energy storage is becoming a lot more and a lot more interesting to smart home owners and we recently identified this write up of a Tesla Powerwall 2 installation on Michael Vorstermans Blog. A terrific account of the practicalities of installing the domestic battery, how it functions and the finances behind it. لقراءة كل التفاصيل….
Late last year, Elon Musk shocked everyone by announcing a new version of Tesla’s less-than-a-year-old Powerwall home battery system, with double the capacity for the same dough.
The other players in this industry need to have been gnashing their teeth, but bravely soldiered on with the expectation that “it’ll take them forever to deliver”.
Not so – my Powerwall2 was installed yesterday, one of the first in new South Wales, Australia – read on for the blow-by-blow and decide if you also want to be complimentary from power blackouts and 3-figure power bills.
What is a Powerwall Anyway?
If you don’t yet know what a Powerwall2 is, read this section – if you do, skip to the next heading.
Simply put, it’s a slim, no-maintenance, weatherproof and near-silent rechargeable Lithium battery system with the front profile of a bar-fridge, located near your power board, paired with a Gateway box that manages power flows from and to your home and the battery system.
Inside it, there’s heaps of cylindrical battery cells, set up into packs, which will also be used to power the upcoming model 3 electric car.
They are made in Tesla’s Nevada Gigafactory, and packaged inside a shiny white-painted steel enclosure, along with a charger, inverter, and water-cooling system.
The system has an installed cost of just over $10,700 in Sydney [Ed: currently £5,900 + installation in the UK] and you can get one with around a 2 month lead time today.
It’s created to save the output of your solar power system during the day, so when the sun sets (when your solar generation falls away), it will power your entire house until it’s nearly discharged. And, if there’s a power blackout, the PW2 switches to powering your house from the battery instantly, so you still have power for your entire home until power gets restored, or the battery runs down.
It’s capable of supplying 13 kWhr, or so, of stored energy when fully charged, which for a lot of homes will carry them through the night, and as a result saving you the cost of the power you would otherwise have to buy. The power level it can manage is 5kW Steady, 7kW Peak, enough to run a lot of kitchen appliances, a split-system airconditioner, or even charge a short-range electric automobile (such as a Mitsubishi Outlander PHEV, which only draws 2KW to charge, taking 5 hours).
For me, with 4.8KW of paid-off solar on my roof, a rough calculation says the PW2 could pay for itself in 6 to 9 years, and it’s called for for 10. If you don’t have solar power, it’s not for you, but given prices for power are only going to rise, you must consider getting solar cells anyway, if you own your home and have roofing space available. I’ll go through the financial aspects in detail towards the end.
The install Process
I reserved a Powerwall2 by means of Tesla’s site in October last year – it’s a quick and painless process, pricing is entirely available online, it’s transparent and up front, so you have no need to chase around for quotes.
This is a significant advantage Tesla has, as there’s a lot more than a few cowboys in this industry in Australia. Tesla’s checkout took a $500 deposit by credit scores card at buy time, they followed up with several phone calls over the intervening months, a contractor (Downer EDI) did a site check out a few weeks before install, and then Tesla requested payment by bank transfer for the balance of the $10k this week.
7.00am: two tradie vans arrived immediately as promised, from a local solar outfit called Flash point Solar in Punchbowl. another person from Downer also arrived to supervise. As it turns out, this was the first install for all of them.
The gear came in two large cardboard boxes – the Gateway, and the Powerwall2 itself. The PW2 weighs over 125kg (290 pounds says the sticker, but another one next to it says 67Kg, so clearly the whole “metric system adoption” in the us still has some bugs in it), with the result that a trolley is needed to shift it around. It is just large enough to fit through a conventional door.
8.00: Hardest part so far is figuring out where the wall studs are for the mounting bracket. My house has plastic cladding, so they can’t easily find the studs. .
The PW2 is expected to rest on the ground on feet, and the bracket is indicated to stop it from tipping over.
8.30: looks like they are working it out as they go – 5 people here now – 3 from Downer, of which 2 were here just to learn, and they said they had done some training with a prototype.
9.00: Mounted, and then had to remove it.

They ended up putting a bigتم حجزه هنا في نطاق “الآلاف”. تراكم الأجهزة هو شهرين إذا كنت تشتري الآن. لا يمكن لكل فريق من المثبتات القيام بتثبيتات 1-2 فقط يوميًا ، وأعتقد.
إلى حد ما ، الموزع الذي تربطك بالسلاسل للتحكم في متى سيتم التثبيت ، نظرًا للسياسات المختلفة وعمليات الموافقة على المعدات التي يتمتع بها ، والتي تتجاوز سيطرة Tesla ، لذلك تعطي Tesla الأولوية للتركيبات على العملاء الذين تم ربطهم بالموزعين الذين اجعل الموافقات جاهزة الآن.
كالعادة ، فإن Elon يتجه إلى أصابع قدمي في هذه الصناعة ، من خلال جعلنا من الممكن بالنسبة لنا أن يقللوا من اعتمادنا على احتكارات الطاقة – سوف يفعلون بطبيعة الحال كل ما في وسعهم للحد من امتصاص تخزين البطارية السكنية.
AC VS DC: في حين تحدثت Tesla في البداية عن كل من Powerwalls المشحونة DC و AC ، فقد استقروا فقط على القيام بمشاهدة ACD-يقول تيم إن هذا يزيل أي مشكلات قد تتطور من قدرات DC المختلفة للكثير من الطاقة الشمسية المختلفة تستخدم المصفوفات في جميع أنحاء العالم ، مع الأخذ في الاعتبار أن مخرجات التيار المتردد من العاكس الشمسي الحالي تقليدي إلى حد ما بالمقارنة. نعم ، هناك بعض الخسائر في تحويل طاقة التيار المتردد إلى العاصمة في البطارية ، والعودة مرة أخرى ، لكنها تشير إلى وقت أقصر للتسويق ، وإصدار شهادة مبسطة ، وتحكم أفضل في عملية الشحن ، وانخفاض الأسعار بسبب تحجيم نوع واحد فقط ، و لا يوجد أي شرط لمثبتات PW2 أن يضطروا إلى التغلب على إعادة توصيل إعدادات الكابلات الشمسية الحالية.
التكليف: يعتمد تمكينه في يوم التثبيت على لوائح موزع الطاقة الخاصة بالعميل. يوجد مفتاح على البطارية ، وآخر داخل البوابة لتجاوز النظام.
أنا مع Endeavor NSW ، يسعدني أن يوقعوا شرارة على ذلك ، في حين أن بعض الموزعين الآخرين يصرون على المفتشين المعتمدين من L2 ، ومثل ذلك. على ما يبدو ، فإن Endeavor على ما يرام مع ما يصل إلى 10 كيلو وات من الطاقة الشمسية على منزل أحادي الطور.
الأحمال الزائدة: سألت ما الذي سيحدث إذا تجاوز السحب الحالي للمنزل إخراج الطاقة في PW2 – قال تيم إن جهد الإخراج سيبدأ في الانخفاض ، ثم تعيد ضبط الوحدة ، لإلقاء الأحمال وإعطائك فرصة لإيقاف أي شيء يرسم الكثير – سيكون هذا هو نفس السيناريو كما هو الحال عندما برزت قاطع الدائرة الأسبوع الماضي ، حيث كان هناك سخان شحن للسيارات+غسالة صحون+ميكروويف+كل شيء عليه في نفس الوقت ، وذهب الحمل إلى 8 كيلو وات.
الصوتيات: إنه يجعل “علامة” باهتة في بعض الأحيان ، وصوت ذي النغمة المنخفضة عند تشغيل المروحة. سوف تسمع هذه فقط إذا كنت تجلس مثاليًا بجوارها. تهب المروحة الهواء من الزاوية العلوية اليمنى ، مقابل المبرد. إنه أكثر هدوءًا من العاكس الشمسي ، والذي يصدر دائمًا ضجيجًا محددًا.
السرقة: أشار بعض الناس إلى القلق بشأن تعرض الوحدة التي تعرضت للضرب ، مع الأخذ في الاعتبار أنها ليست وراء باب مغلق. ليس لدي أي طريقة لوضعها خلفها في منزلي (بدون مرآب) ، ولكن بالنظر إلى أنه يزن 130 كيلوجرام ، لن يكون المشابك العشوائية قوية بما يكفي لرفعه ، وسيحتاجون إلى حافلة على السحب إلى yank قبالة الجدار ، بسبب مقطع Fiddly.
بالنظر إلى سياسة Tesla التي لا تنعش ، أفكر في الغالبية العظمى من الناس هنا لن يكون لديهم أي فكرة عما يفعله هذا الصندوق الأبيض الغامض على الحائط ، أو ما يستحقه. ولدي نظام سلامة النسخ الاحتياطي فقط في حالة …
تطبيق الهاتف Tesla
يمكنك تنزيل تطبيق Android أو iPhone المجاني من Tesla لإدارة Tesla Automobiles و PowerWalls. لم يكن لدى تطبيق Tesla أي أجهزة مسجلة في اليوم التالي للتثبيت ، وقال تيم ، في ذلك الوقت ، أن شخصًا ما في Tesla USA سيحتاج إلى وضع مربع. لقد طاردت جهة اتصال Tesla Email التي أجريتها لعملية الدفع ، واتصل مرة أخرى بعد ساعة ليقول إنه تم ذلك (في صباح يوم السبت أيضًا).
في الأساس ، يتيح لك معرفة ما إذا كان كل شيء على ما يرام مع النظام ، من خلال مراقبة حالة تدفقات الطاقة وحالة شحن البطارية. طيه بعض لقطات الشاشة:
هذه هي الصفحة الرئيسية التي تحصل عليها بعد تسجيل الدخول. يستغرق الأمر حوالي 5 ثوانٍ لجلب الحالة الحالية عند فتح التطبيق ، وتعطي نظرة سريعة لمعرفة ما تفعله البطارية ومدى امتلاءها. في هذه اللقطة ، يتم تفريغني تقريبًا ، وتم استخدام القليل جدًا من الطاقة من الطاقة الشمسية
