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.
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.
Should I install an inverter on my solar panel array?
Installing an inverter whose maximum capacity is greater than the nominal capacity of your solar panel array may be an option if you’re looking to expand your solar panel array at some point in the future, but it is not generally recommended.
Can I add a solar inverter to my solar system?
Adding to your solar system in the future: You may plan to add additional solar panels at a later date. Oversizing your inverter allows more capacity to be installed when you need it. Space limitations: If you plan to increase your solar capacity at a later date, you may not be able to fit 2 or more inverters in the future.
Should a solar inverter be under-sized?
Solar inverter under-sizing (or solar panel array oversizing) has a become common practice in Australia and is generally preferential to inverter over-sizing. If an inverter is under-sized, this should happen within certain parameters – which accredited solar installers will be familiar with.
Should solar panels have a smaller inverter size?
To a case in point, we quite regularly see systems that have a smaller inverter size than solar panel size for cost and performance maximisation and where we have components that are ideally matched. For example, a 315 Watt (DC) LG Neon solar panel matched to an Enphase 250 Watt (AC) inverter.
