SolarEdge DC Optimized Inverters and Telsea

SolarEdge will be supplying an inverter system that will enable photovoltaic (PV) and grid integration with Tesla’s recently announced Powerwall home battery – a storage pack capable of supplying electricity for homes when the sun goes down. Combining their technologies, the partners said they are building upon SolarEdge’s DC-optimized inverter solution and Tesla’s automotive-grade energy-storage technology to provide a more economical solution for residential solar generation.

“Tesla’s collaboration with SolarEdge unites leading organizations in two rapidly growing industries, solar energy and energy storage, to bring homeowners a more cost-effective and integrated energy generation, storage and consumption solution,” Tesla CTO J.B. Straubel said. “SolarEdge’s commitment to improving the value of PV systems through product innovation, combined with more than 1.3 gigawatts of successful deployments, makes it an ideal partner for Tesla to develop and introduce this new energy-storage solution to the PV market.”

Tesla, which has dazzled the electric-car market with its fastcharge car batteries, announced its new wall-mounted rechargeable battery last week.

The Powerwall will be available in a 7-kilowatt-hours daily cycle version for everyday use and for backup in the event of a power failure or disaster. This inverter system is priced at $3,500.

The battery is designed to collect solar energy accumulated daytime hours and use it to power the home in the evening and morning, when electricity usage is highest but sunlight is lacking.

“We have this handy fusion reactor in the sky called the sun. You don’t have to do anything – it just works. It shows up everyday and produces ridiculous amounts of power,” Tesla CEO Elon Musk said at last week’s launch event for Powerwall, which was fully powered by solar-charged batteries.

The batteries could potentially provide a sort of “smart grid” solution without actually needing a smart grid, according to Tesla. Although they are marketed as a solution for storing solar power, the batteries can also store electricity from the grid during less-expensive offpeak hours and then supply it to the home during the expensive peak hours when there is highest demand.
