SolarEdge S1200 Power Optimizer (Short Input 0.1m)
- S1200 Power Optimizer (Short Input 0.1m)
- Part No: S1200-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: 5.3m+ / 0.1m-
Note: The S1200 has a higher operating current. When pairing the S1200 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). The applicable inverter Part Numbers are as follows: SExxK-xxxxIxxCx, SExxK-xxxxIxxDx, SExxK-TWxxIxxLx, SExxK-xxxxIxxZx
