sounds like you're talking about the converter, not an inverter.
the converter charges your battery when plugged into shore power or a generator. it converts 120v AC power to 12v DC power.
all RV's have converters but few have inverters.
an inverter allows you to run 120v AC items, from your batteries.
I am talking about a power inverter it was installed after market by the guy who had it before me. When power is plugged into the trailer and I switch the battery disconnect switch so that battery power is turned on the voltage on my battery spikes up to around 12-13 volts which then my power inverter works. But it doesn't work when I'm not plugged into power which is probably due to the battery not being good.
