- When 30A string fuses are utilized do NOT use input 2、3、4、7、
10、14、15、16 and 19 on either MPPT channel.
CAUTION !
M125HV_111 is compatible with 1500V/30A CE listed fuse, however, the designer
must be beware of the following requirements:
• The max Isc-stc of a connected array (sum of all paralleled strings) cannot
exceed the rated Isc limit of the inverter, that is no more than 320A total.
• Because of internal current limitations and higher string currents allowable
with 30A fuses, inputs 2、3、4、7、10、14、15、16 and 19 must NOT be
used.
