    Does grid fluctuation or dirty power cause PW to interpret as grid outage for 5 minutes?

    Re my neighbor's tracking. I suspect he uses somewhat un-scientific observational methods.

    Does grid fluctuation or dirty power cause PW to interpret as grid outage for 5 minutes?

    Have had my PW2 for about 15 months. While I've only had a couple of grid outages lasting more than a few minutes, maybe for an hour or two, I do get a lot of supposed "outages" for 5 minutes that I suspect may not be true outages. I have a neighbor that tracks outages closely (so as to get...

    Tesla changed order from PW+ to PW2 - Worth it to still move forward?

    If the main advantage to PW+ is to start up your AC, that could be accomplished by a $250 soft-starter.

    PW recharging behavior with no sun

    Apparently, I mis-remembered. Looks like it did charge OK the next morning.

    PW recharging behavior with no sun

    Here's the better screenshot. As far as spike, think I turned AC off immediately with app, could be one or both dehumidifiers, but don't think one uses that much juice. Thanks for the explanations re charging for the grid, very helpful in understanding this complicated technology.

    PW recharging behavior with no sun

    Is there any downside to having installer set PW to charge from grid. Presume it would only do that if no solar available? After first PW was installed, I came to understand I needed two, which is why I've been waiting 14 months for #2.

    PW recharging behavior with no sun

    Screenshot of day in question, 6/25/21, attached. Grid outage approximately 1745 - 1850. App was set with Storm Watch on but don't know if it was actually activated. I don't remember seeing it, but hard to say at this point. I've seen the Storm Watch activated maybe five times in 14 months...

    PW recharging behavior with no sun

    Not sure if this is normal or not. Have PW for about 16 months now. Have 12k solar but PW is backup only. Have one PW, been waiting 14 months for second. True operational grid outages in last 16 months have been few and short. While out of town a couple of weeks ago, during a thunderstorm...

    Ford Bi-Directional Charger for Ford EVs (and maybe Powerwalls?)

    I'm not interested in V2G, only V2H as a way to add backup capacity for my one PW (been waiting 14+ months for PW#2). Since I may never need my backup PW, it might be money sunk like insurance you never use. But, with say, the Ford F-150, I could get to use an EV daily while also having the...

    Ford Bi-Directional Charger for Ford EVs (and maybe Powerwalls?)

    Just saw the old news today that Sunrun will be installing 80 amp bi-directional charging stations for the 2022 Ford F-150 Lightning EV Sunrun To Install 80-amp Charge Station For All-Electric Ford F-150 Lightning Any thoughts out there on being able to integrate this into an existing 12 kW...

    which custom mode you should choose for powerwall with net meter and no time based rates?

    I have net metering and set PW for "backup only 100%." While I understand battery will live longer at 70-80%, that will suck if the grid goes out, somewhat defeating the purpose of having the PW. I leave it set at 100%, which means it's usually at 97-98%, rarely at 100%.

    Backup history detail?

    If the outage is more than 10 minutes, you will get a push notification. That gives a reasonable proximation of the time, but no permanent record. Yeah, wish it would always give the time in the history section.

    Powerwall Backorders

    With or without solar system? Tesla or 3rd party installer? Thanks.

    PW phone app backup notification

    On a side note. I compare power outages with a nearby neighbor who has no batteries. Sometimes my app will say I had a brief outage, say 5-10 minutes, that my neighbor doesn't concur with. I don't know if I had an outage or not aside from the app history saying so. Previously, most of out...

    Powerwall Backorders

    My 3rd party installer has mostly given up on Powerwalls for now and installs Generac and some other brands. I think the only ones still on the Tesla list are like me, awaiting an additional PW.

    PW phone app backup notification

    Have had Powerwall since Feb 2020. Previously, would only get Android app (v20.49.0) push notification if outage exceeded 10 minutes. Only other way to know about power outage is to periodically review history. Don't remember if there was a notification sound; been several months since an...

    Powerwall Backorders

    Think it was mid-2020, I was told to expect delivery in 2021 Q2. In Q2, about a month ago, I was told Q3. After reading stories about Tesla not meeting contractual prices on roofs, I'm not expecting my mid-2020 price to hold whenever I do get the battery. Think there's been two $500 increases...

    Powerwall Backorders

    Also, how have the price changes affected backorders? PW has had two $500 price increases since I ordered. Does Tesla honor the original price at time of order?

    Powerwall Backorders

    Had one PW installed in February 2020. A few months later, I realized I need a second one for my 12k solar system. Ordered it from my same local third-party installer around the first of June. A few months later, installer told me they're backordered until first quarter of 2021. Well, here we...

    Model 3 AC Smell Update...

    I don't know about the Model 3 specifically, but generally to avoid AC mildew/mold odors: 1. avoid/minimize use of AC recirculated air 2. turn AC off but let fan run with fresh air five minutes before parking in garage at work or home for the day (also reduces water on garage floor) These...

    System Size vs Estimated Annual Production

    Depends how you look at it. If you have a $100,000 house and it's insured for $100,000 and you add $10,000 in solar, you now have to pay for $110,000 in insurance. If you have a $90,000 house insured for $100,000 and you add $10,000 in solar, no change to your premium. They raise your rates to...

    System Size vs Estimated Annual Production

    My insurance company, USAA, only wanted to know the cost of the system to be insured.

    System Size vs Estimated Annual Production

    This could actually make a big difference. I have 320w panels but my microinverters cap at 250w. Therefore I have a lot of clipping, although they overclock to about 275w. Is this common, for installers to put in microinverters that are "underpowered" compared to the panels? I don't understand...

    PW phone app backup notification

    This is a critical function--not just nice too have--I, and I'm sure many others, have to manage household use of power while on battery. Can't manage if you don't know about it.

    Why I ordered 22+ kw solar glass roof for $134k

    Correct. Same happened when my home was appraised. No comps = no added value. There is a method to appraise without comps, but nobody wants to bother with it.

    PW phone app backup notification

    After installing PW2 and doing 6 outage tests over the first 6 months, I got the phone app push notification when power went off and also back on. The notifications, both power on and off, appear to be delayed about 10 minutes before receiving push notification on phone app. Is this normal...

    2xPowerwall whole house backup - HVAC sure start problem

    I have new Carrier equipment and asked my HVAC contractor about the warranty. He said no problem, just won't warranty any issues directly related to the soft-start (which would be a soft-start warranty issue). That makes sense. Soft-starts actually help extend the life of the AC units.

    Yep, those are the same two part numbers Hyper gave me for my 2-ton & 3-ton. Make sure they don't get mixed up.

    Don't think this guy would be of any help then if Hyper says it won't work, but can see what he says.

    2xPowerwall whole house backup - HVAC sure start problem

    This guy says he's the one that partners with Tesla to provide the SureStart. Even though the generic wiring instructions should be sufficient, he said he would mark up the factory compressor wiring diagram for any customer to remove any chance for error, which seems to be common, reading this...

    2xPowerwall whole house backup - HVAC sure start problem

    I'm neither an electrician or an HVAC tech---but I did play one on TV. On my indoor panel, my 2-ton has a 20 amp and my 3-ton has a 30 amp breaker. Outside, on the AC units, they both appear to have 60 amp ACD (Air Conditioning Disconnect). I believe these are just for the HVAC techs to service...

    2xPowerwall whole house backup - HVAC sure start problem

    You'll probably be OK if you're careful. Do not get the hard start kit. It is different than a soft start kit. Free PW? Still not quite enough to entice me back to California.

    2xPowerwall whole house backup - HVAC sure start problem

    Maybe. I'd say you're borderline. Being 14 years old, your LRA is probably a bit higher. Test it as OP says. I think SureStart guarantees a 60% reduction, but may get 70%. AC start would soak up 40 of your 58 amps available with two PW. As long as no electric oven, cooktop, dryer, etc...

    You must not live at the beach. What brand/model/size/LRA are your two AC units? Thanks.

    2xPowerwall whole house backup - HVAC sure start problem

    Guess I should have said all inverters shut off no higher than 61.5 Hz, which is code. Hyper told me 60+/-3 Hz via email, they don't seem to have a phone number listed on their web site.
  36. B

    2xPowerwall whole house backup - HVAC sure start problem

    I contacted Hyper Engineering Tech Support. The SureStart is 60+/-3 Hz. All inverters cut off at 61.5. Powerwall default is 65 Hz. I had Tesla remotely reduce the PW to 62.5 Hz. That will work with the SureStart.

    2xPowerwall whole house backup - HVAC sure start problem

    Does Tesla include the SureStart(s) in the overall price or is it added on extra depending on whether they're used or not? Thanks.

    2xPowerwall whole house backup - HVAC sure start problem

    You're assuming we all have Fluke meters. And, we can't measure the SureStart effects until we have them installed. For now, I have to work with specs. Thanks.

    2xPowerwall whole house backup - HVAC sure start problem

    Enough to make my head spin for a while. New construction. I have a 12.1kW PV system with two AC in a reverse 1.5 story with walkout basement. The lower level doesn't really need the 2-ton AC (but does need the gas furnace). I got it more for dehumidifying, but then it overcools so I just use...

    2xPowerwall whole house backup - HVAC sure start problem

    I had a Generac 11kW on my old house. Installed about six years ago, it had a load shedding capability for two AC (I only had one) but no soft-start. Never really needed the backup over that period so don't know if the AC would have worked. As I look back on specs, probably would not have...

    2xPowerwall whole house backup - HVAC sure start problem

    This is not quite correct. The issue remains with generators. Just as you may need additional PWs to start your AC, you'll need a more powerful generator to start your AC. Your house may only need a 15kW generator without AC, but with AC, might need a 22kW generator. The big difference is the...

    Mach E in the wild

    I saw the Mach E at an auto show in March. I think it looked great and better than these pictures show. Since looks are mostly all people can know at this point, it's managed to sell out the initial batch several months before release.

    Second PW Installation Cost

    Had a single PW installed a couple of months ago. Unfortunately, the recommendation of the installer was incorrect and I actually need two. The installer is an authorized partner and install was fine. I paid $11,500 for the install. Taking out the material costs (Battery $6,500, Gateway $1,100...

    Powerwall 2 + UPS Connundrum - and solution

    My microinverters are set to operate up to 60.5Hz (AP YC500). What would be the lowest safe shutoff setting? Is 61Hz cutting it too close? I have a third party installer, can they do it or would they also have to call Tesla? Thanks.

    Powerwall 2 + UPS Connundrum - and solution

    My two CyberPower UPS, 63Hz max, weren't happy with the Powerwall 2. I may have missed this skimming over this 17 page thread. Where can I find the current shutoff frequency setting? I can see the normal operating frequency of each microinverter (60.5Hz) through the APsystems web based app. Page...

    Misleading Capabilities of Backup Mode?

    It's hard finding pricing online, most places want you to register (as a pro?). After reading this article, I raised the price issue at the time of making the decision (Nov-Dec 2019). Although this article clearly states the YC600 is much less expensive than IQ7+ (at least in June 2018). My...

    Misleading Capabilities of Backup Mode?

    While I wouldn't otherwise replace the YC500s, since the installer didn't provide the microinverters as promised, I'm trying to figure the impact of me requesting an exchange for the YC600s. A whole new system design sounds deal-breaking. Looking at the spec sheets, the YC500 says "Maximum Units...

    Misleading Capabilities of Backup Mode?

    This appears to be true if the panels had their performance reduced to the inverter's capability. But, would you "have your cake & eat it too" if the inverter's performance was increased to meet the panel capability? Maybe I'm missing it, but if the inverter could increase up to the panel, you...

    Misleading Capabilities of Backup Mode?

    I understand the microinverter bell curve and how clipping can be both harmful & beneficial. I don't know, in my situation, if it's something I should complain about. Maybe, the bottom line is my production in the first ten months seems to fall about 10% short of the projection in the contract...
