Installing 21,000W solar array with 3 Tesla Powerwalls 3. Full home battery backup.

[@calimolotov2000]

Wonderful videos. Really appreciate the information you offer! Thanks

[@Jade0ryan]

Much respect for the details and hardwork 👊🏻

[@soulkeeper514]

Saludos desde Puerto Rico , good installation like always .

[@gojeffgordon24]

That is a lot of work for a 1-2 person crew! I had about 6 guys at a minimum and it was just a 24 panel install on 3 sections of the roof and no battery. They had to drive nearly 3.5 hours to get here so I'm sure finishing in one day was their goal.

[@SolarEngineering]

yeah, 4 days just one person + 2 days 2 of us.

[@solargoat]

Love this video.

[@SolarEngineering]

Nice to hear from an industry colleague!

[@MikeMoraCalifornia]

Unless you are mining crypto this is far more power than is needed in an average residential dwelling. I may have missed the details on this home.

[@nicksgarage2]

That's a lot of panels and powerwalls for that size house. My utility wouldn't let me put on that many on my 3000 sf house.

[@SolarEngineering]

interesting, not an issue in my area

[@nicksgarage2]

@@SolarEngineering Looks like they dropped the cap here with SDGE when they changed the net metering. I'm getting two Powerwall 3s installed today onto my existing system. I had a 10 panel Enphase based system and a newer 27 panel SolarEdge system. Removing all the inverters and using the PW3 ones instead with the backup switch and no gateway.

[@SalvaGer-bs4zw]

Very nice, thanks for sharing that! What specs are for a panel, how many watts and kg? Also, 9:30 mounting the powerwalls, isn't that too close to the ground? Mainly because of rain or even flooding, sometimes. Or snow, during winters. But it depends on the area, of course.

[@SolarEngineering]

powerwall can be submerged into water at the level where red cap installed at the front. It's fully sealed below this level.

[@JMR-d9h]

Thank u for sharing! Just a real quick question,did you encounter any difficulties during the installation process? What aspects do you think Tesla can do better to help you better install? Thank u!

[@SolarEngineering]

all straight forward. maybe I'll shoot a video of things that can be improved

[@AlsinoFerreira]

😎

[@dexmagpantay9849]

Nice video and install is there a Tesla gateway required for this installation?

[@SolarEngineering]

No, We need a gateway only for 400A service.

[@dexmagpantay9849]

@@SolarEngineeringthanks for your response. In Australia we need the Tesla gateway for every PW2 or PW3 install, we can’t install without it

[@mahdikhavari4312]

Nice installation. I think two powerwall3 were enough for 21kw solar panels

[@SolarEngineering]

we are in area where utility don't pay much for exported energy, so owner wants to maximize self-consumption.

[@DeathbyKillerBong]

not only am i impressed by your workmanship seemingly all alone (one helper?), its interesting to see how different things are in another nation

[@solargoat]

Nothing wrong with working alone. It’s lonely at the top 🐐

[@fpvclub7256]

Why 3 Powerwalls rather than 1 Powerwall and 2 expansion units?

[@SolarEngineering]

Expansion unit is not available yet

[@ThomasYang-w3y]

Is there a minimum distance you need to place powerwall from main panel?

[@SolarEngineering]

no minimum, just follow tesla clearance around PW.

[@mynameisZhenyaArt_]

HI, How did you learn all this?

[@SolarEngineering]

Tesla has a nice KZbin channel: @tesla_one

[@raulrse]

What's the best way to mount solar panel on spanish tile roof, if any?

[@ssoffshore5111]

Ground mount! 🤣

[@MichaelrennieG]

I hope they find that metal knockout that went flying inside the powerwall. looked like it could possibly short out the unit when they turn it on..

[@anthonyc278]

I have a question. Shouldn't the ESS be located at least 3 ft from the other powerwall?

[@SolarEngineering]

Tesla has UL9540A certification, that allows to install less than 3', however some AHJ still not allows to install less than 3'

[@W122ard1]

Why ppl choose tesla? Looks like that using good equipment but not from tesla you could do same system but at least 30% cheaper, no?

[@SolarEngineering]

I think it's about same price (if we compare same wattage and capacity). Tesla is easier to install (aka less labor expense)
