My wife and I are moving to Arizona, and evidently it gets hot down there. And it's sunny! And solar panels have dropped to around $1.10/watt! A high powered true sine wave inverter is pretty expensive. It just so happens that I had a (still in development) DIY 3 phase AC controller laying around, so I figured that I should see if I could get a clean single phase AC signal out of it. Well, after changing a few lines of code, and adding an inductor/capacitor filter, it worked! I have an inductor that will do 200amp continuous, with a resistance of only 0.001 Ohms. Now I just need a bank of high ripple current caps. I only need around 4 or 5uF of capacitance, so it should be pretty cheap. Here's the first test!
