Hi all. I just got my IoTaWatt device, and am looking forward to joining the community!
I have a question…
Here is the scenario: I have two 100A CTs on the mains for a sub-panel that I have. This sub-panel aggregates multiple solar circuits (energy production), but I also have a circuit on that sub-panel which draws energy (energy consumption). Specifically that consumption circuit is a double pole circuit dedicated to EV charging. I usually charge at night after solar production stops, but in emergencies I also charge in the day.
Should I “Allow negative power value” when configuring the two CT inputs for the solar sub-panel mains?
