Well done on your set up, I tried to do the maths on it and for me it didn’t work out spending 150-200k to go partially off grid! A lot of these solar companies are jacking up their mark ups too which extends your ROI past the battery replacement rates

For my personal set up Until the power 10xs in cost or solar comes down a bunch would it make sense for me even with bitcoin miners consuming them unused energy

For now still rolling with the punches, and wish you many happy days without having to deal with Eskom
