Powershare Gateway Circuit Breakers?

[Jcoverton]

I had my powershare gateway installed Monday. I have two 200 main amp panels. I had to choose one for the gateway to backup. I had an option to move important circuits to the one panel that would be backed up. The installer put the gateway inside on the wall where service entered the house and put one 200 amp breaker in the gateway. Now one of my main lines pass through the gateway breaker to one of my main panels. All of the circuits in that main panel are backed up but I have to not use excessive power during power outages.

I spoke to the installer again and was told from him that the powershare gateway is rated at 200A but for the light loads install you'd only get 100A to work with. 60 Amps (charger will take 48A) goes to the CT for the charging, and therefore I'd only have the remainder to work with which may be about 6 20 amp circuits I can have.

If they are trying to put anything like the AC, than a 2" conduit would be needed to run the line.

The installer literally goes off the line item from the Qmerit quote where it states up to 10 circuits.

6 20A circuits is about right, but the reason is a little different.
That should probably be 100A of backed up load. UWC / Cybertruck is the source during Powershare, not a load.
48A continuous available @240V / 80% = 120A @ 120V
Or 60A input breaker x2 -> 3x20A output breaker x2

Wish you were in Silicon Valley area. No one over here besides Qmerit has completed their orientation on the PowerShare install.

Smart Charge America is certified in Tesla Powershare and installs in Silicon Valley area. https://smartchargeamerica.com/install/tesla-powershare/

Has anyone been able to get a Tesla certified installer to perform the powershare installation outside of Qmerit and was able to get the Tesla certified installer the 2-4k voucher and equipment that came with the early FS orders? If you can share your experience or steps that would be great.

Our system was setup yesterday - our installer's first. The external power (PP&L) was routed directly into the gateway. I have 2 concerns.
1. there is no way to shut off the external power before it hits the gateway
2. there is no way to simulate a power outage because there is no breaker to turn off before the gateway
(the existing 200 amp master breaker in the breaker box still exists, so we can shut off power to the breaker box, but that is AFTER the gateway).

Questions:
For our configuration - 200 amp service, whole house (whole panel) backup, direct feed from outside power to gateway ...
1. should there be a 200 amp breaker installed in the gateway just before the attachment of the external power?
2. is this breaker an option (ie only needed if you want to simulate a power outage) or a necessity (safety issue, so eg a power surge won't fry the gateway)?

Sorry, not an electrician ... any thoughts appreciated!

[Edit: I am not an electrician, codes vary by region.]
YES!

NOT OPTIONAL, it is required by code! And Tesla installation manual.

Dare I ask, did they convert your main panel to a subpanel? (Separate neutral and ground)

I see an instruction video that if a breaker is installed, that “neutral to ground bonding screw must remain intact, and all other panels must have ground and neutral isolated”. Means nothing to me, but hopefully it means something to my installer. I will check with them. thanks.

Exactly, there must only be one connection from neutral to ground in the system, and that goes at the service disconnect, which the gateway should be (via main breaker) as the first thing after the meter.
The main panel used to be the disconnect and bond point.

The "Service Disconnect" switch is between the Gateway and the main incoming service. Switching it off simulates a power failure.

I shot a short video of my PowerShare test:

Right, but they don't have that breaker (it doesn't come pre-installed):

My installer fixed some other things between the service and the gateway, so maybe my situation isn’t standard. I had two meters originally - he said a long time ago in NH you would pay less $$$ for elecricity to run the electric heat in a house, so a lot of houses had dual meters. My meter was leaking so he took out the two old meters, installd one new one, and installed a 200amp shutoff outside the house between the meter and the gateway, which is what I would use to simulate an outage. Then I had to pick 8 breakers I wanted to run off the truck in the case of an outage (furnace, water pump, two freezers, a fridge and the wifi so the kids don’t melt). So my old panel was turned into a sub panel.

Mongo, cybergus, thank you both! Our installer is coming back next week to insert the 200 amp breaker in the gateway, and also changing the neutral and ground settings in the gateway and the sub panel for that install. Then I’ll be able to flip the switch and try a simulated power outage. Really appreciate everyone’s help. Love this forum.

I reached out to Smart Charge America to go outside of the QMerit network for an estimate. The estimated looked decent and I had spoken to their powershare specialist which was their VP. I had mentioned that I'd like one of their installers come out just to make sure that they can do the job. One thing I shouldn't have done was mention the credit. After I had mentioned the credit and one of the master electricians come onsite, they decided to change the estimates onesand increased it. Needless to say I passed.

I spend time speaking to the VP on the phone and even stated that if I had not asked for a technician to come out to ensure the job can be done and just accepted your initial estimate and signed a contract, you're telling me you would have increased price, he said yes.


These installers are just trying to take advantage of the customers knowing that there is a credit for the FS owners. It's so sad.

Literally a bait and switch tactic.
