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 oversize my solar inverter?Oversizing your solar inverter would generally only occur for a few reasons. 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.
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.
How does a solar inverter affect efficiency?The efficiency of the inverter drives the efficiency of a solar panel system. Inverters change the Direct Current (DC) from solar panels into Alternating Current (AC), which is what we use in our homes and businesses. This article talks about how to pick the right size solar inverter.
How much should a solar inverter be undersized?The amount that you would want to undersize the inverter depends on the conditions that the system is installed in. Primarily, the DC-to-AC ratio, which is the ratio of DC current produced by the solar panels, versus the AC output of the inverter. In an undersized system, the DC-to-AC ratio will be greater than o
