FAQS 4

How big should a solar inverter be?

To account for power losses assume an 80 percent efficiency. Your solar inverter should have a similar or slightly higher wattage rating than the DC output of your solar panels (which in this case is 4.5 kW). You can size it between 1.15 and 1.5 times larger. The rule of thumb is to size your inverter 1.25 bigger than your solar array.

How do I choose a solar inverter?

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.

Do solar inverters need a minimum voltage?

Solar inverters require a minimum input voltage to function effectively. If your solar panel array doesn’t generate enough power—say, during cloudy weather or early morning—the inverter might not even turn on. This results in missed opportunities to capture available energy. 3. System Longevity and Reliability

Why is inverter size important?

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).
