Installations of solar system and solar energy storage systems for residential use in the U.S. are both growing. sonnen announced the launch of sonnenBattterie eco compact, a grid-tie solution that can optimize solar consumption, for the rapidly growing demand for storing solar energy.

sonnenBatterie eco compact is approximately 40% cheaper that sonnen’s other products. A fully-integrated 4kWh eco compact system retails for US$5,950 without installation for an inverter-included system. It is an all-in-one residential solar battery solution and represents the latest evolution of the company's smart energy management products. The sonnenBatterie eco compact is available for pre-order today and products will ship by the end of Q4 2016.

"We've seen increasing demand from our installation partners for a lower cost energy storage product that enables homeowners to use more of the power generated by rooftop solar systems," says Boris von Bormann, CEO of sonnen, Inc. "With the sonnenBatterie eco compact we are providing a simple, cost-effective version of our proven energy management technology that enables more solar-powered homeowners to supply up to 100% of their own power needs."

The smart energy device features self-learning software that offers multiple functions. It can increase household solar self-consumption, manage time-of-use and support grid services. These functions will increase the daily consumption of self-generated renewable energy as well as peak time-of-use at a lower cost so that residential customers will see a greater return on their solar investment.

The modular design allows sonnenBatterie eco compact to be scalable to 16kWh in a single compact unit. With enough storing capacity, homeowners can even reach 100% renewable for their daily power consumption.
