Photovoltaic fuses need a low minimum current, this is the main difference between photovoltaic fuses and all the others.
Hollyland's production partner for the photovoltaic sector, produces various solutions:
Fuse PV Photovoltaic fuse NH in the classic cylindrical version, to be used in combination with the appropriate fuse holders, and in the version with perforated metal fins for screw fixing directly onto the plate. Suitable for the protection of the strings of panels in photovoltaic systems thanks to a high robustness due to the particular photovoltaic application.
Fuse PV NH also called knife, they are available in various versions with voltages up to 1500V and 400A. This model is particularly suitable for the protection of the components of a photovoltaic system.
Fuse holders PV they are designed for all rated currents up to 30A at 1500V, providing the most compact and effective solution to protect 1500V circuits and equipment in photovoltaic applications. Switch disconnectors and circuit breakers complete the range.
The first thing to know is that fuses and circuit breakers are primarily used to protect the system wiring from getting too hot and catching fire. Secondly, they also are used to protect devices from catching fire or from becoming more seriously damaged if there is a short circuit. Hollyland provides a wide selection of fuses, fuse holders to improve system uptime, sustainability and reliability of photovoltaic power systems. Hollyland circuit-protection products meet the unique requirements of photovoltaic applications where issues such as heat, efficiency, longevity and global standards impact the choices in selecting protection options.
Hollyland Photovoltaic Solar Fuses are meticulously crafted for the safeguarding of DC systems up to 1500 V d.c. These fuses are tailored to provide optimal protection for various components including solar panels, combiner boxes, recombiner units, and battery storage units.
Specifically engineered for photovoltaic applications, the Hollyland PV Fuse series is purpose-built to protect photovoltaic systems effectively. Its advanced fuse construction enhances its ability to withstand constant temperature and current cycling, thereby contributing to the longevity of the system. These PV fuses from Hollyland are designed with low minimum breaking capacity capabilities, ensuring safe circuit interruption even under typical low fault current conditions commonly encountered in PV arrays.
By incorporating Hollyland PV Fuses into your off-grid or grid-tied PV system, you can shield it from unforeseen ground faults and line faults, ensuring reliable and secure operation.
