I have some Antminer D3's and Antminer S9's on order with Bitmain and I'm trying to figure out the power requirements/setup that I'll need. I've been investing for several months and opted to get some units in hand mine in addition to investing. I had an electrician come out and I just need to figure out how much I can run off a 220v circuit.
Right now my setup is like this:
1x - 200 Amp main breaker
1x - 100 Amp sub panel located in my garage
The 200 Amp main is full, the 100 Amp sub is almost full - I think it has 7 open slots currently. Rather than trying to run off it the game plan is to put another 100 Amp sub panel run off my main in the basement where I'll be setting up my miners. I just have the following questions that I'm not 100% on:
1.) I've ordered the APW3++ units for my PSU but it doesn't come with the power cord. Is there a recommended or preferred power cord to use and what type of ends does it
need terminated - I plan to run them off 220V
2.) How many S9, D3 or L3+ units can I get away with running off one 220v circuit?
3.) Is there an estimate of how much heat each unit will put off? When everything arrives it will be winter and my basement generally is about 45 degrees F. I should have a total of 4 units to start but any input on heat expectations would be helpful for Spring/Summer use. My basement is about 1,800 sqft split with the miners on the side under my garage which is about 900 sqft completely open.
My initial thought regarding heat was to get some fans to push from one side of my basement to the other. I do have several windows so once at start getting more I can either install AC units or fans to push heat out. Any info would be helpful to a complete mining noob
