Today was a clear day and I made just under 90 kWh according to the stats from my microinverter gateways. However, Sense showed only 77 kWh. The reason for this, I think, is that for the period between noon and 1pm, the 2nd Solar CT was either not reporting at all, or reporting way lower that the other one.
Here’s my power meter for today:
And here’s the report from my gateways:
Power curves from both arrays are nice and smooth around lunch time.
And here are some snapshots I took of from the Sense Status screen during the noon to 1pm window:
And here’s one from a little after 1pm when everything was back to normal:
And here’s a shot from after dark showing just the always on loads in the subpanel my inverters are connected to:
So what gives? A bad solar CT, or some issue with the Sense unit itself?
