5.3 DC Connection (from PV Array)
The maximum open circuit voltage of the PV Array must not exceed 600Vdc.
The maximum recommended input power to the inverter is:
*with unbalanced input power
CAUTION !
WARNING !
• When undertaking DC wiring, please ensure the correct polarities are
connected.
• When undertaking DC wiring please ensures that the DC isolator switch
on the PV array is OFF.

The device installed between the PV Array and inverter must meet the rating
of voltage higher than this device’s maximum input voltage.
NOTE
5.3.1 Asymmetrical Loading
The inverters operate using two separate MPP trackers that can handle both symmetrical
and asymmetrical loads to allow for optimum adjustment. This allows for the requirements
of complex PV system designs to be fulfilled. For example: east/west-facing roof
(symmetrical load) or a south facing roof such as a dormer (asymmetrical load).
