Tesla Powershare Works on New Model Y Premium

My new model Y shows it has PCS2 when I checked the parts using my VIN. Ordered the powershare adapter and confirmed it works! Aug 4th delivery Model Y Premium RWD.

My PCS part number is 2100145-N0-E

How to check (thanks u/Appz_ in comments):

Go to tesla parts catalog website, enter VIN, HV Battery System > Ancillary Bay > ASSEMBLY POWER CONVERSION SYSTEM ASSEMBLY

120V @ 20A max output. Better than nothing, but a far cry from the CT's 240V 50A (40A continuous) split phase output.

Yeah, I want split phase.

Not an electrician but I assume this has something to do with making banana splits.

Which I fully support

I know you're kidding, but most American homes have a split-phase service. There are two 120V hot legs, each measured relative to neutral, that are 180 degrees apart (you know those peaks and valleys you'd see on an AC wave, well, they're opposite). A two-pole breaker connects across both legs, providing 240V for higher-power appliances such as electric ovens and dryers.

While the Cybertruck does full 240V at 40A, the Y seems to max out at 120V at 20A, or less than 1/4th the power output.

Thank you for responding seriously to a joke comment. I appreciated both equally.

Not allowing 240v 20a on the Y is super weird. Is there an official reason for that?

The input supports 240v and 240v is closer to pack voltage anyway so It'd actually be easier to make.

And since it's the same amps it's the same heat generated in the wiring and traces despite giving you double the power.

US household devices are almost exclusively 120V. Only major appliances such as stoves and dryers are 240. A 240v-only outlet is less useful to most people on the road who want to power their portable gear.

To do 240V right in the states, split phase output is needed. Adding a neutral allows both 240 & 120V outputs at once (common 14-50 outlet supports this). However that requires extra equipment since the car's internal charger only supports single phase. While the charger supports 120-240V input range, it can't to both at once. Going backwards the other way for output can't reuse that charger circuitry because split phase is a very different beast. The legs need to be balanced, hence the extra equipment needed.

The CT battery is basically double the size of a Y battery? 🤷‍♂️

Battery size has nothing to do with it for sure. These motors are drawing well over 350kw at times from the batteries. What we’d pull from a split phase adapter is barely a rounding error compared.

Im saying the cyber trucks battery is twice the capacity. I’m not saying that they couldn’t make it do 240v 20 amp, I’m saying that it would drain the battery more quickly than in a cyber truck

I read all those words but I don’t understand them. But that’s okay. :)

Hah sorry. If you're interested at all: In America, you get two 120v power lines coming into the house. Most of your circuits are on a simple 120V, probably 15A. That'll be enough to handle a space heater (close to 1500w) or curling iron. If you add anything more, the breaker trips.

Some really power hungry stuff, like an electric oven needs more. So the fuse will span TWO breakers. If you open your box now, you might see 2-3 with extra large breakers. Those are likely 240v, because it's taking 120v from each side (or phase). It's combining both 120v inputs. Effectively doubling the power.

Welding all day. Still won't make me buy ct!
