Bad transfer switch which one to get

I have a bad circuit board in my transfer switch on a 2018 cornerstone when I search this part there is a version 1, 2,3
Has anyone had any experience replacing this and how do you know what version to get to work with current software in the main panel? Or does it not matter?

What’s the difference between 40350RVC, 40350RVC1, 40350RCV2?

The 40350RVC and 40350RVC1 are the same product. The 40350RVC2 has a different configuration of strain relief/topaz connectors.

Surge Guard 40350RVC3 50 Amp Hardwire Automatic Transfer Switch
The Surge Guard 50 Amp Hardwire Automatic Transfer Switch provides enhanced features over other models and continuously measures shore power to switch to generator power when shore power electrical conditions are beyond limits.

I replaced the OEM 40350RVC with a 40350RVC1 in my '18 Anthem and it has been compatible.

They can be a challenge to locate and I see the RVC3 is a little more expensive. New and improved = more expensive, I guess.

Take care,

I would be curious if any advantage to replace both inverter / charger & transfer switch with a Victron that supposedly does all 3 tasks.

Might get the added benefit where Victron says their inverter will boost shore power with battery if needed. Don't think my current Magnum will do that.

Just an extra bit of stuff to think about.

The OP's '18 Cornerstone is equipped with two Magnum Energy 3,000 watt Pure Sine Wave Inverter/Chargers (MSH3012M).

The MSH3012M has this feature:

3.2.2 Load Support
While in the Standby Mode and the charger is enabled, the MSH-M Series inverter/charger has the ability to work in parallel with the incoming AC source to support the AC loads using current from the batteries. During the Standby mode, the current and voltage from the AC source and the AC load current are continually monitored. When loads that exceed the available current from either the shore power grid or the generator are connected, the Load Support feature is automatically activated. The Load Support feature causes the MSH-M inverter/charger to reduce/stop the battery charging operation and begin the inverting operation to allow any available current from the batteries to be used to ensure the AC loads are powered and the current does not exceed the capacity of the AC source, or trip its output breakers or fuses. The Load Support feature turns off once the load demand decreases and spare power from the incoming AC source is available; when this happens, the battery charger is again activated and begins charging the batteries.

Also, I wouldn't be surprised that there would be challenges with the interface of the Victron inverter/charger with the VegaTouch control system.

Take care,

I get the impression that you are the kinda guy that actually digs out the manuals in the "Bag-O-Manuals" in the closet and ACTUALLY reads them !! You are going to become my Go-To Guy when I need technical information that is probably contained in the paper manual that I got with the bus but never bothered to read because I've never had problems with whatever it is that I am now having problems with before.

How about sending me your cell number back-channel just in case I need some technical information in one of those manuals! __ I'll give you a ring....

Gary, I’m honored that I’d be considered a “Go-To-Guy” by you.

Actually I really don’t like to spend a lot of time with paper manuals. I do, however, find great use for searchable .pdf files. I’ve downloaded a library of documents to a laptop that I carry in the motorhome and also value an internet connection; I’ve found Google to be a useful tool. For me, the laptop is so very much better for document search than a phone or tablet.

My adult professional career flying large aircraft, often for many hours in remote locations around the world, left me with great respect for deeper systems knowledge than most people have. Although we usually had a capability to “phone a friend”, there usually wasn’t much the “friend” could do beyond suggest that it sucked to be in our circumstance. IF we couldn’t solve a problem, the situation could deteriorate.

I’ve found my RV life to present similar challenges. Some systems knowledge can solve many of the problems that pop up along the way. This forum has always been a wonderful resource, as well. There’s such a breadth and depth of wisdom available here (you’re a major contributor to that resource).

I’ve always embraced the “teach a man to fish vs. give a man a fish” philosophy and in most of my contributions here, I try to take the form of providing some documentation on which I make my suggestions. My hope is to nudge folks to dive into the books. That’s probably a result from thousands of hours as an instructor pilot, trying to instill into my students the wisdom of finding the answers to their questions through their own research rather than just having someone spoon feed them the answer.

Take care,
Stu

P.S. Several years before I retired, my First Officer asked what I planned to do in retirement. I responded that my wife and I thought we’d buy a big motorhome and drive around the country. I really do enjoy travel, just not hotels, suitcases, etc. He responded that his parents had had motorhomes for years and that they loved the RV life. Then, he asked if I liked to “fiddle” with stuff. He assured me that there’s lots of stuff in a motorhome and something always requires some degree of “fiddling” to make it work right. I’ve found that to be true and have been blessed with a personality that enjoys “fiddling with stuff”.

P.P.S. Phone number to follow by PM.

You are very kind to send me your number back-channel, and it is now on file for future reference.

It has really been obvious that you support many of your posts with quotes from the "source" and that is always useful for novices and old-timers alike. You do it well, and please keep doing it when you can. Its part of what makes this forum so dang helpful. I've spent my professional career largely with my nose stuck in journals which answer important questions but I have found that learning these coaches is a matter of "locking horns" with the problem, reading sites like this forum and info found with a good Google search has been a different process, and the other people who post on here tend to almost always know what they are talking about. Both processes are important, and thank you for what you do.

I won't abuse the number. I'll also send mine back-channel to occasionally return the favor if I can ! And an HP laptop augments the iPad and iPhone in this bus. All are essential !

Cheers!

I guess my question is I know the version 1 will work but very tough to find. the version 3 is readily available and I’m fine with the added cost as long as it will work with the current electronics. I have a guy from entegra checking with fire fly to see if it’s supported. But I figured I would ask here to see if anyone has been here before.

The RVC3 probably fixes what causes the RVC1 failures

But it is still one and done, and not repairable. It just stops surges from entering the MH, but only once. One reason an Energy Management System before the transfer switch is so important.

Mine went bad and I use an external surge protector. Someday I'm gonna replace it

External is better than nothing. If yours that went bad is a Progressive, they have a lifetime warranty. It's just a board replacement.

The onboard went bad while I was using an external, my external is a Hughes...

Hughes is diy replacement if board goes bad.

Onboard has surge fault...not repairable

[STEVE-JUNELL]

Our issue was a bad circuit board in the transfer switch not letting the network through it. So we replaced with 40350rvc3 version 3 and everything is working with current software !!
