Inverter size also plays a key role in the DC-to-AC ratio—a critical design metric in any solar system. This ratio compares the total power rating of your solar panels (in DC) to the maximum output of your inverter (in AC).
Below, we’ll walk through the three essential steps for sizing your solar inverter properly. Your first step is understanding how much power your solar panels will produce—this is known as your solar array size. It’s typically measured in kilowatts (kW) and calculated by summing up the wattage of all your solar panels.
It’s a common misconception that a larger inverter automatically means better performance. In reality, an oversized solar inverter may not operate efficiently if your solar array doesn’t consistently produce enough energy to utilize that capacity.
Knowing your array size allows you to choose an inverter that can handle that production efficiently—without over- or under-investing in capacity. The second step is understanding your system’s DC-to-AC ratio, one of the most important metrics when sizing a solar inverter.
