SolarEdge: The science bit…

Published: August 8, 2023

Our inverter and power optimisers were the game changer in how solar energy power is managed and harvested.

Power Optimisers

The SolarEdge Power Optimiser is an AC/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 is designed to automatically reduce the modules’ DC voltage to a safe level whenever the inverter or grid power is shut down (unless connected to a SolarEdge inverter operating in backup mode).
The SolarEdge system is the only system that includes a panel-level cloud-based monitoring platform, which you can access from your mobile phone.

Per-module Maximum Power Point Tracking

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 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 modules and come with a 25 year warranty as standard.

Technical benefits

  • Per-module Maximum Power Point Tracking (MPPT)
  • Superior efficiency (99.5% peak efficiency, up to 98.8% weighted efficiency)
  • Mitigates all types of modules’ mismatch-loss, from manufacturing tolerance, partial shading and ageing
  • Designed for extreme environmental conditions
  • 25-year reliability and warranty
  • Advanced, real-time performance measurement
  • Automatic module DC voltage shutdown for installer and firefighter safety
  • Connected by installers to c-Si, thin-film, and high current (including bi-facial) modules
