But for that we need the PV to be configured in 12V right?

Take the below case and how you will add a Solar Panel & Controller in this already existing setup with or without relay?

Battery 12V/100AH x 2 in Series to get 24V 100AH
Inverter 24V 1500VA
ASIC Device 12V/400W

Since the inverter need 24V the battery need to be setup in series.
So the PV modules and Charge controllers need to be setup in 24V configuration.
Then how we can obtain 12V to the ASIC? Assume the above existing setup cannot be changed except solar panels and Charge Controller
I'm not at all familiar with PV and Charge Controller so, I assume the CC never converts 24V to 12V.

Take a look at an image. http://s29.postimg.org/qri7f8ht3/Solar.png
I'm not sure the Replay connect is like that. Hope an experienced one can redesign the wiring and post an image.

Well hello there!

Liking this thread. It never ceases to amaze me just how many different types of peoples from so many diverse backgrounds and strengths can be brought together via this thing we call bitcoin! Would love to one day have access to some serious natural energy to run a huge farm and support the network

Here the issue is "when the battery will drain off and when that turns off":
We need a stopping point to switch to psu power before the battery drains very low and the devices get low power and malfunction, right?
Further that's bad to the battery too. How we will achieve that?

I think we will require some kind of a circuit to sense that low voltage or power point(like inverters/ups shut-off) and cut-off the supply from solar.
Then it the repay will have no power flow on one channel and it switches to the other one, to psu output.
Then in the morning when Solar provides enough power the relay switches off psu and lie in solar.
And the battery will be just used during night if PSU input Supply fails.

Regarding soldering battery wires to PCI-E connectors are also a problem. What you think about that?

The charge controller between the battery and solar panel will stop the battery when it goes below 11.5 and the relay will switch to the computer power supply.

Check the antminers for their input requirements. If they take 12VDC +/- 2 VDC, then scrap the DC>AC>DC arrangement and hook them straight up to a battery. I do this with my Jally.

Solar panel (200W) + wind turbine (200W) > hybrid combiner/controller > batt (nominal 12VDC) > Jally + R-box

Input the same as above > batt (nominal 12VDC) > UPS (400W) > Laptop (signals startup & shut down based on battery condition)

Yes Cranky4u. That's what I was thinking too, but adding a 12v output from a computer power supply. You would connect the computer power and the power from the battery charge controller up to the dpdt relay and it would switch between the pc power supply and solar power depending on if the solar is available or not.

Thanks to all.
1. What kind of a Replay you advice here?
2. If the power from solar is low during low Sun will this replay switches to PSU?
3. Also what kind of a cable you are using to connect your devices to battery. Normally inverters use cables of very higher guage to connect to battery, so do I need to use such a kind of cable?
It will be more better if you can add an image of what you have done or others done such things.

1. I assume by replay you mean relay, and you would need a 12v dpdt relay, with whatever amperage you need, which is wattage/voltage. So for a antminer you would need something like http://www.ebay.com/itm/2pcs-JQX-30F-2Z-DC-12V-Coil-30A-250V-AC-Power-Relay-8-Pin-DPDT-/300715926685?pt=LH_DefaultDomain_0&hash=item460410e49d
2. If the power is low, first the battery will drain off, and when that turns off, then the relay will switch to the PSU's 12v power supply.
3. Definitely use a higher gauge wire between battery and the charge controller. 12v has high amperage. You can solder connectors up to the wire and screw into the battery terminals.

Will definitely make a guide if I ever get time to finish this project Grin

Depending on where you live, I would get probably 800 watts of solar panels, the rated wattage are only on the full sun. PVC pipe Wind turbine might be better because its 24/7? Definitely interested if anyone tries this idea Grin

Ah!!! How much is your 800Watts panel cost in $?

If you make your own panels...probably still a good $400 dollars. After the use on the 12v antminers, you could definitely use the 12v supply onto 750ti's or even a 280x. This could have a good roi over a few years. If you only run on solar, you wouldn't have to install more 12v relays into your breaker box. The 12v relay and wiring is a good $100 or $250 if you get it installed.

and then hook up the panels to the input, batteries to smooth the voltage, and the miners to the output. This would be much more efficient than making DC to AC and then back to DC and would save 30% ON EFFICIENCY and be much cheaper. Then, during the night you could hook the output of the DC charger to something like a 12v dpdt relay, and hook up the computer PSU 12v to the relay and switch between solar and wall power when there isn't any solar power.

That idea is good but practically need to check the implication problems.
Do you know how the voltage will be in b/w terminals when solar is connected to battery? I think it will be varying and the input to Ants will be an issue.
What you think of it?

Also I was actually looking for how many panels and their W ratings.

I believe the charge controller will let it go up to 12.5 and down to 11.5 volts and then shut off. I have ants, and don't quote me on this, but I think the voltage regulators will be okay on the antminers. The antminer chips are running on 1.5 volts I think. You could also use the charge controller in 24v mode and then step it down to 12v with a step down converter and it'll be a more steady 12v.

I will experiment it when my Antminer S1 is near EOL. Or need to get an old miner for testing. Requesting if anyone having a solar miner to do the test if you are a DIY person.

wahhhhh
i want to do this experiment too
in my country (indonesia), electricity always down once a day with duration of 2-4hours, so i had to buy inverter 1500w with auto charge + 2x100ah only to backup my S2 around 2hours, often miss another 2hours...
but nvm, got no cash T_T

Waiting for your updates.

As per my calculations running it during non solar time in battery require a large battery bank of around 15+. It should not be viable to use solar during night. So limiting it to day time. Now no of panel and its specifications matter.

200/100W * 12V or 200/100W * 24W

better you get solar inverter then a regular inverter (su-kam solar inverter with inbuilt converter works on both solar panels and electricity)

My inverter is solar compatible. Not sure whether it is inbuilt with controller.
