With over 60 million devices installed in solar power systems, Littelfuse understands the challenges facing the photovoltaic market. Our solar-rated fuses, relays, TVS diodes, varistors, power distribution blocks, dc disconnect switches, surge protective devices and other products help protect equipment in PV applications.
The building of a solar infrastructure can depend on economic drivers and the pressure to achieve parity with traditional electrical power sources. Therefore, cutting costs and increasing the output of a photovoltaic (PV) system is a priority. By adding in proper solar circuit protection, a more economical architecture can be designed, equipment is safeguarded, downtime is reduced, and safety is improved, creating a more efficient and cost-effective PV system with maximum output.

A leading integrated cabling and switch manufacturer was using outsourced solar fuses that were not performing in excessive heat. To help reduce and eliminate these failures, the manufacturer was installing a higher amperage fuse, at a higher cost. They were also incurring the added costs of physically replacing the blown fuses sooner than normal and needed a new solution quickly.
Littelfuse stepped in with their SPXI and SPXV 1500 V dc solar fuses and fuse holders. The performance and quality of these products impressed the manufacturer. In addition, Littelfuse worked with the manufacturer to take into account the time-sensitivity of the project and provide an inventory strategy that would work for them. With better, more reliable performance, the Littelfuse solar fuses and fuse holders saved the manufacturer costs while preventing downtime.
An OEM of solar power systems was designing energy storage systems that incorporated a new, more efficient inverter. This inverter relied on a high-power insulated gate bipolar transistor (IGBT) that operates at both high voltage and high current which, if not protected, could lead to thermal runaway, destruction or even fire.
If the inverter failed, and caused the energy storage system to be offline, it could force an electric utility to buy power at a premium to meet peak demand.
Read how Littelfuse exceeded the OEM’s requirements with the PSR series of high-speed semiconductor fuses to prevent catastrophic failure.
According to Forbes, of all renewable energy generation, solar PV is expected to grow the fastest from now through 2050… As PV systems have grown in size, so have the corresponding voltage requirements. This increase in system voltage has typically been intended to minimize power loss associated with long conductor runs. Standard circuit protection devices are not designed to protect photovoltaic components. Learn how our variety of solar fuses meets this growing demand for photovoltaic energy and offers solutions that save time and money.

PV systems are usually located in large open spaces, in fields, or on the tops of buildings which make them vulnerable to weather systems as well as hard to access. Lightning, an electrical discharge in the atmosphere, indirect lightning, and fires caused by the release of energy can all create voltage surges. These surges can cause equipment damage or failure, downtime, and/or data loss, let alone jeopardize the safety of personnel. To avoid this, surge protective devices (SPDs) are installed to prevent these unpredictable hazards. Check out this guide and videos for more information:

The Class J Fuse Disconnect Switch combines a switch and multiple fuses in a single, compact device. This switch, with both front or side operation, offers a simpler way to manually open and close a circuit while safeguarding against overcurrent and short circuits. When it detects an overload or short circuit, the fuse blows automatically to open or break the circuit both upstream and downstream and shuts off the equipment.

The Littelfuse series of arc-flash relays significantly reduce arc-fault damage by detecting the light from an arc flash and rapidly providing a trip signal. The compact designs can be surface or DIN-rail mounted making them ideal for combiner boxes with little available space and central inverters.
