Solterra Premium
All-wheel drive electric adventure. Here's what its onboard charger actually needs from your home's electrical panel.
Home (Level 2) charging facts
Pulled straight from the Solterra Premium's onboard charger rating - not a generic EV number.
- Onboard charger draw
- 6.6 kW
- ~28A at 240V (kW × 1000 ÷ 240)
- Empty-to-full at max Level 2
- 10.8 hrs
- 71.4 kWh battery ÷ 6.6 kW
- Range added per hour
- ~19 mi/hr
- 6.6 kW × 2.9 mi/kWh efficiency
- DC fast charging
- 150 kW max
- Public chargers only - tapers as the battery fills
Typical full-speed install
32A charger on a 40A circuit
Reaches this car's 6.6 kW ceiling. Whether your panel has room for that circuit depends on everything else already on it - that's the actual assessment.
Connector
NACS
NACS (North American Charging Standard, originally Tesla's plug) is now the connector most new EVs are shipping with for both home Level 2 and public DC fast charging.
On the Solterra Premium specifically, that connector carries up to 6.6 kW at home on Level 2 and up to 150 kW on public DC fast hardware.
Charging speed by circuit size
The Subaru Solterra's onboard charger can't use more than 6.6 kW AC no matter how big the circuit - past 32A, a bigger charger buys you nothing on this car.
| Charger setting | This car actually draws | Range added / hour | 8-hr overnight |
|---|---|---|---|
| 16A | 3.8 kW | ~11 mi | ~88 mi |
| 24A | 5.8 kW | ~17 mi | ~136 mi |
| 32A | 6.6 kWcapped by car | ~19 mi | ~152 mi |
| 40A | 6.6 kWcapped by car | ~19 mi | ~152 mi |
| 48A | 6.6 kWcapped by car | ~19 mi | ~152 mi |
Overnight, at full onboard speed
152 mi / 8 hrs
190 mi across a 10-hour window, at 6.6 kW.
Approximate cost to fill from empty
$9.28
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 71.4 kWh - about $0.045/mile.
Subaru Solterra charging questions
How long does it take to charge a 2023–2026 Subaru Solterra Premium on a Level 2 charger?
About 10.8 hours from empty to full at its 6.6 kW onboard-charger ceiling (71.4 kWh battery ÷ 6.6 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Subaru Solterra draw on Level 2?
At its full 6.6 kW rate, the Subaru Solterra draws about 28A at 240V (kW × 1000 ÷ 240 = amps).
Can a Subaru Solterra use a 48-amp charger?
Not to any real benefit. The Subaru Solterra's onboard charger tops out at 6.6 kW (~28A) - a 48A charger doesn't charge it any faster than one already sized to 28A.
How much range does a Subaru Solterra add per hour on a Level 2 charger?
About 19 miles of range per hour at its 6.6 kW ceiling (6.6 kW × 2.9 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Subaru Solterra?
Roughly 152 miles from an 8-hour overnight charge (19 mi/hr × 8 hours), or about 190 miles across a 10-hour window.
What's the DC fast charging ceiling for a Subaru Solterra?
Up to 150 kW on a public DC fast charger - well above its 6.6 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
