Hey Longhorn,

Thanks for the invite!

You are doing pretty much what I was asking about.

I would love to hear the particulars on how you are controlling the miner "throttle".

Regarding batteries, I just ordered some Lifepo4 for another project but I may rob some of them to try out on this project. I have enough coming to assemble a 12V 1120A/H bank.

The ability to gauge solar production and battery state and throttling the miners based on available power.

I have some time to put it together. Being at a Northern lattitude, solar sucks in the Winter. Even worse, we heat with electricity. I am going to run my miners from grid power, in the basement, and heat my house with them until late Spring. Then I will relocate into the garage and hook up the solar.

Hi Steve,

My vision for this system was a self contained pod of the solar and miner in one unit that you could set up somewhere with the only outside connection needed being the internet.

I set the solar up a couple years ago to power a bunch of CPU miners on VRM. That turned out working pretty good but not worth doing.
So I'm re-purposing the solar for this idea.

So as far as the miner control at this point it's simply an arduino with one of its ADC inputs reading the battery voltage, when the voltage drops below a setpoint the Arduino opens up a relay shutting down the miner.
Then when the voltage rises above another setpoint it closes the relay which starts up the miner again.
Here's the program on github, not the most current but close...

I'm also doing some simple data logging and graphing to a server which was controlling the number of CPU cores mining in the old CPU miners.
That's how the system maximized mining, more sun more cpu cores running.
Maybe do something similar with the L3 by controlling the frequency but I might just switch in and out individual cards.

I know what you mean about winter and the sun, I moved from the northeast to South TX to get away from the suck part of winter Wink
