Powershare fails in Utah. Looking for CT owner with powershare.

[Dierk Reuter]

Looking of a CT owner who has working powershare. Ours has never worked. After an extensive review of the home install it was determined to be ok. It was suggested the truck had a problem. Well the truck just came back with a clean bill of health. I just had another test. Here is the report from the powershare support person:

===========================================================================

Hello,

This is ABC with Powershare support. Your case number for the Tier 2 inquiry is: ACXXX.

Per out test, we confirmed that the load in the home was showing only 1.0-1.3Kw before turning off the power to the home via the main breaker. Additionally, we confirmed there were no large appliances such as the A/C or any pumps running which may cause a spike in the amperage. Despite this, with the low load on the home, the Powershare system still reported that it was failing to back up due to an overload.

Additionally, we observed the system try several times to engage backup, however each time it still reported an overload.

==========================================================================

Now I am looking for a CT owner with working powershare. I would love to drive our truck over and see if out truck can power you home. If yes that would finally determine that there is a problem with the home install. If not the problem must be with truck.

Try turning off all the breakers programmed for PowerShare; then see if it switches over. If it does switch over,start switching on the breakers one at a time. At some point you might determine if there is an overload. Mine was installed to enable me to pick what fuses I select. If it is overloaded it will throw a fuse in the gateway box. Have you checked the gateway fuse (switch).

Agree on turning off all load breakers.

Regarding failure mode. The truck inverter will usually trip before a breaker. If a breaker had tripped, it would be readily apparent because that circuit wouldn't work after restoring grid power. The multiple retries also shows that is wasn't a physical breaker tripping.

In an overload situation my house breakers will not trip before the gateway one does. When the installer completed the project, he did a trial run demonstrating what happenes in an overload situation. Sure enough,the gateway breaker (60amps) tripped first. That is why, as a process of elimination,suggested he check the gateway breaker. At least that is my case.

That's quite impressive!
I'm not sure how I could even pull that much current without also charging the truck.

Art 128, Ok that makes sense. So toninight I pulled all the circuit breakers. House went to zero kW. The truck and noise from the gateway went into the cycling mode as it did before.

Attached is also a short video from inside the CT. It shows one cycle. Once I review frame by frame I can see:

Powershare Retrying Discharging 0kW
Starting Powershare Home Backup Discharging 0 kW
Powershare Active Discharging 0 kW
Powershare Active Discharging 4.3 kW
Powershare Active Discharging 3.8 kW
Powershare Retrying Discharging 0kW

I am not sure what in the House would pull 4.3 kW with all the circuit breakers off. But 4.3 is also not above specs. So I still don't see why this doesn't work.

Again, I am looking for someone with a working powershare install. I would love to drive over, do a test with our truck. If that works fine the problem must be with the house.

I like your test plan and would do the same. I’m unfortunately in Phoenix and have a powerwall 3 setup still waiting for software love from Tesla to do PowerShare.

Something is seriously not right. There shouldn't be any draw with breakers open.
What is your house setup? Full/ partial backup, solar, air conditioning?
Can you post photos of the Gateway and breaker panels with the doors open?

Here you go. Straight forward. There is a sales person in Plesant Grove who owns a cybertruck and has working powershare. However as an employee of Tesla he can not help figure out if this is a problem with the truck or the house. The service center doesn't have a full test harness to determine with certainty that the truck is working.

So again if anyone in a 10 hour driving radius of Park City owns a cybertruck with working powershare I would love to stop by and determine if our truck can power your house.

Bueller?

 

[Dierk Reuter]

Thank you for the kind response! I am unable to find "Bueller" on the map?

Is it a sub panel that is being backed up? (photo of that)
When you are testing, is it by using the off grid toggle in the app or by flipping off the main service breaker? If the app, try flipping main breaker instead.

Do truck outlets all work ok?

I’m about 13hrs but all that sounds strange.
My powers gone out about 4x now related to a line fault, wind, another line fault and a failed transformer.
The line faults were interesting as if almost had a feedback loop causing all my APC battery backups to click on and off but other outages did not cause this.
The service line was installed in the 60’s and I am 0.5 miles from a substation. I suspect it was not on conduit.

I know for me it’s items that add up like fridge/freezers, well pumps and HVAC units. My understanding is we have a peak support of 110A and 48A continuous. Most my house summer idles at 400-800w. I notice after a power trip like that though sometimes all I he appliances kick at once. My house and shop sub panels are fully supported right now but the electrician had to do a bit to separate ground and common and he triple grounded everything on inspection.

Mini fridge
Large fridge
Shop Fridge from 1947 ?
Large chest freezer
2 well pumps
Misc computers and networking
(2) heatpumps
Rest on propane

One outage the truck was charging and almost instantly brought the house back online.

i don’t know if there is anything extra you could glean from service mode after a failed PowerShare backup in the truck but might be worth a look. Even in the Tesla app for a brief moment I see an error but it goes away.

There is also the Tesla installer app I think called Tesla One. It connects wirelessly to the gateway and may add more detail. The electrician gave me an overview case I had to reset something.

Sounds like you should do an overnight Cybertruck Test Drive, plug it in and see what happens.

Tesla actually remotely enables PowerShare after your install so not sure it would work out of the box.
