So how i am looking at those plugs as wired directly to the inverter...or did i miss something?
If you've chosen a Danfoss-based fridge like the Vitrifrigo or the Dometic Tundra or similar, you're home free there. A 120v TV will need to be powered off the inverter if you don't have a shore power connection. If you think all the plugs are (in their original configuration) connected to any sort of inverter, you're missing something. It's certainly possible to wire in an inverter for them as a modification, or to add a dedicated inverter plug or two. Are you looking at an original wiring diagram or a design document from some solar proposal? Perhaps you're confusing the converter-charger (Univolt) with an inverter?

Another alternative is to find a 12v DC TV, there are a few but there's much better selection in the 120v AC sets.

Our 2013 25FB International Serenity had the factory installed 600 watt inverter. The two TV power outlets and one under the dinette were the only ones that got 120Vac from the batteries. Our dealer installed single 150 watt solar panel could NOT bring the batteries to a full charge with full sunshine all day after the furnace ran at night at the Albuquerque Ballon Festival last October. We had to run the Honda 2,000 watt generator about an hour to get the batteries to 100% capacity for the next night's furnace run.

We ordered our new Classic with only the 50 amp service upgrade. Thus all the trailer's 120Vac outlets lack power when the service cord plug is pulled from the service pole beside the trailer. Everything has to run off the batteries at 12Vdc and or propane.

Now the Classic is undergoing a major solar system installation that includes eight 100 watt solar panels with a Magnum MS2812 pure sine wave inverter/converter and a TriStar 60 MPPT solar charge controller connected to four Lifeline 6Vdc 300 amp hour batteries. Every outlet will be energized on both shore power and battery power.

I will have to manually select the propane option for the refrigerator rather than the automatic mode and even the air conditioner(s) could be run for a few minutes for a lunch stop beside the road.

Having said this, the installation and parts are expensive. During this process, the trailer will also acquire disk brakes.

Ok. So in answer to the question of the solar person designing this system it would be me. And i have no idea what i am doing...luckily i have you all to help.

So the next question is this..

Where is this wiring diagram for the 1976 trade wind. I would love to see it.

It will seem a lot more practical to wire the outlets in the RV directly to the inverter, since i prefer them to be off of the solar batteries than to rely on shore power. I plan on doing a LOT of boon docking.

I have a Dometic fridge that runs off of propane and electric, and a Girard instahot heater that runs off of propane.

the only major appliance i am looking at for the inverter would be the fridge (sometimes) and the TV when it is on...

I have not found any 12voit tv's with the USB movie player and the built in Wifi. So the Samsung is a good price at the costco...so it is the winner.

Thanks for the advice regarding the batteries...sound like that is what i will be doing with 2 golf batteries from the costco...

I am planning my first small voyage this week and when i reach my friends house i will be completing my floors and my solar system.

We have

2 144w panels
1 30 w MPPT charge controller
1 1000w passthrough inverter
2 6 volt interstate costco golf Cart Batteries.
30 ft of 10g cable
a ton of pure patience
and pic when done.

did i miss anything???

A battery monitor,such as the Trimetric TM 2025RV or the newer TM 2030RV so you can really see what your batteries are up to. See " Bob's Solar Blog" for reasons why.

This link to a solar system primer might be of interest in filling in any knowledge gaps:
