String protection

To avoid equipment damage on DC lines and

to ensure isolation of the PV system in case of

maintenance, E90 PV disconnector fuses can

be installed downstream the inverter to protect

each single string. The fuses must be selected

according to the rated current of the line and to

the maximum dissipated power.

Back-up download

When the Icc short circuit current, at the point of

installation, is greater than 100 A DC, the OVR

PVs Surge Protective Devices require a back-up

protection with a specific type gR fuse.

DC side of the inverter

For small size photovoltaic systems, E 90 PV fuse

disconnectors can be used to protect the DC

side of the inverter. The fuse should be chosen

according to the rated current of the inverter.
