4.3. DC Connection (from PV Array)
WARNING！
• When undertaking DC wiring, please ensure the correct polarities are
connected.
• When undertaking DC wiring please ensures that the power switch on
the PV array is OFF.
CAUTION！
• The connection number of PV Array, open circuit voltage and power of
all strings in DC1 must be coherent.
• The maximum open circuit voltage of PV Array cannot exceed 1000V.
• Any device installed between PV Array and inverter must meet the
following specifications:
Rated voltage > open-circuit voltage of PV Array.
Rated current > short-circuit current of PV Array.
• The input power to the inverter should not higher than the rated power
shown in table 4-3.
