The Tesla Powerwall 2 – second-generation battery announced

Announced at Universal Studios in Los Angeles on Friday, Tesla and Elon Musk revealed two of their latest inventions – Solar Tiles and the Powerwall 2.

Compact and stackable, the Powewall 2 can power a two-bedroom home for a full day and provides a simple installation for both domestic homes and small businesses. Combined with a solar array, the Powerwall 2 can power a four-bedroom home indefinitely.

What’s different about the Powerwall 2?

The Powerwall 2 offers several distinct differences and advantages over its predecessor.

Capacity

The Powerwall 2 offers 13.5kWh usable capacity at 100% depth of discharge. This is more than double the 6.4kWh offered by Tesla’s first generation battery.

The extra capacity provided by the new model means that a Tesla battery combined with a solar PV array can provide full power for a four-bedroom home.

Built-in Inverter

Previously, the Powerwall required installation of an additional inverter.

However, with this technology now built into the Powerwall 2, installation of the battery solution is now easier than ever. In addition, spaced consumed by an installation is reduced and systems are tidier.

Stacking

The Powerwall 2 offers complete stacking possibilities.

This means the Powerwall can now provide electricity to homes with larger electricity demand and, even, small businesses. Customers can stack up to nine batteries together.

Size

The Tesla Powerwall 2 is smaller than the original unit.

Shorter, thinner and narrower than the original Powerwall, Tesla’s second-generation battery provides a more space-conscious installation. Furthermore, removing the need for an external inverter minimises space consumption.

Solar Tiles

Also introduced by Elon Musk at the recent reveal were Tesla’s Solar Tiles.

Expected for installations in 2017, Solar Tiles look to provide a cost-effective, energy-friendly, visually-appealing alternative to traditional roof tiles. Tesla’s long-term aim is for all new homes to be built using Solar Tiles to help combat the rising impact of global warming.

More information on Solar Tiles to follow shortly.
