ADE 7878A and high frequency VFD measurement

Hello, I am planning to use ADE7878A IC for measuring 3 phase power for our VFD operated motor. The input voltage is about 230 VAC RMS and current about 20 A. (using CTs as transducers) and I plan to take the measurements after the VFD which has 230 Hz base frequency. Now my question is, despite having a 2 kHz bandwidth for measurement, what kind of deviations, or errors are possible when it comes to calculating power consumption and other similar values? Is there any other solution or appropriate IC for such situations?

Thank you!
