FAQs 6

What is a good DC/AC ratio for a solar inverter?

If a PV array has a rated DC capacity of 12kW and the inverter has an AC rated output of 10kW, the DC/AC ratio would be 1.2. What Is the Ideal DC/AC Ratio? In most cases, the ideal DC/AC ratio typically ranges between 1.2 and 1.4. However, the optimal value can vary based on local climate conditions, equipment costs, and specific project goals.

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 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 the DC/AC ratio of a PV array?

DC/AC Ratio= PV Array’s DC Power (kW) / Inverter’s AC Power (kW) If a PV array has a rated DC capacity of 12kW and the inverter has an AC rated output of 10kW, the DC/AC ratio would be 1.2. What Is the Ideal DC/AC Ratio? In most cases, the ideal DC/AC ratio typically ranges between 1.2 and 1.4.

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 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.
