Subaru Solterra EV charger: which one suits you best?
The Subaru Solterra charges at home on a single phase, up to 6.6 kW. A stronger single-phase charger changes nothing because the car sets the ceiling. A three-phase model can even slow it down, and the next section explains why. For this electric SUV, a 7.4 kW single-phase charger is the logical choice. Other Subaru models charge at different speeds, so compare them in our overview of EV chargers for Subaru models.
For the Subaru Solterra, we recommend a charger from our range of 7.4 kW EV chargers.

Which EV charger suits the Subaru Solterra?
At home, you charge with alternating current (AC) over one or more phases. A phase is one of the live conductors in your electrical connection. The Solterra uses one phase regardless of what you connect it to and draws up to 6.6 kW. A 7.4 kW charger therefore makes full use of the car's AC charging capability.
A three-phase 11 kW EV charger supplies 16 A per phase, and the Solterra uses only one of the three. It then charges at about 3.7 kW and takes roughly twice as long. Already have a three-phase connection at home? Then a 22 kW EV charger can keep the full 6.6 kW charging power because it supplies up to 32 A per phase.
One check before you order: this page covers the Solterra with the 6.6 kW single-phase onboard charger. The later 73 kWh version accepts considerably more AC charging power, so take a look at our Subaru Solterra 73 kWh page if that is your car.
Two features are worth considering at this power level. A charger with an app lets you set charging times and monitor a session from your phone. If you have solar panels, a solar EV charger can use your own surplus solar energy to charge the car.
A MID-certified kWh meter is a certified meter built into the charger. It records exactly how much electricity is used for charging at home, separately from the rest of your household consumption. This makes it easier to see how much electricity the car actually uses. In our range, chargers with a MID meter start at 11 kW.
Want this feature? Then look at our chargers with a MID meter. A 22 kW model can also keep this car at its full AC charging speed.
The Solterra has a Type 2 connection, like our EV chargers. A separate Type 2 charging cable is needed if your home charger has a socket instead of a fixed cable, or when charging at public charge points without a tethered cable. If this is your first charger, our home EV chargers provide a useful starting point.
On the motorway, the Solterra uses a CCS connection for direct current (DC) fast charging. There it can accept up to 147 kW.
How long does the Subaru Solterra take to charge?
Around 64 kWh of usable battery capacity divided by 6.6 kW gives roughly 10 hours of theoretical charging time. Because some energy is lost during charging, a full charge takes about 11.5 hours in practice. Plug the Solterra in overnight and it can be full again by the morning.
Most days, the battery will not be completely empty, so a partial overnight charge is usually enough. Running a heat pump or induction hob at the same time? Then consider a charger with dynamic load balancing. It automatically reduces charging power when necessary to help prevent overloading your main electrical connection, and this feature is available on both single-phase and three-phase models.
Charging the Subaru Solterra at home: what to watch for
The Solterra is closely related to the Toyota bZ4X. It does not support Plug & Charge via ISO 15118. This standard allows a car to authenticate itself automatically at a compatible charging station. Instead, you start a charging session with a charge card or through your charger's app.
We recommend having the connection installed by a qualified electrician. This is safer and can also be important for your insurance. Wallbox Discounter arranges installation in the Netherlands, Flemish Belgium and Germany. We ship worldwide, but outside those three countries you arrange the installation yourself.

Frequently asked questions
Does the Subaru Solterra need a three-phase EV charger?
No, and an 11 kW model can even reduce its charging speed. The Solterra charges at up to 6.6 kW on one phase. An 11 kW charger supplies 16 A per phase, so this car uses one phase and charges at about 3.7 kW. A single-phase 7.4 kW charger allows the car to use its full AC charging power, and so does a suitable 22 kW model that can supply up to 32 A per phase.
Do I need an EV charger with a MID meter for the Subaru Solterra?
Not necessarily. A MID meter records home charging separately from the rest of your household consumption, which is useful if you need to reimburse or account for charging costs. It does not make the car charge any faster. In our range, you will find this feature on 11 kW and 22 kW models.
How long does a full charge take for the Subaru Solterra?
About 11.5 hours on a 7.4 kW charger, because the car itself charges at a maximum of 6.6 kW. DC fast charging is a different story: at a CCS fast charger, the Solterra can accept up to 147 kW.
