I have a Model Y, as well as solar panels and Powerwalls installed by Tesla. I am quite happy with both. Of course I run the Tesla app on my iPhone. Overall I am more impressed with the way the app supports the home (solar/Powerwall) than the car.
Despite having Tesla solar and Powerwalls, Tesla occasionally sends me email trying to sell me one or both. The one that came today emphasized the Poweralls. It instructed me how to navigate within the app on my phone to a screen that resembles the one I already use for solar/Powerwalls, but it is a Demo. It looks like this.
It doesn't entirely make sense.
Total energy generated for the day is 70.9 kWh. A graph of that shows a hill with no flat at the top, and is down at zero at the right end. Mine has been in operation for over a year and has NEVER had a graph of that shape. The high point I get on that graph is about 7.7 kW, the maximum capacity of the inverter. Any day I have come close to 70.9 kWh the graph has been flat across the top for most of the day.
But the screen shot above shows that that panels are still putting out 5.4 kW despite the graph showing the solar input is over for the day. So is it zero now (graph) or 5.4 (front screen)? Further, I do not believe the area under the curve is close to the 70.9 kWh total shown.
It gets worse. Suffice it to say, the flows don't make sense. The panels putting out 5.4 kW, the house consuming 8.1 kW, 2.0 kW being sent to the grid, and 4.7 kW coming from the Powerwall seems to add up, but why on earth is the Powerwall being drained to send a trivial amount to the grid?
I would say the "Demo" comes close to false advertising, but I don't know if it is the result of malice or stupidity.
