Xantrex went crazy after transfer switch replaced

We had a major water leak that ruined the tile floor in our 2004 Alpine. We had it replaced and it looks terrific. However when we went to pick up the unit, the Xantrex was flashing and we had no 110 power. The repairman determined that we needed a new transfer switch. After he replaced it, we had 110 power again, but the Xantrex is still flashing and the inverter will not stay on. So we had new batteries installed, (the old ones were bad). The Xantrex still is flashing.

Has the repairman incorrectly installed the transfer switch? Was that the problem in the first place? All was working fine prior to his replacement of the floor tile.

We were leaving on vacation yesterday and now am sitting in limbo. Where can I go for help?

Maybe the Xantrex needs a reset?

That might.... Actually.... be true.

There are a couple of possibilities including bad transfer switch install epically on 50 amp rigs.

BUT try this.. Remove all power.. Disconnect (Physically) the batteries (lift negative lead) Unplug from shore power. and if there is a master ON/OFF on your model turn it off (First).

Enjoy one already brewed cup of coffee or one already chilled "Cold One".

Now re-connect, plug in and turn on

See if that "Rest" made it reboot.

Finally,,,, Check to make sure 120 volts is reaching the unit... I have seen

Tripped breakers
Loose screws (Circuit breaker/bus bar)
Loose screws (Marinco Inlet/outlet)
Loose screws (Shore plug)
Loose screws (Shore outlet)
Bad wires (This only in 12 volt systems on my coach)
Bad connections...One of those was inside the junction box on MY Xantrex Prosine.
Home is where I park it!

Agree--if "everything works on shore power" then the new transfer switch is probably working. Whether you actually needed a new one or not is another question. Short of getting another "professional" opinion, about all you can do is push reset buttons, disconnect/reconnect power, and check for loose wires. Assume you are not getting any fault codes or warnings on the Xantrex display?????
PS-- So how big was the "major flood"? Did the Xantrex get wet? Right now, you have a new x-fer switch and new bats, neither of which appears to be the root cause of your problems.

Be sure when you disconnect all power that you include the solar cells, they supply power any time the sun is shining, even if the negative is removed from the batteries.
