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 the array-to-inverter ratio of a solar panel system?

The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1. If you install the same-sized array with a 5000 inverter, the ratio is 1.2.

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.

Why should you choose a DC/AC ratio for a solar PV system?

This setup achieved a 12% increase in annual energy production, with only 2% clipping losses, delivering the best overall economic return. Designing the right DC/AC ratio is crucial for maximizing the efficiency, lifespan, and profitability of a solar PV system.

Can a solar inverter be bigger than the DC rating?

The size of your solar inverter can be larger or smaller than the DC rating of your solar array, to a certain extent. The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1.

What ratio should a 5000 inverter have?

If you install the same-sized array with a 5000 inverter, the ratio is 1.2. Most installations will have a ratio between 1.15 to 1.25; inverter manufacturers and solar system designers typically do not recommend a ratio higher than 1.55. Below are some examples of solar inverter products and their maximum DC power output recommendation:
