I watched your video! Love to see what you've done. Are you turning the miners on and off manually? 

The low voltage is definitely a challenge. My furthest wire run is 45ft and I had to spend quite a bit on wire that could handle the runs. Thankfully it's a one time cost. I'm still gathering data to see what my efficiency numbers will be, but Dirty says he's achieved as low as 16w/Th on a j pro. Those power supplies do eat up some watts. 

I don't think that direct dc is the best solution for all applications, but it is pretty cool to see the miner tuning it's power draw to what the panels are producing in real time.

Mining Bitcoin with Off-grid Solar: Experiences So Far

I am very curious to see the components that make up your setup.  I run 6 s19 miners off of solar but I am using just the standard 240v power supplies. I have not got into the 12v DC mods yet.  On the solar side it seems like it would be challenging with loew voltages. I use all 48v battery setups and high voltage solar runs to keep wire size and voltage drops down.  Here is a a little video I made if anyone in interested.  Thanks for the post.
