Key Features
- Specifically designed to work with SolarEdge commercial inverters
- Dual-panel optimisation supports two high-output or bifacial PV modules, reducing system hardware requirements
- Mitigates all types of module mismatch loss, from manufacturing tolerance to partial shading
- Single-bolt mounting and simplified cable management for faster installations
- Detects abnormal PV connector behaviour, preventing potential safety issues
- Module-level voltage shutdown for installer and firefighter safety
- Compatible with bifacial PV modules
- Superior efficiency of 99.5%
- Flexible system design for maximum space utilisation
System Capabilities
- Allows connection of two high-powered or bifacial panels in series to one power optimiser
- Enables uneven string lengths, longer strings, and mix of panel types and orientations on same string
- Reduces impact of partial shading on array performance
- Compatible with wide range of commercial PV technologies
- Higher operating current capability for increased power handling
Installation Notes
- Designed for commercial PV installations
- Short input cable (0.1m) configuration
- Single-bolt assembly for simplified deployment
- Integrated DC switch: No
- DC fuses: Not included
- Important: The S1200 has a higher operating current. When pairing with an inverter that has built-in 25A fuses, you must replace the fuses with 30A fuses before commissioning. A fuse replacement kit is available (Part number FLD-DCD-SEL1-FUSE). Applicable inverter Part Numbers: SExxK-xxxxIxxCx, SExxK-xxxxIxxDx, SExxK-TWxxIxxLx, SExxK-xxxxIxxZx
