A year after Elon Musk unveiled the Powerwall at Tesla Motors Inc.’s design studio near Los Angeles, the first wave of residential installations has started in the U.S. The 6.4-kilowatt-hour unit stores electricity from home solar systems and provides backup in the case of a conventional outage.

Two months after Puerto Rico’s governor took to Twitter and challenged Tesla Inc. Chief Executive Officer Elon Musk to “ show the world the power and scalability ” of his batteries, the U.S. territory announced that six of the company’s energy storage systems have been installed on the islands of Vieques and Culebra.

The Powerwall units have been paired with solar to supply electricity to homes and businesses that were plunged into darkness after Hurricane Maria tore through the region almost three months ago, Puerto Rico Governor Ricardo Rossello said in an emailed statement Tuesday. Virtually the entire island lost service after the storm devastated its power grid. Tesla, which now has seven Powerwall systems in the territory, installed the latest packs as “a humanitarian effort,” the governor’s office said.
