Sadly both are blinking green. The gateway needs to be RMAd and won’t be replaced until next week. Dagger. Has anyone else had this experience? Any suggestions for when the installers do test the system?

Sorry no. I hope your RMA happens quickly without any further drama. On the other hand, you would have had to wait for city-inspection and PTO, so doesn't make much difference in time. The important part is physically getting the PWs.Sadly both are blinking green. The gateway needs to be RMAd and won’t be replaced until next week. Dagger. Has anyone else had this experience?

Not a dumb question. There are two strict configuration of PWs. (a) Solar and (b) Non-solar. If you have attached solar, PWs is charged by renewables/solar. If you are non-solar, you are allowed to charge from grid. No other options between... yeah against logic. There's a storm watch feature is triggered by Tesla to allow charging from grid when a storm is predicted on the horizon... so not "exclusively charge from solar."And a dumb question - if the sun doesn't shine for a week, will they charge up from the grid at night when power is cheap, or do they exclusively charge from solar?
When you say 'can't export solar', are you talking about California or something? Because we have net metering in Virginia, and we export everything, of course, that's not needed for the house at that second. And I expect to do the same after the PWs are installed (next week, btw). Everything not needed to run the house or charge the PWs goes back to the grid.Not a dumb question.

The special option on the app for aggregate program / demand response only applies to non-solar. They still can't export solar to the grid thought (again against logic). PW system can be told by the utility when to absorb excess grid power (excess solar) so the utility doesn't have to pay neighboring states to take power. <-- what the Tesla Energy phone support said.
Axe that part about 'can't export solar.' (This is California and not Hawaii.) Sorry, I meant the PWs are not currently setup to discharge to the grid. The stored energy is intended for self-consumption.When you say 'can't export solar', are you talking about California or something?

Or am I missing something here? Thanks!
Pretty good, about a year shorter than mine.Reservation 3/1/19. Install 5/14/19.

Well this is unfortunate. I was planning on charging the PWs off of the grid at night to be sure to cover the morning shoulder.
Is there a way to trick the PW into charging off of the grid when you have solar as well?
That person's carrier is Telestra which is Australia.Is this video now outdated due to updates? Very "manual" but an option.
Good point.There isn't, but it'd also take quite a bit of power usage for the savings to offset the 30% tax credit you'd have to forgo if you did this. I also suspect that this restriction may be lifted after the five year vesting period for the tax credit. Powerwalls in other countries already can charge from the grid when installed with solar.
Dang. Let me know if you figure out a way to bypass the restriction.That person's carrier is Telestra which is Australia.
Australia looks like it uses ~230V 50Hz which would be incompatible with the USA split-phase 120V/240V 60Hz, The software in the PowerWall seems region-locked, so the video is basically irrelevant.
Your solar production is certainly not being wasted in the current configuration. During times when your solar generation exceeds house load, the difference (yellow-blue) is being fed back to the electric grid. It is at least helping someone else, and hopefully you are getting credit for that net generation at the same rate that your power company would charge you for it. So you are already using the grid as an infinite-capacity battery. If that is working for you, then the PW will allow a bit more time shifting as you describe, but its cost benefit would be maximized on a time-of-use plan (which you should already be on if you have solar).This is a picture from Neurio page that monitors my solar generation (yellow) and my house consumption (blue). If you look, you can see the solar production is "wasted" because the sun shines when my house isn't using the power. I'm hoping the powerwall will solve this - store the energy and discharge during this peak time and cover my usage when the sun isn't shining. Really looking forward to the PW install. But if it doesn't work, its going to be a costly error... (took this screen grab just now, so this is "live") with no PW installed yet.
