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.
The optimization is similar to the one done for solar-only projects, with a minor increase in complexity to account for the state of charge of the energy storage. The inverter loading ratio determines the amount of additional energy that can be cost-effectively sold.
DC/AC ratio and inverter loading shape real solar yield more than most design choices. Set them well and you gain energy all year, keep the inverter in its high-efficiency zone, and leave headroom for grid support and batteries. This piece focuses on practical math, climate effects, and sizing ranges you can use today.
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.
