I am curious as to how the 12 volt system works when plugged into shore power.
Does the inverter keep the batteries charged, and directly power the 12 volt stuff on the motorhome, or do the batteries provide the power and the shore power keeps the batteries charged?
Maybe this will be a clearer question than the one above: Is it necessary to have the house batteries hooked up to provide 12V power to the motorhome?
Clear as mud? :)
draboo,
It would be nice if we knew the make/model/year/engine etc. of your coach. We could give more accurate answers to your question. But, as has been stated, if you have a gas coach, most of those came and come with, a "Converter/charger". That is, the converter takes incoming A/C voltage and, changes it to 12VDC for coach component operation if and when, plugged into shore power. It will also charge the house batteries. Some, depending on how they're wired etc., will also charge the chassis batteries.
But, if it's a Diesel coach, most of those come with an "Inverter/Charger". And, many of those do not have a converter. The 12V from the batteries cruises right through the system and supplies all the house components. The Charger section of the Inverter/Charger will charge the house/coach batteries. Many DO NOT charge the chassis batteries. There are additional systems/wiring setups that will utilize some of the coach battery charging, to charge the chassis batteries, when the coach is plugged into shore power or, running the generator. Hope this helps some.
