I'm running 10kW of mining gear and ~5kW of grid tied solar. Solar supplies about 10-15% of total daily consumption, in Florida. Realistically, I would need more than a 50-60kW solar array, at minimum, to cover 240kWh daily use. So you either need a shit ton of expensive battery or are going to be grid tied, back feeding to power company most of your generated power, only to buy it back later at a higher price. So you need at least ~6X in solar what your intended load will be if located in a 4 sun/hr geo zone.

This is good info thanks. The only issue is selling power back is not an option at all. So I'm left with battery and simply having downtime for powerless hours.

The battery only serves to store what the miner doesn't use during that day off the solar. It could run maybe a few hours after light and then I'll need to switch over to wall power. A arduino unit controlling a physical relay switch could handle a task like this.

I'm unable to sell back also. As long as your load exceeds your maximum production potential, at all times, you can use grid tie and never back feed. That is how I can run solar gear and grid tied inverters with no contracts, permits, inspections, and barely any install costs; by doing it myself super cheap. Everything has to be synced so that power is coming from same phase in breaker box as solar inverters are feeding into, now power company never sees the solar production, just the varying constant load from the miners.
