Tesla Powerwall 2 – arguably the most anticipated energy product ever released. It is an energy revolution.

The Powerwall allows you to store and use any energy that your solar PV system generates during the day.

But it does so much more. The Powerwall offers in depth monitoring has an upgrade feature which allows it to automatically receive software upgrades from Tesla. It also higher than average cycle times compared to other battery systems and features a 10 year warranty.

Powerwall 2, has nearly double the storage capacity of the first generation and features a sophisticated monitoring and warranty technology.


Energy independence

Many people dream of turning their home into an energy island and disconnecting from infinitely rising costs of greedy power companies. But did you know that getting solar and battery storage an save you thousands of dollars off your power bill while giving you the reliability of the grid?

It’s also far more expensive (and less sustainable) than most people think to go off grid. Off-grid packages for homes start at $28,000 and require diesel generator backups to provide during long periods of low sun. They also require their own, well ventilated space.

Reducing power bills

Historically, power bills have ever only gone in one direction – Up. Even gas, which traditionally has been cheaper than electricity has risen by significant amounts and is starting to close the gap.

A solar PV system on its own can generate enough energy for all your daytime energy needs, but with a battery system like Tesla Powerwall 2, any extra energy generated by your solar PV system can be stored to be used at night. By using all of the energy generated by your solar PV system you will need less power from the grid, lowering your energy bill.

How the Tesla Powerwall works

Battery technology is as simple as it is impressive. Normally, any excess energy that is created by your solar panels is sent to the energy grid. A home battery system like Tesla Powerwall 2 will capture this energy and make it available for use at night. If you generate enough of your own electricity, it will charge itself completely from solar.

Then, depending on your energy habits, Powerwall 2 can power your home for an entire evening from power you generated during the day.

It’s better than being off-grid.

Powerwall 2

Powerwall 2 is more than a simple upgrade, it is a complete redesign of the battery storage system.

Key features of Powerwall 2 are:

  1. 13.5 kWh of battery storage – nearly double of the first generation
  2. Built in battery inverter – the first generation Powerwall required a separate battery inverter to be installed. The new Tesla Powerwall will have this built in.
  3. 10 year warranty.

This US based presentation is a great explanation of the whole Tesla ecosystem. Lots of focus on the Solar tiles but worth watching just to understand how it all fits together.

The world is transitioning to sustainable energy. Powerwall 2 is a battery for homes and small businesses that stores the sun’s energy and delivers clean, reliable electricity when the sun isn’t shining. Combine Powerwall, solar and an electric vehicle to create a zero emission lifestyle. The sun provides more than enough energy in just one hour to supply our planet’s energy needs for an entire year. Your home can capture this free, abundant energy source through rooftop solar turning sunlight into electricity for immediate use or storage in a Powerwall battery.
