120V AC and 12V DC systems ARE already separate.water pump, Lights, Fridge/Water heater Propane controls, fans, etc
As Biscuit said they are different systems The ONLY common point is the converter or Inverter/Charger
Converter: Converts 120 volt AC to Battery power. (13.6 to 14.6 VDC) charges batteries..
Inverter/Charger: Does above if shore/generator present. else it does the INVERSE (converts battery power to 120vac) Not all RV's have one.
I have both
YOu may skip this next part:
12 volts may be used by some 120 volt stuff for CONTROL.
Examples include Fridge, Water heater and Air Conditioners
Back to read on:
If the Converter or charger is ... toast.. you may hook up a SMART charger as a temp measure (just hook it to the batteries) Mine is a Deltran Battery Tender PLUS. the unit I have can do 1-2 amp Tend. 20 Charge and 70 Jump start. about 100 bucks at AutoZone Works well
(My converter failed in 2017, my inverter as well so I had no 12 volt once the battery died.. on a Sunday.. AUTO ZONE Was open so I had power back quickly. Replaced converter 2 days later).
Finally converters for this post come i 2 flavors. ONE is integrated into the power distribution panel.. LIke a Parallex 7300 or some WFCO models.. IF you have this type and have confirmed the converter is toast go with a Progressive Dynamics 4600 series. it replaces JUST the converter part.
The other is a Stand alone (Independent box). And to replace that a Progressive Dynamics 9200 is the box of choice
Mine is a 9180 with charge wizard (Equal to 9280 with dongle).
