Any Update on PowerShare Integration with Solar Panels?

[xmario]

So just to clarify, is this solar software update supposed to allow my solar to charge my CT while in powershare and off grid?
I have Tesla solar (inverter) without PW, and trying to avoid purchasing the PW if my CT will charge from solar while backing up the house via powershare gateway just as a PW would function.
During the hurricane season power is out for days in FL.
What did I miss?

my understanding is for non Tesla solar systems the software update will allow during a grid outage the CT to power the house similar to a Powerwall. I don’t know if this update will allow your solar to charge your CT.

I would think if your solar does not power your house during a power outage now, then it won’t charge your CT. Thus another software update to the PowerShare gateway would be needed.

Ideally, yes solar charges Cybertruck and Cybertruck inverter does the frequency and voltage adjustment needed to control variable output solar inverters. At 80%, my truck was outputting 118V, which could be a sign of this behavior.

Easier to implement, but less useful is if it outputs a frequency high enough to disable the solar.

Most solar is grid interactive and not grid forming. From the solar's point of view, the Cybertruck is the grid and so solar will try to add energy to the system.

So we just had a QMERIT partner come out to quote us.
Rough overview of what we have:

• 5 Tesla Powerwall 2's (3x on a 200amp panel and 2x on the other 200amp - house has 400 total)
• The 2 PW's are on a V1 Tesla Gateway
• The 3 PW's are on a V2 Tesla Gateway
• We have an Enphase system for solar (2 IQ Gateways with a total of 75 Microinverters)
• Whole house is backed up with no sub panels

The issue we've run into is the PowerShare for CT will require the Tesla V3 Gateway so our old Gateways do us no good. The main issue, max the CT can output is 60AMPS and because our whole house is backed-up by the Powerwalls, the CT cannot be integrated to help supplement our existing setup (current V3 Gateway limitations and capabilities of the CT output limits).

We had hoped to capture more energy in the summer months here in KY vs selling back to the grid for .005kw (we pay roughly .11kw). We're told upcoming firmware releases may resolve some of the limitations. It is rather frustrating however, having an existing Tesla setup seems to have set us back rather than ahead, depending on how you look at it. Hoping this will change or perhaps the information we were provided is lacking? Appreciate any insights form the community.

I wish Tesla would send me a Valentine's day card with a note that the software is ready.

Another message today in response to them asking me what gateway I have.

Okay, great. We have been told the powershare will be available this week for the customer with solar and a Gateway 3V.

 

[mbrockus]

I hope that’s accurate. Will be nice to have it available for when the spring storms start rolling through.

If you have Powerwalls already all you need is a Wall Connector (once Tesla releases the software)
No 3V Gateway required.

For Customers With Powerwall

If your home is equipped with Powerwall and home charging, you do not require any additional equipment. Powershare Home Backup functionality with Powerwall is expected to be available later in 2025 through an over-the-air update. All Powerwall models will be compatible with Powershare Home Backup in the future.2

Our preferred home charging solution is the Wall Connector or the Universal Wall Connector on a 240 V circuit, but any generation of Wall Connector is compatible with Home Backup if using Powerwall. The home charging system must be backed up by Powerwall to enable Home Backup.

This is very exciting and appreciate the knowledge share. Im curious though, why is a "certified" Qmerit electrician telling us we would have to have a 3V Gateway (even with a future firmware coming), shouldn't they know the basics... especially considering they are quoting for and on behalf of Tesla?
Thanks again @mongo !

Yeah, not all installers are up on how it works. I had to go back and forth multiple times with the Qmerit one until they could finally give me a quote on the setup I wanted (that they didn't think was possible).
Not planning on using them. You can go through other Powerwall installers.

Thanks!
I reached out to the outfit that did our solar and Powerwalls, they confirmed it is doable and will be quoting the job. Not sure what I do bout Qmerit. Will report back with updates. Thanks again.

No. The inverter on the truck can either provide power, or be used to charge the truck. But not both at the same time.

Got this update from them today when I asked if it was released to anyone yet.

Good morning,

Not yet, I am still waiting for an update. The software version you will see is 25.18.

To those who have PowerShare installed but who believe that it doesn’t work until the solar software update is installed.

I think your installer f-ed up your install. I have mine installed six months ago and though the solar won’t charge the CT I can attest the power backup works just fine.

We’ve had six grid failures and the CT has powered the house every time. Early on we had numerous events where charging the CT would trip the breaker but that was fixed with a replacement breaker.

But there are a lot of people that are in that boat, from different regions and installers. Is that really possible?

I have actually been able to contact Tesla (miracle of miracles) and they indicate it awaits a firmware update from their end. Not a screwed up installation. Now, if maybe somehow they didn't know you have solar, somehow you got the "enable button" added to your CT. The CT has to positively enable Powershare (you wouldn't want your truck unknowingly donating its battery energy to some charger without your say so).
