Inverter Specifications

Inverter Capacity versus Temperature
The output power of the inverter diminishes as ambient temperature rises.
However, as can be seen below, with the exception of the SWP5548, these
inverters are sized to be able to run a full rated output power up to 40C.
However, it should be noted that the overcurrent circuit on the unit is
temperature compensated to protect the unit and that the thermal circuit
breaker will trip at a lower current as the temperature rises. Therefore, the
surge ability of the unit decreases with increased temperature.
This table refers to output VA only. Testing was conducted in a thermal
chamber with the inverters as stand-alone units without accessories.
