FAQs 6

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.

Is there a difference between inverter size and solar panel capacity?

However, this should always be within the recommended ratio. This is the reason why you may see a ‘mismatch’ between inverter size and solar panel capacity – for example, a 6.6kW system advertised with a 5kW inverter.

What size solar inverter do I Need?

Inverter size is measured in kilowatts (kW). It should match your solar array within a 1.15 to 1.33 ratio. Getting it wrong can reduce efficiency or disqualify you from solar rebates. What size inverter do I need for solar panels? To calculate, divide your solar panel system’s total DC rating by the desired inverter’s AC output.

Why is there a'mismatch' between inverter size and solar panel capacity?

This is the reason why you may see a ‘mismatch’ between inverter size and solar panel capacity – for example, a 6.6kW system advertised with a 5kW inverter. It’s critical for an oversized system to remain within the correct ratio, as this not only impacts efficiency, but also your eligibility for government solar incentives.

How do I calculate a solar panel inverter ratio?

To calculate, divide your solar panel system’s total DC rating by the desired inverter’s AC output. This gives you the array-to-inverter ratio: For example: Within the ideal range (up to 1.33) set by many regulatory bodies, like Australia’s Clean Energy Council.

Can a solar inverter be bigger than the DC rating?

The size of your solar inverter can be larger or smaller than the DC rating of your solar array, to a certain extent. 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.
