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
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
The string fuse release current can be set to greater than 15 A if required. However, a re-
lease current of 20 A must not be exceeded.
If the inverter is being operated with an external string collection box, the DC connector kit
25 (item numbers 42,0201,4479 for DC+ and 42,0201,4480 for DC-) must be used. In this
case the solar modules are externally protected in the string collection box and the metal
bolts should be used in the inverter.
National regulations regarding fuse protection must be observed. The electrician perform-
ing the installation is responsible for choosing the right string fuses.
NOTE!
To prevent a risk of fire, faulty fuses must only be replaced by new equivalent fuses.
The inverter is delivered with metal bolts as standard.
