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
- Rated up to 24A for output current
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: S1400 Power Optimisers are rated up to 24A for output current. Therefore, they are NOT suitable to be used with SolarEdge Inverter models that have integrated 25A or 30A DC-fuses. To replace these fuses you will require the part SE-FLD-3PH-NEUTRAL-LINK to replace these fuses to allow the S1400 to be compatible with the Manager inverters
- If paired with any of the fused commercial inverters, the customer is required to replace the fuses inside with SE-FLD-3PH-NEUTRAL-LINK. 1 for each fuse. 4x SE-FLD-3PH-NEUTRAL-LINK per Manager unit
