(DOD). In Extreme Emergencies, the Auxiliary DC Output can be
utilized for 100% DOD, although this is not recommended as it
would substantially shorten the life of the batteries.
FORMULAS:
a. TAKE CONSUMPTION OF WATTS / 120 = AMP AC
b. AMP AC x 12 = AMP DC
c. Battery Capacity / AMP DC = Run Time
EXAMPLE:
100 Watts Appliance / 120 = 0.83 AMP AC
0.83 AMP AC x 12 = 10 AMP DC
70 Ah / 10 = 7 hours run time
