PowerShare + 240v Outlet

[TCT2024]

Hi there!

First time poster here as a new Cyberbeast owner (converted from F-150 Lightning).

Would love to ask 2 questions for folks who already have PowerShare installed:

• Can anyone with PowerShare installed confirm if you can use both PowerShare and the 240v bed outlet at the same time? e.g. if my power goes out, can I use PowerShare to power my home while also plugging an EV charger into the 240v outlet of the CT at the same time?
  
  
• Does anyone have any tricks to actually getting the promo code to buy equipment on the Tesla store? I was able to get an installation quote in less than an hour through QMerit but have been waiting for 2 months since purchase for any news from Tesla :/ I was approved as eligible back in January.

Thank you!!!

Nope.

Ok wow I could’ve sworn I looked at that whole FAQ but must have somehow missed it. Funny story - calling Tesla support they told me the exact opposite.

One thing folks might find useful to know is it looks like the CT does *NOT* have a neutral-bonded ground GFCI 240v outlet. This is great news for anyone who wants to directly wire a standard generator inlet directly to a breaker in their panel, use a cheap interlock for safety, and just plug your house into the CT with a common 50 amp cable. That was the opposite on the F-150 Lightning which required some creative thinking to make it work without tripping a ground fault.

At this point I’m 99% sure I won’t actually install PowerShare. The Tesla gateway basically seems to be a fancy transfer panel where you have to pick a subset of your circuits to have backup power. PLUS they won’t let you wire big breakers like AC units or ovens. The cheap option lets me use whatever circuits I want. Yes I need to be careful not to overload it but at least for my house running pretty much everything I needed (lights, WiFi, fridges, TVs, computers, etc) including a full size AC unit in 95 degree weather was only ~4KW…less than half of the 240v outlet’s continuous 9.6KW capacity.

Only real downside of the generator inlet direct to panel approach is you do have to manually plug in a cable if your power goes out and flip breakers. Also no fancy app tracking/control. For me, not a huge deal.

My power went out the other day and this worked no problem!

If my $2.5k voucher ever shows up, looks like the kids are getting the mini CT! No idea what else I really need from the Tesla store.

Our house has 400A service, but can mostly run on a 5.5kW genset with manual load shedding, so I feel your pain.

A double electric oven on it's own can pull more than Powershare can supply and AC units can exceed the LRA rating of 110A, so it's very case by case (including homeowner's expectations).

I wired my whole house to Powershare and will flip breakers before I power up. I did not choose circuits to power because I wanted to control what had power andnwhat didn't.

You loose a about 2k watts going the bed to plug route.

This is really only a loss if you’re trying to run a ton all at the same time, though. If you’re using this as whole home backup and you’re trying to manage through a prolonged outage, you’ll be trying to minimize load anyway. I know I’m stating the obvious, but it’s an important qualifier on the expected impact of having 9.6 instead of the full PowerShare.

That’s beefy service! Good call on the LRA…we have 2 units (upstairs + downstairs) and for whatever reason I had a feeling the larger one would be too much but didn’t know the technical reason. A/C LRAs are ~80 and ~110 so definitely won’t be using the downstairs.

How many breakers and total amps is that? They told me 10 breakers max 100 amps.

Totally agree! Now if you could stack 9.6 outlet KW plus 11.5 PowerShare KW that would be a whole different ball game!

This is a great option. I'm doing this too. Thanks for the post!

Not sure, it's around 250 amps I think, we determined that I can run my whole house without issue... Probably won't be using the air compressor while cooking a turkey and doing laundry at the same time though.

They are fed from the same power conversion system, so it can't happen...
