    Updates Found Here (Last Updated 10/9/24)
    - What's new with PW3 from PW2 (10/1/2024) If you want to learn the differences between PW2 & PW3, then check out this video ruclips.net/video/LWw8UvDki28/видео.html
    - Regarding capacity (10/1/2024): Capacity is 13.5 kWh, but there will be some conversion losses (~10%). Realistically there's ~12-12.5 kWh of capacity available under real world conditions.
    - Add-ons with NEM (10/8/24) Will adding a PW3 impact your NEM status (CA)? From Tesla: AS OF NOW...Yes. Customers on NEM 1.0 and NEM 2.0 can add battery storage later. For existing NEM 1.0 and NEM 2.0 customers, adding battery storage does not affect your existing status.
    - WiFi & Cellular connectivity (10/8/24) If concerned with a total lapse in the grid, wifi, and possible cellular then it may make sense to purchase a Starlink to complement the entire setup.
    - Software (10/8/24) For even more Powerwall automations or to monitor your system from your web browser, check out this app: www.netzero.energy
    - Remote Meter (10/9/24) With the release of Tesla's Remote Meter, the Powerwall 3 can be AC-coupled with existing solar with BOTH the Backup Switch & Gateway 3. Additionally, partial home backup with the Gateway 3 and Powerwall 3 is also possible.

    This is Cathy's husband Larry - we are both amateur radio operators - we just installed a Tesla PowerWall 3 and solar panels to our condo. I am seeing significant radio frequency emissions at set frequency intervals of 250kHz across the high frequency spectrum into VHF spectrum - for example, I have an antenna for the 20 meter amateur band and there are signals at 14.00MHz, 14.250MHz, 14.500MHz, and so on. These disappear when the sun goes down and the panels are not producing power. Also, last evening, just 4 days after the install, our HOA complex power went out. Our power also went out even with the PowerWall set up I thought for backup power. When I tried to disconnect from the grid, the app stated that we had too many appliances connected (we did not) which exceeded the capacity of the PowerWall. Today, with power restored, I was able to disconnect from the grid without the over-capacity message warning. Any ideas?

      For both of these scenarios, I'd reach out to your installer so they can troubleshoot this with you. I'd just be speculating on my end. Sorry, wish I had a better answer for you!

    Great context Zach! I have learned so much from you on the PW3.. Do you have experience or information on a non-export system. This was an option mentioned to me in CA, as I am currently in NEM 2.0 and looking to add a Powerwall 3 and possibly adding some more solar panels to existing system. My understanding is if I add solar panels I would be put in NEM 3.0, so this non-export system was referenced as a possible option with PG&E in CA. I just don’t know the pros or possible cons with this setup.

      I really appreciate that! Stoked to hear that my videos have been helpful for you 😎
      I personally don’t have experience directly with non-export systems. My main concern would be making sure your installer sets it up 100% correctly to ensure you don’t get pulled from NEM 2.0 due to this addition. Here’s more info on non-export systems from Tesla, although it doesn’t answer the PG&E part. energylibrary.tesla.com/docs/Public/EnergyStorage/Powerwall/General/Compliance/PowerControlSystemFeatures/en-us/GUID-E84DB70D-5596-40C4-8B57-2F606A86733F.html

      @@rubenvaz6497 Absolutely! You are right I could add a few more panels under NEM 2. In California, a non-export system prevents excess energy from being sent back to the grid. Non-export systems can be used to expand a solar system without losing the benefits of Net Energy Metering (NEM) 1.0 or 2.0. No one talks about this option as it is fairly new. You can still add powerwalls to NEM 1 or 2 without any issues of getting bumped to NEM 3. I decided to get just upgrade to the Powerwall 3 for now and down the road I will setup a Non-export system.

      You should be all good for the Gateway 3 & remote meter. If your installer has Gateway 2s in stock, then they might use those. If not, you’ll have the GW3 with the new RM. Either way, you’ll have full monitoring.

    • @ZachSolar
      @ZachSolar  Месяц назад +2

      Hey Joseph, the PW3 can handle up to 185 LRA. Is your heat pump under that mark? If yes, you’re good to go as is. But if you are over that 185, I’d say that soft start is the way to go. However, on older AC units I know hard starts are a popular option but I don’t believe they reduce the inrush current.

If reducing strain on the PW3 is the goal, then I'm almost certain that a soft start would be what you need.. Soft starts reduce the initial inrush current. Hard starts increase that initial inrush current. I'd clarify why they are making that hard start suggestion and if a soft start would make more sense. Hopefully this helps!

    Great Q&A, Zach. Regarding #42, if the WiFi goes out, you can still communicate with the Powerwall 3 through the app. Our home internet went down for the entire day yesterday, but we still had great sun. I was very curious what would happen because I thought the PW3 relied on WiFi to operate. I was still able to see the solar and PW3 through the app, the system continued to work as normal, even charging my MYP “on Solar”. Clearly the PW3’s just pivoted to cellular and operated normally. I also was able to change Powerwall settings while my WiFi was down. My units are not Ethernet connected.

  • @thomasvikoren3981
    @thomasvikoren3981 11 дней назад

    Two quesitons... 1: I have an agricultural building that faces south and has a subpanel fed from the house via a 200A 250mcm 4 wire underground connection. If I put solar on the ag building would powerwalls also be installed in that building? How about the gateway - same building or back in the residence? Are additional wires required or does the solar and powerwall connect directly to the sub-panel in the ag building and back feed via the existing feed?
    Second question: the residence has a 400A service with multiple 200a sub-panels feeding a different garage and two sub-panels in the house. Thus a backup solution would need to have multiple 200A gateways which is impractical. What is the potential for a future 400A gateway or 400A backup switch? The most practical solution for me would be solar on the ag building, powerwalls in the ag building and 400A gateway at the service entrance in the residence. Hopefully this could become possible. Thanks , great video! - Thomas

    • @ZachSolar
      @ZachSolar  10 дней назад

      Thanks Thomas! I'm glad the video was helpful 👍
      1) Both the Powerwall(s) and Gateway may be able to be installed on that building and backup that subpanel. My concern would be any utility pushback or AHJ restrictions with it being further away from the main. I'd find a local installer out there and see what their thoughts are.
      2) I haven't heard anything about a 400A gateway or backup switch coming from Tesla, but I might be out of the loop. Installing 2 Gateways is the most common work around in this scenario.

    If one has a single meter, but 400 amps service (2x200 amp legs) can it be set up to feed only one of the 2 legs? Does that require any special/expansive hardware?

    • @ZachSolar
      @ZachSolar  Месяц назад

      Yes you can do what you described. The gateway can backup 200A. So if you wanted just one of the 200A panels backed up, then only 1 Gateway required. If you wanted for both to be backed up, then 2 Gateways would be required. You can’t use the backup switch on a 400A service either.

    I was told by a Tesla rep that came to my house for an assessment that my Cybertruck will be used and looked at via the gateway as an additional battery. They also said I can use the truck and it will not void the warranty...no matter how much I use it to power the house

    • @ZachSolar
      @ZachSolar  Месяц назад

      Not sure if you have this set up yet, but will your Cybertruck discharge any energy to the home when on-grid like a Powerwall? Or only when in a grid down situation?
      My understanding is that the Cybertruck would only discharge to the home when an outage occurs. Maybe I’ll have to go buy one for testing purposes 🤪

    • @SFzip
      @SFzip Месяц назад +1

      Also, from what I understand, the Cybertruck cannot function as an additional battery in the traditional sense. It can only serve as backup power during a grid outage and *cannot export energy to the grid* for VPP or other purposes. The reason for this limitation is to prevent users from charging the Cybertruck at a different location and discharging it at home, which could create imbalances in energy distribution.

      Great question. Let me get confirmation. As a PW2 owner, I hope it could work. My concern is the fact the PW2 doesn’t have the same port the DC pack uses for wiring the batteries together. But perhaps there’d be a work around, however I feel a standard PW3 would be needed.

    • @ZachSolar
