Power Optimiser Panel Add-on

The SolarEdge power optimiser is a DC/DC converter which is connected by installers to each solar panel, turning them into smart panels. The SolarEdge power optimisers increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each panel individually. Furthermore, the power optimisers monitor the performance of each panel and communicate performance data to the SolarEdge monitoring platform for enhanced, cost-effective panel-level maintenance. Each power optimiser is equipped with the unique SafeDC™ feature which automatically reduces panels' 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 panel allows for flexible installation design with multiple orientations, tilts and panel types in the same string.  When working with SolarEdge inverters, the power optimisers 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 optimisers are compatible with c-Si, thin-film, and high current panels, and have a 25-year warranty.

The following power optimiser models are available:

P300-P505 Power Optimiser

Connected by installers to the PV panel and compatible with a wide range of panels

Power Optimiser Model

Panel Power

Panel Voc 

Typical Panel Compatibility




60-cell panels




High power 60-cell and 72-cell panels


≤500W ≤80V 96-cell panels




60-cell and 72-cell, short strings 
P505 ≤505W ≤83V High current panels including bifacial panels

* Also available with frame mounted bracket; can be mounted in advance for quicker installation. Download datasheet
** Dual input for parallel connection of two panels; single input version is available and should be used when connecting a single panel to the optimiser (in case of odd number of panels in the string or when using panels that are compatible only in a single-panel configuration)


P600-P850 Commercial Power Optimisers

Commercial solution connecting two panels per power optimizer, for lower installation costs

Power Optimiser Model

Panel Power

Panel Voc

Typical Panel Compatibility




2 x 60-cell PV panels




2 x 72-cell PV panels

P800p (for parallel connection)**



Parallel connection of 2 x 96-cell 5’’ PV panels

P800s (for series connection)



Series connection of 2 x high power or bi-facial panels
* Rated combined STC power of 2 panels connected in series. Panel of up to +5% power tolerance allowed.
** Dual input for parallel connection of two panels; when connecting a single panel to the optimiser (in case of odd number of panels in the string) seal the unused input connectors with the supplied pair of seals.
