I have a PV + hybrid inverter + battery backup system + critical loads panel. The CTs are installed on the mains and on the output of my PV system on it’s way to the inverter. (Yes, I have contacted sense support about this behavior)
When I’m running in “normal” mode, everything looks great in Sense. Things go a little sideways, however, if I program my inverter to power the critical loads from the battery when there’s no PV. When running in this mode, the Other bubble on the now page disappears and re-appears every second. The Solar tab shows power coming from the grid, then falling to zero, then coming from the grid, at the same rate the other bubble appears. On the power meter page, I see a weird sawtooth signal for the usage.
I’ve attached a screenshot of what the power meter shows. In this sample, battery discharge started at 5:00 am, and you can see the weird sawtooth signal when it starts. If you were to average out that sawtooth, it would be pretty close to my always on non-critical load usage (200-300w).
I’m curious if this just how it works when you have a hybrid inverter supplying power, or if there’s some setting or CT placement that might improve it. Sense is still doing what I need it to do, which is to tell me when I’m buying power from the utility, so getting this ironed out would be gravy.
