The company provides downstream solar-and-storage exposure, with performance affected by installation volumes, financing terms and customer economics.

SolarEdge Technologies supplies power optimizers, inverters, monitoring and energy-management products for solar installations. Its storage offering includes home batteries and equipment that coordinates solar generation, battery charging and electricity use.

The company serves residential and commercial markets through distributors and installers. It has wound down parts of its former battery-cell manufacturing operations while continuing to sell batteries and storage-related power electronics. Its business therefore combines solar and storage equipment rather than operating as a dedicated battery-cell manufacturer or a storage-asset owner.

Fluence Energy supplies utility-scale battery-storage systems, operational services and software for energy assets. Its equipment and controls integrate batteries with grid connections and operating software, while service contracts support systems after installation. The company originated from the storage activities of AES and Siemens and became publicly listed in 2021.
