Technical FAQs 4
How much wattage does a solar inverter need?
A good rule of thumb is to multiply the total wattage of your solar panels by 1.25 to account for inefficiencies and potential load spikes. For example, if you have a 5 kW solar system, you would need an inverter rated for at least 6.25 kW. Q: What happens if my inverter is too small for my solar panel system?
How do you size a solar inverter?
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.
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
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.
