Tesla started testing the Powewall, its home battery system, with “pilot customers” last summer. At the time, a Tesla spokesperson told Electrek that the 7 kWh version of the battery pack was in production and that over the next few weeks they would “continue to ramp up to volume production”, but a few weeks later, the company moved the production line of its Tesla Energy products to the Gigafactory in Nevada, which delayed the ramp up of production.
The 10 kWh version of the Powerwall was supposed to follow a few months later.
The 7 kWh Powerwall cost $3,000 and is designed for daily cycling, while the 10 kWh version, which costs $3,500, has a different battery chemistry optimized for weekly cycling, making it more appropriate for backup power.
When Tesla announced the premature move of production to the Gigafactory, the company also said that it would accelerate the ramp up during the first quarter of 2016 and apparently, Tesla already started shipping the home battery as evidenced by sightings of custom crates made for the Powerwall:
Tesla will focus the first deliveries in markets where electricity rates are high. Germany, Australia and South Africa have been mentioned has potential early markets for the company’s energy division to focus on .
Some US markets will also have early access to the Powerwall. Green Mountain Power (GMP), an electric utility servicing 265,000 residential and business customers in Vermont, announced that it will receive 500 units over the first few months of 2016.
The company also sells Powerpacks; scalable 100 kWh battery packs for commercial and utility-scale projects. Tesla already inked a few Powerpack deals including a project with 3 high schools in San Diego and a 500 MWh supply agreement with Advanced Microgrid Solutions.
