Let’s say you have a 5kW solar system and you’re using an inverter with 92% efficiency. That means you’re only getting 4.6kW of usable power. Compare that with an inverter that has 97% efficiency—you’d be getting 4.85kW. Over a year, that difference becomes hundreds of kilowatt-hours. So yes, inverter efficiency really matters.
It is important to note that the inverter efficiency declines with a small rate after peaking with incident energy levels around 400–700 W/m 2 due to the temperature increase inside the inverter when it handles loads with more power .
Inverters achieve peak efficiency at 70–90% load. When oversized, they operate at low loads (e.g., 10–30%), wasting energy through higher standby consumption (up to 50W daily) and reduced conversion efficiency. Upfront Expense: Larger inverters cost 20–50% more than appropriately sized models.
In general, the efficiency of a PV inverter is a function of the input power and input voltage, with a typical set of efficiency curves being shown in Fig. 1.4. At medium to high light levels and therefore input power from the array, the inverter has a high efficiency, generally well in excess of 90%.
