Absolutely genius idea but at the cost of between 6k and 7500 you could buy 2 of the EG4 14.3 kwh wall mount batteries and the lack of battery storage should be solved.

Man I love your videos! To hear someone who REALLY knows the specs, capabilities, and pros and cons of each battery system, with no bs, is really refreshing 👌 PW3 is a beast, for sure. Any word on when the dc expansion units are available, and also the remote meter system for the Gateway3, to allow partial home backup and sync with smart tarrifs? Keep up your videos, they are essential in the KZbin swamp of late. Cheers, Mick

Excellent video...I looked at your service area map. I'm in Georgia which you don't service....can you recommend anyone in Georgia given your years of experience in the business. Thanks

While I am in the beginning stages, I am impressed with the xxKpv line of inverters from EG4. However, I wish they would introduce a 6Kpv inverter, which would be sealed and have a 10yr warranty like the 12Kpv and 18Kpv instead of the 5yrs for the 6000XP. Why 6Kpv? I would rather have fault tolerance by using three 6Kpv instead of a 0-fault tolerant inverter system as with a single 15K or 18K model. Each 6K would have equal battery and PV allocated to them. If one were to fail--especially in the middle of harsh winters in NE OH, we could limp along at roughly 66% kWatt capacity (and could re-allocate the storage and PV to the operational converters until a later date.

Thanks , love the pointer

"Dragging the string down" is an old problem, i advice you to check this real test comparing the shading of panels. kzbin.info/www/bejne/iorSnGWaqdqMgbs

I wonder that it takes to back feed electrical power back to my house during outage with or without PW3?

New subscriber. Good analysis. newbie question: what is better a Enphase or a eg4 system (microinverters vs just one inverter)?

Good stuff.

Just finished a duel 18kpv system with a very clever propane generator setup and over 900ah battery bank and 7kw solar(so far). Very awesome 👌

Dropping knowledge like a boss!

Thank you for watching!

Can you use battery banks of 12.8V 280ah Eco-worthy batteries with the EG4?

Great video. Thanks. 👍

6:18 Gen input not suitable for smaller generators? Can you please elaborate?

All these inverters are made in China Sol-ark is made by Deye started in business in 2007 Luxpower is the manufacture of EG4 18kpv they started in 2017. US companies like Sol-Ark and EG4 slap a name on it and handle the US support. If you go to Deye's website see bunch of inverters that look like Sol-Ark have Deye name on it. The real savings is the battery EG-4 power pro and the EG4-18kpv have the UL9540A ESS certification at a far lower price then any of the competition. Now that many AHJ's are requiring 9540A prices of batteries were sent in the wrong direction shame that regulators continue to play these games for the utilities to keep solar expensive.

Looking at the battery spec I have to ask. Is 3.84 kVa same as 3.84kw?

Thanks -- this was helpful! And I know it won't matter for most people...but for us...altitude plays a role. The EG4 isn't spec'd over 6,562 feet (may encounter arc jumps on pcb traces and EG4 won't warranty.) Sol-Ark is 10,000 feet. We're at 8,100.

Good overview and thanks for correcting previous information, it takes a big man to do that! I'm in the middle of choosing between these two and the Schneider Electric's XW Pro. I see in their spec sheets and your white board that both of these units can handle 12,000 continuous watts (battery only, no PV) L-L @ 240V. I have seen or heard somewhere, but I can’t find it write anywhere that the EG4 18kPV can handle 8,000 continuous watts (battery only, no PV) L-N @ 120V either Leg as long as the combined is not more than 12K. Can you confirm this and site a written source? Also, I’ve asked Sol-Ark the same question but they will not answer the question. Do you know these specs for the Sol-Ark 15k? If not, can you point me to someone or place who can answer this seeming easy question to answer.

If there’s one thing I can’t stand more than anything else 😂 With a white board behind you😂😂😂😂😂 Can’t make that shit up😂

Had my Powerwall 3 for a week now. Quite happy so far

This guy in pajamas forgot to clean up and us not an authority on the subject.

Great info thank you

Thank You for All that you are doing for our Planet Earth.. .. Peace.. Shalom.. Salam.. Namaste 🙏🏻 😊 ✌ ☮ ❤

In NJ for install 4 5p batteries companies want 38.5k $ this insane. 2 tesla powerwall 3 cost 22k $. Same chemistry, more capacity and more output. One thing is different tesla powerwall 3 can not be charged from generator.

A great video, thanks for taking the time to put all of these new features and capabilities of the Powerwall 3 on a video. Perhaps the single biggest and in my view most important, features is that huge peak power capability. I live in the desert and have two AC units. For everyone else's inverters operating in backup mode, something has to be done to prevent the inverter from shutting down and going off line if both AC compressors start up at the same time, particularly if the OAT is over 100 degrees! I also have couple of quick comments / questions. On the mid circuit interrupters, in round numbers solar panels put out around 50 volts around midday, two in series output lethal voltage, so wouldn't the mid circuit interrupters need to be placed on each panel, not on every two or three? At least according to the Fire Dept. where I live there shouldn't be any lethal voltages when the system is in rapid shut down. You also said that you would have to buy enough Powerwall 3 units to power the whole home during backup. Doesn't it have any sort of load management / load shed capability? It seems that a good portion of the competing manufacturers either have automatic load management or are working on it. I would like to see another video on the Tesla App and in particular how it interacts with the Powerwall 3.

Great Vid ! Gracias Amigo !😁

Really enjoyed a lot of the points you made in this video. Enphase is gaining more and more popularity depending on what the individual's needs are. With the ever changing solar industry, it's not always easy to keep up with new trends and equipment. Very educational piece. Keep it up!!

How am I getting a Gateway 3 installed with my PW3 ? I have an existing system with a SolarEdge inverter and optimizers. They tell me it can be AC coupled?

I have 4 Enphase 5ps installed. Calling it good for the next 20 years assuming I live that long.

I just looked at Tesla website, if you go to buy a power wall it does not say definitively what power wall version you are buying. Anyone know why?

Great video. Thanks. 👍

Wow. Talk about major limitations. Not even compatible with there own older systems. Just a way to force you to buy more equipment exclusively from them.

Can we AC and DC couple at the same time? I think yes. What are issue will occure during the the setup? As DYI Trying to see what benefits for both system intergrated?

How about an install on a house that already has solar but no storage? Is there a way to install a PW3 so it charges off excess solar during the day and runs the house in the evening/night, without tying into the current solar system?

Very good video. Would be great if you can do more on microinverters such as install steps or components needed like dc/ac disconnect

wholesale sol-ark cost $5500

Nothing new, Tesla is just catching up to the competition.

I have been into Solar for Years and I am an EE. Some of these comments are just missing the point completely. This is about safety and what the inspectors want to see. It does not matter if your PV is limited to less than the Amps rating. It does not matter if your batteries are limited. Every Inspector knows that the Amount of Panels may increase and more batteries could be added later. They are only Interested in what is the Maximum the Inverter, Wiring and Panel box can handle when put together. This was a good video but could have been better if the Buzzer sound was eliminated.

I'm glad Sol-Ark has dropped the made in USA advertising. Also, I've seen too many vids of the Sol-Ark inverter being underpowered. I do like Will Prowse (sp) recent video of the EG4 12k showing the inverter able to start 4 compressors and a car lift without tripping the inverter. I'd love to see if the Sol-Ark 15k can do that. Also, pricing is a huge deal. Lastly, the ferrite filters they add to the panels as an EMP protectant I would have a hard time relying on. I would go with EMP Shield's products, it's much less expensive that paying to EMP hardening the Sol-Ark inverter and you can get all the proper protection for less cost, ie protection from the grid, the solar array and the battery.

I’m pretty sure Tesla has had a meterbase mounted Backup Switch for 2-3 years already. Is this Backup Switch you’re describing different from that one?

your talking solar not the inverter that is doing the dc to ac

Do you have a source for the 20,400 watt peak for the 18kpv, I can't find a source for that and having an official source for that would make permits much easier for a project I'm working on.

Where do you get that 10 second power number for the 18kpv? I've been unsuccessfully looking for an official source for a peak output as part of dealing with some compliance issues if I want my ac on it as I'd need the peak output to be above the lcked rotor amps of my ac. If there's an official source for that 20,400 number it will save me a lot of work.

Build Country of Origin for both...................CHINA

when the dc expansion packs come out, is it possible to add just that to enphase panel system ? or do we need the pw3 and the dc pack can only be added to an existing pw3 ?

Informative Solaredge Ecosystem. Nice work!

17:00 The Tesla backup switch, eliminates relocating loads to a Backup Load Center. If there’s not enough space in the main panel for the PW3 breaker a generation load center might be needed. 20:05 The PW3 can work with a Generac backup. Main panel, Gateway, Generac breaker in Gateway, then Generac relay, then Backup Load Center.

MAJOR PLUS for EG4 is that in can be installed right on top of the cable trough, because it does not have a requirement for any space at the bottom like the 6" for the Ark-Sol.

Unfortunately this data is still incorrect. The max usable PV of the 15k is 18kW (with batteries). Without batteries it's only 15kW like your whiteboard shows. The maximum continuous inverter output without PV is also not a fixed 12kW. The maximum DC discharge rate is 275A and the output is based on that. So lets say the batteries are currently at 52V, after inverter losses it'll be able to output around 13.5kW. The 18kPV has a 250A max battery discharge rate so the maximum inverter output ends up being around 9-10% less than the 15k at a given battery voltage.
