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.
Step-by-Step Calculation of Inverter Capacity The first step is to calculate the total DC capacity of the solar array. As shown earlier, this is done by multiplying the number of panels by the wattage of each panel. Example: Select an appropriate DC to AC ratio based on the system design.
Solar inverter sizing refers to choosing an inverter with the appropriate AC output for your solar panel system’s DC input. It’s about matching capacity and performance, without wasting energy or breaching local export limits. Inverter size is measured in kilowatts (kW). It should match your solar array within a 1.15 to 1.33 ratio.
A DC to AC ratio of 1.3 is preferred. System losses are estimated at 10%. With a DC to AC ratio of 1.3: In this example, an inverter rated at approximately 10.3 kW would be appropriate. Accurately calculating inverter capacity for a grid-tied solar PV system is essential for ensuring efficiency, reliability, and safety.
