sonnen launched into the US market late last year to take advantage of fast-growing demand for behind-the-meter storage solutions, particularly in California.
Production and sales in the US are off to a “very successful start”, the company says, with the US now its second largest market after Europe.
During the first quarter, privately-owned sonnen sold 2,600 of its plug-and-play sonnenBatterie storage systems – double what it sold in the final quarter of 2015.
