Out of curiosity, how close is that the the yellow energy label on your water heater? (Make/model?) All the best, BG

@Matt-FL Thanks for sharing the wind direction and speed data. People have done (small) studies with forced ventilation under solar panels. In every case that I have read or seen, the energy gain is much larger than the energy used in the cooling fans. It is one reason why ground mounts are...

Even a water heater in a conditioned space is significantly warmer than the area around it, and thus the water heater does have significant energy losses. I think that every water heater should have an extra insulation blanket on them. The blankets are cheap, installation is straightforward and...

To save more energy, I think that you will like a heat pump model, but I would ask how close the water heater is to sleeping spaces. They are noisier. You might want to double check the energy use on that dryer; is it a pure heat pump or a hybrid model? Whirlpools aren't terribly efficient...

Any given panel has a decrease in output per degree of temperature rise at the panel. Typically, it is in the range of about 0.5%/deg C. There is every reason to suspect that the panel temperature is not linear with respect to outside air temperature, and small changes of wind direction and...

Do you have a sense for how many kWh might be in your "excluded" green peak? (Per day? Per year?) I would look for a DC loads that you might be able to add; hot water heating elements (inexpensive), a programmable controller for other DC loads, e.g. DC AC unit(s), DC freezer fridge, or even a...

I do not see how @xrg458 can game this much if the inverter output is throttled. I think a little could be done by a fake utility rate would help, but as far as I know nothing short of CT monitors on the inverter and on the EV, with a variable EV charger would likely optimize the inverter output.

As the above proposal does not make mention of the existing fees, I can't tell. It quotes text from '205 requiring " It then goes on to quote a two dollar reduction in monthly fees for FAER consumers; Not sure whether "fixed charge" means MDC or something else.

For a little transparency on how the IOUs propose to track income; https://docs.cpuc.ca.gov/PublishedDocs/Efile/G000/M520/K530/520530748.PDF Basically, they intend to leverage the income information that they have for FARE customers into two tiers, and lump all other customers into the highest...

Well, if you keep the antenna cable, you would be able to use WiFi, if you need it.

You have taken some reasonable steps in my view. While it is not an unreasonable concern for some people, but given that someone would have to have access to something within WiFi range to pull it off, it does limit potential attacks to being near by. If this a serious concern, there are a...

Yes, that would be desirable, but Tesla doesn't have that AFAIK. I do think it is prudent to assume that devices will be hacked into, though not necessarily just from WiFi. Plan A would be to run a dedicated Ethernet cable to the Gateway. Once a link is established over the wired LAN, it is...

What is your desired goal here?

Consult your tax professional is as good as it gets. Whether any one did or didn't is not IRS sanctioned guidance and should not, at least in my opinion be relied upon.

We are close to the same situation, with lower demand, less solar, and same storage. Following your analyses elsewhere, I realized the importance of the MBC /NBC offset, and went from self powered, to time based control. I am still fiddling with charging times for the EV by manual starting the...

. Perhaps I should have called out in the original post that the vertical is percent of nominal voltage, I.e. 110 means 110 x 120 = 132V. Sorry for causing any confusion. The original post language, and details are still accurate. BG

Isn't your contractor dealing with this? How about bring the PV conduit in to the right to avoid the issue? In general the concern tends to arise around things like regulators that have the potential to vent gas near things that might serve as ignition points.

Again, guessing here, that type of parameter tends to get set somewhere in firmware because the upper limit is a function of the limits on the control hardware (Tesla) and (probably) design goals for minimizing the voltage to which the customer's equipment is subjected to (NEMA/CBMEA/ANSI). In...

I suspect that the Tesla firmware only records an out of bounds error. FWIW: if it were me, I would not design the circuit to stick around to actually try to measure the peak value as that would only invite damage to the monitoring circuit. It would be safer to get everything out of the way as...

I have to admit the several cyber trucks that I have seen around here have had numerous, shall we, say fit and finish deficiencies... Granted a few were pre-delivery units belonging to a favored few that turned up in the Bay Area early. Still, would you hand out units to "special" folks that had...

I'm not a tax official. Check with your tax preparer, and you can read the IRS publication, form 5695. Non-official guidance is in lots of places. Look for "IRS" "put into service" or "installed" and "solar". E.g. here All the best, BG

Well we only tried three... TBH, I don't know if it is one of those complex handshake process things wherein you have to add a dummy to the gateway, delete the old one from the gateway, then power up the new neurio (then configure it to a new IP address, already reserved on the router to prevent...

When my neurio was replaced two years ago, the installers said that the installers had no more version 1, and that Tesla was moving to V2 for a variety of reasons. At the time, I was told that a neurio was a use once and dispose of device that could not be reprogrammed to a different install...

You realize it is a rendering, right? It is a wall in front of a solid wall that is going to pass very little flow. This guy actually built one that didn't actually turn in a stiff breeze. Could you build one and have it turn? In my opinion, yes, you could. I think that the video above has a...

@Oz-X I hope that it works for you. It did for me 99.99% of the time. The Gateway needs to be configured for the new MAC address for the new neurio, and the new neurio will need to be put at an IP address reserved on your router. (The reserved IP address is vital.) If you reuse the old IP...

My gen 2 neurio does not stay on line reliably despite strong WiFi at the neurio, but it is enormously better than my prior gen 1 neurio. I will say that in my view neurios are very picky about being in the same 2.4GHz SSID with the TEG, as they connect via their MAC address. Also if your router...

Gosh, it seems as if MCE is asking for an up to 80% discharge 365 days a year for $120 to $240/yr. If MCE discharged daily, that would be less than $0.037/kWh, with all the wear and tear on the owner's equipment. Reminds me of Barnum & Bailey's door next to the "Egret" cage, labeled "Egress"...

Actually, it is net profit, so much more than just a 24% rise in salary. With all the violins playing for their supposedly hard times, one might have naively expected a loss.

I don't. I put in a ticket, but I'm not optimistic that will do anything. Perhaps if a bunch of us put in tickets it might get things moving. Given the current cash flow issues, I wonder. All the best, Peter

@zƬesla The flower turbines are certainly pretty; do you have pricing on them? I don't see them actually available on their shop page. A cluster of five large turbines is going to need at least 4.5mph 24x7, or five mediums would need a minimum of 8.5mph wind 24x7 to get 12kWh/day per their...

Perhaps your explanation of the cause sheds some light on the issue. Your first plot shows that L1 stayed up, (consistent with the crew's explanation) and you had some rapidly changing loads, which may have transiently exceeded the Powerwall's ability to frequency shift. IIRC, there is a limit...

@zƬesla Have you measured your windspeed? Optimally, one has rather sustained high windspeeds for effective power. The amount of power available to capture goes as the cube of wind speed. I.e. doubling the mean wind speed increases the power by a factor of eight...

Does this happen every time, or could it be a local/server data glitch?

Hmmm this side of the pond, 114kg is a pretty sizable individual. There is a whole UK installation manual; https://www.tesla.com/sites/default/files/pdfs/powerwall/Powerwall_2_AC_GW2_UK-EN_Installation_Manual.pdf Supporting the Powerwall from below with wood is not one of the options... All...

You might want to double check which QR code you are scanning on the Gateway. There is more than one.

@holeydonut My issue with sliding windows is the generally lower performance when it comes to air leakage; https://anlin.com/wp-content/uploads/2023/10/Del-Mar-Performance-Data-11.01.23.pdf Have you considered a different style of window? All the best, BG

I would not overlook the big improvements in blower technology that significantly reduce the power consumed in moving air for heating/cooling. There is also a mismatch in the air flow needs for a heat pump vs other types of furnaces that operate with a higher air temperature. I'm not trying to...

@wwu123 Yes the ratings are all based on the combination of components. Here in California, it doesn't matter for most folks, but in more humid areas, the most efficient evaporators may not get the air cold enough for optimal humidity reduction and the systems will therefore require an...

Randomized trial? E.g. doing something one way, and as a control (arm) not doing the something...

If you have a Tesla, there is charge on solar. Personally, I just set a low(ish) charge rate and times when I know the solar is likely in excess. I don't micromanage it as we are generally net exporters. What I do focus on is trying to use power when we have solar. Dead of winter, the car...

I would check the specification for your OLED TV, and get it in writing from the termite folks that it would be ok. Most electronics tend to have an upper limit of 50C/120F, because that's where a bunch of components are rated. I would make sure that it is unplugged if you leave it inside.

Setting the pricing to different values is just to influence the Powerwall/gateway to do what you want at the times that you want. Because, we, like @miimura have NBCs, I adjust the pricing to account for the cost of imports, and for the inefficiency of using solar to charge the Powerwalls...

If you find one that you like, feel free to share their contact information...;)

@Mayer you might get better answers if folks knew your utility/locale...

@wwu123 There is an upcoming webinar on HEEHRA/HEERA https://chpc.net/event/understanding-the-inflation-reduction-acts-decarbonization-rebate-programs-homes-heera-and-ebd/ Keep us informed. We are also considering some of the options. All the best, BG

To answer your original question, the termite heat treatment targets temperatures 120-140F that are just at or above the range for a running Powerwall (122F/50C) and at the upper limit for Powerwall storage (140F, per the Tesla Installation manual).

🤞

There are a number of threads around this, but basically why would you? The Powerwall is tiny by comparison, and you lose 10% by putting it into the Powerwall before charging...

During grid disconnections and reconnections, there is a heightened probability of "dirty" power. However, given the general history here, having a system damaged at power up seems to be an infrequent occurrence. I think that is due in part to Tesla having the gateway wait five minutes before...

Given that utilities manage to keep the lights on in other parts of the country that have snow, ice storms, and things like say tornados and hurricanes, I'm not impressed with PG&E's performance to date. Plus those other utilities don't charge PG&E power rates either. Just my$0.02... BG
