Tesla plans to sell a residential-scale storage battery called the Powerwall and a commercial-scale battery called the Powerpack. Here's what they entail.
• Powerwall: Homeowners can pay $3,000 for a 7 kilowatt-hour battery or $3,500 for a 10 kilowatt-hour battery, plus installation. Deliveries begin late this summer.
• Powerpack: Tesla will bundle larger batteries into installations of between 500 kilowatt-hours and more than 10 megawatt-hours. The cost: $250 per kilowatt-hour.
