modified Sine Wave inverter question
plan and simple, what has been your experience. with my degree in electronics, yes I understand the difference between a true sine wave and a modified sine wave. I have been running my 211K dish...

Started in the late 1980's with a Heart Interface MSW 1800 watt for our cabined boats and our RV's and never have a single problem with them running everything just like when plugged into shore power. EVERYTHING!
We have been running many MSW 400 thru 2500 watt MSW inverters off 12V DC batteries ever since and still am and have yet to have any TV with lines, items/motors or circuits getting hotter, LEDs not working properly, microwaves, or any of our heated mattress pads or electric blankets not working fine and normal on the MSW inverters.
Even had a fellow RV'er tell me I was crazy since this stuff doesn't work on MSW so I invited him inside and showed him. He claimed I had a mislabeled inverter and it was actually a PSW for all that stuff to run or run right and quiet. So wrong! Finally he agreed that my sealed case MSW wasn't nearly big enough to be a PSW inverter. Then he said it won't run his stuff so I took my spare 2000 watt we carry over to his RV and he attached his wire cables to it and plugged the plugs to his TV in thru an extension cord and then his microwave using the extension cord and Whamo, everything he tried worked just like ours including his wife's electric blanket.
Everything tried worked just like they did on his PSW. Talk about egg guts running down a face, he won the prize and I sure would have loved to have a pic! Then he admitted that everyone told him that a MSW won't run most of the stuff on his RV and he'd believed them and now he felt lied to!
Some of our AC items including the mattress pads and electric blankets are digital and some are analog controls and both work exactly the same on shore power or the MSW. One is now over 20 years old and still works fine. Just bought another electric mattress pad from a Walmart here in Northern Florida in Jan as the old one had a fabric starting to rip apart and the new one works just like the old one did for years now.
I have no reason at all to change to a PSW inverter and cost is not any part of the reason either. My MSW's do work just fine and always have! If they didn't, I'd replace them all in a heartbeat with PSW's. A one time cost! But why?
