Defined term
Inverter clipping
Inverter clipping occurs when available direct-current photovoltaic power exceeds the inverter's ability to convert and deliver alternating-current power at that moment.
Also known as PV clipping loss

Definition and boundaries
Definition
Inverter clipping occurs when available direct-current photovoltaic power exceeds the inverter's ability to convert and deliver alternating-current power at that moment.

In plain language
When comparing Inverter clipping, keep the unit, time period, measurement boundary, and underlying assumptions the same on both sides.
What it is not
It is not every difference between direct-current nameplate capacity and alternating-current energy output.
Decision context
Why it matters
Clipping depends on array-to-inverter sizing, irradiance, temperature, inverter limits, orientation diversity, and time resolution; some clipping can coexist with higher annual inverter utilization.
