SolarEdge S1400 Power Optimizer (Short Input 0.1m)
- S1400 Power Optimizer (Short Input 0.1m)
- Part No: S1400-MC4
- Inverters - Optimisers
- Phases: 1
- Specifically designed to work with SolarEdge Comercial inverters
- Mitigates all types of module mismatch loss, from manufacturing tolerance to partial shading
- Faster installations with simplified cable management and easy assembly using a single bolt
- Detects abnormal PV connector behavior, preventing potential safety issues
- Module-level voltage shutdown for installer and firefighter safety
- Flexible system design for maximum space utilization
- Compatible with bifacial PV modules
- Superior efficiency (99.5%)
Input Length:0.1m Output Length: 5.7m+ / 0.1m-
Note: S1400 Power Optimizers 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.
Important
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
