XW Inverter/Charger Overload Capability
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.
