I’m just now getting into the cryptocurrency world Im still learning but is it possible to run mining equipment off a powerwall and also does mining in ultra low temps make a difference in how your miner performs. Im a HVAC/R technician and been researching DYI powerwall and could possibly design self contained renewable energy unit and control the climate in which I mine. Or am I crazy? 
Basically a pinball laptop refrigerator your laptop runs off DC why not make a big laptop if that makes sense that you charge from the sun or turbines from the refrigeration system?
