5.3 DC Connection (from PV Array)
WARNING!
• When undertaking DC wiring, please ensure the correct polarities are
connected.
• When undertaking DC wiring please ensure that the DC isolator switch on
the PV array is OFF.
CAUTION!
The maximum open circuit voltage of the PV Array must not exceed 600Vdc.
The maximum recommended input power to the inverter is:
3150W (RPI H3A)/ 4200W (RPI H4A)/ 5250W (RPI H5A).
Note: The device installed between the PV Array and
inverter must meet the
rating of voltage higher than this device’s maximum input voltage.
The RPI range of PV inverters uses genuine Multi-Contact® MC4 connectors.
