Xantrex RC/GS compatible?

We bought a 2011 Tiffin Phaeton 42QBH a few months ago. On our “maiden” voyage bringing it home and the two following trips the Xantrex RV 3012 inverter worked without issue to power the refrigerator while underway. Recently when turning on the inverter the “overload” message and red “error” light reared their ugly heads. After long hours of trouble shooting and isolating every 120v load, I think the inverter has gone to RV heaven. So looking to replace it with the Freedom SW3012 GS, the current Xantrex model. Is anyone aware if the RC/GS controller is compatible or will I need to upgrade to all of the Xanbus gadgets control the same functions? I know our current configuration uses a RJ11 phone type cable and the new system uses an RJ45. While there is an adapter available from Xantrex, I cannot find a single reference to compatibility of the older control panel with the new inverters. After waiting a few days for a call back from Xantrex I figured the wealth of knowledge here would be the next best resource. Anyone else been there and done that?

Let's KISS it first. remove all power sources from the MH then reset the inverter from the front of the unit. If that doesn't work, disconnect its negative cable from the battery bank for 1 hour then reattach and attempt to do a reset.

If that doesn't work either, call Xantrex support. When I called about my now-obsolete RS2000 the technician was very helpful.

Thanks for the reply……….We have tried all of that. Disconnected batteries over night. Load tested all six batteries, cleaned terminals, replaced fuse, isolated each load individually. And Xantrex to date has yet to return 2 phone calls to tech support. Once reset, it will search for a load, if the slightest load is applied, like just opening the microwave door so the light comes on, it errors and gives overload message. Sadly I think it’s fried. Now the question is whether the RC/GS will work a new Freedom SW3012.
