What EV Charger Do You Need for a 2026 Subaru Solterra 20?
Wiring a home charging station for the Subaru Solterra 20 requires pulling a dedicated 60 amp circuit and hardwiring the unit directly to your electrical panel. You need a 48 amp Level 2 charger to match the car's maximum onboard charging capacity. This setup delivers 38 miles of range per hour and fills the 80.4 kWh battery in 7.3 hours.
The numbers
| Maximum AC charging rate | 11.0 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 7.3 hours |
| Range added per hour (Level 2) | about 38 miles |
| Full charge on a 120 V outlet | about 56 hours |
| Range added per hour (120 V) | about 5.0 miles |
| EPA rated range | 278 miles |
| Energy for a full charge | about 80.4 kWh at the wall |
Why 48 amps and not more
The car draws up to 48 amps on AC power, so a 48 amp EVSE hits the peak rate without wasting money on heavier gear. If you hook up a smaller charger, the vehicle draws less current and charge times stretch out. Buying a 50 amp hardwired unit like the ChargePoint Home Flex lets you dial the output down if your panel runs tight on capacity. Units pushing past 48 amps will not speed up your charging session because the onboard charger limits intake to 48 amps anyway.
What the install involves
A 48 amp charger cannot plug into a household receptacle because no standard outlet handles that continuous load safely. You must hardwire the unit directly to the building supply. Have a licensed electrician check your breaker box for spare capacity before buying hardware. They will need to land a 60 amp breaker in the panel and run heavy gauge copper wire out to the garage wall.

Common questions
- What plug does the car use?
- The vehicle uses a J1772 connector. Many units ship with a NACS port and include an adapter, so check your specific port before purchasing equipment.
- How long does a full charge take?
- Plugging into a Level 2 charger at the maximum 48 amp rate takes 7.3 hours. The EPA rated test time sits at 8.0 hours because standard testing cycles do not always run at the car's peak AC rate.
- Can I use a standard wall outlet?
- Level 1 charging from a standard household outlet takes 56 hours for a full tank and adds 5.0 miles of range per hour. That method only delivers trickle power, making a hardwired Level 2 setup necessary for daily driving.
- What about Tesla chargers?
- You can use Tesla Destination Chargers and Wall Connectors if you buy a Lectron Tesla to J1772 charging adapter rated for 80 amps. The car itself relies on the J1772 standard.
