DSDP Don,
You are so right about thew MSW in very expensive MH's and always worked fine. WOW! How can that be??? Some know the truth of having actually used MSW inverters and a few maybe not so much as they haven't!
I'd forgoten to include the 3 MSW inverters we had in our 3 big Allegro MH's we had owned. They sure did run everything connected to them and I've never heard of a single problem with any eletronic items etc not working or being ruined with them. Yes, it was a good 10 years plus of industry wide and owners using them without issues experienced and long before PSW inverters were ever installed, used, or available.
Lets hear from the naysayers posters giving some real answers rather than just saying people who use MSW inverters don't know what they are talking about! Thousands upon thousands of real life experience with using MSW inverters already in the books and well documented but the few say these many thousands are so wrong! DUH!
