DC Over-voltage shutdown — Input voltage is too high

Was bedeutet DC Over-voltage shutdown ?

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.

• 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.

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.
