FAQ
Frequently Asked Questions | YEPV Shanghai Solar PV Fuse & Connector Manufacturer
Technical selection, ordering terms, FOB Shanghai logistics, warranty and OEM customization — answered plainly by the engineers who build and ship the products.
Selection
Provide your module power, system voltage (1000V/1500V DC) and rated current. As a reliable Chinese solar PV component exporter, our engineers will recommend matching models for rooftop, ground, energy storage and off-grid solar panel fuse protection projects.
Yes. Full series supports 1000V / 1500VDC, with rated current 30A–200A to meet residential, commercial and utility-scale power stations.
We provide 10A, 15A, 20A, 25A, 30A, 40A, 50A, 60A, 65A, 70A, 80A, 90A, 100A gPV solar fuses, covering most string protection demands of residential and commercial solar projects.
Not exactly. Breaking capacity only determines the maximum short-circuit current the fuse can safely cut off. For small rooftop solar systems with low short-circuit current, standard 10kA gPV fuses fully meet safety requirements with lower cost. For large ground PV stations and energy storage systems with high parallel short-circuit current, high breaking capacity 20kA / 30kA fuses are mandatory to avoid arc burning risks. We supply both standard and high breaking capacity gPV fuses for different PV project demands.
Ordering
Standard items have low MOQ for distributors; large EPC bulk orders enjoy flexible quantity & better unit prices.
Standard products: 3–7 working days. Custom OEM/ODM items: 12–20 working days based on mold requirements.
Small test samples are available; customers cover freight cost. Samples can be delivered within 2–4 days.
Logistics
FOB, CIF, CFR are available. Sea shipment to Europe / Southeast Asia takes 18–40 days depending on destination port. All bulk orders are shipped FOB Shanghai from our local factory warehouse.
Warranty
Standard 5-year warranty on all PV auxiliary components including our gPV fuse series. Free technical support for after-sales issues. As a responsible fast delivery solar fuse factory, we guarantee stable after-sales service globally.
Customization
1. Send drawings / requirements. 2. Quotation & sample confirmation. 3. Mold development (if needed). 4. Mass production & customized packing with customer logo. As a direct manufacturer of PV gPV fuse, we provide full OEM/ODM service for customized fuse assemblies. We complete all customized mold development & mass production in our Shanghai workshop.
Compatibility
Yes. Our inline fuse connector housing fits mainstream MC4 interface standards, including Stäubli MC4-EVO2 and general MC4 solar connectors. It can be paired with standard PV cables without additional adapters.
Quality
All our connector and fuse assemblies reach IP68 dustproof and waterproof grade. They work stably in outdoor rainy, snowy and high humidity environments for long-term solar operation.
Our core products pass TÜV Rheinland, CE, UL certifications and Retie, meeting EU, Australia, USA and Southeast Asia solar market access standards. Complete test reports can be provided for EPC tender projects.
