Why SOL detected this
- Peak internal temperature 68.4 °C against a peer median of 53.9 °C.
- Output drops by 4% to 6% during the hottest hour while peers hold output.
- The gap grows on clear days.
Most likely cause
Restricted cooling, most likely a blocked air path or a degraded cooling fan.
Other possible causes
- Blocked ventilation grille or filter
- Failing cooling fan
- Direct sun exposure on the enclosure
- Ambient conditions at the mounting position
Recommended inspection
These steps become the technician checklist
- 1Inspect and clean ventilation paths and filters
- 2Test the cooling fan operation
- 3Check for direct sun exposure and consider shading the enclosure
