Panasonic has introduced two new EverVolt solar module families and an updated EverVolt home battery energy storage system. Olympic gold medalist and Panasonic brand ambassador Michael Phelps was on hand to promote the new product.

The next generation EVERVOLT® home battery system integrates a hybrid inverter, lithium-ion battery and the new EVERVOLT® SmartBox, an all-in-one home energy management device, in a compact design that can be installed indoors or outdoors, on floors or walls. A single SmartBox can stack up to four batteries, providing up to 30kW of power and 72kWh of available energy to meet even the most demanding demands.

5. Fluence

Fluence Energy, Inc. (FLNC)
Established Time2018
Headquarters locationArlington, VA, USA

Backed by AES, which has ten years of experience in the energy storage industry, and Siemens, a global electrical giant that has worked for decades in the international market, Fluence not only received a large amount of capital investment at the beginning of its establishment in 2018, but also brought together the energy storage teams, technologies, customers and huge global channels accumulated by the two giants for many years.

Thanks to the parent company’s global business deployment, Fluence, which was born with a golden spoon, rose rapidly and gained a foothold in the United States, expanding its influence to the world. 

By 2019, Fluence has deployed energy storage projects to 17 countries, involving the deployment and winning of more than 760MW of energy storage projects. By 2023, Fluence’s customer experience covers more than 225 projects in 47 regions with more than 7GWh of completed projects.

Taking a close look at the rise of Fluence, although the origin of a rich family makes it to a certain extent, “on the scale of short and long” energy storage industry to occupy an inherent advantage, but it is the United States earlier mature energy storage business model and fully competitive industry soil, it really gave birth to Fluence in the context of the rapid development of the global storage market rapid expansion.

6. ESS

ESS, Inc.
Established Time2011
Headquarters locationWilsonville, OR, US

ESS Inc. is a fast-growing, venture-backed clean energy technology startup based near Portland, Oregon, whose corporate team has decades of experience in distributed generation and long-term energy storage technologies.

ESS manufactures low-cost, long-duration iron flow batteries for commercial and utility-scale energy storage applications. Its energy storage body uses iron, salt and water as electrolytes, providing an environmentally safe, long-life energy storage solution for the world’s renewable energy infrastructure.

ESS iron flow batteries are safe and non-toxic, and the battery system is essentially recyclable at the end of its service life.

In Tesla’s business segment, the energy storage business growth rate is far ahead. The increase in Tesla’s 2022 energy production and storage revenue is mainly due to the increase in the installed capacity of Megapack and Powerwall, and the increase in the selling price of Megapack.

10. Sonnen

Sonnen Group
Established Time2010
Headquarters locationBavaria, Germany

Sonnen, Europe’s largest producer of energy storage batteries, was founded in 2010 to manufacture lithium-ion batteries for storing wind and solar energy. 

In 2016, less than six years after its establishment, Sonnen has developed into the largest producer of energy storage batteries in Germany and even Europe, becoming a unicorn enterprise of the energy Internet.

In the same year, Sonnen beat Tesla’s Powerwall home energy storage product with a slight sales advantage to become the world’s largest seller of home battery products. It has thus become Tesla’s biggest competitor in the field of home batteries.

Entering 2023, the German household light storage market continues to accelerate its expansion, and the demand for household photovoltaic energy storage systems has risen sharply. This has allowed Sonnen, based in Bavaria, Germany, to expand its capacity and now produce about 120,000 household optical storage systems per year. The German Solar Association reports that about 214,000 new battery storage systems were installed in Germany last year.

According to more detailed data from RWTH Aachen University, more than 110,000 new household photovoltaic energy storage systems were added in Germany in the first quarter of 2023 alone. Industry experts predict that Sonnen, as the leader in household optical storage systems in Europe, will have more than 1 million installed systems.

Sonnen connects its home photovoltaic energy storage systems to virtual power plants, allowing them to provide power frequency services in the power balance market, among other things, and help battery systems achieve grid stability – which is still largely dependent on conventional power plants or large storage facilities.
