6 FAQs about [Differences in the size of photovoltaic inverters]

Are solar inverters the same size?

No, solar inverters are not the same size, as the size you need will depend on the generation capacity of your solar array. There is no one-size-fits-all inverter, as the size affects the unit’s efficiency and larger inverters are more expensive. The easiest way to calculate the solar inverter size you need is to check the DC rating.

How to choose a solar inverter?

The following points need to be considered before you choose your size and start the solar inverter installation process: The size of your solar system or array is the main determining factor in the size of your inverter. This is because the inverter converts the array’s DC electricity into your home’s AC requirement.

What size solar inverter do I Need?

However, oversizing the array is a common practice for maximum efficiency, and a 6.6kW solar PV system typically comes with a 5kW inverter. The typical climate and sunlight available throughout the day will impact the ideal inverter capacity. The positioning of your solar PV system will also affect the solar inverter size you need to purchase.

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 determine a solar inverter size?
