5.3 DC Connection (from PV Array)
• The maximum open circuit voltage of the PV Array must not exceed
600V (RPI-H3) / 1000V (RPI-H5).
•
The recommended PV power connect to inverter is 3600W (RPI-H3) /
5950W (RPI-H5).
•
The device installed between PV Array and inverter must meet the rating of
voltage higher than this device’s maximum input voltage.
CAUTION !
WARNING !
• When doing DC wiring, please choose the proper wiring by connect to the
correct polarity.
• When doing DC wiring, please confirm that PV Array’s power switch is off.
DC wiring polarities are divided into positive and negative, which is as shown in
Figure 5-5.
The connection shall be coherent with the indication marked on inverter.
