SolarEdge CSS-OD Commercial Battery Cabinet — Intelligent Storage at Scale
The SolarEdge CSS-OD is a factory-assembled, outdoor-ready energy storage system designed for commercial and industrial applications. Delivering 102.4kWh of total capacity and paired with a 50kW inverter, it’s the ideal choice for C&I sites seeking to cut peak demand charges, increase self-consumption, and boost energy resilience.
Why Choose the SolarEdge CSS-OD?
- Factory-built integration: Pre-wired and tested for faster installs, with indoor or outdoor placement.
- Intelligent site control: Managed via SolarEdge ONE for C&I platform to optimize battery use in real-time.
- Flexible scalability: Connect up to 2 cabinets per inverter and expand sites to 1MWh+.
- Peak performance: Up to 97.5% inverter efficiency and 0.5C charge/discharge rate for fast cycling.
Enterprise-Grade Safety and Monitoring
The CSS-OD includes comprehensive safety layers:
- Dual fire suppression (active and passive)
- Ground, leakage, and reverse polarity protection
- AC/DC surge protection built in
- Flood, temperature, and door sensors
- Cyber-secure communication via a single trusted gateway
Designed to meet global safety standards including IEC 62619 and UN38.3 for transportation.
Smart Storage for Smarter Business
Through the SolarEdge ONE platform and the dedicated controller, the system adapts in real time to site needs — prioritising solar self-consumption, peak shaving, or dynamic tariff shifting. Microgrid-ready with optional Backup Interface (in select regions), it offers total energy independence for mission-critical loads.
Who is it for?
This system is ideal for:
- Commercial and industrial businesses looking to reduce grid dependency and energy costs
- Facilities with peak demand spikes seeking load smoothing and backup
- EPCs and integrators building smart, scalable solar + storage solutions
