Re: 1500 W 12V Real Sine Wave Inverters?

I've installed a few of these and this is what you need:

Really good, less $ than Mastervolt and probably a better fit, especially since the charger operates over the entire sine wave giving no lagging power facter that requires de-rating the power that you can get from 30A shorepower.

Re: 1500 W 12V Real Sine Wave Inverters?

nd the MagnaSine 20/12 is $1700 ?!

Their MM series at $700+ isn't as shocking, but after I found out that Xantrex sells simple square wave products as "Modified Sine Wave" (what a load of bunk) I'm almost afraid to ask Magnum for the story on what their MSW really is.

Long thick power cords are looking better all the time.<G>

Edit to the last msg; I said "simple" square wave, but probably should call that "modified" square wave, since there are flats between each wave, not just up-and-down square wave. Still, spaced out regular and uniform square waves ain't sine waves in my coloring book.

You should just steer clear of the "oh no, not the X" brand. I know that a good story exists for every bad one, but that still means 50% of owners got frakked while these stories are non-existent with top brand sine wave products.

If I would buy anything less than a Victron, it is the Sinergex. I might even consider Outback, but not Magnum. There you have it: where the line is for me

ciao!
Nick.

Re: 1500 W 12V Real Sine Wave Inverters?

Nick, I'm almost ready to start looking for circuits and roll my own, as an alternative to smoke and mirrors. At least when my own creations emit smoke, I know who to blame for it.<G> I do indeed have a kilowatt adjustable "12" volt power supply, did blow one of the power transistors weeks after building it, corrected the problem, and haven't had any issues since. So when these companies tell me how incredibly complex, difficult, even impossible some things are....uh-uh. I'm reasonably sure I could add a waveform generator to the regulator in my power supply, teach the bootstrap transistors how to sing a sine wave, move the power transformer (oh yes, analog) to the other end of things, and funny thing, it would do the job. Adding frequency stabilization and all...still not rocket science, I'm sure Shenzhen's already done it.
Somewhere in between "You want how much?" and "Please don't laugh when I say warranty" there's bound to be a solid choice.<G>
I'll keep making haste slowly and try to find that one.
