Ups won't stop beeping when on Tesla powerwall (power outage)

First off I'm sorry if this is the wrong Reddit but anyone knows why my 2 UPS won't stayon/stop beeping when im on my powerwall even though everything else has power that isn't connected to the UPS side...

In a active power outage....

Sidenote - I got the powerwall before elon drank the Kool-Aid...

Thank you.

Update - It looks to be something do with the frequency. All my UPS turned on after almost an hour off... might want to call your provider if you are experiencing the same thing as me.
