Thank you for sharing this goodness. Will be very helpful for us as we expand our solar next year on the farm and hook up more miners for heat

my electrotechnik mind is not happy with this arrangement there must surely be a voltage regulator in this picture somewhere PSU is putting out some amount of power, meaning volts and amps of current making a failover for power systems usually requires an accumulator somewhere in the picture, ie, transformer and capacitors adapting to the flow usually takes logic and gates i'm not sure you have got this unless you have some kind of large capacitor buffer in the circuit

i'm just wondering how this works if the voltage is going into the PSU, which is a transformer and capacitor thing, where do you tap in your extra power... seems like it must have to be right on the capacitors because only that would not interfere with the voltage if the solar array is loading the capacitors then they would not draw so much from the mains to charge and discharge into the bridge rectifier that produces the 12V current for the miner... that's the only place you could add extra current without disrupting it does it actually work stable? as in, it doesn't pull power from the mains AC with the DC current from the array?

Look forward to seeing it

The voltage regulator is the charge controller, when hooking it up to the PSU, it sees it as a 12v battery.

S9 hashing on direct DC solar and AC PSU hybrid system Here I have an S9 powdered both by the 12v DC output of a solar charge mppt controller and the output of an apw3++ plugged into an inverter. The output of the solar charge controller is wired directly to DC output lugs of the PSU. As the clouds roll by the output of the solar power decreases and the PSU delivers more power from the inverter. This same technique can be used by plugging the PSU into a grid powered outlet instead of the inverter. It's basically a way to subsidize the power consumption of a miner with solar power directly. It's pretty cool to watch. #bitcoin #bitcoinmining #plebminer #homemining #offgridmining #solarmining #offgrid#solarpower

So as long as your batteries are sufficient voltage I guess?

Yes, if the batteries die and the sun is shining then I might be in trouble.

probably just need a voltage triggered off switch that just turns all that side of the circuit off once it drops below the voltage the devices need

A single board can handle 100 amps. Just size the controllers appropriately

Dude. Amazing. Please do provide more info on this when you can.

Definitely need domething similiar. Is your solar sysytem12v24v, 48v ? What size inverter? Saludos

VERY TASTY! Reposting cause I can't figure out bookmarks. IQ 80. I recently to learned that you can wire the DC output of a solar charge controller directly to the power lugs of a Bitcoin miner PSU. The power from the solar panels goes directly to the hash boards and if there isn't enough power, the PSU makes up the difference with ac power from the grid. It turned the PSU into off grid solar grid tie hybrid power source. All solar power is totally utilized, no loss. It's magical to watch the power draw from the PSU ebb and flow with the power output of the solar charge controller. This is technique is going to change the game here at the homestead as it will allow me to continue to expand the solar power production without having to get a larger inverter to fully utilize it. I can tie the additional solar power directly to the miners, skipping the batteries and inverter all together. Looking forward to showing this technique in action.

are you 100% off grid? I’m wanting to tinker with running miners off solar. Working on my first s19jpro space heater build.
