SolarEdge P505 Power Optimiser

The SolarEdge power optimizer is a DC/DC converter which is connected by installers to each solar module, turning them into smart modules. 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 platform for enhanced, cost-effective module-level maintenance. Each power optimizer is equipped with the unique SafeDC™ feature, which is designed to automatically reduce modules' DC voltage to a safe level whenever the inverter or grid power is shut down (unless connected to a StorEdge inverter operating in backup mode).

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, the 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. The SolarEdge power optimizers are compatible with c-Si, thin-film, and high current modules and have a 25- year warranty.

Power Optimizer Model

Module Power Module Voc Typical Module Compatibility
P300* ≤300W ≤48V 60-cell modules
P370* ≤370W ≤60V High power 60-cell and 72-cell modules
P500* ≤500W ≤80V 96-cell modules
P404* ≤405W ≤80V 60-cell and 72-cell, short strings
P505 ≤505W ≤83V High current modules including bi-facial modules
P405** ≤405W ≤125V Thin film modules
* Also available with frame mounted bracket; can be mounted in advance for quicker installation.
** Dual input for parallel connection of two modules; single input version is available and should be used when connecting a single module to the optimizer (in case of odd number of modules in the string or when using modules that are compatible only in a single-module configuration)
