The reason why folks in the past had them moved easily is the codes had not caught up yet. Trying to move one inside today is different than in the past. In fact several of our jurisdictions are now requiring a separate fire department plan review and approval for any ESS inside. By comparison...

Good info Wayne, thanks.

Typically these connections are threaded. I am not sure that soldering is an option, but I do not think it is and if it is I haven't seen that. Copper is not compatible with Natural Gas services at all and NG will corrode copper. Sounds like you got the stickler rather than a typical inspector...

I cannot say that your kit shown will work but it probably will. There is proprietary software, but I think the hardware is universal.

Interior garage installations have significant other hurdles, besides just mounting on a different wall and bringing conduit. There are fire issues to consider and the fire codes are getting more strict. You may need a heat detector installed in your garage. You also may need bollards or wheel...

The Powerwall + can output 9.6 kW (40 A Continuous) when in off-grid mode. It is not clear to me whether it can do this purely on PV power but it might be interesting to know.

Hi Robert, in your situation I would recommend the y-splitter solution, assuming that your neurios are the newer versions. Older ones for a GW1 can also be split but the parts are sometimes hard to find. As to your other question, the car charger will talk with the TEG and you have the same...

The wall connector will work fine connected to 2 of 3 phases at a 208V service. This is how my gen 2 HPWC is configured at work. You will get a slightly lower charge rate compared with 240v. I assume the GEN 3 is the same, but am not sure.

Lol, I hope their electrical knowledge is better than their fire code knowledge.

Post a picture of your plans. A 100A breaker would be sized for a 20 kW inverter or so. If the breaker feeds the essential loads panel, then its not an inverter breaker. It may be labeled that way so the firefighters can turn it off without guessing.

That would be crazy large breaker, and most likely that breaker feeds a subpanel in the house somewhere. That other subpanel, probably near the inverter will have the inverter output breaker in it.

If the inverter is connected to a 40A breaker it will never output 10 kW of AC Power. It may accept 10 kW rating of DC panels or more, but the peak will not exceed the inverter output rating.

Theoretically the (13D?) fire suppression system you have currently should be enough to satisfy the city, but your installer should communicate that to the city. Oakland is really slow so the installer may be just punting this decision and going with an exterior solution, rather than trying to...

Maximum output is defined by how large your PV inverter is. If this is connected to a 7.6 kW inverter then that is all you would ever produce (at 240v) even with perfect irradiance on every plane. Likely the maximum you will get will happen in the afternoon as the sun is getting a pretty good...

Wow, interesting and welcome to TMC. I have yet to see one person trying to troubleshoot an off grid system by themselves, so things are a bit different. I do not think many people use Powerwalls for fully off-grid setups. Most off grid folks want a lot more control over their setup and go with...

How long have they been in the box? That is a pretty good price if the unit is still within its 1 year shelf life.

Congratulations! I am still waiting for approval for passing the peak demand check. Apparently, PGE cannot pull up our account information, so our approval is on hold at least for the last month.

Hopefully this was good enough for them, and you get back up soon.

From my understanding, Solar Edge requires the person reporting a down inverter to be in front of the inverter.

Unless this was your agreement initially I also consider it unacceptable to leave out the non backup loads from measurement. It just sounds like they don't really understand what the metering needs to do.

I am 6'5" and about 300 lbs. I fit in my model 3 just fine, though the seat pan is a bit more narrow than mine.

I can't speak from experience but I would like to think that the TEG has a wider range of voltage and frequency allowed in an off grid design. If the generator bogged down significantly, or went out of voltage range for some reason, I imagine the contactors in the TEG would open and battery...

Thanks, there should be half our company or more making it, we will have more than 40 showing up to stand up for our rights!

The Powerwalls would be better off at a lower discharge rate I think. I don't have anything to back this up, but it makes sense that driving anything significantly below its limit will make it last longer. Also it is a known feature of batteries that the slower you discharge them the more you...

The OP needs a system and I honestly recommend waiting or find another top-tier supplier. Really a home ESS is a big step and could go sideways if you choose cost over quality. Enphase is a quite good system but needs enphase inverters I think. OP, what is driving your need for ESS now?

The weather in Santa Cruz is nice for a beach house, you need a weekend pad right? We will be happy to do your 2nd house lol. You just have to make the kitty stop crying.

The funny part is that if the system was Off Grid, then Tesla could easily have the generator charge the Powerwalls. I think it is a moral decision not a technical one. Technically you could just tell the GW2 that it is off grid, and then use a 2 position transfer switch to change from grid...

Correct

I cant tell how much is malice and how much is just pure incompetence on PGE part. For instance, during PTO, they apparently changed the account name, erased the old account, but put in no new billing address or any other billing information. We literally got no bill for the last 4 months lol...

That clipping is insignificant, also your dc/ac ratio looks to be right in the sweet spot. You have a good design that is capturing a great area under the curve. Do not worry about this small amount of clipping. It will lessen over time and as the summer hearts up it will be even smaller.

I do not know the answer to this. Tesla might know, but since it is not code required I doubt it is implemented. We use a double shielded TC-ER wire in conduit for our ESS disconnect buttons. This wire could still be melted internally but it would take a lot more heat than a simple twisted...

Or it could be there is a known problem with computers losing the audio to the subwoofer and door speakers. Service is trying to make that your fault.

I would say your 12v is starting to go. If you got 3 years out of it you did pretty well IMHO. I replaced mine at 3 years as a preventative measure before I left on a road trip.

PM me if you are interested in some plastic letters or logos. My limitation is the object cannot be larger than about 12" tall with basic stock. I offer them in 1/8" thick plastic, with double side adhesive pre-applied. If I special order material I can do objects up to 17" tall and 23" wide...

That explains why I see it pointing north more often, and my North and west exposures are not as good as the south ones.

This is the device I also recommend.

The valley is a couple hundred feet deep, we see the full sun on the dish from 8 am to 4-5 pm at our house this time of year. Our area is waitlisted, and I knew that despite the coverage issues it's probably better than the current point-to-point solution. I only evaluated one possible location...

We live in the center of a 7 acre clearing, in a valley surrounded by trees. The area around us is clear except one tall tree for about 200' from my house, then the redwood fills the valley sides. Solar access according to a Suneye is better than 85%. Starlink app says I will see an obstruction...

Wow, it is really significant how much of the sky you need to be able to use this. I have pretty darn good access for a rural location and Starlink is complaining about partially obstructed sky. It is saying that my obstructions are causing regular satellite interruptions, and I'm not sure just...

Yes, that is the core of my concern. ESS is required to be shut down from the exterior of the home. Add a remote battery disconnect at the location of the rest of the service disconnects. This will take down the ESS, which will take down the PV as soon as the grid drops or the main breakers are...

It is Surfnet, a local provider of point to point internet beams.

Yes, I put too much stock in what I am used to seeing here in California and forget that in other places CSED aren't common.

I got my starlink RV kit yesterday and set it up on the roof. Already, my speeds are 10-20x faster download and similar upload speeds. I cant wait until I have a service address and therefore have some network priority.

I would charge 10 hryvnia per kWh just to be that way.

It means randos can see your 5 car charger mecca and come knocking or texting looking to bum some electrons. You know you want to!

It's just not what the text says just above it. Ok now this makes more sense.

Well, if there is no issue then no worries. If you start frying power supplies for computers and such then you know the source of the problem, it's the 65 hz pumping through your microgrid. Keep that old inverter in good health. If those are positive ground sunpower panels (likely) they...

It is a delta configuration, but different enough I thought I'd mention it since we were talking theory. I am also not an electrician...yet. I am working on it.

Regardless of where you land the 60A breaker, you will be able to charge from the grid. Depending on your TEG settings, your Tesla may or may not charge on battery backup mode.

My comments I have to say, I don't totally understand your system, or maybe I just need my coffee to kick in, since I slept in and am on vacation. I was up late at a concert last night. Around here, your 400A combo panel with meter would be located on an exterior wall, so the 2 main breakers...
