What EV Charger Do You Need for a 2023 Subaru Solterra?
You need a 32 amp Level 2 charging setup for this vehicle. The onboard charger caps power intake at 6.6 kilowatts. Buying a larger charging unit will not speed up your daily turnaround.

| Energy for a full charge | about 70.5 kWh at the wall |
Why 32 amps and not more
Your battery capacity sits at 70.5 kilowatt-hours. Pumping more than 32 amps into the car is useless because the internal hardware rejects higher currents. A 40 amp breaker is required to supply the correct power draw safely. The EPA test logs a full charge at 11.0 hours, while the raw maximum rate hits full in 10.7 hours. You gain 21 miles of range for every hour plugged into Level 2 equipment.
What the install involves
A licensed electrician needs to pull wire for a 40 amp circuit and land it on the correct breaker. Check your main panel for spare capacity before buying parts. You can use a NEMA 14-50 outlet or hardwire the unit directly to the wall. Hardwiring removes the need for a GFCI breaker in many jurisdictions, saving you money on hardware costs.
