Your alternator will not be delivering 200 amps for very long, if ever.
When charging current is "high" the closer bank will accept charge
faster than the farther bank. Eventually, as the charging current
diminishes, the voltage drop across the 4/0 cable will fall further into
insignificance.

Apply Ohm's law and work out the numbers.

I agree with you. For adequate parallel installation, make sure the
cables from each pair to the strips are identical, also re total
length (total length of both + and - cable should be identical). That
way you prevent different charging and draining of each 12-v set


Which brings up another quandary. The voltage drop across 5' of 4/0 will be
small but my house alternator is capable of delivering over 200 amps and the
inverter can draw pretty close to the same thing. Electrically the ideal
place to tap in the alternator and house loads is under the sole in the
middle of the companionway but I am a wee bit worried about having those
high power connections down in the bilge.
