Note(3): The inverter enters the standby state when the input voltage ranges between 1,000
V and 1,100 V. If the maximum DC voltage in the system can exceed 1000 V, the MC4 con-
nectors included in the scope of delivery must not be used. In this case MC4 Evo2 connec-
tors must be used.
Note(4):
• The voltage difference between MPPTs should be less than 80 V.
• The voltage of the configured string should be higher than the lower limit of the rated
MPPT voltage.
