　　Solarwatt flexes muscles in home energy storage fight with Shell, Tesla

　　Germany's Solarwatt, backed by BMW's billionaire shareholder Stefan Quandt, plans to launch a small module that lets homeowners link rooftop solar panels to power storage batteries and electric vehicles to cut costs.

　　The wall box allows homeowners to control when and how much home-produced photovoltaics (PV) power they store, use to charge their electric vehicles (EVs) or sell to the grid.

　　The move takes aim at Shell-owned Sonnen, Germany's E3/DC, EnBW's Senec, LG Chem, Varta and Tesla, which EuPD Research says dominate the home storage market.

　　"The energy manager is the brain of the home," Peter Bachmann, Solarwatt's Vice President Customer Solutions, told Reuters ahead of a launch planned for Wednesday.

　　"It distributes the power from the roof intelligently."

　　The Manager Flex device, which looks like a wifi router and will go on sale at around 500 euros ($594), allows the integration of energy flows and gadgets at home, such as rooftop panels, batteries, electric heat pumps and EV-charging boxes.

　　"We are showing that we have a holistic way of thinking in our DNA," Quandt, who owns a majority of Solarwatt, said last month.

　　Germany is an obvious starting point. With 300,000 stationary batteries, it is the world's top home storage market, ahead of the United States, Japan and Australia.

　　Germany's battery market has grown tenfold since 2015 and is set for 60% growth this year, fuelled by its 16 million house owners, of which two million operate solar panels.

　　Currently, it costs 7 euro cents to produce a kilowatt-hour (kWh) of solar power in Germany, a fifth of grid power.

　　A household installing panels for generation, an electric heat pump to replace oil or gas boilers, and buying an EV instead of a petrol-based car can cut its CO2 emissions by 89%, it said.
