Measuring voltage



If the voltage is a negative value, the PV string is of reversed polarity. Correct before
connecting this string to the SUN2000.



If the voltage is greater than 1100 V, too many PV modules are configured to the same
string. Remove some PV modules.

Step 3

Pull out the blue dustproof plugs from the ends of the DC input connectors.

Before performing

Step 4

, ensure that the two DC switches are OFF.

Step 4

Insert the positive and negative connectors into the corresponding positive and negative DC
input terminals of the SUN2000 until they snap into place.

After the positive and negative connectors snap into place, pull test to the DC input power
cable is recommended.
