A $4 million (£2.6m) smart energy homes pilot project has been launched in California.
Around 50 householders will have solar, storage, controllable thermostats and smart inverters installed in their homes.
The project, which was awarded $2 million (£1.3m) by the California Energy Commission, is a partnership between SolarCity and SunSpec Alliance and Southern California Edison.
Tom Tansy, Chairman of the SunSpec Alliance said: “The combination of advanced inverters, solar PV and energy storage – bound together using open source standard communication protocols – will deliver an array of benefits to all Californians.
“This project is a wise investment that will decrease energy costs, improve grid infrastructure at lower cost and open up new opportunities across the energy industry.”
The technology will be tested and validated before it is deployed to the grid.
