Blackouts can happen at any time, and unless you are protected with a Tesla Powerwall, you could be without power for hours, days or even up to a week.

Protect Your Home From Blackouts With Solar Battery Storage

Recently, a suburb in Western Sydney was without power because of a large storm. Imagine losing power right before Australia Day with guests about to show up at the door expecting a BBQ and cold drinks.

Tesla Powerwall 2 provides blackout protection so that you can avoid these awkward situations and keep your house powered no matter what Mother Nature throws at you.

Sydney has experienced several power outages, with the latest one affecting thousands of 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 property damage. Large storms, floods, and heat waves are increasing in frequency across NSW, placing an increased strain on the power grid.

Power Is Out to More Than 110, 000 Customers in Sydney

The previous wave of blackouts from storms.

80, 000 Customer Lost Power During the Night Due to Electrical Storm

The most recent storms had 80,000 homes in 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 reduce their power bill further 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 until the following morning when the solar system turns back on again.

The Powerwall is compatible with any existing solar system and can provide backup power 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, but 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 2

Step 1 – Get 1KOMMA5° To Install Your Powerwall, which charges itself from solar or the grid.

Step 2 – Set up the Tesla Powerwall 2 to your needs. 

Having a 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. It is at the cutting edge of energy generation technology with online monitoring and online firmware upgrades.

Self Generation Mission

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 off-peak times for low-cost energy.

Tesla Powerwall 2 gives you the freedom to choose low-cost grid energy or solar energy 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 mainly exported to the grid, for which homeowners get paid. The goal of getting your solar panels is to get a good return on investment and have the panels not break in the first ten years of use. Contact us directly before purchasing solar panels, and we’ll be happy to guide you through the various steps to install the right solar system for your home.

2. Store Energy At Home

A Tesla Powerwall 2 solar battery lets you store the 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 case of a blackout or a power disruption.

Tesla Powerwall 2 is a giant rechargeable lithium-ion battery mounted on the wall of your home. It can be connected to the local power grid or charged from your solar panels.

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

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

With a built-in inverter, Tesla Powerwall 2 enables solar households to run all evening on stored solar power.

Designed with Tesla's efficiency and ease of use, the Tesla Powerwall 2 is sleek and wall-mountable and a premium choice for energy storage.

3. Online Monitoring


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

The app allows both homeowners and 1KOMMA5° to ensure the home’s energy management system performs at optimal levels. Anything that could go wrong is spotted and resolved in real-time, not months later, when the energy bill comes in.

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