SolarEdge P300 Power Optimizer

ID: P300



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

P-Series Module Add-On Power Optimizers

Connected by installers to the PV module and compatible with a wide range of modules

Power Optimizer Model    Module Power  Module Voc  Current
P300 ≤300W ≤48V 10A
P320 ≤320W ≤48V 11A

P-Series Commercial Power Optimizer

Commercial solution connecting two modules per power optimizer

Power Optimizer Model    Module Power  Module Voc  Current
≤800W* ≤83V 14A
P800s ≤800W* ≤120V 12.5A

* Rated combined STC power of 2 modules connected in series (for the P800p, connected in parallel). Module of up to +5% power tolerance allowed.
** Dual input for parallel connection of two modules; single input version is available and should be used when connecting a single module to the power optimizer (in case of odd number of modules in the string)
