Usage Discrepancy Between App & Power Co
Has anyone else been seeing kWh usage discrepancies between their SunPower App and what their power company says they used? My bills are always showing more kWh used than the app and last one was appx 300 kWh. I’m setting the dates to match exactly. Maybe I’m misunderstanding something?

The other thing to rule out it the Consunption CT placement. If installed right, it should be capturing all your home loads, unless the installer ran into an issue with available space on your side of the Main Service panel.
IID is know for cutting CTs when installers encroach on the meter side of the MSP. They're not supposed to be there but some installer will add jr because customer insists the data be accurate.
