Generic info:
Iinverters come in 2x2.sizes types
First division
True sine wave or Modified sine wave. True is by far the best.. In the old days Xantrex, who makes both, had a document on their web site titled things that may not work properly on MSW inverters.. It was a LONG list of things and growing faster than they could update it.. Even LED nightlights are on the list believe it or not.
TSW (Also known as Pure Sine Wave) the list was much shorter.. In fact it had only one entry (Common to both lists by the way)
EVERYTHING, even my most sensitive radio receiver works just fine with the TSW inverter on and working, ONLY thing that ever gave me a problem was a deffective to began with coffee pot.. It has since been replaced..twice. (First replacement wore out, I'm a coffee-holic don't you know)
Now, to the comments:
Some of the MSW inverters out there are el-cheapo pieces of .... Avoid them.
But when you get a True Sine Inverter with a decent 3-stage charger module... I've yet to see one of those that was crap. All were well designed. Of course with the influx of China products.. that may change some day soon, or not.
