Could you in theory run an antminer S5 direct from a 12 volt battery bank if you had a voltage regulator in between to ensure no voltage spikes? What problems do you forsee? Any workarounds on those problems?

A little about why.

I like to tinker, i knew since last week when i got into it that bitcoin was never going to be a money maker or an investment for me. But that does not stop me from blowing a little money on trying to tinker with things involving bitcoin.

I have recently ordered ONE OF THESE 800 WATTERS from ebay. I picked up a 12V 65 Amp 750 Watt charge controller, a dozen batteries, all the cables. some PCIE cables, and just incase i cant figure a way to direct wire without the PSU in the middle, a 1,000 watt inverter and Gold PSU.

90% of the year i have a steady 6-10 MPH wind 12-16 hours a day in my back yard. I intend to set up a "mine when the wind blows" little rig that converts wind into bitcoin, BEFORE ALL OF YOU START IN, i am well aware that i will never in my lifetime recover the cost of the investment i made alone by running 1 miner when the wind blows. This is simply a tinker fart around project. Last year i made a wind powered desktop PC that seeds movies to the P2P network when the wind blows and it runs smooth 6-12 hours a day without problems. I also make no money from that either.

All my bitcoins I ever mined were solar powered.... the problem I see with your setup is you are converting DC to AC back to DC.... each time this is done , there is a loss.... to be most efficient ...... The only way is a grid-tie setup....

DEEP CYCLE Batterys need to be charges at 14 to 15 VOLTS... ALSO you don't want to discharge your battery's when there is long periods of no wind.....

WIND POWER is tricky.... the more wind the more volts.. and sometimes that needs to be dumped into a resister if your battery's are charged

I HAVE A SOLAR GENERATOR on my shed.... I have 5 , 120 amp hour batterys..... you said you have a dozen batterys

I'm afraid you don't have enough amps to keep your battery's charged and your system/ batterys will die rather quickly

Please give more spacifics on your equipment... so I cam understand your setup and plan...

Also you need to do the math...your usage and power production and your total amp hour battery capacity . I DONT T THINK IT WILL ADD UP...

PS. My coins were mined on a 7.5Kw grid tie setup on my house...your best bet is to grid-tie your setup and the amount of power you generate ..convert that into a dollar amount and just buy bitcoins....
