The inverter loading ratio determines the amount of additional energy that can be cost-effectively sold. Generally, the maximum inverter loading ratio for solar + storage systems will have their output limited by:
For example, it is typical to see solar projects with 1.3 MW of PV panels per 1 MW of inverter capability. This oversizing of the PV panels in relation to the inverter size will maximize the total energy output of the system throughout the year, particularly during months with reduced solar irradiation.
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.
The DC to AC inverter ratio (also known as the Inverter Load Ratio, or “ILR”) is an important parameter when designing a solar project.
The project will be limited by the 100 MW interconnection and she has space to add up to 250 MW (DC) of panels, so economics will determine the best inverter loading ratio. To perform the analysis, she can follow these steps: Determine the amount of energy delivered at different inverter loading ratios.
Inverters will generally never output more than their max-rated AC power. During times when the DC input power is too high, the inverter will raise the operating voltage of the modules to pull the array off of its max power point and reduce the DC power. Why a 20% DC/AC ratio results in minimal clipping losses
