It is best when the total capacity of your solar panels (DC size) is slightly bigger than the peak capacity of your inverters (AC size). To set up an efficient solar system, we recommend a DC-to-AC ratio of 1. Understanding this ratio helps you maximize your solar investment and ensure a stable, reliable energy supply. Why intentionally "undersize" your inverter? Solar panels. . Let's dive into step-by-step plans, on-the-ground numbers, and what influences inverter size. Know Your Total Solar Panel Capacity Begin by knowing your panel array capacity in watts (W).

What is solar inverter sizing?
Solar inverter sizing refers to choosing an inverter with the appropriate AC output for your solar panel system's DC input. It's about matching capacity and performance, without wasting energy or breaching local export limits. Inverter size is measured in kilowatts (kW). It should match your solar array within a 1.15 to 1.33 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.
How do I calculate the DC/AC ratio for my solar system?
To calculate the DC/AC ratio for your solar system, use this simple formula: Total Solar Panel Capacity (DC Watts) ÷ Inverter Capacity (AC Watts) DC/AC Ratio = 8000 ÷ 7000 = 1.14 This calculation helps ensure your inverter can handle the system's maximum DC power efficiently.
How much power does a solar inverter need?
This means your inverter doesn't need to power your entire home—it just converts whatever your panels generate. Let's say you have a 6kW solar array (twenty 300-watt panels). Your inverter needs to handle that 6kW of DC power, regardless of whether your home uses 2kW or 10kW at any given moment.
