Tesla Lines Up Home Battery Customers With Sunrun

Sunrun, a privately held rooftop solar systems provider, agreed to add Tesla Motors Inc TSLA's recently announced Powerwall Home Battery to its line of storage offerings.

San Francisco-based Sunrun counts more than 50,000 residential customers and has raised $155 million in venture capital from Accel Partners, Sequoia Capital, Foundation Capital, and Madrone Capital Partners.

SolarCity Corp SCTY said separately Friday said it will offer Tesla's Powerwall batteries to its residential customers, and will also use Tesla batteries in its DemandLogic energy storage system.

Both Tesla and SolarCity are headed by Elon Musk.

SolarCity's customers include "tens of thousands of homeowners," as well as government and corporate clients.

Tesla traded Friday at $224.67, down 0.6 percent; SolarCity changed hands recently at $61.59 up 2.57 percent.
