Live outlets with inverter

Is there a general pattern for what outlets are hot when inverter is on or do I just need to plug something into each and use trial and error to discover? I know generally the front media center is hot and the mid tv. Are GFI's generally connected as inverter circuits?
  • Hi,

    If it came with the inverter from the factory the only way would be to check each outlet--unless it is specified in the owners manual.

    GFIs should work with the inverter......I will say tho that I have 2 inverters and the GFIs didn't work when #2 went bad.

    What are you running?....someone will have a similar setup I'm sure.

  • All my inverter outlets were tagged as such. If yours are not, then it's trial and error. I'd put a small mark on each one (think felt tip perm marker) so you don't forget in the future...Dennis
  • GFI circuits are generally connected to the inverter. In my coach the 2 outlets on each side of the bed are not connected to the inverter, All other outlets are connected including the microwave as a pass through circuit. Don't know if it's true or not but I was told the reason the 2 outlets in the bedroom are on shore or gen power is the MSW inverter wave form will destroy electric blanket controls.
  • Thanks for the quick replies. Winnebago Suncruiser 38q. I have had inverters before and just did trial and error. Marking them is a great idea. Maybe I should change faceplates. Somewhere I herd the Gfi's were usually on the inverter.mi learn a little more with each motorhome. With residential refrigerator I will make greater use of inverter as it has more capacity.
  • Depends on the type of coach and the size of the converter. For most smaller, lower cost mass production RVs the inverter is for a few entertainment outlets, so they can be powered by the engine alternator output when under way. Inverter is usually 1 kw or smaller.

    In many larger coaches, the inverter is 3-8 kw or larger, powering every 120 V outlet when you are not plugged in or running the generator, might be feeding from 400-800 pounds of batteries and 200-400 amps of alternator output, and backed up by an auto-start generator when batteries start to be depleted.

    On your Sunrise, it is most likely the entertainment center version of inverter power.
  • It depends on the size of the inverter. Most coaches have a standard size with options for larger inverters. On my 3.5K inverter, it powers all of my outlets including the microwave. The standard 1.5K does not power the microwave and only half of the coach outlets. A GFI should make no difference in the outlets that are powered since it just looks like another outlet to an inverter circuit.

    I don't see 2016 wiring diagrams up on the Winnebago website yet, but here's the Body, 110 Volt Wiring Installation/Diagram for the 2015 Suncruiser 38Q. If you check the wiring diagram on the last page it will tell you which outlets are on the inverter.
  • My little Class C has a 300 watt inverter and only powers the 2 entertainment centers. Some larger RV's have 1k or 2k inverters that power most or all of the whole rig. Many are somewhere in between. Testing is your friend.
