Description
The NiuPower A6-B Max-1500 inline fuse is a DC1500V solar fuse assembly designed for reliable overcurrent protection in PV systems. It is built with weather-resistant materials and sealed to IP68 standards, making it fully waterproof for outdoor use. The fuse unit supports heavy-gauge PV cables (6–16 mm² range) – covering the common 6–10 mm² sizes – and features secure Staubli MC4/EVO2 connectors for easy plug-and-play integration.
Available in 15A, 20A, 25A, and 30A versions, this inline fuse delivers dependable high-current performance. As a NiuPower product, it carries the brand’s reputation for quality – NIU’s solar connectors are “engineered for unmatched reliability” and widely used in PV installations globall.
NiuPower Inline Fuse, DC 1500V with 15A/20A/25A/30A Connector MC4/EVO2
The A6-B Max-1500 inline fuse unit is engineered for high-current PV strings. It is rated for DC 1500V and can handle large cable sizes (up to 16 mm²).
SolarRains stocks the 15–30A variants of this model.
The casing is IP68 rated and UL94-V0 flame-resistant, ensuring durability and safety in all weather. Inside, a high-quality fuse element provides fast interruption of overcurrents. A locking mechanism (NEC type) and Staubli MC4/EVO2 connectors make installation secure and tool-free. By using low-resistance contacts, the fuse maximises efficiency with minimal voltage drop.
In summary, the Niu Power A6-B Max-1500 inline fuse combines industry-standard safety with long-term reliability for solar string protection.
Key Features of NiuPower Inline Fuse

Main Benefits
The NiuPower inline fuse delivers durability and reliability in harsh environments. Its IP68-rated, weatherproof housing and UV-resistant materials ensure it stands up to rain, dust and extreme temperatures (–40°C to +65°C) without corrosion or failure. This makes it ideal for rooftop and ground-mounted solar arrays, where long-term outdoor performance is essential.
Compatibility is a key benefit. The A6-B Max series supports large PV cables (up to 16 mm²) and uses standard MC4/EVO2 connectors, so it plugs directly into common solar panel strings and combiner boxes. Whether you’re using 6 mm² or 10 mm² wire, and whether your system uses MC4 or the new EVO2 style plugs, this fuse adapts to your setup. It meets IEC and UL 1500V standards and carries UL94-V0 safety certification, giving design engineers and electricians confidence that it conforms to strict PV safety regulations.
Safety is also enhanced by this inline fuse. In an overcurrent event it quickly interrupts the circuit, protecting panels and wiring from damage. The flame-retardant casing and high breaking capacity (10 kA@1500V) mean the unit can safely contain electrical faults. NIU’s reputation for quality components further assures installers that the product will perform as needed under fault conditions.
Finally, the design simplifies installation. The fuse unit comes fully assembled: just plug the MC4/EVO2 ends into your string, lock them securely, and you’re done. The inline form factor makes it easy to add protection without rewiring – you simply insert it in series with a string of panels. This time-saving, tool-free setup suits EPC contractors and installers who need quick, reliable solutions on-site.

NiuPower Limited (NiuPower)
NiuPower is a global leader in solar electrical connectors and wiring solutions. The company offers over 5000 products (many TUV and UL certified) for photovoltaics, energy storage, and EV applications. Engineers and installers choose NIU for its quality and innovation: NIU connectors are “the preferred choice for solar installations worldwide” due to their superior safety and efficiency. NIU’s product range includes modules for harsh environments with ISO 9001 certification, reflecting its commitment to high standards. In short, NiuPower is trusted internationally for robust, high-performance solar components.
Installation is straightforward. This inline fuse plugs directly into your solar string like any MC4 connector. First, turn off the PV system. Then connect the fuse’s MC4/EVO2 male end to the female panel leads, and the female end to the combiner box or inverter input. Make sure the connectors “click” and lock. Position the fuse unit along the cable run (it can hang or be clipped in place). Finally, restore power. The fuse will then sit in series, protecting the string. No special tools are needed beyond standard solar connector wrenches.
It is designed for standard solar PV wiring. The A6-B Max-1500 accepts solar cable from 6 mm² up to 16 mm² cross-section. In practice, this covers the common 6 mm² to 10 mm² sizes used on many arrays. The ends come fitted with Staubli MC4/EVO2 connectors, which match virtually all solar panels and combiner inputs. If your setup uses MC4, it will plug right in. If you use the newer EVO2 connectors, the EVO2 version will work too. In short, it’s compatible with the usual MC4/EVO2 DC plugs and cables in PV installations.
SolarRains offers the Niu A6-B Max-1500 inline fuse in 15A, 20A, 25A, and 30A versions. Choose the one that matches or slightly exceeds your expected string current. (NIU’s Big Max series even goes up to 80A for very large systems.) Always select a fuse rating that safely protects your cables and panels without nuisance tripping.
This fuse is used wherever you need series protection on the DC side of a solar system. Common use cases include rooftop or ground-mount PV strings, solar farms, and solar + storage systems. It sits between a string of panels and the inverter or combiner box. Designers like using it to meet safety standards and protect against overcurrent. Because NIU connectors are widely used in photovoltaics, you’ll find it in residential, commercial and utility solar projects around the world. Its robust design also suits challenging environments (e.g. farms, deserts) that demand weather-resistant gear.
Yes. If the inline fuse blows (opens) due to a fault, you can replace it by simply disconnecting it and plugging in a new unit of the same type. Always turn off the array before doing this. Since the fuse element is built into the sealed unit, you typically replace the whole fuse assembly rather than just the element. Make sure to reinstall with the same rating (15A, 20A, etc.) as the original.
Solar Rains stocks replacement Niu A6-B Max-1500 fuses, and NIU also provides replacement units. Follow all safety procedures when replacing fuses.
