Oversizing your solar system generally means that your solar inverter is oversized for the amount of solar panels and energy output you currently have. An example of this would be if you have 4kW of solar panels but a 5kW solar inverter. Why would I oversize my solar inverter?
Maximise STCs: Purchasing a larger inverter might negate the savings you will receive on your STCs. A smaller inverter with maximised solar panels will attract a greater return when claiming the STCs. More efficient system: While a solar panel may be rated for 400W of solar production, the panels will not produce this 100% during daylight hours.
If an inverter is under-sized, this should happen within certain parameters – which accredited solar installers will be familiar with. Regardless of the output of the solar panels, the power output will be cut off (‘clipped’) by the inverter so that it does not exceed the inverter’s rated capacity (e.g. 3kW, 5kW etc).
The efficiency of the inverter drives the efficiency of a solar panel system. Inverters change the Direct Current (DC) from solar panels into Alternating Current (AC), which is what we use in our homes and businesses. This article talks about how to pick the right size solar inverter.

Undersizing a solar system inverter is a smart choice when building a solar system because that actually increases the daily amount of power produced.
What is inverter clipping Inverter clipping occurs when the DC input from the solar panels exceeds the AC power capacity of the inverter. At that moment the inverter limits its …
Conversely, selecting an oversized inverter might seem beneficial at first glance, but it can lead to inefficiencies. Oversized …
The system efficiency of your solar power system can be impacted by under-sizing or over-sizing your inverter. What are the implications of having solar panel capacity larger or …
An inverter is an essential component of a solar panel system as it converts the direct current (DC) electricity generated by the solar panels into alternating current (AC) …
Conversely, selecting an oversized inverter might seem beneficial at first glance, but it can lead to inefficiencies. Oversized inverters operating at lower power outputs could …
Undersizing an inverter can lead to inverter clipping, where the inverter is unable to handle the maximum output of the solar panels. This occurs when there is more DC power …
