CAUTION!
Danger due to overloading on the inverter.
This may result in damage to the inverter.
▶
Observe the maximum current carrying capacity of the various power categories
(see Table A).
▶
Only connect a maximum of 33 A to each DC terminal.
▶
Connect the DC+ and DC- cables to the correct DC+ and DC- terminals on the
inverter.
▶
Observe the maximum DC input voltage.
Table A
Power category
Maximum current carrying
capacity
MPP1 / MPP2
10.0-3 208–240 / 12.0-3 208–240
25 A / 16.5 A
15.0-3 480 / 20.0-3 480 / 22.7-3 480 / 24.0-3 480
33 A / 25 A
NOTE!
Solar modules exposed to light supply current to the inverter.
NOTE!
When using the cable inlets at the back, take care to seal them according to pro-
tection class NEMA4X before operating outdoors.
NOTE!
When connecting aluminum cables:
▶
follow all national and international guidelines regarding the connection of aluminum
cables
▶
follow the instructions of the cable manufacturer
▶
perform an annual check to ensure that the cables are firmly attached according to
the proper torque
NOTE!
When connecting DC cables, ensure the polarity is correct.
NOTE!
Form a min. 4 in. (100 mm) cable loop with all cables.
String Fuses
Only valid for the device types with the "Ecofuse" option:
The use of string fuses provides additional fuse protection for solar modules.
The maximum short circuit current I
SC
, the maximum module backfeed current I
R
, and
the specification of the maximum string fuse value in the module data sheet of the
respective solar module are decisive factors in the protection of the solar module.
The maximum short circuit current I
SC
per terminal is 15 A.
