sonnen reduces U.S. residential energy storage system cost by 40% with new sonnenBatterie eco compact

The sonnenBatterie eco compact is an all-in-one residential solar battery solution and represents the latest evolution of the company’s smart energy management products. Using sonnen’s proven selflearning software, the eco compact provides various grid-tied functions - increasing household solar self-consumption, managing time-of-use and supporting grid services, not including backup power.

July 7, 2016 (LOS ANGELES, CA) - The U.S. residential solar energy storage market is experiencing

unparalleled growth due to the increase in solar installations and the end of net-metering across
numerous states. In order to meet the rapidly growing demand for storing solar energy, sonnen
announces the launch of the sonnenBatterie eco compact. The streamlined eco compact is designed
to increase grid-tied solar consumption and is available at up to 40 percent the cost of sonnen's
other products.

The sonnenBatterie eco compact is an all-in-one residential solar battery solution and represents the
latest evolution of the company's smart energy management products. Using sonnen's proven selflearning software, the eco compact provides various grid-tied functions - increasing household solar
self-consumption, managing time-of-use and supporting grid services, not including backup power.
sonnen's fully-integrated 4kWh eco compact system retails for $5,950 without installation for a
fully integrated system including the inverter, the durable battery modules with a 10,000 cycle
lifetime, the smart energy manager and the measurement technology. The modular design allows
the product to be easily expanded in 4kWh increments up to 16 kilowatt hours in a single compact
unit.

"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. As a
result we expect to see a dramatic increase in the installation of storage across the country".
The grid-tied eco compact is key to enabling solar powered homes to store excess solar for use later
in the day - increasing the daily consumption of self-generated renewable energy at a much lower
cost. By adding a sonnenBatterie eco compact to new or existing photovoltaic systems, residential
customers are expected to see a greater return on their solar investment by expanding the use of
solar energy throughout the day, including peak time-of-use reduction. In several markets the eco
compact provides an economic benefit to the end of net-metering in states like Arizona and Nevada
and enables customers to comply with self-supply programs in states like Hawaii by generating and
storing up to 100% of their own power.

sonnen's existing products are currently installed in over 12,000 households globally and include the
currently available sonnenBatterie eco protect, a robust residential smart energy management
system that provides backup power, off-grid, solar self-consumption and time-of-use for smart
homes. The sonnenBatterie pro is sonnen's commercial and industrial product that provides peak
shaving and demand response capabilities and is available in Q4 2016.

The sonnenBatterie eco compact is available for pre-order today and products will ship by the end of
Q4 2016.
