I wonder if this is true for both DC and AC connections. I understand that AC doesn't have bi-directionality except the Cybertruck. I understand that CCS charging standard does have bi-directional charging as part of the standard so maybe there is access through the charge port, just not from...

Today I tested the nag frequency in my morning commute. It seems that when within 5 of the speed limit, the nags are approximately once per 45-60 seconds. This seems to decrease in time such that when I went 30 seconds between nags when going 85 in a 65 zone. Where there had been many nags...

My experience with nags is that if I am looking straight at the road there are rarely nags, like one nag in 3 minutes depending on speed with relation to the posted limit. As I tap the accelerator to increase speed, or the traffic is speeding such that FSD also speeds the nags are more...

If I was interested in a toy I'd buy a new GPU or a new console game. I drive 4k miles per month and having FSD has made this last month that much easier of a drive. Between selling TSLA stocks, buying 4 rental properties and turning one of them over this month, my budget is stretched. This is...

I bought EAP for $6k and thought after 2 weeks that it would be worth $6k to upgrade to full autopilot. The 12.3.4 is so good I am loving it. Now it has been reduced to $2k my only question is how long will this last, as I am certainly buying it but not sure if I can do that right now with...

From your response you tried it before the current version as your description does not match the current product. Now you get just the option of Chill/normal/aggressive driving styles and follow distance and acceleration and lane changes are all rolled into that. You should try it again, it is...

If you are under the NBT, AKA NEM 3.0 then my advice above is maybe not relevant. I don't know much about the NBT. The reason Self powered costs more is that it will draw from the grid the FEWEST NUMBER of kWh that can be drawn, regardless that a kWh might cost 2-3X more during peak times. EDIT...

The way I explain Time of use compared with self powered is this: If you bought batteries primarily because you like money more than grid morality then use Time of use. THis will attempt to maximize financial return. If you like the morality of a green grid more than money, then use Self...

I can't say whether this construction is bad enough to warranty a rejection but I do know a SE firm in Laguna Niguel who will certainly charge less than your quote. Our typical cost to engineer a set of drawings from them is much less than what you quoted. If you want a referral, PM me...

I suspect there is a smoothing algorithm that understands that there are likely 6 good production hours in a day, but if you have enough PV to fill the batteries in 2-3 hours, then there is no need to charge at full speed. Imagine that the PW charged at max in the above example. All else being...

Because you do not have permission to export power to the grid. Therefore you can only produce what you will use for loads or ESS charging.

Look into a heat detector as most smoke alarms cannot be installed in a garage per their listing. The smoke of combustion may trip then inappropriately, and most smoke alarms are not designed for hot and cold unconditioned spaces. Look into Omni Shield wireless heat detectors or Residio ProSIX...

Buyer beware is my response. That Voc appears to be edited through Adobe PDF editor. See the name of the product. For instance see the list of accredited test labs that can certify a product to 9540. Intertek does not have OSHA accreditation for UL 9540 as a test lab...

I took a look at the RUIXU site as this price seemed pretty crazy low. Unfortunately, this battery is not code compliant with residential installations on buildings in most jurisdictions. UL 9540 listing is required by both NFPA 855, IRC and the IFC. I see they are UL 9540 pending, but I am very...

I touch the accelerator very very carefully. Unlike many ICE vehicles, Tesla EV have a very linear power delivery with respect to pedal position. Many ICE vehicles are tuned to "feel powerful" by making the first 10-20% of pedal travel provide 50% or more of the available horsepower.

Good to see that others are looking at the available options to see what changes happened. I agree these can be confusing but I think overall this is progress. @KelvinMace does this fix your issue with TACC?

The reserve is the number it will use as a stopping point so that below this number the PW will not intentionally discharge to offset your loads. However it will still consume normal power to keep itself healthy and warm. If you are in a storm and there isnt PV to recharge things it seems...

To be clear I marked this disagree because it has somewhat incorrect information. Though the wire is rated for 90C you cannot use it to terminate in a panelboard at that ampacity unless the terminations are rated for 90C. No residential 240V panelboard and breakers are rated more than 75C...

Sure and in this case it seemed that the system was performing safely but not generating as much as it was supposed to be, so there was some financial loss. If that financial loss is larger than what you saved by going with Tesla then I would also be upset. If you accept that the total price...

NEC gives an allowance if 10% of your run length and no more than 10' is at a lower ampacity, that portion of the run with the lower ampacity due to temperature or fill limitations can be ignored. 334.80 Ampacity Amendment Type NM, and NMC cables shall have conductors rated at 90°C (194°F)...

I am not an MA electrician, but my understanding is that MA does not have a blanket restriction to use NM cable at 60C ampacity ratings. They are allowed to understand if NM is embedded in insulation for a good portion of its length, then it is rated at 60C and 55A. If there is no insulation to...

Glad it was resolved eventually. I imagine that as the low-cost leader they will not be immediately responsive to these types of issues.

I think but am not sure that if you leave it connected to 240v, it will eventually trickle charge itself from line voltage if it is still alive. I am not sure of this or how long it would take, but I have seen this trickle charge behavior when the breaker is connected but the switch is off.

Or utilities accept that the Inverter is an electronic device, that can limit it's own output. The reason they do so is likely primarily that they dont have to, and making it more difficult to get PV+ESS means they keep more customers reliant on them. Utilities are basically monopolies in many...

Sounds like you are doing what you can on this. It might make sense to talk to a 3rd party installer in your area as they are often better trained and more willing to be flexible where Tesla isn't and won't.

What size is your service? I cannot speak to "max inverter size your utility allows" but this might be an interesting question directly to the local utility to confirm what you are being told.

PW3 with Backup Gateway is compatible with 3rd party solar.

This sounds like the system is working as intended. There may be a slight grid draw at times. PG&E will push you into the NBT Net Billing Tarrif aka NEM 3.0. Time based control will attempt to use your ess to reduce your bill. I can't speak more specifically about how the NBT version of TBC...

I am concerned that your project advisor cannot determine if you have whole home backup. If I am giving them lots of credit, maybe they are new at their job. See my response in the other thread where you posted an almost identical question.

If you have the Backup Switch, then everything connected to that panel (likely the whole house) will be backed up. Unless you have multiple meters feeding your location, this means you have whole home backup.

If you have your plans can you attach them or take a picture of them? Interested to know the version of MCI.

If it looks like there is an exposed pin in your charge port, the insulator has broken off your car. The charge port will need to be replaced but I am unsure why you would have lower charging in the meantime.

Staying between the lines is the most basic of successes. The most objectionable issues camp up when going around a sharp turn, typically labeled 40 mph advisory. The old behavior was to slow down for the turn but to do it much too late and too large of a speed delta in just a second. It was...

I tried this over the last few days and am extremely impressed. I fully feel that my last experience with FSDb about a year ago was like a driver with their learners permit (at best.) Now I think my car has improved to the point of a new driver who just got their license. Almost all of the...

Day 3 with Supervised FSD has been great. I left it on all day for a drive up to the disc golf course and home, and it was flawless through the whole experience. Wife even thought it was worth $6k, but I am waiting a coup,e of weeks before deciding to upgrade from EAP to FSD. This morning I...

I took my first day drive in FSD 12.3.2.1 and have been pretty impressed. I am not quite ready to throw money at it but I am pretty close. I asked my co-worker who doesnt use any fsd to give it a try in their Tesla and will see what their response is. From the perspective of someone who bought...

Backup reserve is the percentage of the battery reserved for backup events. It will never be otherwise used to consume for other financial reasons If you like money more, then go with time based control. If you dont like money as much as you like the warm fuzzy of using as few kWh as possible...

It's more like controlled and uncontrolled inverters that never export more than the original system in a given period depending on how the metering goes. In NGOM are used then it will reconcile every 15 minutes. If PCS control is used then I think it's 2 minutes. If you just add a couple of...

I believe the spec means that 5 kW can be sent to the battery at any one time. From what I understand it can send 11.5 kW to the grid while sending 5 kW to the battery. I have not measured this myself to confirm.

PTO is the point when the PV may backfeed to the grid at any time. Before PTO, the PV is curtailed so that it doesnt leave the PV and ESS system. It could be that the algo for Cos and for pre-PTO don't play nice together for some reason. Not really sure, as I do not use CoS.

The Powerwall is a PCS capable device so it can be programmed to limit it's backfeed to a given panel, as soon as the future metering hardware options support that. I haven't heard of full vs partial powerwall 3 yet but this makes sense to not include the inverter if there is no need for AC power.

Right now, this is what I understand can be installed now. If installing multiple PW3, each gets their own 60A breaker, and each gets a split of the PV system connected to it. We are fully onboarded with PW3 now and have started selling and installing this solution. If another installer has...

While this was true, there is significant movement and utility agreement towards a couple of flavors of NEM expansion that are larger than what you describe. Basically, it will be possible to add a PV or PV+ESS system that never exports to the grid more than the original NEM 2.0 system was...

So far I know almost nothing about the expansion batteries, except that they aren't released to the 3rd party installers at this time.

No, you have calculated the ratio for a single Powerwall 3. It looks like you are quoted 4 of them. Each of them likely will have a portion of the solar connected to them, unless there is some interconnection restriction with your utility. See above, there will not likely be clipping because...

Tiny picture there but it seems to be a significant missing chunk. I would probably replace it unless the depth is very shallow like 1/8"or less

You are correct that this will become a limitation for some modules. Even if you do jumper strings, this doesn't fix the issue at the MCI itself.

Totally true and the intended function is the breaker trips before the wire overloads. The difference being with the extra 800w injected into the circuit, the breaker might not trip, since it isn't significantly overloaded, only the wire is overloaded. With just 2 heaters and no generation...

If your car charger was installed before the backup gateway, then the Tesla system cannot monitor it unless some CT's are added at the initial installation. If that car charger didn't exist at the time there is no reason to think Tesla would have added the needed CT's. Likely someone needs to...

I agree that practically it won't likely be a problem. If the 800W is injected between the breaker and the 2 loads then the load on the wiring will be slightly worse. The 2 loads together want 24A and the breaker will supply 16A, while the PV supplies the other 8A. Whether or not the breaker...
