6 FAQs about [Maximum capacity ratio of photovoltaic 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.

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.

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.

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.

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 you calculate array to inverter ratio?

To get the array to inverter ratio, you must divide the array’s DC rating by the inverter’s maximum AC output. For example: Most solar systems fall between 1.15 to 1.25 array-to-inverter ratio. As long as you fall below the 1.33 recommended maximum array-to-inverter ratio, then your solar system is working optimally.
