The string fuse release current can be set to greater than 15 A if required. However, a
release 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 electrical engineer
carrying out the installation is responsible for the correct choice of string fuses.
Danger due to faulty fuses.
This can result in fire.
▶
The inverter is delivered with metal bolts as standard.
