3) DC Cable Connection
To ensure the optimum performance of the inverter, please read the following
guidelines before DC connection:
(a) Confirm the DC configuration referring to Table 2.5 and ensure that the
maximum open circuit voltage of the PV modules is lower than 1000 VDC
under any conditions.
(b) Confirm that the PV strings for each MPPT of the inverter are of the same
type and specification before connection. The number, orientation, and tilt
of PV strings may differ for different applications.
(c) Configure the external wiring according to the conditions in table 2.6:
WARNING: Working with live voltage is dangerous. It is
recommended to have all live circuits disabled prior to
performing connections.
