Sonnen Launches Lower-Priced Battery for Home Backup and Grid Services. After years of selling more expensive home battery systems, sonnen launched a new product Thursday to compete on cost with other mainstream options in the U.S. residential energy storage market. The Germany-based company, acquired by oil major Shell in 2019, designed its sonnenCore system to deliver daily cycling for grid services as well as backup power. It comes with a capacity of 5 kilowatts/10 kilowatt-hours and a price point of $9,500. That puts it in competition with the similarly sized and priced LG Chem Resu and Enphase Encharge batteries; it’s slightly smaller than Tesla’s Powerwall, which holds 13.5 kWh.
