As I read through this thread, I found Gwgan's post 218 interesting. I an not sure what his buy and sell rates are. I think he is on net meeting and they are the same. If they are the same, maybe the system decides it doesn't care if it uses grid or solar. Anyone know about this?

I have 2 powerwalls with just under 10kW DC solar with the Tesla controller system. When the grid goes down, I don't see much impact on my home. Even the electric clocks hold their time. The only thing that seems to notice is my Dish Hopper DVR which does an automatic reboot. The system keeps...

I have used baby wipes for touch up work.

Based on the yellow microfiber cloth, it looks like he shops at Costco.

I don't have an X, but I am considering one. I have two cars (Chevrolet and Lincoln) with ventilated seats. This is a must for me in Tucson, AZ when the temp is 115. My black seats are OK with the ventilated option. Can someone comment on the X seats to their quick cooling capability -...

RKCRLR, I am using TBC. I have a 4 cents offset during peak and my system uses PW during peak. I actually have 4 time periods. In the summer, it is one peak, two shoulder and one super off peak. System has ran correctly for several years. In the winter it is even messier as we have 2 peak...

I find when I turn on the eye to show all activity, it is difficult to see the individual elements. I prefer the eye off and to only look at one element at a time. Then the graph seems to track what is happening.

For AZ there is not any real ROI for PWs. The peak to non-peak rates are to close. Not like parts of CA where the differ by up to 30 cents per kWh. In Tucson, the delta is only about 3 cents per kWh. The ROI I get is not having AC shut off, clocks to reset, etc. during a power failure. We...

I can't answer your question but ... Do you really need to have two high current EVSEs running at the same time. If not, you can get a two headed, power sharing EVSE and save a lot of money and work. I posted a link to the tesla solution below. There are similar units from other manufacturers...

Very interesting. Please share your ideas on why PW 1 & 3 run about 3 degrees hotter. Are they in a 2 x 2 stack?

I have 10 kW of solar and 2 PWs. My peak times are almost the same as yours, Jeremy. During the summer in Tucson, AZ I use almost no grid power during the peak (3-7 pm). Solar and the batteries take care of me. I considered putting in a 3rd PW for extra backup in case of a power failure but...

I like it because it is easier to get all the data - more like the original app which I refused to update until forced by Tesla.

In addition to the gateway, I have a generation panel. It has 4 breaker positions for up to 4 batteries. Currently I have 2 PWs and there are 2 20 amp breakers - one for each PW. To expand I would need a new breaker, wiring and programming of the gateway. In 2021 I got a quote for...

daniel, I have searched for a AC with soft start and could not find one. Only add on soft start devices. What brand of AC has soft start?

If you want to charge only from solar now, you can do it using the Emporia EVSE with their power monitoring system. Links to both are below. The EVSE is not Tesla, so you would need a tap to use it. I think a Tesla version will be available soon. A friend of mine has this with solar and 1...

I have solved a related problem that may be of help to you. I had my whole house, including my EVSE, on battery backup - 2 PWs. Later I decided to not want my EVSE to drain the PWs. My installer put in a normally open relay powered by the grid in the feed line for the EVSE. When the grid is...

I have a solaredge inverter. It always shows more than the Tesla app. Typically Tesla is 95% of solar edge. My installer thought it might be due to the fact Tesla only monitors one leg of my 10kW system but solaredge does both feeds. I also have 2 PWs but they feed the whole house.

Check to see if you AC can do a soft start. If not, then your AC should be separated from the backup. I have 2 PWs and soft start so my AC is on backup. However, I have removed my EV EVSE (Charger) from the backup system.

Three years ago, I put in solar with a great local company and it included a 2 PW install. Check in your area for local solar installer. BUT be sure to check their references. Another good source may be you Tesla owners group. Many BEV owners have solar and are willing to share their...

Note the "off grid" in what you quoted. Shutting off the power to the grid during a grid down condition is a safety issue.

I am not sure you need to replace your Fronius string with Tesla. I have 3 year old system with 2 PWs, a standard Tesla gateway, etc. But my inverter (not string) is Solaredge. The PWs take the same 240v AC via an AC to DC inverter that powers the house. You should be able to add PWs with...

tij644 is on the right track. You will get about 88% of the power you send to the power walls back to run the house. So you only need to consider the 12% loss. (This is based on my 2 PW system). I think some of you usage numbers are off. (Going from memory as you spreadsheet is on a...

I have firmware versinon 21.35.3 with Android and no second peak available yet. But the app version is 4.1.1-667.

jjrandorin, I have the same situation. Waiting for Tesla. But we are now in a dual peak season.

It may be the gateway version. I found it in the app under settings. Below it is shown my serial number for the gateway. It updated to this when I downloaded the new version of the app. Where can I find the app version? Thanks in advance for any help you can give me.

I just checked the Play Store for the Android version and it is 21.35.0 - the same one I installed about 3 days ago. I has the add a rate schedule button but it is grayed out. Is the version 4.2.0 a Apple or California only version?

holeydonut has the right answer. I put in powerwalls for medical reasons. However now PWs are ovef 6 months for delivery, so look to another manufacturer.

I am in Tucson and have the two split peak rate problem. I have downloaded the latest version for Android – ver. 21.35.0. It shows that it allows you to “Add New Rate Period.” However the button does not work. I have been trying for about 3 days. I have been using the custom rate plan with my...

Yes I have the same problem. No fix from Tesla. I have request a fix for over one year. Please also request a fix. Maybe if enough people report the problem they will act. Right now we have 2 peak times - 6 am to 9 am and 6 pm to 9 pm. I have set my peak as 6 am to 9 pm and it does a good...

My SolarEdge inverter also needs an internet link. So I have a swith for it and the GW. Your inverter may or may not need internet to do reporting.

If your solaredge is set up correctly, you should be able to click on the Layout tab and see each panel and its production. Below is a screen grab of my system. The panels are shown in their location. At least you would know when to call Tesla and wait on hold.

I suggest you use the Power Wall down to what reserve you feel comfortable with in case of a power failure. Your export is $0.03 correct? Your cost avoidance is $0.17 reduced by your battery efficiency. So at 85% efficiency (about what I also see) you net avoidance is about $0.145 per kWh. That...

I have 2 PWs and the AC compressor is backed up so the battery and/or PV system can operate in case of a grid failure. BUT I had to have a soft start device installed to reduce the AC starting current (LRA current) as it exceeds what the 2 PWs can provide. I understand that some AC compressor...

Insideevs has an article on charging a Tesla with a CCS station. Below is a chart from it. You can find it by searching for Tesla charging at a CCS station.

Very good summary. For Tesla names seem to not have to be fully accurate, i.e. FSD.

I have a spreadsheet that I use to record each days resuts. You can go back on the day view for some period of time - not sure how long. It's a real pain. Tesla should provide weekly, monthly and annual summaries, but ?????

Go to the Energy Usage Screen and activate all options - home, solar, battery and grid. See Left snippet below. Then scroll down to show the data - right snippet, the numbers next to the green battery shows the from and to powerwall. (If you can't find the Energy Usage screen, from the POWER...

Yes, most of mine are 5 minute outages. I understand the PW system will also go off the grid for voltage and/or frequency deviations.

I have mine in the garage. They are on a section of the floor that is about 2" higher than the area where I park the cars. I suggest you consider pouring a small pad that you can have them set on and be sure it is level. They still must be attached to the wall, but only to keep them from...

My local installer is now having to split the installation into two parts. Solar they can do in a reasonable time. The batteries they don't expect until November. Re your HOA, in AZ they are required by ARS to approve your solar. The Arizona Legislature passed ARS-33-439 in 1979 in order to...

There is a blue with B&W interior showing in stock in Phoenix, AZ.

I also turned off my storm watch. Red flag warnings are not a concern for me in our area. For the monsoon season, I will turn it back on.

There currently is a bill before the House, the Green Act, that has a provision for extending the tax credit. However, it specifically states it will not be retroactive. I doubt Biden would deviate from this as it was generated by his party. Link below. Has not moved since introduced...

Followed the link. Noticed it showed a 4% guestmate on passing.

There are two MY with 7 seats showing in the Phoenix, AZ inventory this morning. Go for them. Just checked and they are still there. They are demo units. The link below may work. https://www.tesla.com/inventory/new/my?arrangeby=plh&zip=85713&range=200

There are two MY with 7 seats showing in the Phoenix, AZ inventory this morning. Go for them.

This is a link to the current bill that contains the tax credit proposal. It is part of the Green Initiative. Has not moved since introduced. Looks like immigration or infrastructure will be the next big thing to occupy congress. I have heard nothing about pushing the Green Initiative...

Wow. I am used to only paying on the difference. I lived in CA for about 2 years, but I never purchased a car.

And the bill is still setting in the committee going nowhere.

Single or is there a divorce in your future. LOL
