All of that said can you actually sell stored energy? As in does the Powerwall support that scenario?
As someone who has solar and is taking the credit on my Powerwall I have not tried but I believe you can ask Tesla to change your setting. Of course doing so would make you ineligible for the credit.

NO.I'm sure this question has been answered many times but I can't find it; for those of you with Power Walls and time of use rate like in this picture, can you buy at the super off peak and sell at peak? Sounds too good to be true is there a catch?

Got it. But if you have a solar system larger than your consumption, can you charge up your power walls during the day and sell all the energy you won't need for the night at peak rate 4-9 pm? At 53c/kWh should be very profitable, no?NO.
* at no point can you sell power sourced solely from your battery (in the USA) unless you have some form of export-agreement. With solar, most places limit your "export" to the amount your solar-panels would have exported daily.
* Tesla strictly blocks sending into the grid. There is some leakage of 30w, but over an hour, it evens out to zero.
Yes, that's one of the big selling points of the Powerwall. We have TOU and have virtually zero peak usage and very little part-peak usage. Nearly all of our grid usage is off-peak. We send all peak production back to the grid.Got it.

Actually, the answer right now is no, if my Powerwalls are representative of the US programming. The Powerwalls will never export into the grid. They will only offset house load. However, they do allow all solar to be exported during peak hours, rather than losing the amount you're using. The amount you can arbitrage currently only is the amount you usually use during peak hours.Got it.

Is this NEM1?Last month's breakdown
Peak usage: -273 kWh
Partial peak usage: -100 kWh
Off-peak usage: 573 kWh
Total NEM charges: $-23.70
And you get off-peak credits for this production? That seems a terrible deal.IWhere I live, peak period is 2 pm until 6 pm. During that time, my house only uses about 4 to 6 kWh of stored energy but my system can export 50+ kWh back to the grid during that same period.
No. If we were to sell back the kWh, we'd only get like 1.5 cents per kWh. Because of that terrible deal, we opted for credits instead. We get off-peak credit for off-peak production, part-peak credit for part-peak production and peak credit for peak production. Basically, we get a credit value equal to the rate they would charge. That way, whenever we use the grid, we pay 8 cents per kWh (usually almost all of our grid usage is off-peak, thanks to the Powerwalls) but when we produce, we get 8 cents (off-peak), 12 cents (part-peak) or 18 cents (peak) per kWh credit.And you get off-peak credits for this production? That seems a terrible deal.

Under NEM2, monthly charges will never drop under ~$10+. Any negative NEM charges are just used for offset at annual tru-up, and then thrown away.
In PG&E Territory, the ~$10/mo minimum charge is not related to which NEM plan you're on. Those are the "Minimum Delivery Charges". They apply to all accounts. Sometime around 2016 these minimum charges were increased from ~$5/mo.Is this NEM1?
