1. Understanding Inverter Capacity The capacity of an inverter is the maximum power output it can handle, usually measured in kilowatts (kW) or kilovolt-amperes (kVA). The goal is to match the inverter capacity with the solar array's size (in terms of power output) and the load (electricity demand) to ensure optimal performance.
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.
Inverters are usually sized lower than the kilowatt peak (kWp) of the solar array because solar panels rarely achieve peak power. The solar array-to-inverter ratio is calculated by dividing the direct current (DC) capacity of the solar array by the inverter's maximum alternating current (AC) output.
The size of a solar inverter is crucial because it determines how much energy can flow to your home and battery at any given time. More specifically, the inverter ensures that enough energy can flow from your solar panels to the grid and load or if installed with a battery, from and to the battery.
The required inverter capacity is determined by dividing the total DC power by the DC to AC ratio. Example: With a total DC capacity of 8.4 kW and a DC to AC ratio of 1.2: In this case, you would select a 7 kW inverter to efficiently convert the solar array’s DC power to AC. 5. Considering System Losses
Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25.
