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.
How do I choose the right solar inverter size?
The size of your solar array is the most crucial factor in determining the appropriate inverter size. The inverter’s capacity should match the DC rating of your solar panels as closely as possible. For instance, if you have a 5 kW solar array, you would typically need a 5 kW inverter. Array-to-Inverter Ratio
