SolarEdge 320W Power Optimizer w/ MC4 Compatible Connectors P320-5NC4ARS

Designed for fast, single bolt installation on high power 60-cell modules, the SolarEdge power optimizers maximize energy throughput from each and every module through constant tracking of Maximum Power Point (MPPT) individually per module. Automatically maintains a fixed string voltage, they allow optimal efficiency of the SolarEdge inverter and provide installers greater flexibility to design optimal PV systems for maximum space utilization. This flexibility mitigates effects from manufacturing tolerance, partial shading & orientation while allowing for multiple orientations, tilts and module types in the same string.

The SolarEdge power optimizers use next-generation module-level monitoring to ensure the performance of each panel and to communicate performance data to the SolarEdge monitoring portal. Each optimizer is equipped with the unique SafeDC™ feature which automatically shut down modules’ voltage whenever inverter or the grid power are shut down. All SolarEdge power optimizers have a 25-year manufacturer warranty.

System Design
Compatible Inverter Types:

• Single Phase HD-Wave
  • Minimum String Length: 8 optimizers
  • Maximum String Length: 25 optimizers
  • Maximum Power per String: 5,700W DC (6,000W DC with SE7600H-US)
• Single Phase
  • Minimum String Length: 8 optimizers
  • Maximum String Length: 25 optimizers
  • Maximum Power per String: 5,250W DC
• Three Phase 208V
  • Minimum String Length: 10 optimizers
  • Maximum String Length: 25 optimizers
  • Maximum Power per String: 6,000W DC
• Three Phase 480V
  • Minimum String Length: 18 optimizers
  • Maximum String Length: 50 optimizers
  • Maximum Power per String: 12,750W DC

A string with more than 30 optimizers does not meet NEC rapid shutdown requirements; safety voltage will be above the 30V requirement.
