About Inverter AC DC ratio
Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25.
The only power generating component of the system is the PV array (the modules, also known as the DC power). For example a 9 kW DC PV array is rated to have the capacity to produce 9 kW of power at standard testing conditions (STC). STC is 1,000.
The inverter has the sole purpose of converting the electricity produced by the PV array from DC to AC so that the electricity can be usable at the property. Thus the nameplate.
A 9 kW DC solar array rarely produces this much power. The chart below actually shows ~4500 operating hours for a standard solar array.
When the DC/AC ratio of a solar system is too high, the likelihood of the PV array producing more power than the inverter can handle is increases. In the event that the PV array outputs.

6 FAQs about [Inverter AC DC ratio]
What is a good DC/AC ratio for a solar inverter?
Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25.
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.
What is DC/AC ratio?
The DC/AC ratio, also known as the DC to AC ratio, refers to the ratio between the direct current (DC) rated power of a photovoltaic (PV) array and the alternating current (AC) rated output of an inverter. DC/AC Ratio= PV Array’s DC Power (kW) / Inverter’s AC Power (kW)
What is DC & AC ratio in solar?
The DC and AC Ratio (also called Inverter Loading Ratio – ILR) is the ratio between the total installed DC capacity of solar panels and the AC capacity of the inverter. For example, if a solar plant has 10 MWp DC capacity and an 8 MW AC inverter, the ratio is 1.25. Q2. Why is DC and AC Ratio important in solar projects?
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).
What is the DC/AC ratio of a PV array?
This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25. The reason for this is that about less than 1% of the energy produced by the PV array throughout its life will be at a power above 80% capacity.
