Tesla Powerwall 3 Vs Franklin Battery 

Good comparison, but not seeing how Franklin is an easier install than Tesla. Several items missed here, including that Tesla also has the drill assisted dolly. But more importantly, that many jurisdictions allow the Tesla Backup Switch meter collar to be used - greatly simplifying whole home backup installation with no service/feeder wiring to redo or transfer switch to wire. So install should be the same or better with Tesla, and X-factor point given for that - not to mention it has an impressive 6 MPPT channel solar inverter in the unit. And Tesla can AC couple to other solar also - if you don't want to do that. Also would like to see mention on how you can parallel 4 units, and/or add more battery capacity to a single unit - and how that compares to Franklin.

Tesla also has a battery lift system 😊

Great job on this Analysis. I have been looking for someone to explain the difference between these two options and you did a great job. Thanks!

I have been waiting for that comparaison for so long! Thank you!

I would like to see a video on Savant battery, the ins and outs, the full lineup of their home management, pros and cons etc. love the content on this channel! Thanks

I like the idea of a DIY battery system like a Canadian Solar EP Cube or an Ethos stackable battery system that has stackable individual battery packs with an inverter control system. One person can install it themselves or with the help of an electrician to wire it in and years later if one of the small stackable battery packs goes bad they only need to replace that one cheaper bad battery pack instead of needing to buy and replace an entire Franklin or Powerwall unit. You can also add more stackable battery packs to increase your storage capacity instead of having to buy another full sized Franklin or Powerwall unit. Stackable battery units also take up less wall space !

I think a good x Factor category here would be support.

Always great content. Thank you! I'd like to see you spend some time on EV/bi-directional charging!

When we spoke in December, you weren't to keen on the Franklin, due to integration issues. Has things gotten better in that regard? As for installation, if your utility allows the use of the Tesla backup collar, that saves installers hours of time!!

I have a generator(generac) and am interested in adding solar down the road. I would be interested in hearing what my options are.

I prefer Storz Power coupled with the Sol-Ark 15 kW inverter.

Just installed 2 pw3s in my home and the install couldn't have been easier with the telsa lift and integrated/pre-wired inverter. I would rate install a 5, telsa really did make this very easy for installers. Also the seamless app integration with my existing ev wall charger and telsa car works great and worth at least another x factor point.

I just signed up to get two Powerwall 3s using the backup switch. I have two separate existing solar systems, one with Enphase IQ7s and one with SolarEdge inverter. All the old inverter components will be removed to use the built in inverters. Will greatly simplify my system and after having two SolarEdge inverter failures over 6 years, I'm hoping for a more reliable simple system and whole home backup including a/c.

I am looking at putting a solar system in using the Tesla power wall three battery. I have an existing Generac 16 kW generator that’s 20 years old. It has its transfer switch with its panel.. what I plan to do is run my critical loads off the generator panel. The Tesla battery will supply the main panel which will supply the generator panel. in a power outage, the Tesla battery will take over. if the Tesla battery becomes low, I could start the generator and run the critical loads. When Solar comes back, I could switch over to the Tesla battery. Unfortunately I will not be able to charge the battery from the generator however, in time, I’m I hope there will be a device that you can to attach to the battery to enable this to happen. Thank you for the comparison. do you know what type of lithium ion batteries are used in each battery?

What other solutions do you see for generator integration? Like the Tesla but, it only works for one charge, then you are on genset only.

I'm looking to start with the batteries before going solar. My roof is 8 years old, and I don't want to install the solar panels then pay to have them removed when I have to replace the shingles. I also will fight the HOA to get a metal roof on before going solar. I plan to use the batteries for my whole home during the day, and switch to grid at night allowing the batteries to recharge. I like the idea of having a generator to recharge the batteries should the grid go down. Does the Powerwall 3 not allow for a generator to recharge them? Thanks for the response.

Should you install a soft starter on the hvac ac unit to help the battery with not discharging so much energy if you only have 1 battery instead of 2 ?

We have a powerwall 2 (actually 3 of them). Either now or later can we add more battery? Preferably Tesla, possibly other. Our inverters are APSystems DS3, and we use the Tesla Gateway. The electric power company is our 'backup'. Here in Clarksville TN we can sell some excess power for about 1/3 of the cost of power.

I have 24 panels on my roof that all work with the in phase 7 inverters. I don’t want to be forced into nim three but I would like a battery for storage if shit hits the fan. What should I do and where should I go?

Great video. I would like to see a comparison between a portable solar generator vs. a home battery. For example, Eco Flow Ultra vs. FranklinWH or Tesla. I don’t know if you work with portable batteries. Thank you.

Where I live I have 5-6 power outages from my supplier PG&E and these last for up to 5 days. Having one day of battery backup power is a bad investment. I put my money into a natural gas standby generator that can run for months with no issues.

Joe, great comparison! Can you do a comparison with the Franklin & EG4-WallMount Indoor Battery | 48V 280Ah | 14.3kWh | Indoor | Heated UL1973, UL9540A | 10-Year Warranty?

What is your opinion on the Midnite Solar Rosie 7048 inverter?

Joe, can you review the Ethos Battery Backup System with Solar... The price is off the chart good and I want to know your take on this.

These scoring break downs done here show where the bias is. If one system puts out a continuous amount of power that is more than double the other there is no way that only a one point difference. Also installing one piece of equipment that's lighter than the other one should be easier than installing two pieces of equipment that's heavier and takes up more space. Which explains the cost of installation difference. Why would it cost more if it's easier. Make this makes sense. ANYBODY

I currently have 52 Sunpower 330w panels and 2 Tesla 7.6 kw inverters. I’d like to get backup power added. Like the Franklin whole home.

No mention of the use of PowerShare if you have a CyberTruck which almost 10 times the battery capacity.

In Connecticut, the powerwall does not qualify for the upfront battery incentive through energy storage solutions making it more expensive than the Franklin in my case.

So I think you missed some x-factor. The Powerwall’s power switch is worth at least 2 if not 3 points. It’s easy to install, it’s cheaper than any other switching system and coupled to the power wall it allows you to put a 60 amp breaker in a 200amp breaker box.

Neither both are junk and way to expensive. I just added to EG4 wall mount batteries and got 28.8 KWH for 8 Grand. And peform way better then both and i got a15 year warranty

Tesla 3rd party is a complete hassle & expense to deal with in Oklahoma. Tesla needs to sell the batteries separate from a dealer…

I came for actual prices, feeling let down

I think one X-Factor you missed for the Tesla is in some areas of the country the system can participate in the VPP programs. I have a SunFusion Energy storage system DC Coupled with Sol-Ark inverters. I am working on installing a generator input on my battery cabinet so I can if necessary charger my batteries from a generator. My house is on Propane so I plan on just using a propane powered generator for this.

Chemistry? Is the difference in safety and cycle life significant?

Why not just use smart outlets for any non essential loads? 100% granular and far cheaper than a new smart panel plus installation. Also, twice the power is only worth 1 point for Tesla and the integrated inverter should even out installation ease.

UPDATE. I erred, the PW3 CANNOT be used with Enphase IQ8 inverters. I stand corrected.

Both systems should be installed outside of the building envelope as they produce toxic gases when they catch fire.

I am not sure that the Tesla Powerwall 3 is such a great bargin, even when ignoring the fact that it is designed only for a main string inverter type of install with no panel-level optimization and no panel-level monitoring capabilities. From an NEM 3.0 self consumption effectiveness point of view, as well as being able to sustain longer than 1-2 hours of a power loss period for the backup use cases, Tesla's Powerwall 3 13.5 kWH capacity with its continuous 11.5 kW power ratio doesn't give any advantage. The continuous 11.5 kW power sounds more like a marketing story than an actual benfit. It doesn't make any sense to install a single PW3 when a continuous 11.5 kW power is needed, since a continuous consumption of 11.5kW will drain an entire single 13.5 kWH battery within 70 minutes (one hour and 10 minutes). This means that a useful whole home install will require at least two batteries, if not three, because of the capacity needs. Given that, the Franklin's 13.6 kWH capacity and continuous 5 kW power ratio makes much more sense as a building block, since it will take 164 minutes (2 hours and 44 minutes) to completely drain. From here we can do the math: - A single FranklinWH battery: up to 5 kW of continuous power for at least 2 hours and 44 minutes. - Two FranklinWH batteries: up to 10 kW of continuous power for at least 5 hours and 28 minutes. - Three FranklinWH batteries: up to 15 kW of continuous power for at least 8 hours and 12 minutes. Given the need for multiple batteries for any NEM 3.0 practical self consumption and backup use cases, and given that the collar approach is not applicable for an install of more than a single PW3 battery, the Tesla Gateway along with an extra Critical Load Center Panel are also required with a multi-battery install, which blows away the theoretical cost advantage of a single Tesla Powerwall 3 with a collar install connected directly to the main panel. Also, based on the fact that the Tesla Powerwall 3 with its internal built-in inverter(s) is more than 100 lbs lighter, as well as smaller in dimension compared to the FranklinWH LFP based battery, it is highly unlikely that the Tesla Powerwall 3 chemistry is LFP based. Most likely still the older and less efficient and safe NMC based, like the Powerwall 1 and 2.

So I use my AGate generator circuit to connect to my F-150 Powerboost. A full (29g) gas tank gives me about 233 kw/hrs at 220v/30a. And I can leave for a few days if I need to hunt up some gas :). Apocalyptic scenarios aside, I really like the system, it gets me the best of micro-inverter, black start, generator support, and load shedding all in just 1 box plus batteries. Cost-wise, I feel like it’s still competitive if you want those features. The tesla would still need a Span smart panel for shedding and a generator failover controller. And at least 2 if not 3 apps to run it all. Now if I had a Cybertruck, the built in integration would make the powerwall a no brained, but outside of that, I think FranklinWH is still a better deal.

I would give Tesla a 5 on capacity and Franklin a 3. On installation, I would give Tesla a 5 and Franklin a 3. There will be less switches with Tesla, plus no inverters on the roof and I go DC to DC. This makes Tesla better for efficiency.
