| |
|
| |
| *'''Requires app download:''' To have full use of functionality and features, the customer [[Forced app download|must download]] the Tesla application.
| |
|
| |
| *'''Requires account:''' The product must be registered to a Tesla account.<ref>{{Cite web |author= |title=Registering Your Powerwall |url=https://www.tesla.com/support/energy/powerwall/own/registering-your-powerwall |website=[[Tesla]] |date= |access-date=21 Dec 2025 |url-status=live |quote=To complete installation of your Powerwall, you must register it to your Tesla Account and connect it to your home Wi-Fi network.}}</ref>
| |
|
| |
| *'''Always online:''' The product itself does not require internet connectivity ''per se'', but certain features will not be available. More notably, it is stated in the limited warranty agreement that failure to register and connect to the internet will greatly decrease the duration of the warranty.<ref>{{Cite web |author= |title=Tesla Powerwall Limited Warranty (USA) |url=https://energylibrary.tesla.com/docs/Public/EnergyStorage/Powerwall/General/Warranty/en-us/Powerwall-Warranty-EN.pdf |website=[[Tesla]] |date=13 Nov 2025 |access-date=21 Dec 2025 |url-status=live |archive-url=https://web.archive.org/web/20251221223944/https://energylibrary.tesla.com/docs/Public/EnergyStorage/Powerwall/General/Warranty/en-us/Powerwall-Warranty-EN.pdf |archive-date=21 Dec 2025 |format=PDF |page=5}}</ref> This effectively "encourages" the customer to always be connected so that Tesla Energy can remotely push firmware updates.
| |
|
| |
| *'''Arbitration:''' Agreement includes usage of [[Forced arbitration|mandatory arbitration]].<ref>{{Cite web |author= |title=Tesla Powerwall Limited Warranty (USA) |url=https://energylibrary.tesla.com/docs/Public/EnergyStorage/Powerwall/General/Warranty/en-us/Powerwall-Warranty-EN.pdf |website=[[Tesla]] |date=13 Nov 2025 |access-date=21 Dec 2025 |url-status=live |archive-url=https://web.archive.org/web/20251221223944/https://energylibrary.tesla.com/docs/Public/EnergyStorage/Powerwall/General/Warranty/en-us/Powerwall-Warranty-EN.pdf |archive-date=21 Dec 2025 |format=PDF |page=3}}</ref>

| *'''Market control:''' As of the quarterly financials for Q3 2023, Tesla Energy had an approximately 50% capture of residential energy storage market in the United States of America, with the closest competition being roughly equal between [[LG]] and [[Enphase]].<ref>{{Cite web |last=Issokson |first=Max |title=Which installers and battery vendors top the US distributed solar-plus-storage leaderboard? |url=https://www.woodmac.com/news/opinion/installers-battery-vendors-us-solar-plus-storage-leaderboard/ |website=Wood Mackenzie |date=12 Dec 2023 |access-date=21 Dec 2025 |url-status=live |archive-url=https://web.archive.org/web/20231214140753/https://www.woodmac.com/news/opinion/installers-battery-vendors-us-solar-plus-storage-leaderboard/ |archive-date=14 Dec 2023}}</ref> <!-- Really need to find more recent figures since Elon Musk's political adventures with Donald Trump. -->

| On 16 September 2025, the Australia Competition and Consumer Commission published a notice that Tesla was recalling affected Powerwall 2 units due to "certain lithium-ion battery cells from a third-party supplier in a subset of Powerwall 2 systems that may fail and overheat".<ref>{{Cite web |author= |title=Powerwall 2 | ACCC Product Safety |url=https://www.productsafety.gov.au/search-consumer-product-recalls/powerwall-2 |website=ACCC |date=16 Sep 2025 |access-date=21 Dec 2025 |url-status=live}}</ref><ref>{{Cite web |last=Lambert |first=Fred |title=Tesla recalls Powerwall 2 over battery fire risk |url=https://electrek.co/2025/09/16/tesla-recalls-powerwall-2-over-battery-fire-risk/ |website=electrek |date=16 Sep 2025 |access-date=21 Dec 2025 |url-status=live |archive-url=https://web.archive.org/web/20251222005829/https://electrek.co/2025/09/16/tesla-recalls-powerwall-2-over-battery-fire-risk/ |archive-date=22 Dec 2025}}</ref>

| A recall was issued two months later by the United States Consumer Product Safety Commission, on 13 November 2025, due to the same concerns.<ref>{{Cite web |author= |title=Tesla Recalls Powerwall 2 AC Battery Power Systems Due to Fire and Burn Hazards; Risk of Serious Injury or Death |url=https://www.cpsc.gov/Recalls/2026/Tesla-Recalls-Powerwall-2-AC-Battery-Power-Systems-Due-to-Fire-and-Burn-Hazards-Risk-of-Serious-Injury-or-Death |website=CPSC |date=13 Nov 2025 |access-date=21 Dec 2025 |url-status=live}}</ref>
| |
|
| |
| In both cases, Tesla had also pushed a remote update to affected Powerwall 2 owners that limited or drained the batteries and disabled its ability to recharge.<ref>{{Cite web |author= |title=Tesla Powerwall 2 Replacement Program |url=https://www.tesla.com/support/energy/powerwall/own/powerwall-2-replacement |website=[[Tesla]] |date= |access-date=23 Dec 2025 |url-status=live |archive-url=https://archive.is/dBLDf |archive-date=14 Nov 2025}}</ref> <-- The timeline is very confusing here. Did this happen first before any recall? Google-fu may not be strong enough here.

| A class-action lawsuit was filed 26 November 2025 in Florida by Arthur Brown, an owner of a Tesla Powerwall 2 unit.<ref>{{Cite web |last1=Brown |first1=Andrew |last2=A.
