As with the Windows version, I had to uninstall before the next version would be offered. This procedure has been a new experience. Thanks for the guidance.

I'm getting the same errors as above. On Android, I'm getting the NaN and in the settings I can select Extra Info, Powerwall battery health, after which no additional info is requested for a connection. In the Windows version I get the error that was seen in the screenshot above. The IP number...

Just for a comparison... I have a small system with eight panels about twenty-five feet up on the roof. It looks like about a foot and a half of snow on them. In the previous six days: two days of three watt hours, two days of eight watt hours, and two days not enough current to light up the...

From system status: 10584 nominal full pack energy. About four years from installation. The battery did sit for thirteen months after the manufacture date, if that makes any difference. I've been keeping track for about a year and a half and it hasn't changed much. It's a small system like...

It's really hard to put a price on a good installer. Your instinct about the better choice says a lot.

This is what MISO was showing on their operations pod.

In my case, the electrical code. The neighbor told me her insurance company had been snooping to find things that were askew. Our building permits for solar aren't showing up in the online records yet. My plan is to keep my head down and hope for the best. David

In Iowa, my installer wouldn't proceed with the installation until my insurance company gave the okay. Way back in 2019. I don't think they are looking for reasons to cut customer risk over here. However, my current Powerwall basement installation would no longer be allowed. David

Usually, someone who knows stuff chimes in by now. a) I am not that guy. b) Have you tried switching to self-powered mode for a week to see how that works? David

In the app under Settings > Powerwall you might have an option of Grid Charging. If so, toggle that to Yes. Then raising the reserve level should induce behavior similar to Storm Watch. EDIT: Tomorrow, my location is under "slight" risk of severe thunderstorms. I would wager there is no power...

Yup. The Storm Watch algorithm looks for a National Weather Service warning at your location. Even if you are a only few hundred feet outside of the warning polygon, you will not get the charging from the grid. Last week I had that very thing happen. A few minutes after the storm went through...

New Android version seems to have been released. I can see it now - I'm going to have to read the instructions. David

While using charge from grid this evening, Powerwall is pulling 1.9 kW instead of the normal 1.7 kW. First use since this firmware version. David

Yup. Mine is at 10571, also just over three years from installation. When I first started recording this a couple of years ago it was 11327. I kind of wondered if I could run it up and down 100% to 10% a few times, if it would recalibrate. Anyway, I mainly wondered about the occasional boost...

Here's a thing that has happened every so often after I toggled on grid charging. It seems as though the charge level sags below the set reserve. The gateway calls for grid charging for a few minutes, just enough to restore the percentage to the reserve. Is this telling me something about the...

Materiality is a concept or convention within auditing and accounting relating to the importance/significance of an amount, transaction, or discrepancy. - from Wikipedia In my case, I have a tiny system. As a retiree, my income is so low that it took three years to write off the credit. The...

Hmm. My installation has a CT clamp on each phase from the solar. Overnight, it almost never reads exactly zero. I think because of the way it's positioned in the service panel. If you post a picture of it, one of the experts on here might have a guess about whether it's being influenced by...

Did the requisite maths, adding in my average daily solar production, and dividing by my average daily consumption. (November 1 - 7) Result: 1.4 days. Note: House heat is high efficiency natural gas with 4 zones. Also hot water. It's a leaky 108 year-old house, but natural gas here is about...

@h2ofun Despite all of the posts we have seen, neither does mine show any limits.

Question indirectly related to this thread - How can one estimate the Powerwall potential duration in a long outage? I have very reliable service from MidAmerican Energy here in town. Our longest recent outage was one and a half hours. Problem: there is no more 3G here and my internet fails...

@Redhill_qik By golly, I see what you mean. There does seem to be a correlation between Standard Time and lower solar output. Hmm...

I'm blaming daylight saving time for part of the problem. If it got dark earlier, the peak wouldn't be so bad. (j/k) (social media: run with it.)

My experience with charging from the grid is: All of the calculations are based on what 6 Powerwalls will do. If 6 Powerwalls will charge at a rate of 10 kW, then 4 will charge at a rate of 4/6 times 10. Or, 6 and 2/3. Sadly, I have only one, so 1 and 2/3. (Of course, Tesla rounds the number to...

An additional benefit is that the VPP is distributed. That is, the energy released is near the point of use. Not traveling through miles of distribution lines.

If anyone else can't log in to the old app version.... I carry four android phones (don't ask). On two of them I have the old version 3 of the app. For three days I was signed out by Tesla and unable to log in. Then finally being able to log in. It might be my bad eyesight, or maybe I'm just...

22.9.1 since overnight sometime. Can't see around blinders, so operational variance undetected.

I have APSystems microinverters and the ECU. What you can see in the Tesla app comes from CT clamps attached to the solar wiring. Mine are inside my breaker panel. The ECU has no connection or relationship to the Tesla product. My system functioned perfectly well without the ECU because my...

If they could make the pole out of transparent material, the light could shine through. I suppose the magnifying glass effect might be kind of bad. 🔥

I'm not in the Northeast, so perhaps I'm out of order here. Earlier this year we had a red flag warning, but no Storm Watch. I called in and asked them to pass the circumstance up the chain of command. About two hours later, it activated. There are flaws in the system beyond the zip code...

I'm out in Iowa, yet there are two Tesla certified installers within a couple hours of me. I went with one of them for my system. I would think in New Jersey there are more Tesla certified installers than only Tesla. Without knowing their particular agreements with the mother ship, call one up...

21.35.0 in Iowa overnight from 21.20.6. No noticeable change in behavior. For the last couple of months nominal full pack energy had been dwindling to 11152. Since the update it jumped to 11270. Wishful thinking - perhaps a full system restart would cause a recalibration.

Issue with Go Off Grid Function I describe what happened when I intentionally did just that. Not gonna make that mistake again.

This is with the android version 3.10.14. The new version is not yet available. However, the pairing/go off grid options have appeared. This morning I decided to try out the new function. Going off grid was seamless, since the Powerwall was already discharging. The documentation indicates that...

Tropical storm Henri. It's concerning that those folks in the path of the storm could face prolonged and widespread power outages. Sorry if this sounds like a kook thing to say, but computer algorithms from a big company operating behind the meter can kill you. (Based on two bad experiences I've...

21.20.2 --> 21.20.6 since yesterday sometime. In Iowa. No flukes or odd behavior noted.

20 months since commissioning one PW - nominal full pack energy 11273

On your last bullet point, but not the focus of this thread. I have APSystems microinverters. The spec sheet the installers gave me says they are supposed to kick off, dead, at 62.5 Hz. However, they apparently have a newer firmware. When I went off grid at 90%, but still charging on a sunny...

@sorka , My comment might sound facetious, but it's not. I kind of want to do what your original post was talking about. So. I have a very small solar array, I'm a low energy user, and I have one Powerwall. If I can corral a qualified installer to do it, I would like to stack a second PW in my...

@ChicagoSox How's the production today? Mine over in northeast Iowa is a tad lower today despite the sunny blue sky. There is a healthy stream of water vapor coming in from the Rockies. If you are in northern Illinois, you might have noticed a slight reduction.

@coney27 Tomorrow will be warm and sunny. Get that Powerwall into backup mode. Sunday will be warm and cloudy, good bye snow. Then set your reserve high enough so you don't get backed in a corner again. I'll write to my Congresswoman and tell her to get the law changed. :wink:

I have 1:1 net metering here in Iowa. However, since this is my first year with one Powerwall and a tiny solar array, I want to know how I use energy and how the Tesla system works. Except for impending bad weather, I've stuck with self-powered mode. As a small example of the cost of doing this...

@CSFTN In my neighborhood up here in Iowa, any homes replacing a natural gas furnace use at least a moderately efficient unit. These appliances have a closed system that draws combustion air in and exhausts out through PVC pipes at the side of the home. In casual observation I have seen one home...

My external conduit goes up and over the roof, loops around the gutter, and down the side. The house is 116 years old, previous owners have boxed things in all over the place. There is no break in the external wall/soffit to pop back out of an attic run. The designer completely ignored all of...

Stormwatch has not lived up to my expectations. I've had three thunderstorm warnings for my location since commissioning. On the first, it was activated after the storm went through. Warnings two and three simultaneously overlapped my specific location. Nothing. I can see where they might not...

zappi - smart EV charger - made in Britain | myenergi The Zappi is mostly off-topic for this conversation, but charging from excess solar isn't really new. And the video has some peppy background music. (Okay, carry on.)

Yuh. I thought of that a little late. I have a small system from two months ago. Never been above 90 percent. David

My microinverters are supposed to ride through 61 Hz for 300 seconds. And 62 Hz for 15 milliseconds. So here's my suggestion that's most likely easier said than done: At battery state of charge 96%, raise the system frequency to 61 Hz. At 97%, raise it to 62%. 98% - 63%. 99% - 64%. 100% - 65...

I know for a fact the Storm Watch system is not intelligent. Last month Storm Watch was activated for a National Weather Service Winter Storm Warning. The next day, a separate weather advisory was issued, not including any potential for power loss. However, an error was made on the Weather...

My single floor-mount Powerwall is recently installed. I've wondered this same thing about the money and capacity. The fellow who did the battery install encouraged me to add another saying all it takes is the Powerwall and a stacking kit. I didn't think to ask about additional permitting. I...

New user here. A new set of 8 panels up on the second story here in northeast Iowa. One Powerwall in the basement initialized in December. The basement temperature is set to range from 57 to 59 degrees. The panels are in pairs, each pair with its own microinverter. Two pair are completely...
