Likely increase in performance of your inverter compared to an inverter with the least favourable choices for all the parameters. Performance is an indicator of both qualitative aspects such as reliability and quantitative aspects such as generation.
The benchmark generation is the generation of the solar inverter with the least favourable choices for all the parameters.
The benchmark cost is the cost of the solar inverter with the least favourable choices for all the parameters.

Brains of the solar plant
The Inverter in a solar plant converts the electricity produced by the panels (which is in DC form) to AC so that you can use it just as you use the grid power. The following are the key parameters you should use to select the right inverter.
