To do what? Mine bitcoin? Not possible with solar only.
Discussion
That is why I would buy a bitcoin miner. Or maybe to heat the battery box in the winter. Why is it not possible to do this without grid-tie power? Without boring you with system specs, my numbers say I can run a small miner.
You can, if you use Bitaxe or Nerdaxe. But those are just toys to learn about mining. A proper miner needs sustained power of 3 to 4kW/h. You need a pretty big solar farm for that and what are you going to do at night?
I looked at the s17 & s19 miners - they are power-hungry. I am designing the solar to slower my garage and outdoors things(lights, refrigerator, IP cams, etc.). A small miner is just frosting on a cake. If it makes back what I spend on it, good! Otherwise I wasted $100 on a lottery ticket. (It may be the single time I gambleβ¦)
How much power can you provide?
Not possible to buy a s19 under $500 nowadays.
Iβll be producing around 1.5KwH/day (max). Small potatoes. Enough for my garage refrigerator, lights, IP cams & a few lights.
Refrigerator is on a timer - kept on long enough to keep things cool, but not all the time.
Iβll build an 8βx12β shelter (roof will face south only - no ridge in the center like house or barn haveβ¦) over my picnic table and plan to mount panels on it. I havenβt done numbers yet to know what Iβll have space to put on it. I have things for a 12v system, and plan to start with that for a few years then migrate to 48v.
S19 needs 3kW an hour.
Not a day, an hour. π
