NEW LINE OF LITTELFUSE 1500 VDC PHOTOVOLTAIC FUSES PROTECTS NEXT GENERATION OF SOLAR EQUIPMENT

Littelfuse offers the broadest selection of fuse options

CHICAGO, June 17, 2013 –- Littelfuse, Inc., the global leader in circuit protection, today announced it has developed in cooperation with leading photovoltaic equipment providers a Series of 1500 VDC photovoltaic fuses designed to protect the next generation of solar installations. The SPXV and SPXN Series of fuses meet the tough requirements of 30kA interrupt ratings, 1500 VDC protection and global standards critical to solar equipment manufacturers.


The new SPXV series includes string protection fuses from 6 to 20 amps in a 10 x 85 mm design and slightly wider 25 and 30 amp fuses, designed to fit the same holders. The standardized size allows for maximum flexibility of array construction, as fuse rating is often a final step in specification. With eight products under 30 amps, Littelfuse offers the broadest selection of fuse options. All of the new string protection fuses fit into a new 1500 V LPXV holder.

The higher amperage SPXN, with six models ranging from 200 to 400 amps, also comply with global standards, including UL2579 and IEC 60269-6. These products feature a ventilation-enhancing, cylindrical design, with sturdy melamine construction that meets the standard NH3L package size. The blade and bolt mounting feature provides flexibility in mounting for easy installation and replacement.

Both the high and low amperage models were specifically designed to minimize wattage loss and provide the highest efficiency product for 1500 VDC installations. This not only improves long-term system cost; it also reduces internal cabinet temperatures.

"With our innovative new 1500 VDC product offering, we are well positioned to support the design leaders in the solar industry," stated Dan Gilman, Director of Global Sales. "Our work with major OEM partners and our application knowledge have enabled us to develop a 1500 VDC solution that meets global standards and also provides high levels of efficiency."

The 1500 VDC SPX Series augments the SPF and SPFJ fuses for 1000 VDC protection, as well as other photovoltaic protection products. Littelfuse is a leader in the solar market, providing a broad range of products and support for customers around the globe.

SolarEdge Technologies - EV Charging Single Phase Inverter

SolarEdge Technologies - EV Charging Single Phase Inverter

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
