A big step to off-grid living, 6kW solar panel with 20 kWh ternary lithium battery storage, all build from scratch, only 1/6 cost compared to Tesla Powerwall. https://i.imgur.com/cZPcuXv.jpg

3 kids father, off-grid living enthusiast, Bitcoin holder, love social engineering to improve human's life.

Connected with 96V - 220v battery inverter and MPTT controller, it finally works after 1 month hard working. This is my first solar-powered coffee, the best one ever. https://i.imgur.com/QRfvCAq.jpg

Built a wooden house for the battery system. Look at the up-right corner, YES, it can also drive a Bitcoin miner, Ant Miner S19! https://i.imgur.com/5qMEUKf.jpg

Then I try whether it can charge Tesla, built a charging pile https://i.imgur.com/MW2aPTX.jpg

Everything goes well, it is not exploded, it can charge at 7 KW at most, meets standards for household charging pile. https://i.imgur.com/0J4VCUZ.jpg

Borrowed a Tesla Y from friend, she asked whether it would be exploded,  I said let’s try it https://i.imgur.com/leERs9V.jpg
