Power Optimisers
The SolarEdge power optimiser is a DC/DC converter which is connected by installers to each PV panel or embedded by panel manufacturers, replacing the traditional solar junction box. 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 portal for enhanced, cost-effective panel-level maintenance. Each power optimiser is equipped with the unique SafeDC™ feature which automatically shuts down panels' DC voltage whenever the inverter or grid power is shut down.
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, SolarEdge 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 and thin-film panels and have a 25-year warranty.
The following power optimiser models are available:

* Also available with frame mounted bracket; can be mounted in advance for quicker installation.
** 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-P800 Power Optimiser
The P600-P800 commercial solution for connecting two panels per power optimiser.
