6 FAQs about [Load carried by DC panel inverter]
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.
Why are solar developers increasing inverter loading ratios?
Hourly level solar data are insufficient to fully capture the magnitude of clipping. Due to decreasing solar module prices, some solar developers are increasing their projects’ inverter loading ratio (ILR), defined as the ratio of DC module capacity to AC inverter capacity. In this study, we examine the operational impacts of this trend.
What is inverter load ratio (ILR)?
We use the term inverter loading ratio (ILR) to describe this ratio of the array’s nameplate DC power rating to the inverter’s peak AC output rating. Other commonly-used terms include DC/AC ratio, array-to-inverter ratio, inverter sizing ratio, and DC load ratio, among others .
What is inverter loading ratio?
In this study, the inverter loading ratio is defined as: (1) ILR = P d c, peak P a c, peak where Pdc,peak is the maximum rated module power output for all modules in all strings at standard test conditions and Pac,peak is the inverter’s maximum AC power output.
How much energy is delivered by increasing inverter loading ratio?
Determine how much energy is delivered for each increase in inverter loading ratio. For example, if the total energy delivered for a 1.6 inverter loading ratio is 254,400 MWh and for a 1.7 inverter loading ratio is 269,600 the marginal change in energy delivery is 269,600 MWh - 254,400 MWh = 15,200 MWh.
Can a module rated power be bigger than an inverter rated?
We all know that the module rated power can be larger than the inverter rated power (within reason—inverters do have a max input current). But far fewer designers and engineers understand what are the practical limits. The DC to AC ratio (also known as the Inverter Load Ratio, or “ILR”) is an important parameter when designing a solar project.
