Update
Removed the inverter and found that the battery cables were fine. The ground wire was not grounding to chassis and it appears the burning was the bare ground wire melting the flex casing around the positive terminal. Fixed the ground issue and connected it back to a battery and it still gives the Overload fault.
Would a poor ground cause this? I think the inverter is toast. Just trying to figure out the cause. Haven’t opened the inverter to see what’s inside.
