Cool but looks like a pretty small set-up, I wonder if he actually generates enough power to keep them running at night.
On a really good day in the UK that 500W Solar setup will generate about 4KWh of power. The S3 consumes 360W, so that's about 11 Hours running, so no overnight. On a bad Day they will generate no power at all. On average he will be able to run the miner for about 3 Hours a Day.
As I said above the whole setup, Number of panels, Inverter size, Battery Bank size is all out of proportion for what it can achieve.
