DC Input Over Voltage Warning — The DC Input Voltage (PV) is too high

What does DC Input Over Voltage Warning mean?

The DC input voltage from the PV panels is higher than recommended but not yet critically high. This is a warning that may lead to a fault if conditions persist.

• The DC Input Voltage (PV) is too high.
• PV panels are experiencing extreme cold temperatures.
• The installation may have too many PV panels in series.

Click steps to track your progress.

1. 1

   Monitor the situation; the warning may clear as PV panels warm up and voltage decreases.

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 warning occurs regularly, consider reconfiguring the PV array.
