SolarEdge P400 400W Optimizer

SKU: 565-0206

SolarEdge, Optimizer 400W, Add-On Box for one 72 or 96 cell module, 8-80V, 10.1A, MC4-compatible In/Out, 47" PV wire, UL 1000VDC, P400

The P400-5NC4ARM is designed for the next generation of high-power modules, enhanced inventory management, faster installation, and compliance with the VDE-AR-E 2100-712 Fire Protection Standard, in addition to the benefits of existing power optimizers, such as added capacity, modular design, module-level control, and safety. The electrical ratings, functionality, and mechanical interface of 5-Series power optimizers are identical to those of 2-Series power optimizers. Power optimizers from the 5 and 2 series can be used interchangeably. In comparison to the 2-Series, the 5-Series power optimizers are IP68/NEMA6P rated and have smaller mechanical dimensions.

Each module is connected to the SolarEdge power optimizer, which replaces the conventional solar junction box. Via constant monitoring of the Maximum Power Point per module, each power optimizer maximizes energy production from each and every module. Furthermore, the power optimizers track each module's output and send data to the SolarEdge monitoring portal for more efficient, cost-effective maintenance. When operating with SolarEdge inverters, power optimizers automatically maintain a set string voltage, enabling the SolarEdge inverter to operate at optimum efficiency and allowing installers to build more efficient PV systems.

Independent optimization (IndOP™) technology enables power optimizers to be mounted without external interface hardware and to work with any inverter. When the inverter or grid power is turned off, the SafeDC™ feature on each power optimizer automatically shuts down the voltage of the modules.


  • Maximum Power Point Tracking on a Module-by-Module Basis (MPPT)
  • The superior efficiency of up to 25% more electricity (99.5 percent peak efficiency, 98.8 percent weighted efficiency)
  • From manufacturing tolerance to partial shading, all forms of module mismatch-loss are mitigated.
  • Crafted to withstand harsh environmental conditions
  • For optimum space usage, a flexible device design is used.
  • 25-year warranty and dependability
  • Module-level control and advanced, real-time output measurement
  • Installer and firefighter protection is assured by an automatic module DC voltage shut-down.
  • With a single bolt, installation is simple and fast.

Optimized for Present and Future PV Module Ratings

  • The 5-Series power optimizers provide the superior matching between power optimizer and PV module ratings (power, voltage, and current): P300 power optimizers match 60-cell crystalline PV modules
  • P320 power optimizers match high-power 60-cell crystalline PV modules
  • P370 power optimizers match higher-power 60 and 72-cell crystalline PV modules
  • P400 power optimizers match 72-cell and 96-cell crystalline PV modules
  • P405 power optimizers match high-voltage thin-film PV modules for residential installations
  • P505 power optimizers match higher voltage, 96-cell crystalline PV modules for residential installations
  • P600 power optimizers match 60-cell crystalline PV modules, two modules connected in series for commercial installations
  • P700 power optimizers match 72-cell crystalline PV modules, two modules connected in series for commercial installations
