Modified sine wave to pure sine wave converter?
-
Is the Gen Set enclosed and radiator pulling or pushing air vented to outside in that arrangement?

Jon wrote (last week): Today we do not know what devices require pure sine wave and it just seems we find more and more devices that suffer premature failure because they do require it. It is certain more and more devices in the future will require it.
One big problem that I see with electrical components is that when they fail, none of them throw a “fault code” that says “Failed due to MSW”. We can only guess and conjecture what the reason is. Apparently as more and more devices become computerized (you can get advanced degrees from UW-Madison in the science and technology of putting computers into devices that don’t look like computers, popular major, hard to get into, everyone is hired upon graduation) this will be a bigger and bigger issue.

I had one of our two 1999 inverters fail last summer. I talked to Jeff Rowe about the advisability of pulling the inverter, sending to Inverter Services and having it fixed. He said there would be nothing wrong with doing that, until the other one failed or the first one failed for another reason. He put things into perspective for me … inverters are 20 years old, MSW technology and other 20 year old technology (we just put a new Kenmore refrigerator in), I’m going to keep the coach long term, inverters are a critical component of the coach. It wasn’t a cheap date, but I bit the bullet and had him put new inverters in.
Depending on how you use your coach, what is plugged into the 120 volts outlets, and whether you’re handy enough to rewire the electrical when an inverter fails … there might be nothing wrong with stretching out the life of the original MSW inverters.

How difficult is it to change out the MSW inverter to a true sine inverter in a Marathon, where two ACs run off the inverter? I have heard the true sine inverter won’t power the ACs, which is OK with me–I would not mind running the ACs direct off shore or generator power. Whenever we run the CruiseAirs, I run the generator anyway. I am sure some rewiring would need to be done, so how hard of a job, and who would be best to do it?

Per,
The original three transformer heavy MSW inverters were the only inverters that were so well built they could handle the load of AC units.
The inverters of today, while they have the same ratings, just lack the robust construction required to handle such duty. At one of our seminars the folks from Inverter Service Center did an excellent job of explaining why the current versions of inverters are not built for such an application.
I think you are doing exactly the right thing which is to run the generator or be connected to shore power if house A/C units have to be running.
