Power converter failure detection and prevention

A power device comprising:

• a housing comprising a cover;
• a printed circuit board (PCB), wherein the PCB is located inside the housing;
• at least one electrical component comprising at least one attribute, wherein the at least one electrical component is located on the PCB inside the housing;
• at least one sensor configured to monitor the at least one attribute, wherein the at least one sensor is located on the PCB inside the housing, wherein the at least one attribute is generated inside the housing;
• a non-transitory computer-readable storage medium comprising at least one alerting rule;
• at least one processor configured for:
• retrieving the at least one alerting rule from the storage medium,
• monitoring at least one sensor value from the at least one sensor, wherein the at least one sensor value is associated with the at least one attribute,
• evaluating the at least one alerting rule during the monitoring, and
• when the at least one alerting rule results in a pending failure condition, sending a notification to a user;
• wherein the cover comprises at least one of a waveguide and a reflector, and wherein the waveguide or the reflector are configured to direct the at least one attribute from the at least one electrical component to the at least one sensor.
