If it where me, not that it is.  I would expect to see some numbers even in a short presentation.  Hopefully the engineers have chosen to be there so they are more likely to not switch off.

Are there any harmonic issues with the sensing as these can be generated from switch mode power supplies that are turning up more and more?

Frequency can also drop due to poor power factor not that its such an issue for domestic loads.

I am glad someone is bringing up this idea to more people who might do something about it.

Have you considered getting any work published in say ReNew?

Carry on the good work, still green eyed with you PV array.
