50kw Solar daytime only Mining Project

[Longhorn901]

I see that you are having power issues after 2pm, and you have extra battery power running. What happens if the battery is not charged in the morning due to bad weather?

That happens quite a bit, I think the dropouts are issues with the Solis Cloud, the Miner doesn't show any restarts during those times.
Right now I have the inverter running between 50 and 90% battery SOC, in the evening it shuts down at 50% SOC.
I don't have any automation running yet so for bad weather during morning startup the inverter charges the battery to over 50% and starts generating.
If there is more draw than the system can sustain the inverter shuts off again, it keeps this loop up until there's enough solar.
Not ideal for sure.

I think the first script I write will stop the miner let it cool down then shut it down at night then in the morning after it starts for the first time I'll put it into sleep mode until there is sufficient SOC.


Any thoughts?

Usually, the peak of electricity consumption occurs during the daytime. If you find a partner from whom you can buy cheap electricity at night, your mining farm can work much more efficiently.
I see your profit about 675 dollars per month, how much money does your Solar system cost?

So I have enough of the system built to start some test runs, that's what I did yesterday.
I finished setting up and started the first run at 2pm. It ran until 8pm where the inverter shut down at the programed battery low voltage setpoint of 30%.

Will do a full day run today.
This is on a Solis S6 11.4 KW Inverter, 7kw of Solar Panels and 24 KW Nissan Leaf Battery.

Your video was the only thing I found for doing something like this! I didn't see your script on Github anymore though. I saw there's one guy on twitter who is making and selling hardware to do this kinda thing, but that's too expensive and complex a solution for me. I never even invested in batteries. I ended up with a free S19i, which was just sitting around now, thanks to stupid AI data centers jacking electricity to the moon.

I unofficially grid tied my solar install on my own, never doing a Smart Meter and never giving those greedy BLEEPS the satisfaction of giving me a token reward for my generation. Unfortunately for me, I've been giving the neighborhood my excess for free, until now! Since we already have to pay out the a$$ for AI around here, figured I might as well use it to build me a script. I can't program to save my life. I now have a Powershell script tying MultiSIBControl together with Vnish's throttling, which kicks in to mine with the excess solar! It's rough, but it works. Funny enough, I've had to burn just as many hours getting the AI to make a working version, as I've spent cobbling together free scripts for webpages, lol. It even has a buffer for passing clouds. Now the arrows on the meter, for export/draw, dance back and forth, showing it's running right on the edge. Far easier and cheaper for a home miner to just open up a program on Windows and watch it go.

I miss the old analog meter though, these digital replacements suck. They don't credit you properly like the analogs did, and if you want credit, you have to bend over and take it from the power company.
