In power system, fuse is used to protect electronic component from overcurrent
damage, component might deviate, overheat, damaged or even cause fire hazard.
Proper fuse rating should be chosen according to pv module parameters and related
regulations, fuse with too high rating cannot provide protection, fuse with too low
rating affect normal operation.
Lower limit of fuse rating should be calculated from short circuit current of pv
module.It is recommended to use 1.56 Isc if there's no special requirement by local
regulation.
according to above method, user can calculate fuse rating according to pv module
parameters. For example, Isc of pv module is 10A, then fuse current rating is
recommended to be 10A x 1.56 15A, voltage range of pv array is 0– 1000V, so rating
of fuse is 1000V/15A .
Maximum pv array voltage is 1000V, so rating of DC breaker in combiner box should
not be lower than 1000V, ATESS combiner box uses 4 pole breaker with 2 pole
connected in series, the breaker can withstand 1000V high voltage to meet solar plant
requirement.
