Tesla's new home battery business attracts partners

SolarEdge headlines the list of solar companies collaborating with the company.

Electric car manufacturer Tesla announced last week it was introducing a suite of batteries for homes, businesses and utilities, and now solar energy companies around the world are flocking to partner up with the California-based company.

Inverter specialist Fronius and residential solar provider Sunrun, both based here in the U.S., announced collaborations with Tesla on Monday. On Tuesday, German energy and IT company LichtBlick, and Australia startup firm Reposit Power, which will sell the Powerwall home battery system in the wholesale electricity market, announced deals.

But perhaps the biggest partnership announced this week is with Israel's SolarEdge Technologies Inc., a company that produces PV inverters, power optimizers and module-level monitoring services. The company's optimized inverter system, a device which more efficiently converts energy captured through solar panels into usable energy, is thought to be among the best on the market.

Designed to manage both functions with just one optimized inverter, the Tesla and SolarEdge solution will include remote monitoring and troubleshooting to keep operations and maintenance costs low.

"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 JB Straubel said in a statement released by the company.

Tesla's suite of battery systems already includes among its customers Amazon and U.S. utility companies such as Texas's OnCor and South California Edison. The home battery system isn't expected on the market until later this summer.
