SolarEdge Technologies announced the launch of its CSS‑OD 197 kWh commercial storage system, a higher‑capacity solution designed for indoor and outdoor commercial and industrial (C&I) solar installations across Europe and Asia. The announcement was made on April 21 2026 and expands the company’s existing C&I storage suite, which previously included the CSS‑OD 102.4 kWh model introduced in late 2024.
The new CSS‑OD 197 kWh platform is scalable up to 1 MW and 4 MWh per site and can operate as a standalone battery or be AC‑coupled to a photovoltaic system. It supports a range of applications—including self‑consumption, peak shaving, and tariff optimization—making it suitable for a variety of commercial customers that require larger storage footprints.
Demand for higher‑capacity storage is accelerating in Europe and Asia, driven by regulatory incentives that favor self‑consumption, rising electricity prices, and the need for grid flexibility. SolarEdge’s integrated solar‑storage architecture delivers higher efficiency and simplified installation, positioning the company to capture a larger share of these markets where customers are seeking more robust, turnkey solutions.
SolarEdge’s main competitors in the commercial storage space include Huawei, Sungrow, and Enphase, while its broader inverter and storage portfolio competes with Tesla, BYD, and other global players. The CSS‑OD 197 kWh differentiates itself through its tight integration with SolarEdge’s high‑efficiency inverters, proven track record from the 102.4 kWh launch, and the ability to scale quickly to meet the growing demand for larger capacity systems.
Naama Ohana, Chief Commercial & Industrial Division at SolarEdge, said the market response to the first CSS‑OD was “extremely encouraging,” creating a strong new revenue stream from new sites and the company’s large C&I solar install base. She added that the higher‑capacity battery will unlock additional opportunities for partners, especially for sites that need more storage as self‑consumption in the C&I sector continues to accelerate. The launch builds on the strong adoption of the earlier model and signals SolarEdge’s commitment to expanding its commercial storage footprint in high‑growth regions.
