Do you have to notify the utility?
No. Section 9 has no notification step. No electric distribution company may require approval before installation or use, any fee, or additional controls, and the device is exempt from PURA interconnection-agreement requirements.
What is the catch with excess generation?
Section 9 requires a consumer warning: any excess electricity the device sends back is charged as usage unless the customer uses a net-metering-capable meter.
How Connecticut differs
Connecticut names UL Standard 1741 rather than UL 3700, and it is one of the few laws that flags the metering point: excess output is billed as usage unless you have a net-metering-capable meter.
