A German Tesla owner has given his used Model 3 battery pack a second life by converting it into a 79 kWh home energy storage system charged by 11 kW of rooftop solar panels. The setup is a real-world example of something the EV industry has talked about for years but rarely shown in practice — that EV batteries don't die when they leave the car, they just move to a less demanding job where they can store solar energy, power a home overnight and keep running for potentially another decade. For context, Tesla's Powerwall 3 offers 13.5 kWh of storage while this repurposed Model 3 pack delivers nearly 6x that capacity from a battery that was supposedly "used up." This is the kind of circular economics that makes EVs fundamentally different from gas cars because when a combustion engine is done it's scrap metal, but a Tesla battery that's degraded past its useful range for driving still has enough capacity to power a house, and as millions of first-generation EV batteries start reaching retirement age this second-life market is going to become a massive industry of its own.
