Time versus Current
Loads presented to the inverter are seldom constant. Typically, large loads
are operated for only short periods of time. In order to provide the
maximum utility, Xantrex inverters are allowed to operate at power levels
that exceed their continuous power ratings. This graph shows how loads
that are larger than the inverter can sustain continuously can be operated
for useful periods of time.
The length of time that the inverter can operate at high power is limited by
temperature. When large loads are run, the inverter’s temperature
increases. At the point where more heat is created in the inverter than can
be dissipated, its ability to operate becomes time limited.
