EmPower Solar of Island Park is working with Tesla, the electric-car maker that owns national solar installer and panel maker SolarCity, to offer that company’s Powerwall storage system, which provides up to 30 hours of off-grid energy, said David Schieren, EmPower’s chief executive. The company has 20 systems on order, he said. Like SunRun’s BrightBox, the unit automatically turns on if the grid goes down, keeping homes powered “without interruption,” Schieren said.
