1. An inverter comprising:
- a main circuit part that converts DC power to AC power;
a communication part that communicates with an external apparatus through a network; and
a control circuit part that controls conversion by said main circuit part and transmits condition data representing current conditions related to said inverter to said external apparatus through said communication part;
wherein said control circuit part includes;
a measuring part that measures an operating time of a system associated with said inverter based on a detection output from an external sensor;
a memory that stores a threshold value related to said operating time; and
a comparing part that compares a measured operating time measured by said measuring part with said threshold value, said condition data including a result of comparison by said comparing part.

Abstract
An inverter has a measuring part that measures an operating time such as the time interval from when a command to start a specified operation by an associated system until a signal indicating the completion of the operation is received. A comparing part compares this measured operating time with a threshold value stored in a memory and an abnormal condition is reported to a host system, depending on the result of the comparison.
