Small AC motors and Inverters
Disappointed that my ancient Mod Sine Wave inverter (140W cont, 200W surge) shuts down with a 120W coffee grinder. Works ok with the 400W (cont) MSW inverter built-into the truck, though a little ...

Don't be afraid to double up the wires, just keep them all the same lengths.
Pray tell why should the lengths of necessity be the same?
For interconnections between paralleled batteries, I can see where having equal length wires would help promote balance (or at least not promote imbalance), but once you get beyond that, it seems to me you'd just want as short of total length as practical. It's not like the electrons that go from the negative pole of the battery to the inverter need to have the same resistance as those that return from the inverter to the positive pole.
Edit: or do you mean paralleled conductors on the same leg should be of equal length? I guess that makes more sense and would tend to prevent current hogging by one (shorter) one, though I don't think even that would be a huge problem if the wires are adequately sized for safety—which I think typically would be easily the case if you're sizing to minimize voltage drop.
