LG TV blinking 2 times while on standby (UPS battery)

Why does my LG C1 blink twice sometimes when under the UPS battery power. This does not happen immediately but after like 5-10 min. Sometimes the red light also turns off after a while after blinking. TV runs fine later though, I just need to know why is this happening.

There are no other loads on the ups except my ps5 but that is turned off in 20s. I have to wait at least 10 min before turning the ups off because of pixel cleaning.

This ups is a 1500VA/900W outputting simulated sine wave and has no problems supplying power as I have tried it on other appliances and my PC.

They do maintenance while they're in standby, like pixel refresh.
That second blink just indicates the maintenance session is complete.
