Advice on Home Charging Setup for Polestar 3

[Ovelia_Atkascha]

I’ve got a Polestar 3 on order (USA) and am trying to figure out the best way to set up home charging. According to the Polestar site, they recommend an 11 kW AC Wallbox using 3-phase, 16-amp power for optimal charging, and they specifically suggest the ChargePoint Home Flex. I thought I’d be all set, but things got confusing after talking to my electrician.

He basically told me that 3-phase power is for industrial setups and not something he’s ever installed in a home. Instead, he recommended running a 50-amp circuit from my breaker to the garage with a 240V outlet, which he says will work great with the ChargePoint Home Flex set to 48 amps. This would apparently provide a pretty solid charge rate by U.S. standards (most home setups seem to max out at 40 amps).

With the 111 kWh battery in the Polestar 3, I want to make sure I can charge it overnight without any issues. Does anyone have experience with the recommended 11 kW setup or know if 3-phase is even necessary? And is my electrician right that a 30-50-amp circuit with a 240V outlet is actually more typical for home setups?

You can charge at 11kW, so it'll take about 10 hours to fully charge. But you probably only need to charge overnight, right? So it should be fine.

Your electrician's advice sounds good! A 50-amp circuit with a 240V outlet should work great for charging.

I'd suggest going for a high-quality 14-50 outlet, like Bryant or Hubbell. Also check with your power company or see if your county offers any incentives. They might cover some of the cost of installing a home charger if you buy a specific brand of EV.
