New Growatt 3000TL LVM-24P: 7-8 hours after power on, there are many lines and numbers missing in the screen display.

New Growatt 3000TL LVM-24P, was just used several days. I found that about 7-8 hours after power on, there are many lines and numbers missing in the screen display. I waited for a few days and the situation did not get better( see pictures). Is there something wrong with it? Where should I contact for help? Thanks.

That doesn't look right, I would contact Ian @ Watts24/7, you may have a bad unit.
He's a nice guy and has answered all my dumb questions so far.
