Dc Connection (From Pv Array) - Delta RPI-H3 Operation And Installation Manual

Wiring

5.3 DC Connection (from PV Array)

• 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.
• 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.
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.
