Jackery 5000 + - what's that tiny green blinking LED inside the inverter?

Newbie Jackery 5000+ question -

When the house is dark I can see a small green LED blinking deep inside the inverter. Didn't notice it the first couple weeks.

Has anyone else noticed the same? The unit seems to be working fine. I'd just like to know for my own peace of mind what that LED means. Hopefully it means "Your Unit is Working Perfectly".

It part of the BIT. Built in Test system. It allows them to test the boards quickly during assembly and repair.

OK, thanks, good to know...

I think it’s the “dont look at this” light. :D
