Solar customers: Recognizing the "Daytime dip" and how it might impact your Sense numbers

[NJHaley]

@Stuart

But if the Sense monitor is reading the solar production 2.5% low, it will be registering 9.75kW solar production, 9.75kW going to PG&E, and therefore zero consumption in the home.

I think the Sense monitor algorithms will have trouble reliably detecting loads if it’s reading zero when actually 250W is being used.

Thinking further, to 11kW production and 200W always-on, the error in the sense reading will be greater than the entire load it’s trying to measure. That can’t be good.

Ding ding ding! In fact, your always on turns to zero, which is something I started noticing as our days started getting longer and less cloudy:

Prior to a couple weeks ago, we were pretty cloudy since right around Xmas (when I started up my replacement Sense device), not making too much more than we were using. Back then I posted a thread winning “always on” value: So what is your MINIMUM power usage? 249 here for a big house - #2 by NJHaley Now I’m at zero

I think this horse has been beaten - now to hope Sense makes strides to fix it.
