When installing my system I used 4/0 welding cable with equal runs connecting 4 batteries ( 450 ah ) and a 2,000 watt Magnum inverter. Fuse the + at battery. All terminals are both crimped and soldered. Estimate your needed run and buy the cable in one piece and cut to desired lengths. Simple and minimizes loss.
4/0? OMG, why?
Presume you had it laying around and then thus more economical than buying adequate but much smaller cable?
Mine is wired the same way, and nope, didn't have 4/0 just lying around. Depending on the draw (microwave, etc), you can pull several hundred amps off the batteries in short bursts - I've seen in excess of 300. Much smaller wire will not be up to the task.
