SolarEdge’s new CSS-OD 197 series ESS can be scaled up to 1 MW/4 MWh PV plus storage site
Its real-time operations are monitored and controlled by the SolarEdge ONE energy management system
This ESS is commercially available across Europe and Asia
SolarEdge Technologies, Inc., a global supplier of PV and DC optimized inverters, has launched a commercial and industrial (C&I) stationary energy storage system (ESS) in Europe and Asia. According to the company, the product is aimed at prosumers seeking solutions that support self-consumption, demand reduction, time-of-use electricity pricing, and grid flexibility amid declining net-metering incentives.
The new ESS, called CSS-OD 197, combines a 197 kWh battery cabinet with either one or two 50 kW inverters, providing output configurations of 50 kW or 100 kW. At the same time, this capacity can be expanded to 1 MW/4 MWh ESS site by connecting multiple units in parallel. It can operate as a standalone or AC-coupled storage system.
On the operation side, it coordinates PV yield, battery storage, and grid export in real time through its SolarEdge ONE energy management platform. This platform supports several C&I energy management applications, including self-consumption maximization, peak shaving, tariff optimization, and import/export limit management.
In terms of installation and commissioning (I&C), it has pre-assembled battery cabinets, which simplifies the I&C processes, either indoor or outdoor.
Naama Ohana, head of SolarEdge’s Commercial & Industrial Division, said demand for higher-capacity storage systems is growing as commercial customers seek greater energy independence and additional opportunities to optimize electricity costs.
This product is currently commercially available for European and Asian customers. SolarEdge added that this launch follows the earlier introduction of the CSS-OD 102.4 kWh storage system in late 2024.
