5.3 DC Connection (from PV Array)
WARNING
When doing DC wiring, please choose the proper wiring by
connect to the correct polarity.
When doing DC wiring, please confir
m that PV Array’s power
switch is off.
CAUTION
The connection number of PV Array, open circuit voltage and
power of String_1 and String _2 must be coherent.
The connection number of PV Array, open circuit voltage and
power of String _3 and String _4 must be coherent.
The maximum open circuit voltage of PV Array can not be higher
then 1000V.
The range of Vmpp of Input1 and Input2 shall be in 350~800 Vdc.
The device installed between PV Array and inverter must meet the
rating of voltage >1000 Vdc and > Short current.
The input power to the inverter is not recommended to exceed the
maximum rated power which show in table 5-3.
