Jayco ceiling fan

You are looking for an inverter/charger that will run your outlets, etc. It takes the place of your converter and it is pretty expensive and has about 8 other components that go with it. We installed a sub panel and moved the outlets including the microwave over to the sub panel so they can work using the inverter or on shore power. You also need a transfer switch, battery heat detector, inverter monitor, and a whopping big fuse. Most factory inverter installations (usually in motorhomes) only have a few outlets dedicated to the inverter where we have all our outlets with the exception of two of them wired for inverter use. We have a 5th wheel and have 4 Group 27 12 volt batteries. Using an inverter really uses lots battery power. May we ask why you need power overnight when sleeping? The ceiling fans will work on 12 volts so you can run them. fridge and water heater will run on propane so no worries there. If you are thinking of TV watching, you can buy a small inverter just to run the TV but that will not power the other outlets.
