FAQs 6

Do solar inverters have a rated capacity?

Ratings on solar inverters often give the false impression that you can connect as many panels as you like, as long as you’re under the stated power output. This leads to a misconception that exceeding the rated capacity is acceptable if you distribute loads wisely.

Do higher DC/AC ratios improve inverter utilization?

Higher DC:AC ratios always improve inverter utilization and the capacity factor. The measurement of inverter utilization is capacity factor—the ratio between actual and maximum energy production. A significant portion of system cost is tied to the AC rating of the inverter (string or microinverter).

What happens if a power inverter's DC/AC ratio is not large?

The following illustration shows what happens when the power inverter’s DC/AC ratio is not large enough to process the higher power output of mid-day. The power lost due to a limiting inverter AC output rating is called inverter clipping (also known as power limiting).

How do I choose a solar inverter?

When designing a solar installation, and selecting the inverter, we must consider how much DC power will be produced by the solar array and how much AC power the inverter is able to output (its power rating).

What is a good inverter load ratio?

At the end of 2016, the United States had 20.3 gigawatts (GW) AC of large-scale photovoltaic capacity in operation with a DC module rating of 25.4 GW, resulting in a capacity-weighted average ILR of 1.25. For individual systems, inverter loading ratios are usually between 1.13 and 1.30.

What is the average solar inverter loading ratio?

Inverter loading ratios are higher for larger solar power plants. At the end of 2016, smaller plants—those one megawatt (MW) or less in size—had an average ILR of 1.17, while larger plants—those ranging from 50 MW to 100 MW—had an ILR of 1.30. As solar plants have gotten larger, inverter loading ratios have increased.
