Inverter is smaller than solar

Should I buy a larger solar inverter?

Maximise STCs: Purchasing a larger inverter might negate the savings you will receive on your STCs. A smaller inverter with maximised solar panels will attract a greater return when claiming the STCs. More efficient system: While a solar panel may be rated for 400W of solar production, the panels will not produce this 100% during daylight hours.

What does under-sizing a solar inverter mean?

Using the graph above as an example, under-sizing your inverter will mean that the maximum power output of your system (in kilowatts – kW) will be dictated by the size of your inverter. Solar inverter under-sizing (or solar panel array oversizing) has a become common practice in Australia and is generally preferential to inverter over-sizing.

What if my inverter is bigger than my solar array?

An inverter that is the same size (in kW) or larger than your solar array is being under-utilised. An inverter that is paired with a solar array of up to 33% higher powery will be operating at maximum power for longer each day. 2. Regulatory requirements But why a 6.6kW array of solar panels with a 5kW inverter?

How do I choose a solar inverter size?

To calculate the ideal inverter size for your solar PV system, you should consider the total wattage of your solar panels and the specific conditions of your installation site. The general rule is to ensure the inverter’s maximum capacity closely matches or slightly exceeds the solar panel array’s peak power output.
