SolarEdge CSS-OD 197: New C&I Battery Scales to 1 MW / 4 MWh
SolarEdge has unveiled the CSS-OD 197, a 197 kWh commercial and industrial battery cabinet based on LFP chemistry that can scale up to 1 MW / 4 MWh. The system is already being deployed across key European markets including Germany, Austria, Switzerland, the Netherlands, Poland, and France.
SolarEdge is expanding its commercial and industrial (C&I) energy storage portfolio with the launch of the CSS-OD 197 — a pre-assembled battery cabinet delivering 197.12 kWh gross capacity and 187.15 kWh usable, built on lithium iron phosphate (LFP) chemistry. LFP cells are favored in large-scale applications for their thermal stability, long cycle life, and enhanced safety profile.
The system is designed for modularity and scalability. Each cabinet houses 11 battery modules and supports a maximum charge/discharge rate of 0.5C. Paired with a 50 kW or 100 kW battery inverter, multiple units can be combined to reach either 1 MW / 2 MWh or 1 MW / 4 MWh — the latter requiring up to 20 inverters. Jacques van der Bijl, SolarEdge's Director of C&I Products for Europe, confirmed the company has already received customer inquiries at the full 1 MW / 4 MWh scale.
SolarEdge initially entered this product category in 2024 with the smaller CSS-OD 102 (102 kWh), targeting Italy's subsidy-driven market. The new CSS-OD 197 signals a broader European push, with active installations already underway in Germany, Austria, Switzerland, the Netherlands, Poland, and France — markets where C&I solar-plus-storage demand is growing rapidly amid high electricity prices and tightening grid regulations.
For businesses operating large rooftop solar arrays or ground-mounted PV installations, behind-the-meter storage solutions like the CSS-OD 197 offer a compelling way to maximize self-consumption, reduce peak demand charges, and build resilience against grid disruptions — all increasingly important considerations across the EU energy landscape in 2026.
