PV 13 A cylindrical fuse link

Fuses with gPV characteristics are used to protect the PV system against overcurrent.

Overcurrent protection

PV systems consisting of three or more rows of solar panels connected in parallel must be protected in each row with a suitable gPV fuse. PV systems with less than 3 rows of solar panels do not generate such surges that could damage solar cables or panels. Usually 2 gPV fuses (+ and - poles) are used to protect against overcurrent in cables and solar panels in one row of solar panels. In case of damage, the fuses cut off the damaged row of solar panels. Other rows of PV panels can continue to generate electricity.
