Wiring

4.3 DC Connection (from PV Array)

- 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.
- The maximum open circuit voltage of PV array should not exceed 600Vdc.
- It is recommended to install an over current protection device between PV
array side and inverter side.
- Any device installed between PV array and inverter must have capability to
withstand the open-circuit voltage and short-circuit current of PV array.
- The input power to the inverter should not higher than the rated power shown
in Table 4-2.
