Temp Fault
Temperature Fault
Inverter or battery temperature is outside the permitted operating range.
Common causes
Ambient temperature too high (inverter: >60°C, battery: >45°C)Poor ventilationDirect sunlight on unitHeat source nearbyBlocked ventilation slots
What to check
STEP 1
Check ambient temperature at the installation location. Ensure ventilation clearances are met (min 300 mm above and sides)
STEP 2
If in direct sunlight, provide shading. Check inverter/battery heat sink for dust blockage
Escalate if
Temperature fault occurs at normal ambient temperatures — possible cooling system failure, escalate
