Inverter Clipping (Overclocking)
Category: science
The phenomenon where an inverter limits its power output to its maximum rated capacity, discarding excess solar energy.
Clipping occurs if the solar panel array’s peak output exceeds the inverter's maximum capacity (high DC-to-AC ratio). On sunny afternoons, the graph will show a flattened "clip" top line. While it looks like waste, oversizing the DC array ensures the inverter runs at peak capacity for longer hours.
Common Examples
- We engineered the system with a 1.3 DC-to-AC ratio, accepting minor mid-day inverter clipping to optimize early-morning generation loops.
- Excessive inverter clipping indicates your solar panel string is severely oversized relative to your centralized inverter engine engine size.
