Product FAQ
How is PV Fuse different from ordinary fuses?
PV Fuse is designed for photovoltaic systems, with higher rated voltage (usually above 1000V) and breaking capacity, and can reliably cut off DC fault currents up to 1500V. Ordinary fuses have lower rated voltage and breaking capacity.
How big is the breaking capacity of PV Fuse in general?
The breaking capacity of high-quality PV Fuse can reach 30kA and above, which can effectively cut off extremely high fault currents and protect the safety of photovoltaic systems.
What should be paid attention to when installing PV Fuse?
During installation, a suitable fuse holder should be selected and reliable contact should be ensured. Live operation is strictly prohibited. Check the terminal regularly to avoid overheating.
How to correctly select the rated current of PV Fuse?
It is necessary to comprehensively consider the short-circuit current, rated current and other parameters of the photovoltaic string, and leave a certain margin. Usually the rated current should be greater than 1.25 times the short-circuit current of the string. Consult professionals when necessary.
If the PV Fuse blows frequently, what are the possible reasons?
It may be due to improper selection and low rated current; or it may be due to faults in the PV string, such as hot spots, short circuits, etc. The cause of the fault needs to be carefully investigated and handled in a timely manner.
