Yes I agree but as you probably know these kind of threads end up this way as everyone pitches in a little here and there and the resulting questions and corrections follow.

Buy and inverter with enough capacity. 2000 watts is a sweet spot. Install it, then plug in the shore power cord. Set the fridge to propane. Turn off the converter.


Turn on the inverter and enjoy the RV appearing to run on shore power anywhere.

Inverter Power

To power a 120 volt 1200 watt appliance you the inverter will need about 150 amps at 12 volts DC so the DC wiring and house batteries would need to be sized for that.

Be sure to select a pure sine wave inverter if you want to power a microwave or most modern electronic devices

Well, all of this discussion is fine but why has everyone ignored the fact that the OP is asking about his 18’ Travel Trailer that likely has one group 27 12v dual purpose battery with maybe 65ah of storage… approx 35ah of which is useable.

This TT is not going to run a 1500w - 2000w inverter for any length of time regardless of the wire gauge used. Nor will it so much as start his microwave.

The OPs question is a good one, but the answer is: that TT, setup as it came from the factory, is not really capable - without a number of changes to the battery bank and electrical system - to power heavy duty 110v appliances such as a microwave without being plugged into shore power or a generator.

While his TT COULD be modified to do this the cost would be a couple of thousand dollars. For far less a small portable generator would provide the power he needs and provide the ability to charge his one house battery as needed, too.

For 3.2 seconds before the Low Voltage alarm beeps and the inverter shuts down.

Yeah, thatíll work.

Creative part is right on the mark in his last two posts. Even though I hate hearing generators running for long periods of time, running one for a few minutes to power a microwave is OK by me.

I have an inexpensive 1000W inverter and I doubt I've used it more than four or five times over the last ten years. We have used a smaller inverter that we've used so my wife can power her sewing machine. We're just not tied to the need for 120V AC when there's no shore power.
