Harold:
The 'tap' being ahead of the main OCP will have power unless there is a POCO interuption. That goes for the panel, and the utility side of the inverter.
Most, if not all of the inverters will shut OFF when the circuitry senses 'no power' from the POCO grid tie, like a power failure, or pulling the meter IF the line tap is ahead of the main OCP.
You can achieve the inverter shut down by opening the POCO required disconnect (AC).
