actually houses in my area are so big, with hot tubs electric cars requiring 50kw fast chargers etc its not hard to find a house sized with 400amps, throw in a detached garage you can easily get permit for another 300 watt for a garage shop.
Its false that they make you pay for the transformer all they need is a city permit and they put up the pole if needed.
power is not an issues. the issue is residential rates are bad for mining. Im my shop i have businesses rates , slowly moving my rigs there. I pay .04 plus deman rate in the garage. In my residence i pay 12 to 15. cents in summer no less than .11 in winter
Well, just because the main breaker says 400A doesn't mean you can actually draw 400A for more than a few seconds. Firstly, the NEC limits maximum continuous use of any circuit to 80% of the wiring or breaker rating, whatever is less (usually the breaker). Secondly, the distribution transformer (usually affectionately referred to as a "pig" if mounted on a utility pole) will likely be rated for 10kVA to 50kVA if pole-mounted, and 50kVA to 200kVA if pad-mounted, and each transformer will likely serve 1 - 6 houses so you really don't have nearly as much power available as you might think.
Our esteemed OP can probably provide a bit more detail on this seeing as he has had major electrical service work done, along with solar tie-ins, etc.
well so many variables here.
and the internet makes it hard to write precisely .
As it gets boring to read a long reply.
marvell is saying in his area he can get 400 + 300 = 700 amps which for a home owner is a lot of power.
700 x .8 = 560 at 240 volts = 134.4 24/7/365 draw thats a lot for a homeowner.
you can run 100 avalon 841's
or 100 6x1080ti rigs
and that is a lot for a home.
Marvell is also saying most home owners pay quite a bit more then 4 cents a kwatt.
my garage cost is 18 cents in the summer and 10 cents in the winter.
my home was never setup to run over 12 kwatts in the winter
and runs under 3 watts in the summer
my home is a 150 amp 220 single phase setup.
The solar array has 400 amps 240 volts
It runs buy solars house his office and the mining gear.
and it never can go past 75 kwatts for charging back as the power company restricted sell back to 75 kwatts per daylight hour
the array on a perfect sunny day in July could charge back 105 kwatts so power is wasted. this is due to transformer limits .
Buysolar paid an extra 10000 for the transformer and some power company wire upgrades.
Even though buysolar could make his field more powerful the power company won't handle it.
Lets leave it at this:
tight margins favor:
cheap plentiful power.So a 2 megawatt solar flield can do 400kwatts for free that would be 300 s9is
if you have an empty 2 megawatt field ready to go on ling you could buy 350 s9i's
and make money for quite a while. so anyone with cheap power in abundance is buying those s9is
buy extra for spare parts.
my example above in nj would be 2million to setup and the gear would be about 220,000 more
so 2,220,000 run 300 s9s keep the rest as parts.
in 3 years it is still earning 10k a month
you got back 1,000,000 of the 2,220,000 million
and about 400,000 in tax credits you owe about 820,000 on a 2,220,000 investment
and remember 2,000,000 of that is solar which has a 25 year life span
this is killing the garage miner cause people with money see this a way to pay for solar.
