Environment:
12V or 24V DC battery systems
Cause:
F10 indicates a high battery voltage condition:
Above 15.5 V on a 12 V system
Above 31 V on a 24 V system
This typically occurs when the batteries are wired incorrectly, or an external charging source is pushing the voltage too high.
Resolution
Verify the batteries are connected in the correct configuration for the system (12V or 24V).
Check for external chargers, alternators, or solar controllers causing over‑voltage.
