Suggested cable width for AC wire
Model
CPS SC1.5KTL /
CPS SC2KTL
CPS SC2.8KTL
CPS SC4KTL /
CPS SC4KTL-O
Connect to PV Panel (DC input)
1.
Make sure the maximum open circuit voltage
(V
) of each PV string is less than 500V
oc
450V
for CPS SC1.5KTL) UNDER ANY
DC
CONDITION. We recommend use the solar
modules, whose total U
between 250V
320V
for CPS SC1.5KTL) with ambient
DC
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.
