String fuse requirements

In string inverter systems, a line-line fault can create a critical reverse current. To protect the PV modules, string overcurrent protection is necessary if the PV module rating is insufficient. However, even with string fuses, when the current is lower than the module rating there is a current at the fault location, and it may cause a fire.
