High String Input Voltage

Hva betyr 2001 ?

The open-circuit voltage of the PV array exceeds the maximum input voltage limit of the SUN2000 due to an excessive number of PV modules connected in series. This indicates a potential overvoltage condition for the inverter's DC input.

• Excessive PV modules are connected in series in the PV array. Therefore, the open-circuit voltage exceeds the maximum input voltage of the SUN2000.

1. 1

   Check the number of PV modules connected in series in the PV string.

2. 2

   Ensure that the PV string open-circuit voltage is no greater than the maximum operating voltage of the SUN2000.
