inverters, pure sine vs modified sine?

Hey all....Just wondering if anyone knows the difference?...I am needing an inverter for 3 game consoles, 37" lcd and a 23 inch LCD tv for my tahoe project....I wanted to get a Vector Maxx SST 2000-3000 watt inverter, however come to find out that they use modified sine wave technology and I am hearing rumors about lines on peoples tv's and consoles in their vehicles from this.....Now I saw a post here about PURE SINE technology and supposedly it solves this issue....I don't want noise in my audio system at all.......So some professional advice here would be awsome cause I know the PURE SINE inverters are like twice the price...but I dont care cause I want whats better but I dont want to go overkil if I dont have to...Also is 3000 watt tooo much for what I'm doing??....Thanx

Ture sine wave will assure as noise- and trouble- free an installation as possinle, ESPECIALLY with the video devices. IF the inverter is a higher quality MSW, then you might be able to use it still. If the output is a single step MSW, look elsewhere. Some manufacturers will tell you how many steps their outputs are, the more the better, and will likely still be a bit less expensive than true sine wave. True sine will cost significantly more, especially in the power ranges that you are looking for, probably 50 to 100% more.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

So how many watts would you recommend for my setup?

Spend the money on the Sine. MSW are good for hand tools and non-electronic devices. Xantra makes a Prosine 1000 or 1800 that is very cool. Be prepared to deal with the inefficency of an invertor. The 1800W (aprox. 15 Amps AC) requires a 250 Amp fuse! You sould consider a H/0 alternator before you get to far into your project. http://www.invertersrus.com/prosine1800.html Page down and you will find the install manual for the unit. Great info.

I have a Custom 5 alternator setup on my tahoe and also have 6  x 1700 amp batteries...4 x Batcaps and a 35 farad Digital Cap.
