Understanding inverter efficiency curves

The efficiency of an inverter is usually expressed in terms of a curve. However, it can be difficult to interpret efficiency curves to make informed decisions about your installation.
The traits of a good efficiency curve
Above all else, a good efficiency curve should reflect consistent performance in a wide range of conditions and light levels.
Generally, efficient inverters:
● Create curves that rise quickly, denoting good low light performance
● Create flat curves with no obvious dropping phenomenon
● Offer high performance under full load (at the right end of the curve)
● Show overlapping curves at different voltages
In practice, a weighted efficiency rating can be a more reliable overview of performance. They measure performance across the full capacity of your inverter.
