String Reversed

What does 2011 mean?

The polarity of a PV string connected to the SUN2000 is reversed. This can cause the inverter to stop generating power and potentially damage internal components if not corrected.

• The PV string is reversely connected.

Click steps to track your progress.

1. 1

   Check whether the PV string is reversely connected to the SUN2000.

2. 2

   Wait until the solar irradiance declines at night and the PV string current drops to below 0.5 A.

3. 3

   Set the DC SWITCH to the OFF position.

4. 4

   Correct the string polarity.
