Huawei SUN2000-3KTL-M1 User Manual

WARNING
Ensure that the following conditions are met. Otherwise, the SUN2000 may be
damaged, or even re could happen.
● PV modules connected in series in each PV string are of the same specications.
● The open-circuit voltage of each PV string must always be 1100 V DC or lower.
● The maximum short-circuit current of each PV string must always be 15 A or
lower.
● The polarities of electric connections are correct on the DC input side. The
positive and negative terminals of a PV string connect to corresponding positive
and negative DC input terminals of the SUN2000.
● If polarity of the DC input power cable is reversed, do not turn
o the DC
switch immediately or remove positive and negative connectors. Wait until the
solar irradiance declines at night and the PV string current reduces to below 0.5
A, and then turn
o the DC switch and remove the positive and negative
connectors. Correct the PV string polarity before reconnecting the PV string to
the SUN2000.
NO TICE
● Since the output of the PV string connected to the SUN2000 cannot be
grounded, ensure that the PV module output is well insulated to ground.
● During the installation of PV strings and the SUN2000, the positive or negative
terminals of PV strings may be short-circuited to ground if the power cable is
not properly installed or routed. In this case, an AC or DC short circuit may
occur and damage the SUN2000. The caused device damage is not covered
under any warranty.
