intersection of the time and temperature will indicate approximately the
output power of the unit. For example, between – 40 °F (– 40 °C) and
77 °F (25 °C), you will get 3000 watts for approximately two minutes or
2500 watts for 3 minutes.

Calculating size of an AC load
Operating time
To determine how long you can run your appliances:
1. List all the AC loads you think you will use and determine their
power requirement. You can usually find this information on a label
near the power cord on the appliance.
2. Look in
to find its operating time or the operating time of a
similarly sized appliance. The operating times shown in the table are
the maximum time the appliance will operate. The unit will shut
down after that time so the battery is not drained past a safe level.
3. To find the running time for several appliances running
simultaneously add the total watts of the appliances and look for an
appliance with similar power requirement in
.
