Hey, here is a little schematic of my inverter shutdown control. Let me know what you guys think. I'm pretty sure I got everything right, but if you see a problem with it, let me know quick! Thanks.
It's a pretty big picture, but the file size is small. Less than 50k.
Here's a smaller version.

Keep in mind these prices are STEEP! I bought mine at our local electonics supply store for $17.
Here's one for $20. http://www.weisd.com/store2/NATQ4F-00010-326.html
