Hey guys, im trying to solve this problem. I'm a student and new to this topic.
I think that 1 might be the faulty one, because killowatt cant be below zero? but i'm not sure.
I'd appreciate your guidance/help. Thanks in advance!

I agree with your reasoning. The weather can behave in strange ways and produce strange output curves, but an inverter should not be absorbing power.
