24V battery bank with solar - pros and cons
Hmmm.... should I go with a 24V Battery bank? I am in the planning phase of a 800 to 1,000 Watt solar system for my 5th wheel. I am thinking maybe a Morningstar TS-MPPT-60 charge controller and 4 ...

Pros of 24V vs. 12V battery bank:
- Solar controller (TS-MPPT-60) can double the power (Watts) it can output when charging a 24V battery bank vs. 12V (60Amps X 24V vs. 60Amps X 12V)
- Battery wires can be thinner due to lower current flow
- Batteries will perform more efficiently due to lower current flow
- inverter will be more efficient from 24V DC (not sure about this one)
using the 60 amp controller your looking 700+ watts for 12v system
or
1400w max for 24v system
so your 1000w system will be less than 60 amps about 36amps at 28.x charge
so you can use smaller wire to the batteries
60amps is 60amps
the wire has too be the same size
the difference is the number of WATTS you get for the amps
1000watts at 12v nominal will need larger wire than 1000w at 24v nominal ( 1/2 the amps )
but if your counting max amps.. same size wire
