To fix a fault and stop the red alarm light on the Sofar ME3000SP, follow these steps:

1. Check Event List: A red light indicates there are events in the current event list. Review the event list on the ME3000SP to identify the issue.

2. Double Check Connections:
- Ensure the ME3000SP is firmly mounted.
- Confirm battery wire polarity is correct and connections are secure.
- Verify the DC isolator (between battery and ME3000SP) is connected and turned OFF during checks.
- Ensure GRID and LOAD cables are correctly and firmly connected.
- Check that the AC circuit breaker between GRID port and GRID is correctly connected and turned OFF.
- Confirm the AC contactor is correctly connected (if used).
- For lithium batteries, check the communication cable is connected.
- For lead-acid batteries, ensure the NTC wire is connected.

3. Resolve the Issue: Based on the event list and checks, correct any identified faults.

4. Clear Events: After fixing the issue, the red light should turn off. If not, clear the events manually if the system allows.

If the red light remains after all checks and corrections, contact technical support.
