Type of limit RPI M50A
Maximum input power 58kW
DC1 or DC2 35 kW
Table 4-5 : Maximum rating of input power
- 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:
Absolute maximum 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 4-5.
CAUTION !
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.
