The solarbit has a small 12v 6amh lithium battery just as a cloud buffer during day ops and acts as the power source over night to keep system alive and ready for tracking next sunrise.

The big static brother is substantial beefier. 8kwh solar input to a 7x2.4kwh lithium battery pack to an 8kw /32amp 230v inverter that powers S21 and immersion cooling hardware ( pump and dry cooler )
