Here are a few videos of it running on 220 and also it now has a power factor of .99 making it super efficient and even more powerful! 15kva and 15kw are not always the same this one is running at a true 15kw do to the power factor control, it also eliminates the need for the big blue tank capacitor which will make it a very small 15kw unit.
One thing that will make this great for anyone to use is this same machine can be hooked to 120 or 220 and it automatically adjusts itself, at 120 its 5kw and at 220 its 15kw, if we had access to 3phase we could run it at 30kw.
This unit is nearly done, the boards are about to be made so that the messy looking breadboard setup will be done away with, then it will be tested heavily to work out any final kinks and we will try to build a few more.
Check the description in the videos to see when the machine is turned on.
