Utility billing and VPP compensation are completely independent.

I looked at the source tweet and there was $20,000 for a service upgrade to 320A and an additional fee of $2,500 to handle the permit for the service upgrade. I think the customer would have accepted the quote without those two items. I would be interested to see the single line drawing and...

I don't have anything to contribute regarding the new scheme, but I did finally get a paper check from Tesla for 2023 VPP. I have two Powerwalls and never observed them discharging anything more than my household consumption. ie. never discharged battery to grid. The check was for $199.75. I...

It is a relatively straightforward change to the PCS to enable bi-directional AC charging. I don’t expect Tesla to support DC V2X at all. I also don’t expect Tesla to certify their solution with utilities to allow true V2G going into the grid. The current CyberTruck implementation is purely...

Left lane exit’s just aren’t that common in Northern California

If you don't own the charger, I doubt there's anything you can do about it.

I will say it again, Coal Capacity is not the same thing as Coal Consumption or Coal Emissions. I am not saying that China is doing everything that they should, but we need to be clear about what the presented figures actually mean.

This is my ideal Charge On Solar: This is the non-ideal case. I had to turn down the car charging to allow the PWs to charge. My wife ended up taking the car out anyway, so I could have just let it charge the car first, then charge the PWs after the car was unplugged.

I don't know if the schedule is a necessary condition, but I do have a Charge Start timer set for 12:15am on our Model 3. Charge on Solar always worked for me. The only thing that is not ideal sometimes is the car charging before the Powerwalls. I would prefer that the car never charge until the...

For many years, China has been planning to add many GW of solar and wind and at the same time add coal "capacity" so that there is never a chance of intermittent generating shortfall causing rolling blackouts. The intent is to grow the allowable peak demand, thereby allowing the economy to grow...

I don't actually have one, but did you check the DIP switches inside. I thought the older ones, at least in Europe, had a compatibility mode switch that may or may not have been documented. You could try that and see if it helps your situation.

For most people, there is no good reason to use PW3 without solar if you can get a PW2. The only good reason I can think of is if you need to start big motor loads and don't need as much energy capacity. I suppose technically, if you don't add any solar, they can't kick you out of NEM 2.

Los Altos - Loucks Ave has been sitting longer. Supercharge.info says Loucks is 428 days and this one is 377 Days.

I saw lots of people posting their solar production charts online that were near the path of totality. California was only about 30% occluded, so the effect was less. Here is my solar production chart from Silicon Valley. The effect on the California grid was similar. The interesting thing...

I would suggest that you should have high powered chargers in a section of the parking where you have to move your car, like visitor parking. The 6kW chargers should go in assigned parking stalls or long dwell where people are expecting to leave the car overnight or all day long. In fact, I...

No, it's just two chargers operating in parallel pushing current into the same (+) and (-) terminals on the high voltage battery.

You should be more selective about your use of the word "Free". Lots of stations are never free but always available. Conversely, stations that are always free are rarely available. Back to original topic. I think high power AC charging is a weird in-between use case that is hard to justify. I...

I have never heard of turning the car on and off before. However, it is common to need to plug the NACS adapter into the Wall Connector cable first, wait like 30 seconds, then plug it into the car. It also depends on which NACS adapter you're using. Some work better than others.

I could tell that was the situation from the picture. I stand by my assertion that it would be possible to put them there. Same idea as what I suggested earlier - pour a footing to support a concrete stub wall to support the Powerwalls. In this case, you would also want to put a retaining wall...

Even though it is a long length of wire, the space under the deck could also possibly be used. It appears to have enough height and would conceal the installation.

Would the HOA approve a metal shed? Install the structure that I mentioned above and plop a prefab shed over it.

Technically, the Powerwalls don’t have to be attached to your existing structure. You could pour a concrete slab to support a concrete stub wall just taller than the Powerwalls and mount all 4, two on one side and two on the back side of the concrete wall. Short underground conduit tun to the...

Definitely, the Gen3 Wall Connector would be able to charge your Roadster if it was commissioned as a home unit without billing. Once they turn on billing, you must have a S/3/X/Y car in order to charge because it depends on the car communicating with the Tesla cloud to authorize and handle billing.

Immediately before the 2018 Model 3, we had a 2015 e-Golf on lease. I also bought a 2012 Toyota RAV4 EV new in 2013 that is still my daily driver. My daughter can get her license in 11 months, so I have about that much time to decide if I will buy a Model Y or some other EV. I haven't even...

I only have to do that when my UPS is dead and my Ethernet switch is down. After struggling with the terrible Tesla WiFi losing connection with my WLAN, I ran an Ethernet to the Gateway and have been completely trouble free since then. Well, at least after I told the Tesla app to forget my WiFi.

Can you give a Plugshare link to the chargers you're trying to use? I am having a hard time getting it clear in my head exactly what equipment is being used and who is normally able to use it. If only modern Tesla vehicles are able to use it and there is no app based authorization for non-Tesla...

Yes. This is what I get when I put in the web address and sign in with the last 5 digits of the serial number:

This is only needed for specific functions like "Go Off Grid".

If your system is new, all the solar could be going to charging up the powerwalls while your home usage is still coming from PG&E. You should familiarize yourself with the app so that you know how to interpret the solar production, home consumption, and Powerwall energy flows...

If you go to pick up a new Model 3 and the screen says "CCS Not Supported", I would ask for a "Due Bill" before taking delivery. That means that they have to provide it at no charge, even if they do it later. Originally, CCS compatibility was not an advertised feature. Now, it is well known...

I think the OP was only considering conventional NEC load calc considerations. PCS can overcome that easily even in situations where nuisance trips would be rare even without the PCS.

If it's part of a Power Control System, it could be done. The UWC can communicate with a remote Neurio to reduce its load when the upstream feeder nears its limit. However, I don't know how and whether it can be applied to your specific situation.

The way the original NEM tariffs are written, as I read it, any interconnected generation may be repaired or replaced or expanded as long as the total CEC-AC rating is no more than 10% or 1.0kW greater than the originally interconnected equipment. I see no wiggle room for this controlled export...

I am skeptical that the IOUs will ever let go of the original terms of NEM disqualification. The export limits and accompanying hardware is definitely needed in order to allow greater solar neighborhood penetration, but my skeptical side doesn't think that the utilities will allow this as a...

Assuming the PW3 "expansion battery" is actually available, I would think that two PW3 and each having an expansion battery would be appropriate for your situation.

Example: Eaton 100 Amp 120/240-Volt 24,000-Watt Non-Fused General-Duty Double-Throw Safety Switch DT223URH-N - The Home Depot

The proper device for this function is a “double throw safety switch”. The lever has three positions: A / Off / B. You can wire it to supply one power source to one of two loads or you can wire it to power one load from one of two power sources. Last time I checked, the 240V 30A ones were very...

The hire car companies should be providing a charge roaming RFID card that will bill the renter for all usage during the term of their rental.

Look into load management. There is an accessory device for the Universal Wall Connector that measures the upstream current and can modulate the Wall Connector to remain within the upstream limits. If you have loads on the sub-panel that are only used intermittently, you might be able to put a...

If you don't want anyone to use the WiFi (including yourself), unscrew the antenna cable from the Gateway computer. That would greatly reduce the chance of anyone accessing it. They would have to walk up next to the box to get enough signal.

Generally Powerwall 3 is only installed with solar. Adding a meaningful amount of solar (1.0 kW CEC rating) will kick you out of your existing NEM agreement.

Everything I have read says adding batteries to an existing solar system will not change your NEM status. That includes after NEM 3 (Net Billing Tariff) started.

The placement of the pedestal bases only makes sense if these are V4.

Exactly. The inverter sizing in the PW3 makes a whole lot more sense once you understand that it supports battery expansion connected to that inverter. At first glance the Power to Energy ratio seems off.

There are several problems with this diagram. The Gateway disconnect is not shown. All AC (Wall connector, solar inverter, backup loads) should be shown connected to the Backup Panel. The sizing of the solar inverter is limiting the combined output of A) Solar B) Batteries C) Vehicle DC...

Powerwall 3 is a new product. It's way too early to be thinking about waiting for the next one.

They don't have to switch in unison. The PowerShare Gateway is only going to operate when the vehicle is present anyway. So, the criteria for each one to switch must be independent. That is another reason that they should be parallel and not series. Ford Backup Power Pro (or whatever they...

Scavenging heat from the drain water of sinks, showers and tubs would have meaningful heat recovery. However, you would have to plumb the whole house from the start with this in mind.

My existing main panel houses a CL320 meter. It has one 200A Main Breaker installed feeding the integrated breaker bus. A 125A two pole breaker feeds my Powerwall Gateway. If I wanted to back up some of the other loads in my main panel that are not backed up, I could move those loads to a...

If it's a grid down situation, it's better to put the energy in a car than to just curtail it, which is what happens when Powerwall batteries get full when the grid is down. If the grid is up, you can choose whether to just use surplus solar or charge with solar and a minimum amperage to ensure...
