Most likely bad connection between your panels. Or you own connections.
First check for polarity preferably whit an decent multimeter.
Then check if you can draw an ark or just some little sparks ( be careful if your inexperienced) if noting then there is an break in the circuit, only sparks is high resistance connection., if full ark it should be fine.
