Thor ACE 30.3 Inverter?

[Dan-sr@perra-us.net]

My 2018 ACE 30.3 has a 1000w inverter installed from the factory. I have unplugged from shore power with the generator off and attempted to find something the inverter runs. Then inverter control panel shows 12.5v - 13V but shows no power draw. Refrigerator runs on propane microwave and TVs have no power. I have checked the inside outlets I can reach with the Slides closed and none of them have power. I have yet to check the outside outlet or the one under edge of the bed.

So here is my question, "What is supposed to be connected to the inverter?"

Honestly, I would expect more than just one outlet connected to the inverter I would be very surprised if the outside outlet is the one connected to the inverter and just as surprised if the bed outlet is the only one. If nothing is connected the inverter what is the point of having it?

Are your TVs 12 or 120 volt?

Download and look at your electrical diagrams. They will show which outlets are on the inverter.

You have an outdoor kitchen, I bet the inverter powers the fridge

Yep, the whole purpose of that inverter - the outside fridge. But generally they also power the TV circuits if factory installed and nobody's monkeyed with the wiring.

There have been so many posts about inverters on here. Since I don't have one the only thing I remember hearing about was the fridge

Since it is cold, I didn't even think of that fridge. I have verified, none of the inside 120v TVs are powered by the inverter, also I did not check the outside outlet, the outside outlet in the outside kitchen, the outside TV, or the underbed outlet yet. But if the outside refrigerator is hooked up to the inverter, should I see current draw when I turn on the inverter? The inverter shows 0 current draw.

I don't know that much about inverters except what people have said. The inverter I heard uses more power then what it is running so never figure an item takes 10 amps and I have a 100AH battery I can run it for 5 hours. Inverters use power just sitting there and if it was left on for a long period it can run the battery down, that's why most of them have a switch or Bluetooth to turn them off when not needed. If you don't have an amp probe you could use your meter to see if there is a draw. Most average meters have a 10 amp limit on them

What do the status lights show? Do they change when connected to SP or not?

Yes, when connected to SP, generator, or engine running inverter control panel usually shows something a little over 13.5v drops to a little under 13v when unplugged engine and generator off.

STATUS LIGHTS not voltage.

I have read my THOR manual, and they are vague of course sending you to the owners manual. Time to take out the voltmeter and check every outlet. Seems like alot of trouble to install an inverter for just the outside refrigerator. Please list what outlets have pwr when just running on inverter pwr, for the next owner asking same question.

I have installed an 1000W inverter and have one dedicated outlet for one TV and wired it into the refrigerator circuit for pwr while driving. I also labeled it so, for the next guy...the second white wire is for a night light on my table to indicate to me when the inverter is running.

According to the Schematic Thor sent me 120v circuit 5A is powered by the inverter. The outlets in this circuit are:

1. The dashboard workstation outlet.
2. The outside TV outlet.
3. The Bedroom TV outlet in overhead.
4. The outside kitchen refrigerator outlet.

I have a 50amp coach this information does not apply to a 30amp coach. So far, the only outlet in this list I have checked is the Workstation outlet and I found it had no power with shore power disconnected, generator off, and inverter on. I used an analog 120v AC "Line Monitor" that I have had for years to check. It does show power with shore power connected. I would not be surprised if it does not work with the output from the inverter.

I have not had an opportunity to do any additional investigation because of an incident with a large chunk of truck tire tread that ripped the tail pipe off the hanger and pushing the tail pipe under the rear tire causing the exhaust system to be pulled down onto the drive shaft and bending the drive shaft.
