Inverter Clipping
When solar panels produce more DC power than the inverter can convert to AC, the excess is clipped (wasted). Intentional with high DC/AC ratios to maximize morning/evening production at the cost of midday losses.
Why It Matters
A DC/AC ratio of 1.2-1.3 is standard, meaning some clipping occurs at peak sun. This design trade-off produces more total daily energy by boosting low-light hours.

DC/AC Ratio
The ratio of a solar array's DC panel capacity to the inverter's AC output rating. Typical residential values range from 1.1 to 1.35.
Clipping
When a solar inverter limits output because the DC input power from the panels exceeds the inverter's AC output rating. The excess energy is lost.
Maximum Power Point Tracking (MPPT)
An algorithm in solar inverters and charge controllers that constantly adjusts voltage and current extraction to keep panels operating at their maximum power output as conditions change.
