Installed inverter & solar, now what?
Before hitting the road as a full time RVer in our 35' A gas Winnebago I installed a 1500 watt MSW inverter, 400 watts of solar power with charge controller and Trimetric meter. I have one new outlet in the kitchen that is connected directly to the inverter. I have no other way to take advantage of my efforts. I am installing a residential refrigerator this week and would like too get power from the inverter when traveling. Is there a device that allows the inverter to be automatically selected as power source when no other power is available?

Apparently your inverter does not have an internal transfer switch? If it did you could install a subpanel and route the output if the inverter to it. The subpanel would have breakers for what you want powered. If the inverter had a transfer switch, when your on shore or generator it would pass the power through to the subpanel. With out shore power the inverter would power the subpanel. Or you could do at member vsheets did with his system.

Yeah, it is just a basic Xantrex inverter that I bought on sale at camping world. I never thought I would really need it. I just put in for the heck of it, then did solar. Each does what it is supposed to do but nothing more.

You could install an external transfer switch to have the inverter power the refrigerator. I found the attached PDF of a transfer switch made by Xantrex, might give them a call to see if they still make it. Here is a link to the transfer switch.

Thanks, I'll start searching for that/a transfer switch and schematics.

Thanks for sharing your video, thought I needed whole coach wired to transfer switch. Your project changed my understanding.

You say that you will be installing a residential refrigerator and plan to run it off a MSW inverter, I thought that it would require a PSW inverter.

Most refrigerators work with MSW inverters. Tiffin uses GE refrigerators with MSW and Samsung verifies some models work with MSW.

The fridge is a magic chef. They say no inverters and no RV so I am on my own. It is installed and working well on shore power. Guess I could put in a small dedicated PSW just for the fridge with a dedicated transfer switch. Learning as I go,

FWIW For parts I would talk to an Industrial Electrician or electrical supply company. All the transfer switch really is is a relay run off 120VAC. The industrial control folks do the same thing routinely to control motors. An enclosed Double Pole Double Throw (DPDT) contactor in a box is what you need. Industrial Control folks use contactors, electronics folks use relays and mechanics use solenoids. All the same thing but you sometimes need the correct term. ;-) From what I have heard around the refrigerator draws less than 200 W or ~ 1/3 HP. Probably the smallest parts they have are rated higher. If you really want to switch the neutral 3PDT contactors are routinely used to switch 3 phase so should be on the shelf. As I said, all you need is a 120 V coil and a voltage rating over 120 VAC. There is a lot of 440 and 660 3 phase around so anything designed for those services will work.
