These larger motors and multiple batteries are wired in a series pattern and optimally the circuit breaker should be wired within 4 of your battery. If that is not an option know the advantages and disadvantages of both systems to help you choose between them.

24 volt battery configuration. Myself for safety i would run the 4 as 2 banks to a switch in a 24 volt setup. For most off grid pv systems the battery bank is configured as 12 volts or 24 volts. Loose or dirty connection and a heavy draw will melt fry off the battery post. The only drawback i can think of and it is probably because i was a mechanic in the service working with 24 volt setups. Saru if i have a 36 volt 20 ah battery that has a 1 c rate and i use a 12 volt step down convertor to make it 12 volt battery am i okay using trolling motor with a max 60 amp draw. Just connect the 12 volt winch to one 12 volt battery.
1700 wh per day 1085 inverter eff 2 days of storage 1050 max discharge 124 volts 333 ah at 24 volt battery bank. Therefore it is an added advantage to have both power systems working for you at the same time. Is you only have 1 ground and 1 hot with the power of 4 batteries. 333 ah 28 volts charging 1077 rate of charge 010 rate of charge 1211 watt array nominal. Obviously connect the input to both batteries and connect the 12 volt output to the 12 volt winch. 24v systems require two 12v batteries in series which increases the weight and volume of the battery bank.
And then there is sizing the solar array based on where you live. Your rv will have either a 6 volt battery configuration which is connected in series positive to negative to create a 12 volt bank or a 12 volt battery connected parallel positive to positive negative to negative to also create a 12 volt bank with twice the amp hours. Plus the advantage of using smaller wire is only realized when the currents are large or the wire runs are long. Batteries used for such systems are usually made up of either. Buy a 24 volt input to 12 volt output transformer. While small and medium trolling motors use a single 12v marine battery larger trolling motors use larger 24v and 36v systems and require 2 or 3 marine batteries accordingly.
Battery possible configurations for using 6 8 12 volt batteries please click on any configuration to learn more about its specification and possible applications. Also 12v systems require a single automotive style battery to make them operate. More sun you can use a smaller array. 6 volt lead acid batteries common in electric golf cart applications 12 volt lead acid batteries such as deep cyclemarine batteries. Check your cigarette lighter voltage. Most appliances especially those used domestically operate either on a 12 volt or a 24 volt power system.
