Inverters come in different sizes starting from as little as 125 watts. The typical inverter sizes used for residential and commercial applications are between 1 and 10kW with 3 and 5kW sizes being the most common. With such an array of options, how do you find the right size for you? An inverter works best when close to its capacity.
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.
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.
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).
