    Are these operating modes possible?

    I just saw on another post that there is an option to tell the app your utility and rate plan (go to Performance, scroll down to Solar Value, and tap on the utility and rate plan at the bottom of the page). I didn't know that option existed. If Tesla wanted to be REALLY SLICK, they'd add an...

    Are these operating modes possible?

    The Powerwalls would get charged from the excess solar that the home doesn't consume in the morning. There would need to be some AI involved like in Balanced mode where the system would recognize if there isn't enough solar being diverted to fully recharge the Powerwalls before the next Peak...

    Are these operating modes possible?

    I'm an excess producer. I don't mind pulling from the grid during off-peak when no solar is being produced. I'm only compensated ~$0.03/KWh for the additional throughput from the Powerwalls.

    Are these operating modes possible?

    The results of days 2 and 3 were pretty much the same as day 1. I don't see any evidence of a trend that would lead me to believe that this would improve if I gave it more time. At this point I don't see any way of accomplishing the following: 1) Only allow discharging the Powerwalls...

    Are these operating modes possible?

    Increasing the reserve won't work for me unless I wanted to manage it daily (which I don't). I don't think there are any settings in Balanced mode that will make the Powerwalls stop discharging at 9pm and not discharge again until 4pm the following day. I think the gap is just too big.

    Are these operating modes possible?

    I should clarify the above only applies to the Peak hours. Cost Savings mode still incurs unnecessary NBCs during the morning by prioritizing Powerwall recharging over home consumption thus requiring the house to draw from the grid while the Powerwalls are recharging.
  7. R

    Are these operating modes possible?

    You're correct now that I think about it, when solar when solar is prioritized to the grid and the home is running off the Powerwalls then there aren't additional NBCs but there is unnecessary discharging of the Powerwalls since the home could be running off solar. So I want the solar...

    Are these operating modes possible?

    My conclusion so far is my goals can't be achieved with the current operating modes. But several people have said I should try different modes so I'm trying to go into this with an open mind.
  9. R

    Are these operating modes possible?

    Yes, but you don't care if your Powerwalls don't last beyond 10 years. I'm trying to maximize their life since they are mainly for backup and I don't want to have to replace them sooner than necessary.
  10. R

    Are these operating modes possible?

    That's where I started from. And it works great except solar is prioritized to the grid instead of my house. So I incur unnecessary NBCs and Powerwall discharging. That is what I'm trying to eliminate. But, unfortunately, Cost Saving looks to be the least of the evils.
  11. R

    Are these operating modes possible?

    I have my reserve set at 50%. This lets me get through the hottest/coldest days before hitting my reserve during peak hours (4-9pm). Due to a combination of a mild day, prioritizing solar to the house (good), and and drawing from the grid during peak (bad), my SOC was above 90% at 9pm...

    Are these operating modes possible?

    T The problem with starting Peak earlier in Balanced is it will send all solar to the grid and none to the house just like Cost Saving. If I wanted that I could just stay in Cost Saving to avoid discharging the Powerwalls Off-Peak.
  13. R

    Are these operating modes possible?

    The only time I want any power coming from the Powerwalls is 4-9pm (unless there is a power outage).
  14. R

    Are these operating modes possible?

    Results of day 2 pretty much the same as day 1.
  15. R

    Are these operating modes possible?

    I don't - It was a typo - It was pulling from the Powerwalls during 8-9pm - fixed the typo.
  16. R

    Are these operating modes possible?

    Day 1 of Shoulder set to 4-8pm and Peak to 8-9pm in Balanced mode results: During the day the house was running off solar with the excess going to the grid (good). At 4pm the house continued to run off solar with excess going to the grid (good). Around 7pm the solar couldn't keep up with the...

    Are these operating modes possible?

    Cost Saving with Shoulder set to 4-9pm and 50% reserve worked just as expected. From 4-9pm the house ran off the Powerwalls and all solar was sent to the grid. At 9pm the house started running off the grid with the Powerwalls at 80% SoC. The Powerwalls remained at 80% SoC until solar started...

    Are these operating modes possible?

    I might try Balanced with Shoulder from 4-8pm and Peak from 8-9pm again and try to leave it alone for a few days. Its just really hard to watch the house running from the grid during peak hours and running off the Powerwalls off-peak. But I think it is reasonable to think that if the system...
  19. R

    Are these operating modes possible?

    Yep, that is where I was but I thought I'd give Balanced mode a fair chance. I'll likely wind up back on Cost Saving mode with Peak set from 4-9 pm and Off-Peak all other times.
  20. R

    Are these operating modes possible?

    I tried Shoulder from 4-8pm and Peak from 8-9pm (see post #64). The problem was it was drawing supplemental power from the grid during Shoulder when the solar couldn't keep up with the house demand.

    Are these operating modes possible?

    Yesterday I had Shoulder (Balanced) set to 4-9pm. and everything else Off-Peak At 4pm it started sending all solar to the grid, none to the house, had ran the house off the Powerwalls. At 9pm it started running off the grid with the Powerwalls at about 75% SoC. Before I went to bed, I...

    Are these operating modes possible?

    A few people have said that the Shoulder period in Balanced mode will prioritize the house and send excess solar to the grid so that is why I'm trying it. Its not just the NBCs I'm trying to reduce, I'm also trying minimize unnecessary cycles on the Powerwalls.
  23. R

    Are these operating modes possible?

    Update to how my system is working with Shoulder set to 4-9pm and everything else off peak in Balanced mode. Yesterday there was no power drawn from the grid during 4-9pm (good) but all solar was sent to the grid and none to the house (bad). After 9pm my house ran from the grid (good) until...

    Are these operating modes possible?

    I think scripting solutions are a little beyond my skillset. If I did script something, it seems like the best way to accomplish my goals would be to change operating modes based on times of the day. I believe a combination of the different modes are capable of accomplishing what I want...

    Are these operating modes possible?

    My annual solar generation is slightly greater than my consumption in KWh. I was close to zero true-up before Powerwalls but then I then I got thrown into EV2A because of SGIP. So I'm just trying to use the Powerwalls enough to get back to zero true-up since my main concern is backup and I...
  26. R

    Are these operating modes possible?

    Yes, I agree, we have different goals. My Powerwalls are mainly for backup. I only want to use my Powerwalls to the extent necessary to achieve a $0 true-up. It's just strange that there isn't an operating mode to achieve this without incurring unnecessary NBCs and cycles.
  27. R

    Are these operating modes possible?

    Getting rid of shoulder would defeat the whole reason for me to use Balanced. I want to prioritize solar going to the house with the excess going to the grid during peak hours. My understanding is Peak will send all solar to the grid even in Balanced mode. Another problem is that Balanced...
  28. R

    Are these operating modes possible?

    I can try leaving it on Balanced mode for a few days to see what happens, but it is hard seeing it draw from the grid during peak period when I've got it set to Shoulder. If that's what I should expect then Balanced isn't the right mode for me. In Cost Saving mode I had usually no problem...
  29. R

    Are these operating modes possible?

    Well, that didn't work either. I had Shoulder set to 4pm to 8pm and Peak at 8pm to 9pm running Balanced mode. In the morning things were going good. The solar was prioritized to house consumption with the excess charging the Powerwalls, and insignificant draw from the Powerwalls. Once the...

    Are these operating modes possible?

    If it works this way for me I'll be happy. I can tolerate a little discharging during off-peak. But if it does a lot of off-peak discharging or a lot of see sawing then I'll go back to Cost Saving.

    California Utilities Plan All Out War On Solar, Please Read And Help

    I think it was a tactical on their part to try to remove the grandfathering of current NEM customers. This bill might have snuck through if that wasn't part of the bill. I wouldn't be surprised if a revised form of this bill without retroactive NEM impact tries to fly under the radar in the...

    Are these operating modes possible?

    I have my reserve set to approximately match the end of peak on the highest demand days. However, about half the days in a year my demand is only about half my reserve. My concern is those days the Balanced mode will try to discharge to the reserve limit during those days. Additionally, I had...
  33. R

    Are these operating modes possible?

    Well, that didn't work. Cost Saving Peak and Shoulder appear to operate the same with regards to sending all solar to the grid. I also tried setting Shoulder to 4pm to 8pm and Peak to 8pm to 9pm. Same results during Shoulder. I'll give Balanced a try again to see just how bad it discharges...
  34. R

    Are these operating modes possible?

    That's pretty much how I have it set now with peak ending at 9pm and my reserve set at 50%. On the hottest or coldest days it just about makes it through peak. Then on milder days it stops discharging at 9pm with more SOC that is carried to the next day. But I don't understand how you think...

    Are these operating modes possible?

    I didn't get Powerwall PTO until September. However, my Powerwalls were online since the install (that's the way they did it).
  37. R

    Are these operating modes possible?

    I'm going to try this with Cost Savings mode. I did a quick test and part peak was acting like peak. I'll let it go longer at 4pm unless I see something really unusual (like charging from the grid or sea-sawing back and forth between charging and discharging). I don't want Balanced mode...

    Are these operating modes possible?

    No, true-up in September.
  39. R

    Are these operating modes possible?

    I had my solar installed September 2019. I got Powerwalls a year ago in June. I had a $200 credit for excess generation at my true-up last September. I will likely cross over to net surplus this month (I owed $66 cumulative in my last statement).
  40. R

    Are these operating modes possible?

    I don't think that will do what I want. It is still set to peak from 4pm to 9pm so it will still divert all solar to the grid during that period. I want the house to be the priority during that period with the excess going to the grid during that period. I want all power to come from the...
  41. R

    Are these operating modes possible?

    From what I understand, self-powered will use the Powerwalls at night which I don't want to do. And there is no option for peak periods, and I definitely don't want to draw from the grid during peak periods unless I've hit my reserve.
  42. R

    Are these operating modes possible?

    If I were to remain in Cost Savings mode but change my current peak hours of 4pm to 9pm to partial peak, how should I expect the system to react? Would solar be prioritized to my home and then the grid? Would my system draw from the grid during this period (don't want that)?
  43. R

    Are these operating modes possible?

    That is my post and let me clarify why I'm asking. I agree that running the house off solar during peak does not maximize savings as long as NBCs, Powerwall cycle life, and the ~$0.03/kWh wholesale rate you are compensated for excess generation aren't taken into account. Once you have...
  44. R

    Are these operating modes possible?

    Cost Saving mode will send 100% of the solar to the grid and run the home off the Powerwalls during peak. I was also also looking for a setting that would prioritize the home during peak and send the excess to the grid (and run the home off the Powerwalls when there is insufficient solar)...

    Are these operating modes possible?

    I'm trying to understand how the fake shoulder would help. I'm on cost savings, have 9.6kW solar, 2 Powerwall 2s, and set my reserve at 50% for power outages. I'm on EV2A and it has become apparent I'm going to overshoot my goal of $0 true-up. I decided to remove my shoulder rate to and...

    Are these operating modes possible?

    I'd probably like balanced if it had an option to never discharge the Powerwall during off-peak hours.
  47. R

    Are these operating modes possible?

    This time of year you're probably right. But winter this isn't the case for me. While there is currently no data on how long Powerwalls will last, it is a reasonable assumption that the Powerwall life will be similar to other lithium NMC chemistry batteries and thus life is driven by cycles...

    Are these operating modes possible?

    This does three things I don't like: Depending on system size and conditions, it increases the likelihood that you won't hit 100% charge prior to peak rates. This may be compensated by the AI but I didn't stay on it long enough to find out. It increases the likelihood that you won't have...

    Are these operating modes possible?

    I tried balanced but it will discharge the Powerwalls during off-peak which is not what I want.
  50. R

    Are these operating modes possible?

    Is there a cost savings mode that prioritizes the home over the grid? I use cost savings and my house never runs off solar during peak.
