How do you think the system tells the difference between loads on and loads off? To the PW system, there are just 3 points to measure, at the Solar, at the Main consumption CT's and at the Powerwalls. The system cannot tell the difference between you using power between the solar and home load...

This is very true, and also when there is plenty of work, why take on jobs with more risk if you don't have to. We have just modified our policy on this and will now add PV or ESS to an existing system that was not installed by our company within reason. We will add exclusions to these...

My understanding is this will happen every 3 months, to maintain the SOC accuracy with the Powerwall 3. The system will discharge to 20%, then hold it for about 2 hours.

Nice, same here in PG&E territory.

Here is what mine looks like. Looks like you are missing the slider that adjusts the reserve for VPP.

Ask them to check alignment, toe issues can easily cause a car to feel unstable, and some Teslas had bad alignment from the factory or maybe one of the delivery drivers hit a curb.

That is the menu where you can turn on and off the VPP, and also to set the reserve percentage of the VPP event. Also you can select the storm watch or VPP as the priority event.

Agreed, I see the 42 kW sustained then the reported spike in home usage. I was intending on reassurance compared with my initial email where I thought things were more serious.

This is your best solution really to have panel limits set so that you do not trip the main breaker. If your house went into sustained load such that the limit was exceeded, the limit is not set. Have your installer set panel limits so in the future the Powerwalls would stop charging to meet...

Have you had any VPP events this month?

This thread is about the Virtual Power Plant program, and those only happen when the grid is up. Not sure what you are trying to communicate here.

Usually it takes a significant electrical fault to trip the main breaker, so be careful. What size is the breaker? Have you had any recent construction or landscaping between the installation and now? I would have an electrician come to inspect your breaker panels for signs of arcing or damage...

It sounds like you want to specifically run ON GRID. To do that you want to turn off the breakers that feed your powerwall and solar inverters if any. The gateway may throw errors, but it will not be able to deploy any power. However the gateway hardware will still be connected, so this will...

I see the language as well that there is to be one event per month, and no more than 35 per year.

I also got in the DSGS with a very short wait just about a week. I did not hear about any events in May this year.

It appears to me that you have no solar configured, therefore none will be charging the batteries. You definitely need your installer to come back and complete this job.

Arguably, there should be an app so you don't have to lol. It would be the simplest possible thing to send a text when the local weather and production didn't align for 2-3 days. Bonus points for checking deeper at the string level voltages against some reference or microinverter checkin if they...

What is your current app screen showing during then solar production? What does your app show during the evening when the sun is down and you are living your best life (with lots of stuff on) What is the current state of charge of the ESS? Try flipping your main breaker or going off grid, does...

I personally love that there is no "dead zone" in my steering input. I can move the wheel maybe 4mm side to side maximum before the wheels start turning. Others might like being able to sneeze, and have no movement of the car, despite they just moved the wheel like an inch. My borrowed Truck is...

I am not 100% sure here but I think it's unlikely there is a dc/dc converter increasing the DC voltages inside the Tesla PV inverter. Maybe someone else with more hardware experience can speak to this. The Solar Edge optimizer does have a buck/boost converter in it, and it is around 99%...

AC coupling is only on hold for PW3 plus the Backup Switch. With the Gateway, AC coupling works now. These days with inverters like the PW3 have a silly wide range of DC voltages they will take. A string of 3 qcell modules will work and so will 13 of them so you have massive flexibility. As...

Who installed your system? This is who you are contracted with and who services your warranty. If your equipment fails, the installer works with the manufacturer to get that equipment replaced. It sounds like that happened. Sometimes a customer can submit warranty issues on their own, but...

If your installer gave you a production guarantee, you might be able to approach this from that perspective. Usually the winter months are the lowest production so you probably didn't loser out terribly for the year if it is working now. However it sounds like you had someone other than Tesla...

Typical measured values of our customer's 600-200A service are between 0.08 ohms and 0.22 ohms. The larger the transformer and closer it is the lower the impedance. I do know that the measured impedance is supposed to be a combination of resistance and reactance. Also, I think standard...

That's about 152A if it was all running full tilt boogie. Certainly there would be some losses from the DC to AC side. A typical 200A service would have wires inside it rated for 160A continuously, but who knows how large the line side conductors are. Regardless that's the power companies...

I have to start by mentioning that these types of grid issues are not my core competency, so I am guessing a lot. My first question was similar to Waynes above, and wondering if the PV inverter was actively exporting. You mentioned that you suspected impedance to be off, so I was thinking we...

Lots of interesting information about the new DSGS program and it will probably be better for almost everyone compared to ELRP program. A couple of points to note: For those with an export limit, you can charge an EV or use other loads to spike your demand past the export limit, and force the...

Cool what kind of car was that?

Though this is true, direct communication is better. How otherwise can you differentiate between a car in full brake lockup that is panic stopping but not actually stopping very quickly compared to the magnitude of the brake pressure. Also when just one brake light is showing you don't have the...

I had often thought a visual code transmitted by the blinking/refresh speed of LED taillights would be an awesome way to implement some simple wireless vehicle-to-vehicle communication. Even if that communication only contained the magnitude of the brake press, that would be useful...

I drove my Model 3 for 140k miles and repaired and filled 5 different rock chips, always before the damage spread. If you get the initial damage before too long you can often avoid replacement and only have a tiny distortion in the glass. With my Model Y I got a crack within the first 5k miles...

Since I found this so useful for my 1.5-2 hour daily commute I bought the upgrade from EAP to FSD for $2k. I wasnt overall satisfied with the previous FSD versions though they did some things well. I am very happy with the current tool and how it makes my drive easier. This version seems to do...

It could be that your installer used firmware to flip your CT's, and a gateway update changed this. Other than that, I do not know what might be happening

Currently Powerwall 3 is not compatible with Neurio meters, regardless of site controller and islanding hardware. Powerwall 3 with GW2 is compatible with wired CT's plugged into meter y with 100A max measurement.

If your PW3 is connected to a Tesla Gateway it should have the ability to use Meter Y (100A max) to capture the consumption of non backed up loads. This assumes there is a way to get wired CT's from the GW area to the wires that feed those loads, and have a place to plug in the GW2.

I am not sure about your local grid conditions, but here in California I work for a solar installer. We have never had any issues related to harmonics with any on grid systems. Most inverters are rated for a THD of less than 5% Off-grid systems that never see a grid and have to balance a...

It sounds like the CT's for something are not reading accurately. Call your installer out to fix it.

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...
