Any Update on PowerShare Integration with Solar Panels?

[Nolacyber]

I have non Tesla solar panels on my house. When my PowerShare was installed o was told that in the event of a daytime grid failure the PowerShare would not allow the solar panels to recharge the Cybertruck battery.
The installers thought Tesla would be updating g the software to enable use of the solar panels.
Has this update occurred?

If you are powering your house from the Cybertruck through PowerShare the inverter can’t go both ways at the same time, charge and discharge??? Is that the question or will solar charge while solar is powering the house as well. Charge on Solar with grid down?

 

[Nolacyber]

Normally,while the Cybertruck is not plugged in, my 6 kw of solar panels provide most of the house’s power needs (a lot of sun in the south). Because I don’t have a powerwall, if the grid goes down my solar panels do not provide power to the house. This is a safety measure to ensure that the solar panels don’t back feed into the grid (to protect power line workers)
Since the Cybertruck acts just like a big powerwall it was supposed to enable solar to continue providing power in the event of a grid failure. This would effectively extend the backup power avaialable from the Cybertruck.

I am in the same boat. Still no button on the truck to enable powershare. Also, I have no Powerwall. But I think there is a bigger problem. In a power outage, you can't send excess solar back out to the grid. So for example, if your house is pulling 3 kW, whether from the truck or from solar, but your solar is producing 6 kW.... what does your electrical system do with the excess power? Some people have switches to heat water, for example. But the Tesla Gateway isn't designed to dump extra power. Probably best solution is to disconnect the solar during an outage, since the Cybertruck inverter can't use it anyways (it either allows charging of the truck, or providing power out...but not both at the same time).

I have an Enphase controller on my 6kw solar panels; the enphase moderates the amount of power generated by the panels; eg. Sometimes the My Home page on the Tesla APP shows the house consuming 1kw of power while the panels are capable of producing g much more, so the Enphase turns the microcircuits on and off.

I understood the PowerShare would integrate with the Enphase and indeed the installer QMerit) showed me the wire that will integrate once the software is updated.

if you don’t have PowerShare activated on your ct you may have a bigger problem.

The solar inverter will shutdown before it overvoltages the house. In other words, just because it can put out 6kW doesn't mean it will. Fancier inverters reduce output in response to the voltage or frequency versus just cutting out. That's how they work with AC coupled Powerwall 2s.

I have Enphase but haven’t heard of this. Can you give more info and links please?
I am in the same boat as everyone else, got PowerShare installed gateway and no powerwall with none Tesla solar. Nothing is working yet. Was told I am waiting for some update that was supposed to come by end of last year.

Any update on the software update. Anyone with non Tesla solar backup from truck working?

I also have the Enphase solar system. Had my PowerShare gateway and universal wall connected installed and initiated by the installer about two weeks ago. Have the wall connector showing when charging on the Tesla app as well as the app showing how much kWh s the solar system is generating and how much if any additional electricity is being used from the grid. Backup not working with a manual breaker off simulated power outage.

I received this message yesterday from Tesla when asking for an update.

Yes, we are getting closer. They are testing the software one more time and will be starting to push out the firmware next week to customers with solar. You will receive an email when it is pushed out to your system.

Would have been nice to have this morning.
It’s been installed at my house for over 3 months now and still waiting.
Lost power in the early morning hours. Woke up to a cold dark house. I was able to get my generator on and running for a few hours before power was restored. But that required me to get dressed and go outside to plug everything in and turn it on. Instead if the power share was working I would have woke up to a warm house and a hot cup of coffee.
Waiting and waiting. Let’s hope they get it working soon. Only a few more weeks of winter to go.

Great news!

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.

Is your Solar on the backed up side of the Gateway?

I am still waiting for my Powershare to be enabled, to handle my solar too. But I got tired of waiting. So I installed a 50 Amp generator socket on the wall in my garage on a 60 A breaker on my sub panel. Just disconnected from the grid manually for a test. Hooked a cable from the 240v outlet in the back of the truck to it, and am powering the house from the truck just fine.

Sure, but that's 40A (9.6kW) vs 48A(11.5kW) and needs to be toggled every 12 hours.
It's also not up to code without an interlock between the grid connection and the generator backfeed.
