Elon Musk announced Tesla’s home and business battery systems less than a week ago. With pricing starting at $3,000 (which doesn’t include installation), many questioned whether or not the platform would be a success. Based on Musk’s comments during the company’s recent earnings call, it’s probably fair to say that Tesla is certainly on to something.

Musk said that since its announcement, more than 38,000 customers have reserved a Powerwall system for their home. The company’s business solution, the Powerpack, has already seen 2,800 reservations.

As the CEO noted, the response has been overwhelming and there is no way they’ll be able to satisfy demand this year. In less than a week, the company sold out through the middle of next year.

With that kind of demand, one has to wonder if it’d be in Tesla’s best interest to shift its attention away from automobiles and towards stationary power. When asked this question, Musk said it just might and they’d have a better idea on the subject in a year.

Looking ahead, Musk said his company ultimately expects most of their stationary storage sales will be at the utility or industrial scale. As for its automotive business, the entrepreneur said Tesla plans to launch its Model X SUV late in the third quarter. The company’s mainstream vehicle, the Model 3, will be shown in March 2016 with production starting in late 2017.
