Tesla Powerwall II+ VS Generac PWRCell for Whole House Backup 

You’re right. This dude is trying hard to make the Generac system look feasible.

@Bowhunters I 🤔 and correct me if I’m wrong? The whole point of this exercise apart from back up power is to stop burning fossil fuels.

@@wobby1516 you also need to consider that rare earth minerals are mined for batteries and solar panels which affects the environment also the disposal of batteries after they can no longer charge then having to replace them. Also the transport of materials via fossil fuels, production of materials via fossil fuels. I really don't consider these least mentioned issues as going green. With that said I do believe we should all be stewards of the environment and do energy wise and environmentally friendly actions. Simple things like keeping tires inflated, setting thermostats higher/lower. Increasing insulation and radiant barrier in attic and walls. Replacing older windows with better insulated ones, replacing curtains with insulated curtains. Growing trees to shade parts of the home and produce oxygen, Water conservation, reduction of fertilizer on lawns and gardens, using biochar on your lawns and garden for soil health and a "carbon" sink, Composting yard wastes and food scraps. If every household would do just these few simple and cheaper things on a consistent basis it would benefit us all.

Well is he saying it takes 2 Tesla Powerwalls to meet that extra power requirement 27 kilowatts Generac power wall has less because it's just one battery., no Generac had two batteries that power would be way more than a dual Tesla wall

Here’s a great video to understand about how Tesla’s Powerwall can actually output only 10kw/hr after a full charge. This is with two powerwalls capable if producing 27kws. This guy has a massive house with a massive load of about 51kws/hr. The rest must cone off the grid. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Qgv6Lgvy8Lc.html

This technology is coming very soon. Ford already announced this capability for the new electric F150

Thanks. We are here to help when the time is right!

Glad it was helpful

@@SolarSurge especially appreciated the ac coupled dc coupled discussion, I didn't have a good understanding prior 🙂

Thanks for the feedback. We will continue too follow all of these rapid developments.

Glad it was helpful. I should mention that the backlog on Tesla is 12 months now, so if speed is an issue, I would recommend Generac.

Yes the Tesla Powerwalls are the most widely compatible for installation on existing solar PV systems. Let us know if you need a quote.

Hi Charlie and thanks for writing in. We have Powerwalls available for add-on to existing solar PV systems. Please use think link to book an appointment and one of our designers will help you out... calendly.com/solar-surge-sales-team/solar-consultation

They are telling us 4-6 months delivery time for new Tesla battery orders. Generac PWRCell batteries are shipping in 4-6 weeks.

Both of these battery systems support by directional charging/discharging

Since its AC coupled, it doesn't need a generator input. The real issue would be the lack of ability to tell it to charge when the generator is on and the grid is offline (as non-PV charging is only available during a Storm Watch NOAA-advertised storm)

@@rickkay9548 tesla Powerwall has the opinion to use it only for power outages you can set aside a portion or the full battery for a backup 😉. I own 2 Powerwalls never had a problem when the power goes out. No need for a generator.

Yes what you are describing is possible. Here, please use this link to book a virtual meeting so that we can discuss your project in more detail: calendly.com/solar-surge-sales-team/solar-consultation

Yes. Good feedback. The Tesla batteries can be added to your existing micro-inverter system. Generac would require a complete re-installation from the roof all the way down. Tesla is the better choice for adding on battery backup to an existing solar system.

@@SolarSurge absolutely right Tesla is a way better more intuitive system 🇬🇧 that integrates freely into any setup.

No, the Tesla Powerwall is much cheaper. Generac has quoted $10k for the 3 cell version. A Powerwall is $10k installed. A second Powerwall is only $5k more for 26 kWh while the Genrac is $20k for the 20 kWh version.

Yes, Tesla Powerwall can be used to form a micro-grid with an existing SolarEdge 7600 inverter.

Yes the tesla battery back up is compatible with span

Gyll is good for DIY projects. For a professional installation with a warranty, I recommend Tesla, Enphase, or Generac.

@@SolarSurge they do have a 10 year warrenty though. Why not have a installer use them? Is it because it has to be rack mounted in a 16u server to a wall like a home network center. Or is it because it's a code issue?

@@polarbearigloo It's a matter of installer confidence. Our installers provide a 25-year warranty on the system installations. If anything malfunctions, it's the installer who will have to provide primary warranty service, regardless of the manufacturer's warranty. Perhaps in a few years, installer confidence will be higher in these new brands.

Both of these systems are expandable but you will have to stick with a single brand. It is not possible to mix Generac and tesla batteries in the same system.

I mean you can mix these systems. Just not in a way that can communicate to one another right now. If you want a custom solution you may need to rewrite the firmware (obviously void the warrenty) and make your own communication bus for each charge curve. I would recommend a smart panel if you go mixing systems.

Yes, you can see the single block comparison here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tJMZwbrQkJg.html

I would look at LG, Qcells, or SilFab.

Q cell* best bang for the buck*

@@GeraldPUR Jinko tiger type N is by far the best bang for buck without a doubt

@@chefgav1 I'll check it out. Thnks

@@GeraldPUR very very close to same efficiency, temperature coefficient of LG and sunpower and warrenty but half the price. It's half the price here in Australia shouldn't be to much different. Jinko is the largest solar manufacturer in the world

That would not be practical for these batteries. Most wind turbines have their own DC charge controllers that work with 12, 24, or 48V batteries.

I don't recommend wind turbines. If the past, I've done hybrid wind/solar off-grid systems and they are always a disaster when it comes to maintenance.

@@SolarSurge i know the maitence diff, but in my city theres 365 days a year 4m/s wind and max 30days of sun. So im looking some urban system that have smart switch to power my household and at same time deliver power to crity grid when owercharging. Something like tesla wall

I do agree with you Sir. Plus ..i think the generac will be the better option if i wanna go full Offgrid

Cool marketing, but truly no magic here. Ecoflow is over priced relative to cost per kWh.

Yes, 2 PWRCell inverters and 2 battery cabinets can be combined.

Hi Jack and thanks for writing in. The Powerwalls come with integrated inverters for backup mode. There is no need to purchase a separate hybrid inverter.

จ

Where is this neighborhood microgrid in use now? My guess is that it’s a bunch of baloney!

@@jesse1441 A suburb in the city of Adelaide in South Australia was the first, connected to the Hornsdale Battery Project.

@@wattlebough I was thinking of here in the US

Most level 2 EV chargers will pull 6,000W. A level 3 rapid charger can pull over 9,000W.

Hi Dennis. The 7.6kW/9kW peak refers to a single Tesla battery. So for 2 Tesla batteries, the total system would be 15.2kW/18kW peak.

@@SolarSurge Thanks. I understand that the single Tesla system is 7.6/9 kW, but I thought that the comparison that was being made in the video was between the dual Tesla system (not the single) versus the six battery single panel Generac system. I now see where when you mention that Tesla upgraded to 7.6 and 9 kW on the battery module, you were talking about the single system not the dual system. Again thank you for your response and clarification.

We can help you add storage if needed. Please use this link to book an appointment: calendly.com/solar-surge-sales-team/solar-consultation

Yes, that's possible, but it would void the Tesla warranty.

Web access does not matter whatsoever, its only used for uploading data and showing status on the app etc - it still works regardless and will not shut down. You can also still access it over your local wifi network. During the Texas storms, my modem was up, but the network outside my house to the ISP was down, and power was still completely uninterrupted.

There'd be no market for the Tesla Powerwalls if they stopped working when the grid went out, that's the whole point of them

I agree. Joe shows at 2:03 in the video a comparable system cost from S.S. for 17 kW solar with 1 Powerwall is $44,667 + $10,500 or $55,167 before incentives. Looks like you need to give Joe a call at S.S. for a comparable quote!

@@a07866 S.S. doesn't do Michigan. Crying face. 😢

Yes Enphase would be the third option here. However, for a whole house backup, you would need at least 3 Encharge 10 batteries. Very expensive compared to Powerwall or Generac.

I have an Enphase system with one Encharge 10. I’m powering everything except my HVAC and it does what I need. It powers my whole house when the power goes out, which happened on Wednesday.

We can probably beat that price for either of these configurations.

30k for Tesla battery?

You might want to approach a licensed electrician and ask them to approach TESLA. This could speed up Tesla's approach to finding licensed electricians.

?????????? WTF!!! ???????????

I would recommend Generac for 100% off-grid operation. The Generac system is DC-coupled which allows for more efficient battery charging.

Yes we have Tesla batteries available as an add on to non Tesla solar

Although Tesla no longer offer battery-only installations, we can perform that service for you.

Sure, we did that comparison here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tJMZwbrQkJg.html

About $25k over the base price of a solar system.

@@SolarSurge wow already a lot better than 2 years ago. Problem for me are the high taxes in Europe. In the other hand break even is a lot earlier at 40ish us$cent/kWh... 🤔

That’s true tesla will not offer you the battery directly. However you can buy them through third-party partners like us.

Hi Mike. We still have Tesla Powerwalls available for purchase with or without solar.

Actually, it probably won’t last longer. These batteries could last 20 yrs. with zero maintenance. No need to worry about fuel, oil, spark plugs, or maintenance. Sure it’s more expensive, but it’s worth it for many to not have to worry about the noise or pollution. The battery response times are so fast that you would not even know the power went out.

@@TecnamTwin Thank you for your reply most modern generators also have built in battery packs now days and can run on gas and are extremely quiet adding more nails to the solar panel coffin.
