Didn’t solar edge just go bankrupt?

DC on my roof is a no-go. PW3, make it AC coupled and I will go with PW3

Why not add Tigo optimizers to the PW3 system? Thats not even $50 per optimizer and you would gain per panel monitoring and control? Would this work?

Absolutely no hidden features, just a scroll through the menu that is available for all to see. Waste of time!

Another great video. You have a knack for generating pertinent, understandable, and accurate information and presenting it is a highly understandable manner. I really enjoy your work. I also just watched your video from 2003 on the Schneider Home system with the Pulse, Inverter, Boost, X series modules and Home App (Wiser I think). As you recognize the details that Schneider had released back then were sparse. Now I understand that the Schneider Charge has been added and it can be set up to automatically charge an EV with unused PV power. And the Inverter can operate in backup, and probably other modes with automatic load control to make maximum use of the inverter's available output with available PV power, without overloading the inverter or the PV array. I think that would likely work so that you can make EV charging a priority or make grid sell a priority. Unfortunately, I can't find any details on this whole system. With the Wiser CTs on both the grid feed and the inverter feed to the Pulse panel that seems like a natural operation for the Wiser App. How about doing an updated report on the Schneider Home system and add in some details about how everything interconnects and the automatic load management capabilities?

Can you explain round trip efficiency?

Is the Enphase system priced with only one 5P battery? If so, it would be useful to price it with 2 5P batteries to more closely match the others. Total of 10kWh. For some reason your Enphase quote suggests it is a (1) 10kWh battery. "1 x [ESP] IQBATTERY-5P-1P-NA 10kWh".

I've been searching for this kind of content! Subscribed, and I'm ready to chase my dreams! - "Determination and resilience are the keys to success."

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.

As all BUILDING owners do what you say here, the GRID owners will want you to add more rooftop PV and have your BV selfplug-in V2G and have BUILDING owners supply the grid with excess electricity 24/7. The GRID owners can then connect new industrial heavy user customers to the existing grid and maintain cashflow. New GRID is incredibly expensive. Few people understands until the construction prices are provided for new grid projects. Unload existing building loads and take excess electricity and sell it to new industrial heavy users on the same existing grid. Just my construction decades experience. 😊😊

Did you say you warranty the battery and equipment for 25 years?

I don't think TEP has net metering. We pay about 15¢/kwh and they only pay us 6-8¢/kwh. I try not to send anything back to them if I don't have to. With 4 Powerwall 3's and 2 cars that can charge on solar, it rarely happens. I've even setup automations to pre-cool/pre-heat my house before sending it back, using the home as a thermal battery if everything else is full.

Where is the secret? ,

How do secure who you want to be?!! I like PoE wiring but it's pretty useless only for a specfic product and why in BMS systems I would like to make it easier.

Suggest parallel vs series Author of Solar Independent Utility Systems Manual online Nice production My last bought are Eco flow double sided Solar Sale for .64 cents a watt

Well done. Very clear and concise information!

Love both Powerwalls and generators, but the hard truth is if your primary goal is backup power then you shouldn't look into Powerwalls. The backup power is more of a "cherry on top" in the sense that while it can do it, it was never the main feature and primary reason you should get one. ~10 hours of backup power is fine for short term outages, not long term though. Powerwall's are mainly for selling / using energy during peak rates

A battery is better if you are looking to augment a solar installation or only have outages of a few hours or less. If you don’t have a solar array or are in an area where heavy snow and ice can cause multiple day outages, you will. be much happier with a generator.

You omitted two of the key differences. A generator can provide power for days on end. If you lose power for multiple days when it is cloudy or snowy, you are in trouble with a battery. And lifespan wasn’t mentioned. A generator maintained well with last 30 years easily. I have multiple prices of lawn equipment that are 35 years old and going strong on their original engines. A battery will be all but useless in 15 years or less. When you factor in needing to product 3 batteries for each generator, the environmental impact of the battery production is much higher than a generator.

The one advantage a generator has is that it can be refueled in a long duration power outage. The Powerwall will be drained in less than a day/night even with a pretty big solar array. And of course, the solar array doesn't help during stormy weather when the grid goes down. Yes, fuel storage (in gas cans) is a disadvantage of (portable) generators, but in theory, one can use the fuel being stored in a gasoline vehicle avoiding the need for gas cans. And the gas vehicle might make it to a different area for refueling.

How to turn on ???

Not only do modern panels negate a lot of the need for optimizers, but with the Powerwall3, you can split the panels into multiple strings, 6 per powerwall, so you can isolate the panels that are going to get shaded in your example. I just had two PW3s installed and removed my SolarEdge inverter as well as the microinverters on a separate older 10-panel system. Removed a lot of equipment and using the Tesla Backup Switch, I have whole house backup as well as backing up my separate workshop. I'll probably add more panels and the add-on batteries when they come online.

I see it’s just use for night tight use when no solar. Before sun comes up , generator turns off

I’ve got mines in place of my wired to replaced the electric company input and main thing is that your using inverter generator and the gateway can’t tell because it puts out the 60Hz that the electric company does.

From Tesla site Powerwall & Generators Powerwall can be added to a system with a backup generator connected with an external Automatic Transfer Switch (ATS) or a Manual Transfer Switch (MTS). Powerwall is installed between the utility meter and the transfer switch and can charge from solar while the grid is operational. However, the Powerwall and generator are not directly integrated which means Powerwall does not charge from the generator. In an outage, Powerwall responds immediately and provides backup power before the generator can detect the outage. The generator is turned on only when the Powerwall has low charge, or if loads exceed Powerwall's maximum output. When grid power returns, the generator will turn off and Powerwall can again charge from solar. If Powerwall is installed with a MTS, manual operation of the switch is required to power the home with the generator.

Can they hook up a generator to turn on manually or automatically when the powerwall gets low just to take care of the house load until the solar kicks on and charge the battery again.

Lift the battery with a portable motorcycle/ATV lift. You can go to Harbor Freight and purchase a riding lawn mower bracket and attach it to the lift. I am certain that it works because I just installed 2 Apower's 18"s off the ground bye myself.

Recently bought a solar system (without Power Wall) through a local installer and the system included this inverter. I cannot register the inverter through the Tesla phone app per the instructions on Tesla's support site, and Tesla Support refuses to help since the purchase and install was through a third party. Support told me that it's the vendor's baby to change, not theirs. I have started the dance with the 3rd party vendor, but so far I am extremely disappointed with Tesla.

I thought these were bifacial?

💯💯💯

Do you use bifacials, what do you like in that format? I ask because I’m considering a pergola carport (ChikoUSA has solar specific frame), which seems like a classic bi use case

Appreciate you walking through the details on this analysis

These are very impressive panels...but they also cost almost twice as much. You may have better prices as a distributer/installer. But I've seen Aptos panels go for $120 a panel on some sites (which are decent panels- maybe not as efficient- but when you are talking 1-2%+/- does it really make that much of a difference?)

Cross-check the net cost of the Jinko panel

Were you not able to use the collar/backup switch that installs on your meter?

Very informative comparison! Seeing a 40-year degradation is more interesting than the typical 25-30 year metrics we see

Well they filed Bankruptcy, now my app don't work. Any suggestions

Great job with these shorts / Good information

Dale, when will you be able to do the same in North Carolina?

So is it free estimates? or not. Im confused. I am in the market for a system exactly as you described in San Jose, CA

Hi Dale, just heard from our installer that REC Alpha Pure 420 KW panels are no longer being manufactured. Fact or fiction? Also spoke to their competitor and they said that the price is going up as of Aug 1 ‘24 but still very much available. Do you have any insight on that? Thanks a million on any info.

i just purchased a home with only 9 panels and when reviewing the daily production, i am seeing only 12-15 kwh per day, getting peaks of 17 kwh per day last month. in the video, the generation chart example showed daily production as low as 32 kwh and as high as 67. is this assuming the example house has a lot more panels?

Good solution pricing but I question the projected savings under NEM3. SCE's 2024 NSCR rates are a paltry $0.02-$0.03. A single 13.5kWh PW3, even if set to full DOD cycle, will not be sufficient for self-consumption. Daily production in good days is > 50kWh. So the customer gets credited pennies while billed > $0.25 TOU-D rates.

Dale, what about uses like me??? You’ve got my info can you let me know please 🙏🏼

Great information, Dale!

I want a system based on IQ8 microinverters because they're the only ones that can provide continued electricity to your home even if the grid goes down. I still don't trust batteries due to fire hazards. I feel even in an extended power outage the overnight down time will still be survivable.

How about Southern Arizona?

What I’m wondering, for those who are on NEM2.0 can they still be on it after getting batteries?

Did your install require steel bollards to be drilled into the concrete to protect the batteries? They are saying mine needs bollards to prevent a car from running into them. Maybe it’s just a state requirement on my end

Hello Dale, may God Bless and direct you in your new venture. All you have accomplished before, was just training for what you will be doing now. Do you remember my motto? "Nothing is impossible, it just hasn't been done yet and maybe you are one who is supposed to do it." 👍
