A cabin sits on a mountain top in North Carolina. The location
has a latitude of 35 degrees North and 4.8 hours of insolation. The
daily load requirement is 3 kWh. The designer has installed a 48
Vdc stand-alone system that has been derated at 75%. The inverter
is 95% efficient. The temperature extremes at this location are -37
degrees Celsius (coldest) and 43 degrees Celsius (hottest). The
battery bank provides two days of autonomy and uses 6-volt,
250 Ah batteries to a 60% depth of discharge. How many batteries
did the designer anticipate would be required? Pick one answer and
explain why.
A) 1
B) 3
C) 8
D) 24
