What to do if my DAYLIFF SUNVERTER B Controller displays OC1 (Overcurrent when Accelerating)?
- SswilliamsAug 20, 2025
If your DAYLIFF Controller displays OC1, it indicates an overcurrent during acceleration. This could be due to several reasons: the acceleration or deceleration being too fast, low input voltage, the inverter's rated power being too low, an abnormal pump load, or abnormal cables. To resolve this: 1. Increase the acceleration or deceleration time. 2. Check the input power supply. 3. Choose an inverter with matching power. 4. Check for a locked-rotor pump motor, unbalanced three-phase resistance in the pump motor, or uninsulated motor phase cables. 5. Check the output cables for correct connection and proper insulation.
