Holyland / Hollyfuse PV Fuses and Protection
In PV systems, the current can easily exceed the operating current and reach a level that can cause overheating and damage. The fuses in this case behave like switches, if too high a current passes through them the internal filament overheats and melts, breaking the circuit.
To ensure the best possible protection for the system and for the people working on the equipment, fuses are always applied to both poles, positive and negative. In this way, the fuses will isolate the string of the plant concerned, allowing the photovoltaic system to continue generating electricity.
Hollyfuse supplies high quality PV fuses for DC applications in the photovoltaic industry. Hollyfuse has a wide range of Cylindrical and NH Blade fuses perfect for your photovoltaic designs. We also carry PV System protection accessories, such as fuse holders, combiner boxes, and switches. World Products can assist you with any technical, procurement, or sample inquiries.

CHARACTERISTICS OF THE FUSES USED IN PHOTOVOLTAIC PANELS
Photovoltaic fuses need a low minimum current, this is the main difference between photovoltaic fuses and all the others. Fuse PV 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.
Hollyfuse offer a range of protection components for PV and EV applications.
Photovoltaic fuses are used for protecting and isolating PV cells and storage units. Hollyfuse offer products from 1amp to 630amp with voltages up to 1500v. Approvals cover UL, TUV CGC & CUL. PV class operation with easy mount options and high anti-overload protection, with a range of accessories to suit all applications.

There are two versions of contacts, knife type to use in fuse bases and bolted version to mount directly on busbar. They provide protection against overloads as well as short-circuits (gPV class according to IEC60269 and UL248-19 Standards, with a minimum fusing current of 1,35·In. Made with ceramic body with high withstand to internal pressure and thermal shock. Contacts are made in silver plated copper or brass and melting elements are made in pure silver in order to avoid the aging and thus keep unalterable the electric characteristics. They have a low power losses values to get a good efficiency
