Power factor resolution algorithm


This document describes the methodology we followed to compute the power factor at the inverter output used by RatedPower's pvDesign.

The goal is to calculate the required cosine of phi value at the output of the inverters to meet some given grid requirements, such as a specific power factor value at the delivery point.

We'll focus on the criteria we use to design the algorithm and explain you what decisions we made and why.

If you're evaluating if RatedPower's pvDesign is the right fit for your business, this document will provide you with a solid technical knowledge for engineering assessment.
