* 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.
** Please note the min. voltage without MPP tracker derating is 303V (+5%) for SG10/15/
20RT and 236V(+5%) for SG5.0/7.0/8.0RT @AC230V 12.5A.
*** The voltage difference between MPPTs should be less than 150 V. The voltage of the
configured string should be higher than the lower limit of the rated MPPT voltage.
