The reasons I choose that is on ev2-a, the rates are higher from 3pm to 12am. I went to 1am to since I could not get the 12am cleanly. So I just wanted to get max creditsOk, I’m going to try the 3pm to 1am.

On TOUC we only have peak from 4 to 9 but the more I’m on the batteries at night the better. What setting do you use, balanced or cost saving.The reasons I choose that is on ev2-a, the rates are higher from 3pm to 12am. I went to 1am to since I could not get the 12am cleanly.

Ok, thanks I’m using cost savings because I thought I would save some money. I’m going to leave my settings as they are thru this month and see where I’m at, may make a change for June.balanced
On my wish list for features would be the ability to put the actual prices in the peak, off peak, and shoulder.My billing has peak rates from 4-9 at $0.41 and off peak at $0.17. So I set mine to Balanced with peak from 4-9 during the winter. I run off the battery during peak and impermanently during the night until it reaches my reserved settings.
During the summer I set my peak to 7-9 and shoulder from 4-7. This way I still use much of the solar during the 4-7 hours with the battery providing the balance that solar may not provide
You harp on gas heat a lot, but it's really not a thing... do you complain about the person who lives in an area that doesn't require AC in the Summer? Or someone who doesn't need heating in the winter (like AZ)? How about people who don't have pools?Because I need to send as much power back to PGE for credit so it can be used during winter. For folks who have gas heat, one never has to worry about it. But for folks like me that have electric heat, it actually takes more than AC. So, without NEM2, and 99% electric, solar would not make any sense from an ROI.
On just one PW, good luck.Hi all,
I've got a recent solar installation with a single PW2. I'm in the Bay Area, on PGE's ETOU-D plan. So far I had set it up in Advanced mode - so that the battery only provided power in the evening during the peak rate window, which is 5pm-8pm on weekdays only. This seems suboptimal - My battery goes down to about 70-75% in these 3 hours.
The 'simple' question I have is: If I use 1 kWh from the grid, and return 1 kWh to the grid, is it a net zero $ game.
OR
Is PGE doing the math has 20cents (1 Kwh from the grid) minus 3c (1 kWh back to the grid) - so I'm 17cents in the hole? (Rates may not be real - just for example's sake)
Depending on clarity on the above question (Is it $0 or -$0.17?) - I will need to tweak my plan to MAXIMIZE being self-powered.
Note also - that off late, the energy production for me has been huge. and I'm giving back unto 35-40kwh back to the grid, daily. Also, if it matters, I expect to run my central AC, intermittently during the mid-Jun thru end-August - that will change my consumption profile for sure.
Any tips / pointers? My primary objective is to MAXIMIZE $ savings, or ideally, the PGE refund at the end of the year.
Thanks in advance!

Depending on how "recent" your install is, the algorithm might not have learned your usage profile well enough to do the projections.Hi all,

No. There are two different measurements going on. One is measuring the value of energy when you give it to the grid in $. The other is the total amount of kWh that you produce vs use during your yearly (prior to true up) period. This is where NBCs and other factors are considered.The 'simple' question I have is: If I use 1 kWh from the grid, and return 1 kWh to the grid, is it a net zero $ game.
I LOVE that basically my PW's are powering my house like 23 hours a day. I have ZERO concern about backup power in the summer, once the sun comes up, the PW's get recharged fastThe main thing I don't like about Balanced is it will draw power from the Powerwalls during off-peak hours in the morning. Having backup power was my main objective of getting the Powerwalls and I want them to have as much reserve as practical during off-peak hours.
Cost savings mode prioritizes recharging from solar in the mornings and then diverts power to the house/grid once the batteries are charged.
Completely agree with you. It is bizarre. Cost Savings should power the house load through the peak and when solar kicks on in the morning it should go to the house load first and then to recharging the Powerwalls before sending anything to the grid. This maximizes export credits and minimizes imports.The main thing I don't like about Balanced is it will draw power from the Powerwalls during off-peak hours in the morning.

Why? My batteries are charged 100% by noon, so solar is used by the house, and the left over gets send back to the grid. Batteries are in standby until 3pm when they do 100% of the house load and 100% of solar goes back to PGECompletely agree with you. It is bizarre.

I switch to Balanced when I get up at 6:30am and back to Cost Saving at lunch everyday.
I have frequent power outages where I live, I've had 2 this month. They were short but one never knows. Any power taken from the powerwalls needs to be replaced later on so the net cost is the same as long as they get recharged to 100% before the peak rate change. The difference is the earlier they are recharged, the better prepared I am for a power outage.Why?

It sounds like were looking for the opposite. I want my powerwalls recharged ASAP which Cost Savings does but Balanced doesn't. The net cost is about the same for me since I expect a credit at True-Up but the earlier the powerwalls are recharged the more prepared I am for an outage.Completely agree with you. It is bizarre.

Mine pretty much do this but as I note up thread there are exceptions. If the algorithm does not think I am going to need the PW storage that day it will fill up to a certain point (not 100%) and then start using it for the house and spilling the remainder to the grid. This is the model for Cost Savings.I have frequent power outages where I live, I've had 2 this month. They were short but one never knows.

I've been using Cost Savings Mode every since I've had my Powerwalls installed except for a brief experiment with Balanced mode. My Powerwalls always prioritize recharging to 100% before peak rates if the solar power is available.Mine pretty much do this but as I note up thread there are exceptions.
