DC Over-voltage shutdown

DC Over-voltage shutdown — Input voltage is too high

Schneider Electric · MPPT 80

What does DC Over-voltage shutdown mean?

The DC input voltage is too high, causing the system to shut down. This can occur if the DC input voltage exceeds the operating specifications.

Common Causes

  • DC input voltage is too high.
  • PV panels are producing voltage levels outside operating specifications, possibly due to extreme cold temperatures.
  • Too many PV panels in series may need reconfiguration.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Check if the condition is due to extreme cold temperatures; it may correct itself as panels warm up.

  2. 2

    Verify the number of PV panels in series is within the charge controller's operating range.

  3. 3

    Consult the 'Electrical Specifications' for the charge controller's operating voltage range.

  4. 4

    If the issue persists, contact a qualified installer for potential reconfiguration.
