Planning for AC Loads

2–5
3. To find the running time for several loads running simultaneously,
add their total wattage and look for an appliance with similar power
requirement in Table 2-1.
Battery
condition
The information in Table 2-1 assumes:
•
there is a properly maintained 12 volt 400 amp-hour battery bank, for
example, 4 Group 31 (100Ah) deep-cycle truck batteries or 2 Group
4D batteries
•
the batteries have not been damaged by deep discharge and are
relatively new
Factors
affecting load
Consider these factors when you are calculating loads:
•
Loads that exceed 1000 watts may be run for a short time (about one
minute).
•
Loads which run continuously such as a reading light, TV or
computer should not exceed more than 1000 watts in total.
•
Poor battery condition, low battery capacity, low battery temperature,
and high ambient temperature will shorten the operating times listed
in the table.
•
The presence of DC loads will reduce the operating times of the AC
loads.
