What does the 'Alarm: OC' error message mean and how do I fix it?
The 'Alarm: OC' Over Current fault occurs when the current exceeds 15% of the rated current (exceeds 34.5A for the 30A controller). This is an overvoltage/overcurrent protection event. Check that your solar array current does not exceed the 30A rating and ensure proper wiring connections. (Page 37)
