12 volt inverter.
How many volts should an inverter put out when hooked up to shore power. if batter is good . Then how much if the battery is low.. Trying to find out if inverter is working,, old battery died and ...

Some RV's have a converter, which converts 120vac to 12vdc
Some ALSO have an inverter, which does the inverse (of course) making 120vac out of 12vdc.
Some have an Inverter/Charger (the charger is a converter) which does both depending on the presence of an alternate source of 120vac (Shore or generator) I have all 3,, though not all are hooked up (The Inverters (I have 3 or 4 of 'em) are buried somewhere not connected).
Now.. output to the battery, as measured AT THE DEVICE (Converter or inverter/charger) as others have said 13.5-14 volts to charge. To find the specific voltage read the manual, if you do not have the manual find the make and model, Example Progressive Dynamics 9280, and google it with the word"Manual" following..IE: Progressive Dynamics 9280 manual.
IF measured at the battery, and the battery is FULL 13.6 (Same at the converter)
If measured at the battery and the battery is HUNGRY, it will be lower, but may be HIGHER at the converter.. I know this sounds strange but the reason is the resistance of the connecting wires. Which in the case of my rig, are LONGER than the RV!!!! (Well from the 9180+wizard to the batteries,, From the prosine, about 2 feet of 0000 gauge wire)
