I think Jack Rickard has the plug now for $1300. That's still absolutely stupid.
My goodness, They really should have just had some sort of anderson connected with heatshrink around the ends for the high voltage, and maybe a different connector for the low power part, and software can deal with making sure both are plugged in at the same time. $3000 for a connector retail is like they are trying to make the whole thing fail on purpose.

I found a bug in the split phase code. I hooked up ONLY the solar panels straight to the inverter, and everything worked great. The higher the load, the 500v just sags down until the power is sufficient (running the mill sagged the solar array down to 475v), and then the inverter just takes the 475v and puts out 120/240. As long as the solar is above 340v, it can do 120v/240v out. Now, here's the bug!

I was not actively forcing the 2 120v to be balanced. So, now I need to monitor the AC output voltages, and then change the duty of the middle channel so that it stays 120 and 120. The mill caused it to be 110 130. So, all you have to do is, say HEY! ONE IS 130, change the 50% duty to 45% or whatever so that the 110 gets pushed up and the 130 gets pushed down.

The panels had no problem with the startup surge on the mill, which can go to 200amp. After work I'm going to get a 2 1/8inch drill hole maker at Ace (as well as some popcorn for my 5 year old from them! haha) so I can add that 4 wire 240v dryer plug out at my shop, so I can charge the car directly from the solar. I'm really happy with how it turned out. Now I don't have to have any batteries out there.
