How To Survive A Blackout With Tesla Powerwall

Solar battery storage blackout protection


Protect Your Households From Blackouts With Solar Power & Battery Storage

Sydney suffered through 4 major storms last summer, with the latest storm creating a serious wave of damage that left some of the 110,000+ homes without power for many days.

Ausgrid said over eighty thousand homes were without power as wind gusts and severe rain swept across Sydney, Newcastle and the Central Coast bringing down trees and causing serious damage to property. Large storms and heatwaves are increasing in frequency across NSW, placing an increased strain on the power grid.

The most recent storms had 80,000 homes in blackout.

Protect Your Home During A Blackout

Due to the uncertainty, many households are now turning to battery storage solutions to ensure their power supply is uninterrupted if the grid goes down.

While storms were raging, Mark, a long time Powerwall customer, was relaxing over a hot meal and watching TV before bed. Mark’s neighbours, on the other hand, were all without power. So was his entire suburb.

Mark was one of the lucky few people who used Tesla Powerwall to power his home with stored solar energy throughout the blackout. Battery storage has completely revolutionised the way Australian households use, store and manage their power, now making it possible to run your household on solar power 24 hours a day – even during a blackout.

The Tesla Powerwall enables solar households to further reduce their power bill and maximise self-consumption of solar power. In fact, with a capacity of 13.5 kWh a typical family home will be able to run all evening on stored solar power through to the following morning when the solar system turns back on again.

Powerwall comes with compatibility with any existing solar system plus it can provide backup power for when the grid goes down, a feature that is becoming more important in these uncertain times.

Power Outage Causes Chaos For 80,000 homes in Sydney

The recent storms in Sydney left a trail of destruction across much of Sydney with over 80,000 homes left without power.

In an extended blackout, not only can Tesla Powerwall keep the lights on, it can also help you:

  • Have a home-cooked meal while the storm is raging outside
  • Keep the fridge and freezer running
  • Charge your phone and keep the internet connected
  • Open the garage door – a very real-world problem!

Many suburbs across Sydney were recently without power and Ausgrid was unable to cope with the sheer amount of damage (previous storm on map below).

How To Survive A Blackout With Tesla Powerwall

Step 1 – Get Solaray To Install Your Powerwall, which charges itself from solar or the grid.

Step 2 – Set up Tesla Powerwall to your needs. 

Having Tesla Powerwall means that you’re not reliant on the grid anymore – blackouts won’t stop you now.

Compact, stackable and with a built-in inverter, Tesla Powerwall enables solar households to be free from grid disruptions and run all evening on stored solar power or low-cost off-peak grid energy. Designed for efficiency by Tesla, Powerwall is a premium choice for ensuring your home is running if anything disrupts grid energy.

It’s also first in its class for simplicity, design and energy efficiency. The cutting edge of energy generation technology with online monitoring and online firmware upgrades.

Use low-cost energy during the evening and morning when energy costs are at their highest, completely free from the grid. Combine your solar setup with Tesla Powerwall, which lets homeowners charge with self-generated solar energy during the daytime, or just charge during off-peak times for low-cost energy.

Tesla Powerwall gives you the freedom to choose low-cost grid energy or solar you’ve generated. Regardless of which way you charge it – blackouts won’t stop you now.

1. Generate Solar Power

Rooftop solar is now more affordable than ever, with a quality solar panel installation paying for itself within 3-5 years. This energy is then mostly exported to the grid, for which homeowners get paid. The goal of getting your solar panels is both in getting a good return on investment, but also having the panels not break in the first 10 years of use. Contact us directly before purchasing solar panels and we’ll be happy to guide you through the various steps to installing the right solar system for your home.

2. Store Energy At Home

A Tesla Powerwall solar battery lets you store energy you generate from solar during the day until the evening when you actually use that power.

It also lets you power your home entirely from the battery in the event of a blackout or power disruptions.

Tesla Powerwall is basically a giant rechargeable lithium-ion battery that’s mounted to the wall in your home. It can just be hooked up to the local power grid, or it can charge from your solar panels.

Everything needed to make the Powerwall a self-managed energy storage hub is already built-in, including automatic software updates from Tesla.

Most rooftop solar energy is generated during the daytime when people are at work or school, so you still end up paying for power usage from the grid at a much higher cost than you get paid to export.

With a built-in inverter, Tesla Powerwall enables solar households to run all evening on stored solar power.

Designed for efficiency and ease of use by Tesla, sleek and wall-mountable, Tesla Powerwall is a premium choice for energy storage.

3. Online Monitoringtesla-mobile-app-powerwall

Just in time for the release of Powerwall, Tesla Energy has also launched an updated version of the My Tesla web site & mobile app featuring solar system monitoring and Powerwall integration.

The app allows both homeowners and Solaray Energy to ensure the home’s energy management system performs at optimal levels, and anything that could go wrong is spotted and resolved in realtime, not months later when the energy bill comes in.

App users are able to monitor real-time data from solar power generation through a new Power Flow screen, which provides an overview of household energy storage and consumption by connected Tesla Energy products. Users can check the system’s status at any point from the app.
