What are Australia's New inverter installation rules?

The upcoming inverter installation rules represent a major shift in the regulatory landscape for distributed energy systems in Australia. With a focus on safety, flexibility, and grid stability, the new guidelines encourage responsible growth of solar and battery technology.

How many solar panels can an inverter run in Australia?

Rule of thumb: In Australia, PV array capacity is commonly allowed up to 133% of inverter AC rating for STC eligibility (check current CER guidance). Oversizing helps the inverter run near its sweet‑spot more often. Example: A 5 kW inverter with up to ~ 6.6 kW of panels is standard.

What size solar inverter do I Need?

The inverter should closely match your panel capacity (80-100% of the array size). For example, if you install a 6 kW solar PV system, you’ll need a minimum 5 kVA inverter. When you install your solar system, your solar provider should discuss inverter options with you, as well as assess your system to determine which size inverter you need.

How many solar panels can I install with a 5kw inverter?

So for all practical purposes the 5kW inverter size limit applies to most single phase households. But even with a 5kW 'system size limit' you may well be able to install up to 10kW of panels! How? By oversizing your solar panel array relative to your inverter as described here.
