* The inverter enters 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 1,000 V, the MC4 connectors
included in the scope of delivery must not be used. In this case MC4-Evo2 connectors must
be used.
** The voltage difference between MPPTs should be less than 150 V. The voltage of the con-
figured string should be higher than the lower limit of the rated MPPT voltage.
*** For inverters without a DC switch, it is necessary to prepare an external DC switch ac-
cording to AS 60947.3.
