sonnenCommunity: ‘A utility without power plants’ The big attraction with sonnenBatterie is that you can buy the full package – solar panels, inverters, control technology and of course the lithium-ion battery pack – for little more than 10,000 euros. (This is better than buying it all separately, although the battery isn’t the biggest out there.)

European energy storage manufacturer sonnen announced it is accelerating its presence in the US market by partnering with SolarWorld, PetersenDean, and Spruce. On Friday, the company also officially opened a new office in Los Angeles.
