The only reason I can think of would be voltage drop during startup inrush current. Remember, all wire and connections are resistors, with very small values. If the inverter takes a large amount of current to start, the voltage drop in a smaller wire may drag the voltage on the inverter input connections below a critical value, possibly causing it to oscillate on and off during startup. I am not familiar with this particular inverter so canít say for sure. A quick call or email to the manufacturer may be able to answer the question.
I feel for you, many a time Iíve scraped my knuckles on large cable crimps. 4/0 does seem a little excessive.
