If a PV array has a rated DC capacity of 12kW and the inverter has an AC rated output of 10kW, the DC/AC ratio would be 1.2. What Is the Ideal DC/AC Ratio? In most cases, the ideal DC/AC ratio typically ranges between 1.2 and 1.4. However, the optimal value can vary based on local climate conditions, equipment costs, and specific project goals.
The DC and AC Ratio (also called Inverter Loading Ratio – ILR) is the ratio between the total installed DC capacity of solar panels and the AC capacity of the inverter. For example, if a solar plant has 10 MWp DC capacity and an 8 MW AC inverter, the ratio is 1.25. Q2. Why is DC and AC Ratio important in solar projects?
The Clipping Trade-Off: The one downside of a high DC to AC ratio is a phenomenon called "clipping." This occurs on bright, sunny days when the solar panels produce more DC power than the inverter''s maximum AC output. The inverter "clips" the excess power, meaning that energy is lost.
The DC to AC Ratio —also known as the Inverter Loading Ratio (ILR) —is the simple yet powerful relationship between: AC capacity: the inverter’s maximum power output (in Watts or kW<sub>ac</sub>). Formula: For example, a 9 kW_DC solar array connected to a 7.6 kW_AC inverter gives: 1. Better Use of Inverters
