SolarEdge DC Power Optimizer P400-5 Features:

A superior approach to maximizing the throughput of photovoltaic
systems using module embedded electronics:
  • Up to 25% increase in power output
  • Superior efficiency (99.5%) - peak performance in both mismatched and unshaded conditions
  • Flexible system design for maximum space utilization
  • Next generation maintenance with module level monitoring and smart alerts
  • Unprecedented installer and firefighter safety

The most cost effective solution for residential, commercial and

large field installations:
  • Module level MPPT - optimizes each module independently
  • Module-level monitoring for automatic module and string level fault detection allowing easy maintenance
  • Electric arc detection - reduces fire hazards
  • Unprecedented installer and firefighter safety mode - safe module voltage when inverter is disconnected or off
  • Allows parallel uneven length strings and multi-faceted installations
  • Immediate installation feedback for quick commissioning

The SolarEdge power optimizer is a DC/DC converter which is connected by installers to each PV module or embedded by module manufacturers, replacing the traditional solar junction box. The SolarEdge power optimizers increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. Furthermore, the power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring portal for enhanced, cost-effective module-level maintenance. Each power optimizer is equipped with the unique SafeDC™ feature which automatically shuts down modules' DC voltage whenever the inverter or grid power is shut down.

The MPPT per module allows for flexible installation design with multiple orientations, tilts and module types in the same string. When working with SolarEdge Inverters, SolarEdge power optimizers automatically maintain a fixed string voltage, allowing installers even greater flexibility with longer strings and strings of different lengths in order to design optimal PV systems. Alternatively, the new independent optimization (IndOP™) technology, available with OPA model power optimizers, allows power optimizers to be installed without the need for additional interface hardware and to operate directly with any inverter. The SolarEdge power optimizers are compatible with c-Si and thin-film modules and have a 25 year warranty.
