Requirements for the PV modules per input:
☐ All PV modules should be of the same type.
☐ All PV modules should be aligned and tilted identically.
☐ If inputs A and B are connected in parallel, the PV modules of inputs A and B should be
identically aligned and the same number of PV modules connected in series must be
connected to all strings of inputs A and B.
☐ The maximum inverter system voltages permitted may not be exceeded (see Section 10
"Technical Data", page 65).
☐ The maximum short-circuit current may not be exceeded (see Section 10 "Technical Data",
page 65).
☐ The positive connection cables of the PV modules must be equipped with positive DC
connectors Assembling the DC Connectors.
