The "X" stands for the affected string. This
string polarity is either reversed or the
string has failed. Further strings may also
be affected. The PV array is not short

• Disconnect the inverter
(see Section 9 "Disconnecting the
Inverter from Voltage Sources",
page 63).
• Check the design and the circuitry of
the PV array (see Section 6.4.1
