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.
The PV module capacity and solar inverter capacity ratio are commonly referred to as capacity ratio. Reasonable capacity ratio design needs to be considered comprehensively in the light of the specific project.
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:
Inverter size is measured in kilowatts (kW). It should match your solar array within a 1.15 to 1.33 ratio. Getting it wrong can reduce efficiency or disqualify you from solar rebates. What size inverter do I need for solar panels? To calculate, divide your solar panel system’s total DC rating by the desired inverter’s AC output.
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.
To calculate, divide your solar panel system’s total DC rating by the desired inverter’s AC output. This gives you the array-to-inverter ratio: For example: Within the ideal range (up to 1.33) set by many regulatory bodies, like Australia’s Clean Energy Council.
