Common Faults and Troubleshooting
The PV string cables are
connected reversely
during the SUN2000
installation.
Wait until the solar irradiance declines at night and the
PV string current reduces to below 0.5 A. Then, turn off
the two DC switches, remove the positive and negative
connectors, and correct the polarity of the DC input
power cable.
