Off grid solar invertor won't turn on when sun is up

[MarkPluto]

Good day

I installed a new 5kw system with a lithuim battery
Invertor: Growatt spf 5000 ES

The problem is the battery is small and con't hold up all night so the system turn off when the battery is empty but in the morning it won't start when the sun is up and I have to jump start the system using utility.

I have other 3k system and they work fine in the morning they auto start fine.
if anyone could help and thanks in advance.

Do you have rapid shutdown? May need to power that circuit.

Are you getting 160v (voc)from your panels? I believe that's the required voltage to start producing
