12V AGM batteries.
