Frequently Asked Questions (FAQ)

Q: What is the primary function of the FKPV-32-2 fuse in a PV system?
A: Its primary role is to provide overcurrent protection for DC circuits within a solar power system. It safeguards strings of solar panels, wiring, and inverter inputs by interrupting the circuit if the current exceeds the safe 32A rating, preventing damage from short circuits or overloads.
Q: Can this fuse be used for both AC and DC applications?
A: No. The FKPV-32-2 is specifically designed and rated for Direct Current (DC) applications, particularly the low-voltage side of photovoltaic systems. Using an AC-rated fuse in a DC circuit can be unsafe and is not recommended.
Q: How do I select the correct current rating for my PV string?
A: The fuse rating should be selected based on the maximum possible current (Impp) of the PV string, typically with a safety margin. Common practice is to choose a fuse rating 1.25 to 1.56 times the string's rated current. Consult your system design or a qualified engineer for precise selection.
Q: What are the mounting options for this fuse?
A: This fuse is designed for easy installation. It typically supports panel mounting via its end caps or can be installed on a standard DIN rail using an appropriate fuse holder, which offers flexibility for different enclosure designs.
Q: Does the fuse have any specific certifications for solar applications?
A: As a manufacturer adhering to ISO9001 and other quality standards, our products are designed to meet relevant industry requirements. Specific certifications for the fuse (e.g., UL, TUV) are available upon request, as our product range may include certified models.
Q: What happens after the fuse blows? Is it replaceable?
A: Yes, the FKPV-32-2 is a replaceable cartridge fuse. Once it has operated (blown) due to a fault, it must be replaced with an identical fuse of the same rating and type after the fault condition has been identified and resolved.
Q: Is this product suitable for outdoor use in combiner boxes?
A: Its ceramic construction provides good environmental resistance. However, it should be installed within a properly rated and sealed enclosure (like a combiner box) that provides protection against dust and moisture ingress according to the system's environmental rating.
Q: What is the lead time and shipping origin for bulk orders?
A: We support efficient logistics through major Chinese ports like Shanghai, Ningbo, and Guangzhou. Lead times for bulk orders are competitive, and we cater to a global market, ensuring reliable delivery to destinations in North America, Europe, Asia, and other regions.
