I sort of wonder how my panel is setup. Has a warning there is a secondary
AC source. I have rooftop solar panels. The panel is designed to work
with solar panels. Maybe you just have to,turn off the circuit breakers
for the panels.

If you have a grid tie system the panels go to a back feed breaker on
the bus, usually at the bottom. There is no power from the collectors
if the grid fails but I think a small generator or even a good sized
inverter would tickle the inverter and bring them back to life. You
would still need a panel interlock for your generator/inverter.
