What does under-sizing a solar inverter mean?

Using the graph above as an example, under-sizing your inverter will mean that the maximum power output of your system (in kilowatts – kW) will be dictated by the size of your inverter. Solar inverter under-sizing (or solar panel array oversizing) has a become common practice in Australia and is generally preferential to inverter over-sizing.

What does oversizing a solar inverter mean?

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?

Can a solar inverter be matched with a rooftop solar panel?

Inverter sizes (kW) can be efficiently matched with rooftop solar panel array sizes (kW) that are up to 33% bigger. There are a couple of reasons for this. 1. Getting the best value from your inverter The inverter converts the DC power from the solar panels into AC power that can be used in the house or sent to the grid.
