About DC utilization of inverter
DC/AC ratio, also called inverter loading ratio (ILR), is the array’s STC power divided by the inverter’s AC nameplate power. ILR = P DC, STC / P AC, rated. A higher ILR feeds more energy during long shoulder hours and in winter, at the cost of some midday clipping on clear, cool days.

6 FAQs about [DC utilization of inverter]
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 is DC voltage utilization ratio?
In addition to having fewer components and higher efficiency, the dc voltage utilization ratio of the inverter is 2.5 times that of the traditional inverter such as Neutral Point Clamped (NPC), FC, and Active NPC (ANPC).
Do Enphase microinverters have a DC/AC Ratio limit?
Enphase Microinverters have no DC:AC ratio input limit aside from DC input voltage and current compatibility. 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.
What is DC to AC inverter ratio?
The DC to AC inverter ratio (also known as the Inverter Load Ratio, or “ILR”) is an important parameter when designing a solar project.
How much voltage can an inverter output?
The inverter can output a fundamental voltage four times the dc-link voltage. However, there is no doubt that with the increase of the dc sources number, the cost of the entire system will increase significantly.
How do inverters convert DC voltage to AC voltage?
Most inverters rely on resistors, capacitors, transistors, and other circuit devices for converting DC Voltage to AC Voltage. In alternating current, the current changes direction and flows forward and backward. The current whose direction changes periodically is called an alternating current (AC). It has non-zero frequency.
