Technical FAQs 4

Do solar panels need a larger inverter?

In the past, virtually all solar systems featured panels and an inverter of equal capacity. Now many installers recommend having an array of panels with a holding power larger than that of your inverter. This is called inverter oversizing.

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?

How does a solar inverter affect efficiency?

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.

How much solar power can a 5kw inverter produce?

Under the Clean Energy Council rules for accredited installers, the solar panel capacity can only exceed the inverter capacity by 33%. That means for a typical 5kW inverter you can go up to a maximum of 6.6kW of solar panel output within the rules.
