After wiring, installer should choose the AC connection type on the control
panel. About setting, please refer to 5.2.7 Install Settings.
The AC voltage should be as followings:
3P3W 3P4W
L1-L2: 400 Vac ± 10% L1-N: 230 Vac ± 10%
L1-L3: 400 Vac ± 10% L2-N: 230 Vac ± 10%
L2-L3: 400 Vac ± 10% L3-N: 230 Vac ± 10%
4.4 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 connection number of PV Array, open circuit voltage and power of
all strings in DC2 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 4-4.
Type of limit RPI M30A RPI M50A
Maximum input power 35kW 52.5 kW
DC1 or DC2 23.5 kW 36.8 kW
