Sonnen, which has launched the SonnenCommunity energy trading platform in its homeland in addition to selling over 10,000 residential units, is also active in the US, having initially targeted the commercial peak shaving market there before adding residential offerings earlier this year. The company is also expanding into other territories including the recent hire of a small team in the UK based at an innovation park in the west of England and the recruitment of distribution partners. In its recent Q1 results, Sonnen said it had sold 2,600 storage units in three months.
Other companies listed as part of GE Ventures’ energy portfolio on its website include SolarEdge, energy metering and analytics firm Tendril – in which SunPower is also an investor – and US residential solar leasing company Sungevity.
GE Ventures is also an investor in US commercial energy storage provider Stem, which has just closed a US$15 million Series-C funding round with capital from other major investors including European power utility RWE and Mithral Capital Management, another venture capital specialist.
Stem's marketing director Gabe Schwartz told Energy-Storage.News that the recent interest of majors such as RWE, Total, E.On and Engie in various energy storage companies was indicative of big players in the global energy market "seeing the energy storage space as somehow strategic to their larger business".
