There is already a single LED in most utility meters that tells you the
grid is on. I have marked it with a sharpie for a client.
I suppose you want something for clipping on to the Grid input that can
give an alarm in the house.
Amazon had something that I used once. Will try and look it up.

Dear Esteemed Wrenches,
This issue arises periodically, and I'm hopeful someone in the group
has devised a cost-effective, low-power solution.
For a whole-home backup system, how can we best alert homeowners that
they are operating on battery power? These homeowners do not use
smartphones and won't receive push notifications. Is there a simple
solution to activate a single light or audible alarm exclusively when
the grid is down? This particular instance involves a FranklinWH
system, but the same challenge applies to any battery with a whole-home
backup and "instant-on" transfer switch.
Thank you in advance for your insights.
Sincerely,
Nicholas Ponzio
