Questions and answers

@William Walker
@Alan Mainwaring
Error code 1 indicates that the fan is locked, and error code 2 indicates over-temperature. Since both units appear to function normally, you should still address these issues to prevent potential problems:
1. For Error Code 1 (Fan Locked):
- Check the fan for any physical obstructions or debris.
- Ensure the fan is properly connected and functioning.
- If needed, replace the fan.
2. For Error Code 2 (Over-Temperature):
- Verify that the unit is in a well-ventilated area.
- Check for dust accumulation or blockages in the cooling system and clean them.
- Ensure the ambient temperature around the unit is within the specified operating range.
Both issues should be addressed promptly to maintain optimal performance and avoid further damage.

What are the contribution factors that could have might be the root problem of the SPF 5000 Growatt inverter causing the beep signal to display the code 02?
Anderson, I **** quite satisfied with your advices. I'll check through before I can give your any further updates, thanks!
The beep signal displaying code 02 on the Growatt SPF 5000 ES inverter indicates an over-temperature fault. This issue can be caused by:
1. Poor ventilation – The inverter may be overheating due to insufficient airflow.
2. High ambient temperature – Operating in a hot environment can lead to overheating.
3. Heavy load – Running the inverter at high power for extended periods may cause excessive heat buildup.
4. Faulty cooling system – A malfunctioning or blocked cooling fan can prevent proper heat dissipation.
To resolve this issue, ensure the inverter is in a well-ventilated area, check for dust or obstructions in the cooling system, and reduce the load if necessary.
