Let’s get started!

What is a 6.6kW Solar System with a 5kW Inverter?

A 6.6kW solar system consists of a set of solar panels that together generate 6.6 kilowatts of electricity. The solar panels convert sunlight into direct current (DC) electricity. The 5kW inverter then converts this DC power into alternating current (AC), the form of electricity your home uses.

The inverter sizing is a key aspect of solar system efficiency. In Australia, a 5kW inverter paired with a 6.6kW solar system is a common configuration due to the Clean Energy Council’s allowance for oversizing—the process of using an inverter that is slightly smaller than the total panel output. This setup optimizes the system’s performance, particularly in varying weather conditions, and ensures energy is generated efficiently.
