The system should look more like this;

System voltage 24 Volts
Battery Volts 2V
Daily load 15kWh
2 days autonomy
Battery bank capacity 2000 Ah
Daily Depth of Discharge %
Array output required /day
PV module output 6A
Guaranteed current
Number of modules in series 2
Number of parallel strings


I have made some assumptions.

One is using an average of 6 amps output across the 75 W and 100W
panels and have probably erred on the high side.

The only way this system can get even close to doing what is claimed
by the owner is to run all the loads possible during daylight hours.

Of course if he had started with a proper energy audit and designed to
correct parameters the system would have looked more like this;

System voltage 48 Volts
Battery Volts 2V
Daily load 15kWh
2 days autonomy
Battery bank capacity 1000Ah
Daily Depth of Discharge %
Array output required /day
PV module output 6A
Guaranteed current
Number of modules in series 4
Number of parallel strings 16

Overall, the claims made by Wayne are, at best, pure fiction.
