Thinking back to the initial announcement of Tesla Energy, it feels like a lifetime ago. The launch was expected with the word already out on the street that Tesla was going to build a battery for home storage, but unexpected at the same time because no details were known.
At the news conference, Tesla blew everyone away with the announcement of a new entity, Tesla Energy, with two upcoming products — Powerwall and Powerpack. With this new launch, Tesla boldly proclaimed that:
“Tesla is not just an automotive company, it’s an energy innovation company. Tesla Energy is a critical step in this mission to enable zero emission power generation.”
Tesla shared that Powerwall is the residential product, with two pack sizes: a 7kWh pack intended for daily cycling and a 10kWh offering for weekly cycling. At its core, Powerwall is designed to “store energy at a residential level for load shifting, backup power, and self-consumption of solar power generation.” Powerpack, on the other hand, was said to be the utility-scale or business-scale product, with a larger physical footprint and a correspondingly larger storage capacity.
Fast forward to today and both products are running strong with Powerpacks being installed at large businesses across the globe, such as Target and Amazon Web Services. Forward-thinking utilities like Southern California Edison and Advanced Microgrid Solutions are also testing the waters with some larger installations.
Powerpacks are already being installed in Australia and in the UK, with other regions coming online over the next few weeks.
Supporting the early installations, Tesla Energy posted the Installation and User’s Manual for Powerwall, which, in addition to the more mundane bits about the physical installation, includes technical specifications and a few interesting insights into how it operates.
To secure the full 10-year product warranty, the Powerwall must be registered. This is a common requirement but is extra critical given that it’s a brand new product with what should be a long life ahead.
Immediately after the lengthy safety section, the manual busts out with a pretty sweet description of what Powerwall is. It starts out by boldly stating that it is “THE FUTURE OF SUSTAINABLE ENERGY” — just the type of bold leadership these new solutions need to succeed — then goes on to describe the purpose of Powerwall:
“Powerwall is a lithium-ion battery system that turns solar panels into an all-day resource while offering backup power in the event of a grid outage. Powerwall enables storage of renewable energy, allowing optimized home energy control and an increasing amount of total electricity production to come from renewable sources. Reliable renewable energy improves the resiliency of the grid, reduces energy costs, and increases the impact of electric vehicle ownership.”
