Calculating Size of an AC Load

Operation

Figure 2-1 shows the relationship between ambient temperatures and the length of time the unit will supply an output power level. Choose the curve with the temperature range most closely approximating that of the inverter/charger location, then look for the time in minutes. The intersection of the time and temperature will indicate approximately the output power of the unit. For example, between – 40 °F and 77 °F (-40 °C to 25 °C), you will get 3000 watts for approximately one minute or 2500 watts for 3 minutes. Times shown in this graph may vary with the actual operating conditions.

Operating time

To determine how long you can run your loads:

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 Table 2-1 on page 2–6 to find the load’s operating time or the operating time of a similarly sized appliance. The operating times shown in the table indicate approximately how long a load will run before the inverter/charger shuts down to prevent battery damage.
