At an approximate altitude of 3000m and 40°C ambient temperature, the power output coefficient is 0.58.
So, a rated output of 2.0kW becomes 2.0 x 0.58, which equates to an actual power output of 1.16kW.
Calculating Generator Load
Most electrical devices clearly state the required power, usually in Watts (W). This information is generally
labelled on the device, or listed in its user manual. If a device lists power consumption figures in amperes
(A) only, calculate the wattage by multiplying the ampere rating by the voltage. For example, a 10A device @
240VAC equates to 2400W (10A x 240V). The sum of all devices required to be operating simultaneously
needs to equal or be less than the rated output of the generator.
Many devices require a different load on start-up/shut-down that is often much higher than the actual
continuous running requirements. For example, a water pump may require 2000W to start, and once started,
requires 500W to continue running. When calculating generator load, the start-up requirements need to be
factored in. If the start-up power consumption is not known, the table below lists typical consumption figures
for several device types that may assist in determining how many or which devices may be connected and a
starting order [that is, start the high consumption devices first, followed by devices with no additional start-up
power requirements].

Example (using the typical values above):
•
To run a radio, electric fan and small refrigerator requires an approximate running power consumption of
100W (radio) + 200W (fan) + 600W (refrigerator) = 0.9kW. However, when factoring in start-up power
requirements, the equation becomes 100W (radio) + 600W (fan) + 1500W (refrigerator) = 2.2kW.
