All the miners run on 12v - why not set up a bank of batteries and 14v solar to top charge all the batteries and just have a brownout circuit cut the connection if it dropped below 12v. I am an old custom car guy and as I wander my garage I have a ton of GIANT 12V power supplies from running batteries to charge large scaled stereo displays. One we built had 4 yellow top optimas and a Kinetic battery optimizer. Currently we are losing a lot of efficiency going from dc-panels to ac inverter and back to dc. I know it's not the norm, but I guess I'm not normal. Yes I am aware that it would take a healthy array of batteries. and solar panels.
Tangent # 2 CHademo plug on nissan leaf. They have already developed leaf to home - essentially a bi directional charger/inverter. It's too bad the nissan leaf doesn't have a 100wk battery in it. With it's little itty bitty 23KW battery it's not worth hot lapping to charge the car in my opinion. Even tho there are a lot of FREE chargers in Las vegas. I used to have a tesla, but it was prior to the chademo adapter. The adapter is $500 approx for the Tesla and the leaf to home 6kw inverter 20kw charger I can get for about 4k. I cant be the only one that has thought about this. 90-100Kw super charged and used at home becomes worth it quickly. However, I can't imagine that Tesla has not figured out that this is an option....
let me know your thoughts...
