Just signed up w/Tesla for PW3 and 2 expansion packs with meter collar (Backup Switch), load center panel and a concrete pad to hold them - $29K. I get $7.8K rebate from my local energy company for the batteries, so drops my cost to roughly $21K. Less 30% Fed tax credit and should be ~$15K net cost for 40.5Kwh storage. I was going to go with EG4 BESS, but the Backup Switch eliminated about $5K in labor and significantly sped up installation, so I went with Tesla (gritting my teeth - think Musk is an first class tool)
Musk has had no hand in designing or building these batteries, the engineers and manufacturers did. Our daily purchases benefit any number of billionaires on a daily basis, no need to worry about it.
I have watched several Powerwall 3 videos and all of them have speculated that these are Lithium Iron Phosphate but no one has come out and said it or shown the Tesla documentation on the chemistry. Is it Lithium Iron Phosphate or not?
I do love the Delta pro ultra style one cable to connect them but that being said I also wish there was a internal connection port as well so that if you wanted to run direct from battery to battery when they're stacked on top of each other there was no external wires or if you wanted to run clean with conduit inside of a wall two batteries next to each other on the wall again you would be able to do it without a single wire showing
Excellent presentation and information. just put a new power wall three in yesterday. Waiting to energize it. I was just wondering with my 5.3 kW system would I have enough output to recharge 26 or 27kW if I put an expansion pack on my existing power wall.
It will depend on your average daily energy consumption. a 5.3k system should be able to recharge 2 Powerwall 3's if all the solar generation goes to the battery. However, if the house is pulling energy as well, then you may need more solar.
Looking forward to seeing this compare to the other batterie manufacturers, like Franklin and Enphase, and see how they stack up against each other. the meter ring I believe Enphase has now also, and those appear to change the installation elements a lot with both manufacturers.
Nothing changes on the DC solar input side. But on the AC coupling side you go from 7.6kW to 10kW of AC coupled with a DC battery. You can also DC and AC coupled at the same time. Nothing on the market can compete with the PW3. Nothing.
Forgot to mention that TESLA allows a 1.7 DC to AC ratio so you can install 19.55 kW of DC solar together with 7.6kW or 10kW of AC coupled solar. If you have a TESLA string inverter in the AC coupled side there is NO kW limit.
I currently have a 14.6 KW roof mount solar panel system that is controlled with all Solar edge equipment. I have no battery back up and do receive 1 for 1 net metering. The question is would I be able to add a power wall 3 dc backup or power wall with the solar edge equipment?
Since you have SolarEdge inverters on your system, you would need to install Powerwall 3 using the AC-coupled configuration. That would require you to install a Tesla Gateway 3 device. Or you could use another AC-coupling battery like FranklinWH.
@@SolarSurgeIsn’t there a 10kWatt limit for AC coupled solar attached to a single PowerWall, meaning a 15.6kWatt solar system would need 2 PowerWalls to accommodate rated power?
Not sure if this is the right spot to ask this. Got a quote from McCormack (18,700$ for a partial whole home. State it’s a 20hwh battery. Any way you can review there product to see if it’s worth it. Please.
Yes, PointGuard just notified me about a number of enhancements. The biggest is the bi-directional EV charger which should be available in the US in the next 2-3 months. PointGuard will also have a meter collar adapter soon.
YES Anything to keep your crap off the grid more batteries please Best solar is raising everybody's electric bills more batteries equals less on the grid and lower everybody's electric bills
Agree 100% the others are way behind on all level's power output, adaptive design and scalability etc. EG4 is taking over the market big time, many installers using them now.
Yes we are hearing reports on long wait times for Tesla batteries. I'll be coming out soon with a top Tesla Powerwall alternatives video for those needing a solution in the short term.
Tesla is on par but not cost effective or innovative. Just a big name people are growing to hate. I have installed almost everything on the market all the way back 20 years and right now EG4 is it.
Nothing against EG4 but most of their inverters are just rebranded Lux power. EG4 doesn’t have bidirectional EV charging, a charge on solar feature for EVs, or a meter collar. The Sol Ark EG4 drama was entertaining though.
I like that EG4 is pushing the market, and the GridBOSS/FlexBOSS combo is interesting. But a relabeled system with immature firmware… not so great. And makes likelihood of multi-vendor bi-directional EVSE support seems like it could be a ways off (I’m aware such standards not yet finished/published in North America). But firmware and support issues with EG4 are well-documented in Will’s DIY solar forums. No meter collar support? Show-stopper for me. And some other important features others have mentioned. So, I look forward to the competition and for now, I’m holding off on a whole home ESS (a retrofit, so it will be AC coupled, so MPPTs on PW3 are wasted on me, UNLESS it supports and is certified for CA non-export expansion option in CA (to stay on NEM2).
EG4 is garbage. The comms on those suck and a good chunk of the time they will drop when connected to their OWN inverter. Then the EG4 equipment is a much worse price than building your own pack (at 1/3 the cost!) or even compared on the inverters EG4 makes which are STUPID expensive. I can get an inverter at almost DOUBLE the output for the SAME cost that parallels A LOT easier than the stupid EG4 inverters. Only a complete useless idiot would suggest EG4 as a replacement for Tesla equipment.

Is it installed cost or just parts ? Thanks for the info in advance.
What about the panels?
Musk has had no hand in designing or building these batteries, the engineers and manufacturers did. Our daily purchases benefit any number of billionaires on a daily basis, no need to worry about it.

@1:43 the pictures shown 1-2 connect and 3-4 connect where 2-3????

I will do a comparison video soon, showing how this new Powerwall 3 DC Expansion Pack compares to other batteries from Franklin and Enphase.
Would love a video explaining powerwall 3 solar input Mppt limitations and if anything changes when adding a extra battery or two
That’s a great suggestion for a video. I'll work on this.

Really hoping Tesla and EnPhase work out better PV curtailment approach vs frequency shifting

The question is would I be able to add a power wall 3 dc backup or power wall with the solar edge equipment?

@@SolarSurgeIsn’t there a 10kWatt limit for AC coupled solar attached to a single PowerWall, meaning a 15.6kWatt solar system would need 2 PowerWalls to accommodate rated power?
Yes he needs two of the 11.5kW PW3’s AC coupled.

Is there anything new about point guard battery storage
Yes, PointGuard just notified me about a number of enhancements. The biggest is the bi-directional EV charger which should be available in the US in the next 2-3 months. PointGuard will also have a meter collar adapter soon.
I keep waiting on V2H.
What’s V2H?
YES
Anything to keep your crap off the grid more batteries please
Best solar is raising everybody's electric bills more batteries equals less on the grid and lower everybody's electric bills
Who using 30KW a day in energy 😮. We use 10KW on average a day and thats a family of 4 and two work from home.
Still disappointed that two PowerWalls can’t each accommodate up to 3 expansion packs for a total of 8 (2x4) batteries worth of storage.
Not sure anyone buys a Tesla in 2025 forward 🤷♂️🤷♂️
Boycott billionaires
Rebrand Incoming. Tesla White Power Wall.
Not worth it z eg4 batteries and system
Much better and cheaper
Agree 100% the others are way behind on all level's power output, adaptive design and scalability etc. EG4 is taking over the market big time, many installers using them now.
Lol 6-7 months out for batteries not including techs for services
Yes we are hearing reports on long wait times for Tesla batteries. I'll be coming out soon with a top Tesla Powerwall alternatives video for those needing a solution in the short term.
Tesla logo replaced with a swastika. Can't unsee it🙈
Musk isn't coming to your house and installing the batteries 😆He owns the company, he didn't design the product.
Tesla is on par but not cost effective or innovative. Just a big name people are growing to hate. I have installed almost everything on the market all the way back 20 years and right now EG4 is it.

The collar install is the only reason I went with powerwall.
