Installation Notes for Tesla Model S
- →
Model S has the same 11.5 kW onboard charger as other current Tesla models — a 50A circuit (48A continuous) is ideal and delivers the maximum AC charging speed.
- →
The 100 kWh battery means a full charge from near-empty takes 9–10 hours at 11.5 kW. Most owners charge nightly and rarely go below 20%.
- →
Model S owners in Atherton, Hillsborough, and Palo Alto often have updated 200A panels — straightforward installs. Older homes in Belmont or San Carlos may need DPM or panel assessment.
- →
Tesla Wall Connector is the preferred choice for Model S due to native NACS integration and the clean, minimal aesthetic that suits luxury homes.
- →
If you have a Model S Plaid or long-range that you use for road trips, a 50A circuit ensures you can maximize overnight top-ups after longer drives.
