1 March 2018 SolarEdge Inverter Efficiency, Europe & APAC Background Inverter efficiency is the ratio between inverter input power and inverter output power. High efficiency means lower losses, less heat to dissipate and higher reliability. Like all inverters, SolarEdge inverters are characterized by two efficiency values: Maximum efficiency – the highest inversion efficiency at which the inverter can operate. This efficiency is attained at a specific inverter working point, typically at 50% of peak power. Weighted efficiency – this efficiency takes into account the changing environmental conditions to which the inverter is exposed throughout the day and over the year and is calculated by measuring the inverter efficiency at various power loads.

SolarEdge Inverter Efficiency, Europe & APAC

Background

Inverter efficiency is the ratio between inverter input power and inverter output power. High efficiency means lower

losses, less heat to dissipate and higher reliability.

Like all inverters, SolarEdge inverters are characterized by two efficiency values:

Maximum efficiency – the highest inversion efficiency at which the inverter can operate. This

efficiency is attained at a specific inverter working point, typically at 50% of peak power.

Weighted efficiency – this efficiency takes into account the changing environmental conditions

to which the inverter is exposed throughout the day and over the year and is calculated by

measuring the inverter efficiency at various power loads. This efficiency provides a more

accurate inverter operating profile representation. The European weighting formula, optimized

for mainland Europe irradiance conditions, is:

𝜂 = 0.2 ∙ 𝜂100% + 0.48 ∙ 𝜂50% + 0.1 ∙ 𝜂30% + 0.13 ∙ 𝜂20% + 0.06 ∙ 𝜂10% + 0.03 ∙ 𝜂5%

The weighted efficiency of traditional inverters depends on inverter input voltage and is typically

measured for various voltages. Due to the fixed string voltage of the SolarEdge inverters they have

just one efficiency curve. All measurements were done at a nominal AC grid voltage of 230VL-N.

Efficiency Charts

The weighted efficiencies of the SolarEdge inverters are detailed in the inverter datasheets.

The efficiency curves of the SolarEdge inverters are shown below.
