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.

quoting nevent1q…5cq7I 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.
