SolarEdge Power Optimizers UK

The SolarEdge power optimizer is a DC/DC converter which is connected by installers to each solar 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. Alternatively, the new independent optimization (IndOP™) technology, allows power optimizers to be installed without the need for the additional interface hardware and to operate directly with any inverter. The SolarEdge power optimizers are compatible with c-Si and thin-film modules and have a 25-year warranty.

Why Retrofit SolarEdge to your Solar PV System?

Many solar PV systems underperform throughout their lifetime, costing the owner lost energy and money. While the variances between solar PV panels have improved over the years, there are a number of factors that can cause a panel to lose their efficiency, impacting the array of PV panels it's connected to, including:

  • Dirty or degraded panels
  • Partial shading (this could be caused by trees, a chimney, or a number of other factors)
  • Manufacturing tolerances between panels
  • Temperature variants

Generate More Electricity

Solar pv panels using a traditional string system can impact your electricity yield from your solar pv system. Due to the nature of the design, the lowest-performing panel limit will the efficiency of the other panels to that panel. For example, if one panel was shaded by a tree and therefore at 50% efficiency, the rest of the panels would also be at 50% efficiency. The higher the mismatch between the solar pv panels, the greater the energy that can be retrieved and, therefore, the more significant the savings gained by retrofitting a SolarEdge system.

Improved Safety

Solar PV systems are safe and recent technological advancements have made them even safer. Due to the nature of Solar PV system cables carrying high voltages from the PV panels, SolarEdge provides further safety with its SafeDC™ feature. Designed to reduce the system to 1 volt per module when the AC power has been shut off, this safety system protects your property when maintenance is being done on your Solar PV system.


SolarEdge enabled real-time monitoring of your PV panels using the monitoring platform. Instantly check the performance of your panels and set up automatic alerts if the system encounters any issues. SolarEdge inverters come with a long-term warranty, with owners able to enjoy 12-years peace of mind which can be further extended to 20 or 25 years. Each SolarEdge power optimiser also comes with a 25-year warranty as standard.


By installing SolarEdge, you're future-proofing your home energy solutions. SolarEdge can help towards seamless upgrades to your home battery storage, smart home capabilities, EV charging and any other upgrades that may come in the future. SolarEdge will help towards the maximum utilisation of your existing Solar PV panels, helping save you money and reduce your reliance on the grid.
