No, single story house. A good portion of the solar panels with be over the garage roof, in fact.

Those are the alarms you can activate (in an interconnected manner) from the "output side" of this relay. The "input side" would be connected to some "external" switched circuit, such as one wired through a mechanical heat detector. Don't confuse the heat alarms that Kidde happens to make...

I believe the listed alarms (smoke, heat, or otherwise) are simply all those Kidde models which are compatible with the 9V interconnect signal that this relay emits. But, none of those alarms "need" to use this relay. The need for this relay arises in situation where some "external" 120V...

I am not alarm expert either, but in the alarm world, and in the context of this manual, I believe "supervision" means configuring alarms/detectors/etc. such that a wiring fault (disconnected alarm, etc.) can be detected by the alarm control panel. As I understand it, supervision usually...

Fwiw, I was going to (any may still if I can find an installer who is okay with putting batteries in the garage). I checked this exact relay solution with my building dept (as they had said they would require a particular 194-degree mechanical heat detector for the garage) and they said they...

That’s what I’m saying…. the text seems largely unchanged from the fire code. At a glance, it appears nearly identical. The garage diagram does differ a bit, but is very similar to the garage diagram in the fire code.

That doc just seems to be a restatement of the current fire code. It is something more?

Thanks. This might also explain the (apparent) cageyness of my advisor. I mean, how would it look insisting a customer must install right outside the kids’ bedroom window (my case) while at the same time explaining the garage is off-limits because of “the risk” (which he hasn’t said; I’m just...

@Vines, have you heard anything about Tesla recently "officially" starting to refuse interior PW installations in attached garages "throughout California"? See where I quote my Tesla advisor in my earlier comment. Apparently, interior installs in detached garages are still possible... though...

I appreciate and accept the moderation, though I think the possibility that Tesla has unilaterally disallowed attached garage installations might be worthy of its own thread. I was hoping to reach a wider audience than just the people who had read deep into this thread. Also my original post...

Right, but is the switch on the PW sufficient (now with this locking ability) as a disconnect per code?

So after a few weeks of back and forth with my Tesla advisor about my solar/PW install, which Tesla has designed for an exterior wall (I want it in the garage, which all seems okay with my local AHJ), the advisor suddenly says this: So, no attached garages anymore, according to this. And...

Yet they let you check off, "I would prefer a garage installation", when placing your order. 🤷‍♂️

Thanks for chiming in, @wwhitney. That was also my assumption. I understand electrical circuits, and diagrams like this seem pretty self-explanatory to me, but I am certainly no expert here, and so I wondered if that line had some special significance that I just wasn't familiar with. I know...

Yes, the combo panel is outside. The "service disconnect" you're referring to is the first "125A/2P" switch depicted in Tesla's diagram? Got it, makes sense. My house currently seems to have this breaker outside, in the combo panel, rather than inside with the distribution panel. The...

Just curious then, what are all the “line of sight” discussions about in forums like this? The discussions usually seem to be in regards to disconnect switches and batteries.

Thanks very much @Vines. Right, the main 125A breaker (right after the combo service panel) and the e-stop button, if both used, would completely de-energize all circuits in the building, and the PV modules. Follow-up question: What code does the other 125A breaker (depicted between the Tesla...

Ah, thanks. Well... my system does, in fact, meet those criteria. I will have a single array occupying one side of the large gable roof (which, luckily, is south facing, slightly south/east). There is no shading, not even from my own chimney. Still an issue? Btw, my design appears to have...

@Vines, if I can bother you for advice... Is there anything about Tesla's proposed whole-home backup design (above) that would require that it all be installed outside, instead of inside my garage? My local officials are fine with a garage install in theory, provided I have a heat detector...

Thanks for the reply. Wow, 8 PW. Thanks for the advice to keep pushing Tesla. What is the issue/advantage of avoiding a parallel run to the third inverter? And which run? DC run between panels and inverter, or AC run between inverter and gateway’s load center?

I am in San Mateo County, on the coast. I have already discussed my potential garage installation with the local city building official and fire official, at length. Based on what they know, they are fine with it. Interior side wall, 36” up, no bollards needed. All I am missing is a heat...

The meter and main service panel (with just the main breaker) are on the opposite side of the house from the garage. The garage has the distribution panel (with all the circuit breakers). I want the PW in the garage for protection (keep out of damp, salty coastal air) and to avoid...

I am in the Bay Area of Northern California, in PG&E territory. Tesla recently completed the site assessment for my solar + whole-home backup PW install and, despite my indicated preference for a garage installation, and prior discussions with my Tesla advisor about it, Tesla has provided a...

I agree with you, and apologies, I miswrote "module-level" instead of "unit-level". I meant to write, "Tesla claims the Powerwall 2 meets the 9450A unit-level test criteria (on their spec sheet)". I actually had a conference call with the city building official and a deputy fire marshal today...

Yeah, a deputy fire marshal for my jurisdiction says that stacking is not allowed and multiple Powerwalls cannot be closer than 3', though he does say that exceptions are possible "in theory" with UL 9450A documentation. Regarding Tesla, he says that, although Tesla claims the Powerwall 2 meets...

So the fire marshal and city are recommending the System Sensor 5602 (or 5622) and requiring an auxilary horn be installed within the home (audible from bedrooms). Looking at the System Sensor 5602, it seems to only have two connectors (I assume for 120V power, hot and neutral), so I'm not sure...

Thanks @Vines. HD6135FB appears to be a First Alert model number? I read somewhere online that officials like to see Kidde-branded models (even though they are identical). And, how exactly, does the heat alarm need to be interconnected? I've also seen the words "hard-wired" (which I take to...

I am in Half Moon Bay, which is in San Mateo county. I have spoken with a very nice deputy fire marshal with San Mateo County Fire (who was familiar battery installs, and performs inspections) but, turns out, only for unincorporated parts of Half Moon Bay. Where I live, within city limits...

Back in September 2021, member @Vines posted a comment, which said in part: Can anybody verify this? And, if so, does anybody where to obtain a copy of the test report? I have a pending solar + PW order with Tesla and have been speaking to my Tesla advisor, and have asked him the same. At...

Thanks for the thoughts Greg. I know it... I am thinking about getting 4 PW (total 54 kWh) and I am going for the maximum solar that I can, somewhere near 24 kW. I have a great roof for it too, all the panels would be in a single plane, on the southern facing portion of my roof, at a 19...

Thanks... and bummer. I assume a system like this would also be capable of powering the battery from solar? I assume there is some "right piece of equipment" out there than can intelligently charge the battery from excess solar and/or grid power (basically, select from some number of...

I am researching adding solar and battery storage to my home. Question: If I simply want to utilize only my own self-generated power, yet still be connected to the grid (basically, as a rarely-used "backup") will Tesla Solar install a system that is still connected to grid, but only to consume...

TL/DR: The new "Scheduled Departure" seems to have a bug where it slowly "micro-charges" your car, every two seconds, can wear out relays in your EVSE, and generally be annoying. More detail... I just tried out using the new "Scheduled Departure" feature and noticed that my EVSE (a...

Special character like what? Would an apostrophe be considered special, as in "Bob's Tesla"? I bet a lot of people name their car something like that.

Mmm, back in 1917, we had to walk uphill to the Supercharger... both ways... and we liked it!

Today I got my P100D (early 2017) back from the Burlingame, CA service center with the revised 77-C parts installed on the front wheels. They had the car for a week, also did an annual service, and worked on a couple other minor (unrelated) issues. I have been experiencing "the rattle" for the...

Yeah, neither do I. I just have "Home", "Account" and "Sign Out".

At the top of what page? When I log into tesla.com (in my browser) there is no "history" link to click. I've tried visiting the various account and car-related pages... I can't find any "history" link. I have used a supercharger twice with my Model 3 and have yet to seen evidence that I am...

Two issues with v9, versus v8 and previous versions, that I have noticed: * The map gets progressively less and less responsive (both the animation while driving and if moved around via touch) and the animation (while driving) more or more jerky. But, if you reboot, the map is instantly much...

This rattle occurs at low speeds (around 10 mph) and has nothing to do with lane markings.

I don't use either of the pronunciations in the survey. (And I don't know anybody who pronounces the "a" at the end as "er".) Personally, I pronounce it "tess-la". However, I think Elon Musk always pronounces it "tez-la".

Correct. You guys remember the story about the guy who drove his Tesla into the desert to go for a hike, "cleverly" taking only his phone? When he returned to his car, he couldn't get back in, as he was well out of cell range. He hadn't realized that phone app doesn't talk directly to the...

Anybody? ^^^^

On the Model S, are the side-window housings actually painted to match the car (e.g. have an actual base coat, then clear coat, etc.) or are they simply shiny plastic that happens to closely match the finish of the painted metal work?

So, I took my S to the SC last Tuesday. The MCU was replaced, without question, with the repair completed in 3 days (I had a couple other items worked on during the same visit). The invoice says, "Replaced the media control unit (MCU) and verified proper fitment and secure". The yellow ring...

My neighbor, who has seen my Tesla and talked about it with me before, at one point suggested I get a louder muffler, since the car is so quiet coming down the street. I wasn't sure if they were joking or not.

Well, now that I know the trick (holding the handle button), it actually works pretty well Usually, where I work, what happens is you ping the other person first saying, "Hey, is your car done? I can go out in a few minutes and swap the handle. I ping you when I am at your car". Then, you go...

I just noticed this "yellow ring" on my screen too. Car is 6 months old. No extreme exposure... always garaged home and work. Mine was built-to-order and then delivered February 2017. I guess I'm going to the SC.

I know what the colors means, I didn't understand the sequence (begin holding button, remote unlock, keeping holding button while pulling out). Tesla should put a note right in the app next to the "Unlock Charge Port" button, stating something like, "Other party must also be pressing and...

Okay, confirmed that this is the correct procedure with my own car and iPhone app in my hand and fob left far away (to simulate remote unlocking the charge port for myself). If you are NOT holding the button WHEN the remote unlock command arrives, the ring flashes white only briefly, then...
