Sorry, I’m definitely aware of that. Some of these numbers are under the assumption no solar energy would be coming in (during a storm, at night, etc)

@ Why would you assume that?

You missed this part 3:24 I mention a single unit can last 24+ hours and incoming solar will recharge the battery and power the home.

Do you have a Powerwall system already or are you installing just the Powershare setup (No Powerwall, GW 3V and Universal WC)?

@@ZachSolarwe are waiting for our system to be installed. Powerwall 3, gateway 3, 9.6 solar, universal wall charger. It’s my understanding communications is needed for the “charge on solar” and future PowerShare settings.

I would love that too! Hopefully soon 🤞

That's a good question. Short answer is kind of. It won't necessarily prevent it from going below -4 degrees, but it should help optimize the cell temp. This information on the Powerwall's "Heat Mode" might be helpful for you. energylibrary.tesla.com/docs/Public/EnergyStorage/Powerwall/3/WhitePaper/HeatMode/en-us/Powerwall-3-Heat-Mode-White-Paper.pdf

Nice to hear! That's a solid sized setup from So. AZ. A 2nd Powerwall would be a good addition. When you're ready, let me know if you need any help getting an expansion pack. I'm in Tucson and can set you up.

Oh brother 🙄 send me the data supporting that

Very cool, Jack! Your system and utility sounds very similar to mine. I'm just holding out for Powerwall 3 to become compatible with my 2s.

@@ZachSolar We would love that, but we were told the 'kit' would be available at the end of '24, so we will see.

Nice! It will wear off lol. If you have an iPhone, add the Tesla widget to the Home Screen to make it easy for ya

Standby is completely normal. Anytime the Powerwall is neither charging or discharging, it’s in standby. This can happen for several reasons depending on whether you’re in time-based control or self-powered. Hard to say without seeing your app’s history and power flow though.

Absolutely. Each PW3 has a max charge rate of 5 kW, so 3x gets you 15 kW. You may have to grid charge during some time of the year to fill them up to 100% though depending on how low your backup reserve will be.

@@ZachSolarsounds good. Thank for the info again.

Happy to assist! I can help with that. calendly.com/infozachsolar/support

Let me know if you have any Qs on the exp packs!

Thanks! And shoot, I'm certainly not the most DIY inclined person here in YT. I wouldn't be confident in my feedback on that. But it sounds like a really interesting project.

How strange. That’s very disappointing to hear. I hope you get a resolution ASAP.

@ any ideas why this might be happening? I know it’s a long shot, but anything can help…awesome channel👍

@ Thank you! And shoot, I wish I had even a good guess. I imagine Tesla would be the only one who could get the right answers for something like this. Does it discharge itself randomly even when on Self-Powered control? Or only on Time-Based control?

@ yeah discharges randomly no matter if on TOU or self consumption mode…so weird it’s only little blips of energy discharge, but eventually blips add up and battery loses a few %’s and if my Tesla is charging of solar during that time….car stops charging to prioritize the battery, once it hits 100% again, battery starts to discharge again

The cost for the DC expansion was $11k

Thanks Mike! Keep me posted on your expansion pack experience. That's cool you already have one lined up and about to ready to go. Hard to beat a Solar + Powerwall + SPAN setup. Enjoy it!

When my system is installed, I'm also planning a min 40% reserve. Then, using the PW3 Storm Watch feature, I'll charge up and maintain 100% until the bad weather has passed.

Server rack is a great option too. Just a different market of buyer IMO. Did you do your own install? I can't remember. I know you got the REC Alphas.

@@ZachSolar Yes, I installed the inverter and batteries in my garage. I hired a licensed electrical contractor to install the panels on my roof, run the electrical from my main panel on the south side of my house to my garage on the north side through the attic (about a 60' run), and back to a subpanel next to the main.

@DerekRhoads Cool setup, Derek! I’m sure that was a fun project to take on.

Good point! AZ utilities are very unique with our demand charges. You must have a strong export rate too. APS is under 7c/kWh nowadays for their buyback.

Got the $0.07619/kWh buyback. Laughed when the Tesla app didn't allow buyback rates to be higher than the purchase rates.

@@jabbathespud Haha, Yeah it's a very uncommon situation to have that come up. Idk why they still don't allow it. Probably to prevent people from getting the numbers backwards.

I've been waiting four months for mine. Finally decided to pivot and installed Tesla Solar inverters while waiting for the PW3s. When the PW3s become available it'll be easy to swap the inverters for the PW3s. By going with the Tesla inverters the solar roof configuration can remain unchanged.

This is definitely an issue for all installers right now. Probably will be through Q1 of this year. We aren't seeing anything quite that long on our end. It will be well worth the wait though!

We are installing the same system in a couple months. What are your biggest loads that keep you from making it through the night with your single Powerwall?

That's the perfect strategy with 1 Powerwall. Adding some more kWh would be a nice addition to help lower your overall grid usage.

@ I am saving up for it.

@@leafnutz2341 The heat pump in heating mode ( our home is 3200 square feet), and refrigerators compressor, and water heater.

Love it! Thanks for sharing the details. 4 Powerwalls is a beast of a system. Ya know, there’s only one problem with the system though…you didn’t get it from me 😉 just kidding. Glad to hear it’s working great!

Hmm, I've never heard of this before. I'd have to imagine if the utility and AHJ approved everything for installation and power on, then it's all good to go. I don't know of a setting in Tesla's software that would automate this.

That's an amazing setup. Tons of kWh!

Initially yes, but since this video’s upload the backup switch can now be used on an AC-coupled system (add-on).

This is the kind of real-world feedback I love to hear. Thanks for sharing!

I don’t think you’d need to do anything special. A bitcoin miner would use electricity just like any other appliance in your home. You’d just need to factor in the additional energy consumed by it for proper sizing.

Honestly, I'd consult with a local installer on it as they may have different preferences on how it's all done depending on your situation. I think generators just complicate everything with the Powerwall system IMO. I'd rather use that money towards an additional Powerwall to expand capacity. Here's more info directly from Tesla on generator integration though: www.tesla.com/support/energy/powerwall/learn/combining-systems

@ I agree it would be easier to have multiple Powerwalls but in a sense I’m hedging my bets with the availability of gasoline and solar power.

@@jchao003 That's fair. I see what ya mean. It's definitely doable, just going to come down to the preference of the installer & possibly even your specific jurisdiction.

@ Right, thanks for your insight. Plus, with a short 15-year lifespan, solar panels and battery backup systems require pricey installations/replacements.

Yeah in CA, it's a no brainer. Energy rates are wild out there.

While they a very similar product, there are some nuances and differences between Sigenergy's option and PointGuard's option. Max capacity is one of them. You are correct that in either case, each stack would operate in parallel, independent of each other, with it's own inverter from my understanding.

I haven't done a lot of homework on 3-phase as it's not something we ever run into on the residential side here in the US.

​@@ZachSolarOK thanks. It's becoming increasingly common here in Australia, with a home builder that I'm considering using, including it as standard for all new builds. 220-240V 3-phase is particularly useful when it comes to charging a couple of EVs at home... A lot faster than your typical 110V in the US.

Good to hear! Enphase makes a great product

Thanks! And not yet. I will be doing a new video on the Tesla app later this year for 2025. That's something I could include. I believe Tesla has all of the rates automatically set and available to select for the major CA utilities.

That's a good point. I can expect that supercharging for free to then power your home with Powershare is almost certainly going to be a no-no too.

@@redoc69 I’ve never had to do a calibration personally so I’m not sure. If it’s getting caught in a loop it’s definitely a software glitch. That’s frustrating though!

@@ZachSolar Pretty sure it's built in the system and starts automatically ~2 months after power up per Tesla rep and verified by Netzero. My 1st kW was produced 11/14/24- PTO 1/8/25 (sad) and it started calibration 1/13/25 @ ~ 22:00 and ended 1/16/25 @ 11: am. I could see on Netzero something was wrong and I contacted Tesla. They said it should take less then 24 hrs.. So after I called the second day they said they would monitored it and fixed the problem. My problem 100 kWh off the grid for those 3 day. Have a 21.2kw system 23 JA solar DP 3.0 $00W and 3 Pw3's. 2450 sq/ft home. with hot tub. Sorry for the bla bla but hope it helps someone. Great Site and knowledge. Thanks .. Great Site !!

@@ZachSolar I does it automatically after about 2 months of power up. It will stay in a calibration loop and Tesla is aware for the problem. I called after 2 days and they said they would monitor it in the morning. It went back on "online" at 11:00 the next day and started to take a charge.

Try going to your Powerwall site on the app, then settings, vehicle charging, and scroll to bottom to select vehicle for charge on solar. See if that works.

@@ZachSolar turns out (surprise) I'm an idiot. My Tesla Solar System hasn't been turned on by the local utility nor has it been registered with the utility or with Tesla... so, DUH on me!

@@TomUlcak lol, you’re just excited to get things rollin’. It happens 🙃

Thanks, Moe. Appreciate it

@@bertwright1790 it’ll be compatible once Tesla releases the update for it. Every Powerwall system will be. Not sure when, but they say 2025

I can't speak for Tesla's timelines. They've always been notoriously slow as an installer.

That’s a fantastic price. Is that installed with the backup switch or gateway?

Don’t know it just says all brackets, wiring, etc. included. Do you have any suggestions? I have a central inverter

Nah it doesn’t make a difference. It’s all the same at the end of the day. I was just curious.

Sunrun will install a battery system on your home (the "System"). which will include:  Battery(ies) (store electricity): 3 Powerwall 3 1707000-xx-y (AC Coupled) battery(ies)  Associated brackets, wiring, and electrical equipment (junction boxes, etc.) TOTAL CONTRACT PRICE The Total Contract Price for the System, including applicable taxes, is $31,900.00.

If the export function is OFF, it will curtail the solar once the battery is nearing 100%. Are you on time-based mode or self-powered?

@ZachSolar I am on self powered..

@@lovablebigt Very odd. If in self-powered, the battery should take priority over exporting. My only other thought is to set it to a higher backup reserve to force it want to hit that benchmark. Sorry, it's hard to say without seeing it so I'm probably not too helpful.

Thank you! And yep, that is a great opportunity to take advantage of. Are most installs in UK solar + storage?

No concerns at all. If you have a Powerwall system of any kind, it is compatible with Powershare (assuming the vehicle is). 5:44

Thanks for watching!

@@rlee4227 I know, I was shocked they didn’t include it for Android.

@@Chris-em9uw it’s a safety measure. If the battery is >90% during an outage, it will shut down the solar and discharge from the battery until below that ~90% threshold. This is to protect the battery from overcharging since solar generation can fluctuate so quickly.

@ my batteries are at zero due to these my land fires we have in Southern California, but the solar panels are not charging the batteries now. Do you have any clue why

@@Chris-em9uw shoot. My best guess is that they are fully discharged and there’s not even enough energy to get the solar online. Did they hit 0% while offgrid?

@ yea

What happen now

I agree, both of these options look great. Impressive numbers.

No problem! Happy to assist. Yeah, you’d have to go with 2 Powerwalls due to that 7.68 kW cap. You could also go with 1 Powerwall and just downsize your SolarEdge inverter to a 7600 or re-string the panels to a DC-coupled design using Powerwall’s inverter. Your 9.75 kW system would be completely fine on a 7600. If you need help getting a quote from an installer who knows what they’re doing down there, just shoot me an email at infozachsolar@gmail.com and I can help.
