You have to use a larger gage wire to that distance.
I would suggest to find a way to install the Inverter close to the source.


But not too close if you're running wet cell lead acid batteries; the
fumes during charging are corrosive to electronics. And not in the
engine compartment, as it gets hot (and sometimes wet) in there. That
5' length of wire supplied by the manufacturer sounds about right.

If you're regularly running 200 amps to the inverter you've got at
least 500ah of battery capacity, right?
