Connect to PV Panel (DC input)
1. Make sure the maximum open circuit voltage
(
V
oc
) of each PV string is less than 500V
DC
(or
450V
DC
for CPS SC1.5KTL) UNDER ANY
CONDITION. We recommend use the solar
modules, whose total U
MPP
at STC in the string
between 250
V
DC
and 350
V
DC
(200
V
DC
and
320
V
DC
for CPS SC1.5KTL) with ambient
temperature 25
°
C.
2. Use MC-4 connectors for PV array terminals.
3. Connect the positive and negative terminals from the PV panel to
positive (+) terminals and negative (-) terminals on the PV-Inverter.
