About How much over-capacity is appropriate for photovoltaic inverters
The main reason for oversizing an inverter is to drive it to its full capacity more often. Oversizing the inverter is not a requirement. An experienced PV designer might choose to oversize.
SolarEdge allows DC/AC oversizing depending on the inverter model. In most cases, you will require permission to operate an inverter larger than 3.68kW, which can be a good reference number for maximum AC power.

6 FAQs about [How much over-capacity is appropriate for photovoltaic inverters]
How many solar panels can a 3 kilowatt inverter have?
According to section 9.4 of of the Clean Energy Council’s Grid-Connected Solar PV Systems Design Guidelines the total panel capacity cannot exceed the total inverter capacity by more than one-third. So if you have a 3 kilowatt inverter you cannot have more than 4 kilowatts of solar panels and still receive the rebate/STCs.
What size solar inverter should I use?
While It’s generally not recommended to use an inverter that is significantly larger than the solar array’s capacity, a slight oversizing (e.g., using a DC-to-AC ratio of 1.2) can be beneficial. This approach can help reduce clipping losses and allow for future expansion of the solar array.
Why do solar panels have more capacity than inverters?
And the extra panel capacity can help the inverter to run at a higher average efficiency which can almost entirely make up for what is lost. When the total capacity of the solar panels is greater than that of the inverter the panels are usually said to be “oversized” or the inverter “overclocked”.
Can a solar array put out more power than an inverter?
According to the Clean Energy Council, you can have a solar array that can put out up to 30% more power than the inverter is rated for and remain within safe guidelines.
Does a solar PV system need an AC inverter?
The output of a solar PV system is dependent on the availability of the sun. Because the output of panels may only reach peak DC capacity a few hours out of the year, it may not be cost effective to size an AC inverter to capture that full output.
How much inverter capacity does a 10 kW solar array need?
Suppose you have a 10 kW solar array installed in a location with an ambient temperature of 35°C and an altitude of 1500 meters. Assuming an inverter efficiency of 95% and a derating factor of 0.9 (based on temperature and altitude), the required inverter capacity would be – AC Inverter Capacity = (10 kW / 0.9) / 0.95 = 11.76 kW
