⚡️ PowerShare Install, Specs, Details confirmed! No load shifting (for now)

[cgladue]

In my particular case I live in a rural area where power tends to flicker on and off rapidly about 3-6 times before the power completely goes out. Sometimes it just flickers and then stays on. I don’t know the exact reason it happens on all occasions so it’s pure speculation, but storms definitely are a cause sometimes, sometimes not, aside from that the guess would be a tree falls on a line or brushes against it roughly or someone hits a power pole in a car accident. The point being it isn’t predictable enough to be “only” when a storm approaches.
I have enough electronics in the house I’d rather not have ruined by weird power fluctuations and a whole home UPS would solve this problem perfectly. I’m not currently concerned about keeping power for any extended period of time, I have a portable generator I can use for the fridge and freezer if absolutely necessary, and nothing else is absolutely necessary beyond those items.

At some point in the future I would like to entertain the thought of getting solar and powerwall for decreased energy costs, but I’m already planning to get a Cybertruck in the next year. If Cybertruck can serve as this whole home UPS for just a few minutes to allow enough time to turn off electronics properly, that’s all I am concerned about. That would allow me to extend the timeframe of getting solar and power walls much farther into the future.

sounds like you need to install a whole home surge supressor and youll be fine. simple install

Got it - thanks for the detailed explanation. Very helpful. So the question is whether the $2600 of hardware + cost of Tesla certified install is worth the automated backup and slightly more output?

Did I read here right that you cannot get your own electrician to install the power sharing setup? My father in law is a licensed electrician and installed my 2 existing wall connectors. He would almost certainly be able to setup the inverter/universal setup, but why wouldn't he be able to?

I don’t think so, but if you get a call from the company assigned to do the assessment, perhaps you could work it out with them where they get the hardware and your family does the install? Not sure

It absolutely could, depending on the installation requirements. But up to $4k is included.

Yeah not included on the AWD - so if this is important to a person, and I assume it would be for most because who doesn't want a home battery backup from their vehicle, it would cost around $4k extra (on top of $100k) to actually make use of the "included" powershare and universal connection hardware with the AWD variant.

Separate question. Cybertruck has a 123kWh battery. Powerwalls are 13.5kWh which means the truck is equivalent to 9 powerwalls in capacity. Would 9 powerwalls really only last 10 hours? What am I missing with that?

the length of time they will last depends on your usage .. but it is a fact that the truck has 9x the capacity... i believe the outlets in the bed cut out at 20% so if you are using the NEMA 14-50 you cant take it down to 0% and im sure it wouldnt let you do that anyways, so the total power available is likely around 98.4 kWh (100 - 20%)

but for an average home in the USA that uses 26 - 33 kWh a day that means you can run the house for 3-4 days on the truck if its 100% charged

 

[cgladue]

but also the bed outlets are limited to 9K watts

limited to 40 amps... the wattage you can get depends on how much the voltage sags below 240v ... if you are drawing 40amps and the voltage sags to 220v then thats no longer 9600 watts its 8800 watts.

but its current limited since the specification of the plug is 40 amps max.

From what my local Tesla install rep told me, the outlets in the bed put out 9kw, the Universal Wall Charger with the gateway and CT will put out 11kw. My house is just a typical 2500 sq ft house. He said I need 22kw to run the whole house. So I will need to either add a Powerwall Gen 3 or two Gen 2's plus the CT to run the whole house. Or only run only items that would equal 11kw. Like just my HVAC possibly.

He also said you could just install any brand transfer switch to your home and plus the CT from the bed outlets to the transfer switch and get 9kw without the Tesla PowerShare equipment.

 

[Cybergirl]

I haven't been told if I qualify or not, but regardless I don't want the Power Share system.

1) ComED in Illinois is extremely reliable. In 12 years I can only remember one blackout that lasted more than a couple of hours.

2) I have a 6.8 kW solar system and 9.6 kWh battery bank to a Sunny Island inverter feeding a protected loads panel the reacts instantly to a grid power glitch. The battery will power lights and critical loads for 24 hours. In summer, solar will replenish the battery extending the backup period for days.

3) My Cybertruck will not always be available as a power reserve when I need it most. I spend the winter months in Arizona.

4) Spending an additional $4k - $5K for installing Power Share increases my CT cost to $107K - $108K. The AWD CT FS price is already a stretch.

Six months of Supercharging is better than nothing, but why not give $2400 in Supercharger credits good for use on my CT for life?

Your house draws 22kw an hour or a day? I was gonna say, are you running a grow house? lol people are getting this mixed up. the truck will run at 9kwh with 40amp cable and up to 11kwh with Power Share. The total wattage it can draw is approx 80 of Cyber Truck battery. So If I was drawing 1kwh = 1000 watts an hour then my home can operate off of the CT for approx 4 days. Just want to make sure everyone understands that.

Flickering lights are often caused by the grid testing for faults and switching to alternate routes.

That completely is dependent on the load. 10 hours or 10 days are both realistic. And so is 0 hours.

From the grid, In my case, I use on average 70kwH a day (averaged 1/1/23-12/31/23) which is a lot, but the house is a bit larger and I have a TON of electronics + 2 EVs. I guess this would give me about a day, but not really in practice since the truck couldn't power everything all at once. I would have to shutoff significant amount of breakers to ensure i stay under the 11kWh it can actually supply. This would likely mean I would get 2-3 days out of it. Think that clears that up - thanks.

Totally makes sense in your case. I live in the woods and while we don't have power outages often, we've had 3-4 in the 3 years I've lived here (one on Christmas morning once). How does a 9.6kWH battery power critical loads for 24 hours? We're talking about CT only being able to power in some cases whole house for 10-24 hours with 123kWh?

That completely is dependent on the load. 10 hours or 10 days are both realistic. And so is 0 hours.

I finally got my PowerShare install scheduled and wanted to give details here since it’s been a big unknown.

AWD: PowerShare gateway and wall charger included. Installation is out of pocket.

Cyberbeast: PowerShare gateway, wall charger, installation included.

Hardware is shipped to the installer after the price quote is accepted and install date scheduled.

Permitting with utility company required (part of installation cost in my case).

Cybertruck can provide 48 amps and about 11kw of continuous power during an outage which is about 10 hours with full battery. Realistically will pull half that or less during the day and much less at night which pushes it to 1 full day. If you have solar (as I do), it works in tandem so can extend to several days of backup.

Currently does NOT provide load shifting. Load shifting is a feature of the powerwall to try and avoid high rate time of day from the grid and instead use battery during that time. At this time, due to regulations and agreements with utility companies, this can only be used when your home is disconnected from the grid (outage, or perhaps if you go manually disconnect).

The hope is once a bunch of these are installed and the regulations update, they could enable load shifting with a simple software update.

Prices to install will vary a ton based on the work needed and I’m not going to speculate on that, but assume in the thousands.

POWERWALL AND CT POWERSHARE DUPLICITY:

I had started going down the path on a Powerwall quote just prior to my Cybertruck Order (12/28/23, with Q1-24 delivery)..but with my Foundation Series order and now coming with PowerShare capabilities and included components (Gateway, PowerShare connection, etc) it seems like the Powerwall quote I just received has some duplicity in that I am paying for the same components needed and overlap on installation!?

any ideas? I have been trying to get answer from my Powerwall rep but nothing yet.

Here is Powerwall quote:

I would wait to order the powerwall. The installer for my PowerShare also is a Tesla PowerWall installer and he said most of the labor is the same, so it would make sense to do them at the same time to save money. Once they come out for your PowerShare, maybe you can tell them you want to do PowerWall at the same time and they can do it that way?
