Comparing Ecosystems - Tesla vs Enphase

[@jeffgill7068]

I love the Schneider Electric shirt! Life is On!

[@andyatmosphere]

Epic!

[@trstrean]

I could be wrong, but i think the Span panel also adds most of the effects you mention for the powerwall. It has a software critical load and I think it does the switch also. Between that and using a Franklin aPower 2 and aGate.

[@Remotesteve2]

kudos for even making this comparison most non tesla solar companies are too biased to entertain the value of the Tesla ecosystem(outside PW2). Regardless I think an increasing percentage of the market will not wait for Enphase/Solaredge etc to catch up. Tesla inverters are underrated and the fact that now consumers can get a power wall 3 for a few thousand more than just an enphase system will sway many!

[@ScoobyFermentation]

Bidirectional charging IS the future.

[@crcurran]

Yeah it is. I'd like a EVSE DC EV Charger to go from solar direct to EV battery without all the conversions. Onboard AC-DC converter for charging are terrible inefficient.

[@csf1757]

I wonder if the APIs for these systems could be consolidated and included in a future version of Matter so that all brands could work together?

[@theorosenberg]

Thoughts on an Enphase system but with a Tesla Powerwall 3?

[@dalerolph]

More on that soon! But I can say it does make more sense if you’re purchasing a new system to get a complete ecosystem. However there are millions of us with existing systems that need batteries, that is where I think you’ll mix and match more often.

[@Rodrigoc_AGreatSun]

Could we add a Tigo to monitor production at the panel level with the TPW3?

[@dalerolph]

I don’t see why you couldn’t do that, the PW3 works without the need of optimizers or rapid shutdown devices. It would be nice if SolarEdge would open their platform up so other companies could leverage their proprietary optimizer technology.

[@jabbathespud]

No. Tesla has stated that using such devices will trigger arc fault interruption. Only the Tesla MCI's are allowed.

[@michaelpettit1263]

What is the point of a meter collar on an enphase system? The System Controller 3 takes the two hot legs and the neutral from the meter, and sends two hot legs and a neutral to the home breaker panel (in the whole home variant of the setup). The ATS is in the System Controller. Very simple to wire, no extra funky boxes. The limitations on battery current are down to the bus bar limits in the System Controller 3. If you forgo integrated generator support, you can push 160 amps continuous during an outage.

[@PHamster]

Here’s the biggest thing, can someone with the Tesla PowerWall 2 (not plus with the inverter on top) use the meter collar.

[@dalerolph]

No, the PW2 does not have the necessary hardware to do that, you need the gateway (at least at this time). The PW+ and PW3 have all necessary hardware for backup switch.

[@crcurran]

You mention the benefit of Microinverters but leave out the use of Optimizers which would give you nearly the granularity when troubleshooting individual panels.

[@dalerolph]

I did a separate video talking about SolarEdge since they’re kinda the only manufacture with an integrated system using module level optimizers. This does increase components and costs so it’s a matter of deciding how valuable that granularity is as either A) a contractor or B) an owner of the system.

[@solargod3671]

SolarEdge sucks I wouldn’t depend on it on my life.

[@canokrd]

Here in Puerto Rico we all need the backup 😞

[@jingyu447]

Hi Dale, will you be interested in reviewing our new Avalon Wholehome energy storage solution which has built-in load shedding, level 2 EV charger integration?

[@dalerolph]

You’re welcome to send a sample system to our office at 41775 Elm Street Suite 102, Murrieta CA 92562 for review.

[@jingyu447]

@@dalerolph , will do! Thanks!

[@StevenC1961]

Is the Meter Collar rated for 200 amp service??

[@dalerolph]

Yes, it's rated for up-to 200 amps continuous which is perfect for the majority of residential homes. You can learn more at www.tesla.com/support/energy/powerwall/learn/tesla-backup-switch

[@terrya6486]

I love to see the technology evolved. I am so glad.I left the power grid seven years ago.

[@gordonlowe5405]

Hoping that our local energy provider, Evergy, approves the Tesla Backup Switch within the next several months.

[@csf1757]

If you have a 400 amp system, 1 meter with 2 separate 200 amp supplies, will this collar work? Would you need 2 meters Ids it legal (anywhere in NA) to have 2 meters on incoming powerlines?

[@irfanwaseh]

I have Tesla. Tiles 12 kw tiles but inverter is 7.7 3 strings coming to inverter plus to power walls during month of march to mid November it getting clipped from 9 am to 4 pm what will be the options for me near future if I want to get upgrade to Tesla 3 what u suggest ?

[@dalerolph]

Please email system data to [e-mail] and our team will review for you.

[@tajdvl-advocate6113]

You didn’t mention the system reliability upside AC architectures have when it comes to panel level redundancy. The Enphase architecture can also more effectively deal with panel output voltage variability due to degradation of output voltage at the panel level be it by localized shading or cell failure within the panel or even complete failure of a panel.

[@andyatmosphere]

I'm a Mechatronics Technician. I've installed variuos systems throughout the world. Let me know if need some help on your install team.

[@stephenbrickwood1602]

Enphase can not cause rooftop fires. Enphase allows fire fighters onto the roof as all panels shut off when street supply shuts off.

[@zodiacfml]

11:08 this!!! while the PW3 is impressive, it is still a generation behind including its EVs. At this point, Tesla PW should have capability to DC charge an EV whether it comes from solar or battery to avoid losses with DC to AC then AC to DC conversion. In addition, Tesla EVs should have V2G by now. The current system on the Cybertruck is not V2G and will require a separate hardware to power a house. Hopefully that new hardware should be able to talk to/integrate with the PW3. But then, that is convoluted whereas a Powerwall should be able handle all these. Ugghgh, Nissan/Japan have the V2G idea for around ten years and no product does it seamlessly

[@mondotv4216]

That's incorrect. For V2H all you need is the Tesla Wall Connector and a TPW3. Plus the Gateway or the Meter Backup switch. But you needed those elements any way to have backup power for your home. Of course you need a Cybertruck but compare that to the Ford's F150 system which requires a separate inverter installed at your home. Nothing supports V2G atm - all you have is endless trials and it's the grid that needs to get on with it. There is talk that Tesla will eventually get this working with PW2 setups. The limiting factor is really the Cybertruck. Hopefully future Tesla's will all come with this capability.

[@zodiacfml]

​@@mondotv4216 Correct on that wall connector, basically a thick, more robust cable versus plugging into the AUX port found at the bed. It is trivial for Tesla to add V2G to their cars, all its needs is a sensor or Powerwall that detects if there is any excess power going to grid, or the car inverter perfectly matches the current electricity load of a home.

[@legalbeagle5712]

So tesla backup switch is the current best design

[@dalerolph]

Backup Switch is the most cost effective option, since you do not need the Tesla Gateway or an electrical sub panel, labor cost is reduced significantly as well. We have Powerwall 3 installed with Backup Switch with a new solar system (not existing) for $10,500, and with Gateway $14,000. In Arizona we have a partner installing Powerwall 3 with Backup Switch at $9,900, it's a game changer for homeowners and businesses.

[@cjb8993]

I prefer the Tesla power walls as they are much larger however, I'm likely forced to go with Enphase because the Enphase system will play with my whole home back up generator, Tesla's system unfortunately does not.

[@dalerolph]

You can use the Tesla Powerwall upstream of a generator backup system but you’re correct if you want it to charge the batteries you’ll need to go with Enphase for that.

[@cjb8993]

@@dalerolph yes sir, pulled the trigger today, went with Enphase, and it wasn’t cheap!

[@dalerolph]

@@cjb8993 too bad you weren’t in our service areas, we currently have partners in California, Arizona, Texas and Florida. Though for battery add-on we’re limited but would’ve looked for a good partner for you. Glad you got something worked out

"The International Energy Agency (IEA) predicts that globally 'electricity consumption from data centres, artificial intelligence (AI) and the cryptocurrency sector could double by 2026.' By 2026, they say global data centers' energy demand will equal that of the entirety of Japan. There are currently an estimated 2,700 data centers within the US according to the IEA, which sapped over four percent of the nation's electricity in 2022. They predict that by 2026, their consumption will rise to six percent. The rise is being driven largely by developments in AI, cloud computing and cryptocurrency mining all of which require large data centers which in turn consume vast amounts of power. " ~by Isabelle Stanley, For Dailymail Maybe we should all be getting solar and battery not just to protect ourselves but to help the grid too. And in some places there will be pay from the grid for our solar-generated electricity.

[@ScoobyFermentation]

For most people around the country, Tesla is not even an option. They don’t serve a lot of states. Also, I thought string inverters don’t do as well with shading? Surprised it wasn’t mentioned. Unless you live in California with a perfect roof for sun, Tesla is not a good choice. Finally, I know you can’t say it, but Tesla’s customer service is a crap show in my opinion.

[@knekker1]

The shading issue, doesn't come down to whether you live in California or not. It's about whether your rooftop is going to be surrounded by trees casting shades onto it. In such case the Enphase sounds more ideal.

[@ScoobyFermentation]

Thanks for the definition of shade. Do you also know the definition of wet?

[@knekker1]

@@ScoobyFermentationOh I am sorry, I did not intend to hurt your fragile ego by correcting you.

[@dalerolph]

Solar panel technology has come a long way and shading issues aren’t as big as you might think plus having six inputs on the powerwall 3 you can mitigate that with a proper dc string design.

[@mattbrew11]

Hopefully they stop doing direct installations altogether. A reputable installer can provide the equipment AND do customer service

I think this is good content, but the presentation lets it down a bit. When you talk, and talk....and talk - an endless stream of words with no gaps - it is hard for us as listeners to organise our thoughts because more words are being shoved in our ears. There is no room for us to THINK - about how this fits (or not) with what we already know. So it's not a good learning experience. There is a bit of repetition too, which could be removed with planning. Can I recommend someone with REALLY good planning and delivery - perfection, in fact - to emulate? It is www.youtube.com/@GaryDoesSolar I know it's UK-focused, but it's the presentational style that I'm drawing attention to. This isn't discouragement, BTW - the opposite!
