SolarEdge Residential Solution

How Does Solar Energy Work?

Every hour, more energy is produced by the Sun than all of us in the world could use in a whole year — clean, limitless, free energy.
SolarEdge helps you harvest this energy to power your home.
Solar photovoltaic (PV) modules, capture, and convert sunlight into clean DC (direct current) electricity. A solar inverter converts the DC electricity into grid compliant AC (alternating current) that powers your home.


Traditional PV Inverters

Traditional PV systems consist of PV modules wired together in a series, much like Christmas tree lights. If a single module underperforms for any reason (cloud-cover, dust or dirt for example), the rest of the modules on that string also underperform, reducing energy production across the whole string.

The SolarEdge PV Solution

In a SolarEdge installation, each PV module is connected to an intelligent electronic chip called a power optimizer. Power optimizers maximize solar energy production from each module separately and therefore reduce power losses. If an individual module underperforms, it won’t affect the performance of any of the other modules in the string. Every SolarEdge system further benefits from advanced monitoring that tracks and reports the performance of every module, and exceptional safety features. A suite of integrated smart energy solutions further maximize your energy production and energy savings.

More power equals more revenue and more savings on electricity bills. In traditional string inverter systems, one underperforming module reduces the performance of an entire string.

With SolarEdge, each module produces at its maximum ability at all times, ensuring greater energy yield from the entire system.

Advanced Safety

With millions of photovoltaic (PV) systems installed worldwide, this technology is designed to be
relatively safe and reliable. However, as traditional PV installations can reach voltages as high as
1,500VDC, precautions should be taken to ensure the safety of people and assets.
With traditional inverters, shutting down the inverter or the grid connection will terminate current flow, but DC voltage in the string cables will stay high for as long as the sun is shining.
In addition, electrical arcs, which can result in a fire, create a threat to people and assets in the vicinity of the PV system.
The SolarEdge system provides a superior safety solution for both electrocution and fire risks.


SafeDC™ is a built-in module-level safety feature which minimises electrocution risk. To maintain string voltage below risk levels, power optimizers are designed to automatically switch into safety mode, in which the output voltage of each module will be reduced to a safe level in either of these cases:
During installation, when string is disconnected from the inverter, or the inverter is turned off
During maintenance or emergency, when the inverter or AC connection is shut down
When the thermal sensors of the power optimizers detect a temperature above 85 ˚C
The SolarEdge SafeDC™ feature is certified in Europe as a DC disconnect according to
IEC/EN 60947-1 and IEC/EN 60947-3 and to the safety standards VDE AR 2100-712 and OVE R-11-1.
