"The batteries are fully charged and my 110 outlets will not work with the solar. I am wondering if there is a fuse somewhere else in the trailer, other than the fuse/breaker panel or if I have a problem with the transfer switch, maybe? I'm asuming the problem is inverter-related, but not sure. I have the 320 solar watt package, with the Xantrex 2000 watt inverter. The batteries are fully charged and my 110 outlets will not work with the solar." is this statement true...batteries at 100%, you are not connected to shore power and your 110 outlets don't work....but your inverter is ON? Here's a checklist to help: Battery Charged (YES) Connected to shore power (Yes) (No) Inverter On (Yes) (No) Fridge Breaker Tripped (Yes) (No) = ours has a 20amp breaker in the panel for the fridge Inverter Built In GFCI Tripped (Yes) (No) = There is a plug in on the actual inverter that has a GFCI on it...see below GFCI In Outlet Tripped (Yes) (No) = Our hull has a second gfci outlet on the front of the dinette seat.

Typically it's a GFIC receptacle (outlet) with a reset and test button, not a breaker. It will be the first receptacle closest to the breaker panel that daisy chains to feed the others, mine is the one under the dinette.

Thank you katanapilot and Ronbrink. There doesn't appear to be any CB tripped, but I could see it being the CFCI breaker. Where is the breaker for the inverter located? I don't see a CFCI breaker specifically for the inverter. Also, unforturnately we don't have a microwave.

@ScubaRx had a great idea. Go to the truck fuse box and disconnect the fuse that provides power to charge the Ollie batteries (I am installing lithium batteries in the Ollie). A great idea to pull the charger wire fuse so there is no power in the line at all to the 7 pin connector. Unfortunately on my 2024 RAM there is no such fuse for power that would charge the Ollie batteries. The 2024 RAM fuses for the trailer are (1) Trailer tow backup; (2) Trailer stop/left turn signal, (3) Trailer stop/right turn signal, (4) Trailer tow park lamp. I guess I would have to remove the wire from the "Aux 12V Power" connector at the 7 pin connector, if I want to stop power from my vehicle alternate to not charge the Ollie batteries or find the wire in the Ollie to disconnect, but then there is still power in that wire. @Galway Girl and others that have converted from AGM batteries to Lithium batteries: Is the "Aux 12V power" on the 7 pin connector the wire to disable? Can the vehicle charge wire to the trailer stay in place when installing lithium batteries? Will the vehicle alternate be compromised if the wire is not disconnected? Thanks All

A good way to check if the GFCI on the inverter is working is to see if the microwave has power, since it plugs directly into the GFCI outlet on the inverter. If the microwave has power then your inverter is working. If not, the GFCI has tripped and needs to be reset. For reasons unknown my GFCI has tripped, wherein the microwave and outlet receptacles have no power. There have been times when it took a few presses of the reset button on the GFCI to get it to work again. Once power is confirmed at the microwave, all is good. This may not be your remedy, but a good place to start.

I have extensive experienece with carbon fiber vs alloy aluminum for structural components under heavy load. Specifically in critical components such as hang glider frames. I have many times put my life on the line with them in that sport. They are strong and reliable... until they are not. When they fail, the consequences are generally been dire. This happened to two of my free flight friends. They died. The problem is that carbon fiber components are extremely difficult to inspect for tell-tale structural failure. With aluminum, for most spars, we see micro crazing then small cracks. They grow as the structural intregruity deteriorates. I no longer fly or use carbon fiber for life safety applications. The reason is that the inspection technology to ensure they are still safe to use is way way beyond what the average owner can do at home or in the field. GJ

Solar can charge the batteries (12 volts DC). Batteries can run the inverter (12 volts DC converted to 120 volts AC). Inverter is a pass through of 120 VAC when on generator or shore power. Inverter is also a converter and will provide 12 VDC to charge the batteries if AC load allows. Solar cells do not provide AC! If the batteries are charged, the inverter is turned on, the GFCI on the inverter is not tripped and the CB in the main panel is not tripped - the AC outlets in the trailer should operate. If the outlets aren’t working, check the GFCI on the inverter and the CB on the main panel under the dinette. Wire plugged into the GFCI feeds the AC outlets through the CB.

Off topic. What area of Wisconsin? Door County here...

I'm sorry we got off track here. The first reply after my post said "Your outlets will only work with shore power, a generator, or with an inverter turned on if you have one." I replied our inventer is always on when using the inverter. I should have said my inverter is always on when using the outlets. But then the discussion turned to why not to use the inverter full time and away from the original post. We were out on a long camping trip, when this happened and it was the last BLM spot we camped in. I am home now and want to start working on the problem. The batteries are fully charged and my 110 outlets will not work with the solar. I am wondering if there is a fuse somewhere else in the trailer, other than the fuse/breaker panel or if I have a problem with the transfer switch, maybe? I'm asuming the problem is inverter-related, but not sure. I have the 320 solar watt package, with the Xantrex 2000 watt inverter. Looking for any ideas. Thank you!

Ditto. There have never been any Oliver dealers in Wisconsin or anywhere close to me. It is almost a draw between the closest out of state dealer and going to OTT in Tennessee. I am not complaining as I understood this when I bought the trailer. My solution: I found a reliable RV service center (and dealer of other brands) in the state that is also an authorized Truma service center. They work well with Oliver, Truma, Xantrex, etc. They did a couple of warranty repairs for me with no issues and Oliver providing reimbursement (Thank you Jason E.). If I need other repairs, I will go back there. At one time, we discussed having an informal Oliver service center directory. I understand there may be some implied endorsement issues with having that posted here but it sure would be handy (assuming everyone understood the ground rules).

All the comments are right on the money. But for a little more perspective of why you fell short of power, consider this: My guess is that you have about 400 Amp Hours with your 4 AGM batteries, which gives you about 200 AH usable power without going below 50%. You stated that your inverter stays on. A Xantrex Freedom inverter uses 72 AH per 24 hours of standby power (turned on without a load.) The Victron Multiplus is better at 40 AH a day with standard factory settings, and as low as 16 amp hours a day with power saving settings. These are both zero AH when turned off. The batteries are being supplemented with an assumed 320 watt solar system, which is under 30 AH a day in sunny conditions. You mentioned a coffee maker which burns a lot of power, typically about 20 AH to brew coffee, and more if your keeping it warm. That could cancel out the solar contribution. Now add in the AH values for whatever else you're using, and you can figure out how long you can last when boondocking. Hope that helps! Cheers, Geoff

Thanks, Geoff :)

Yes, in an OTT installed system, yet we keep our Victron system on always, 24x7x365! It’s ON now, as we sit on our deck with A/C set to 85F to keep things nice! Solar on/off has nothing to do with 110VAC outlets working, PERIOD! We could only guess, not knowing battery, inverter or any other particulars.

Inverter should be off unless using microwave, outlets, or watching TV

Reached out to the Texas dealer i purchased from in February 2025, he could not answer my question on what happened to Oliver dealerships in Texas and could not advise me on how to get any info on service needs for warranty issues. Also, Jason has not bothered to respond to my msg request of the same concerns. So much for quality of communication and support. Very disappointing in many ways.

Yep, familiar with them. Didn't know they were doing composite frames, though. I've been inside a couple of their trailers before, wasn't too impressed. Very small, but it looks like they've upped their game with a 22 footer now. Interesting. Surprised it's a single axle!

I recommend you leave your inverter off until you need to use 110, especially with AGM’s. As mentioned above, just having your inverter on and not being used draws down battery capacity. We rarely turn our inverter on.

The batteries are back to fully charged. They went to down to around 50%, when this happened, but back to 100% now.

Cortes Campers - Here is the link to their announcement

If your batteries are too low of voltage < 10.5v the 2000 watt inverter shuts down. the inverter should alarm on low voltage or give an E01 code. when you are in solar if the batteries drop too low the inverter will not turn on again until the batteries are charged When we boondock we leave the inverter off unless we need 110 as it draws down the batteries just being turned on. if you fully charge your batteries the inverter should begin working.

Interesting. What's the new company with the CF frames?

Wonderful information is flowing like Niagara Falls... I can barely swim and I see the 'mist' going over the edge, I went to the www.airforums.com out or curiosity. Checked: Running Gear- Axles, Brakes, Wheels & Tires. Went to Brakes and Brake Controllers: (The following is a cut and paste. A very nice job. I have a Bargman on the Oliver Elite II presently... just to update FYI.) Airstreams have identical issues, which does not surprise me. I have been lucky with mine buying new off the lot and checking it over before closing the deal. Although Airstream may sell hundreds every year and have thousands on the road. All operate the same kind of electrical brakes. Not good to hear. ************* My cut and paste********** Check your Trailer connector! Unless they have changed, for some reason Airstream uses Bargman (?) 7 pin connector on the trailer pig tail. These double contact ("duck-bill") connectors do not meet the SAE Standards and DO NOT play well with most of the OEM 7 pin sockets that meet the SAE Standard. It is such a problem that I believe all of the big 3 have put out bulletins over the years. Here is a bulletin that RAM put out --- https://www.ramtrucks.com/BodyBuilde...2BI1n%2Bn9n%0A I have that one as I drive a RAM 2500 Cummins. I switched my the connector on the end of the Airstream (2019) to a Pollak 12-706 and all messages about trailer brake disconnected and intermittent problems went away. These Pollak connectors are less than $8 on Amazon and it only takes a few minutes to cut the old one off and wire up the new one. The weird thing was this intermittent error didn't show up at first. However, once it started it progressively got worse. Its been over 2 years now since I changed the connector on the Airstream and have never had an issue since.

I have four AGM batteries and the inverter is always turned on when using the solar.

Your outlets will only work with shore power, a generator, or with an inverter turned on if you have one. More information is required. What batteries do you have

My 110 outlets are not working with my solar. Everything else works fine; lights, refrigerator, water pump, etc, but no 110 outlets. The outlets work while plugged into shore power or with the generator. This started when I was boondocking and did not notice my refrigerator was still set on DC, from traveling. When I went to make coffee in the morning, the electricity started struggling and eventually went out. I've checked all the possible fuses, breakers and GFCI plug, and all seem to be good. Is there a fuse for the inverter that is located somewhere else in the trailer, or could I have maybe fried the transfer switch? Thoughts? My trailer is an 2018 Elite II.
