Solar fuses offer high amperage in a single case design
Littelfuse, Inc. has expanded its SPXI series in-line solar fuses to include 35
to 60 amperage models. Designed to integrate into in-line assemblies within a wire harness, these 1500VDC solar fuses protect photovoltaic (PV) installations from overloads and short circuits to minimize damage to solar panels. Key benefits of the higher amperage solar SPXI in-line string fuses include, a single body case design to increase reliability and simplify retrofitting within existing solar power systems, UL Recognized
to UL248-19 standard, with 50 kA DC interrupting rating, product labels with QR codes offering real-time access to part numbers, voltage, programming terms, and date codes to save time with product replacements and inventorying.

Power to maximize system uptime
WAGO’s Pro2 Power Supplies include six units ranging from 120-960W and
an energy conversion efficiency up to 96%. The power supplies incorporate an interface allowing them to be tailored to any application requirement. The units also offer monitoring functions that provide continuous power supply data information and signal errors for application monitoring. They also have easy fieldbus connection with snap-
on type communication modules with WAGO’s high-performance TopBoost and PowerBoost capabilities, maximizing system uptime and lowering hardware costs. TopBoost boasts 600% extra output current, enabling protection for up to
15 ms compared to conventional circuit breakers. PowerBoost provides an extra 150% output current for five seconds providing superior reserve power.

Heterojunction solar cells based on M2+ wafers
Hevel Group has launched production of heterojunction solar cells based
on M2+ silicon wafers. A slight area increase has allowed to raise the HJT solar cell peak power up to 5,88Wp
with maximum cell efficiency rate of 23.8%, while maintaining an average
of 23.3%. At the same time, Hevel HJT modules have retained their respective dimensions, while receiving a boost in yield and efficiency thanks to the M2+ transition. HJT modules with increased power output of 330Wp and 390Wp were introduced to existing glass-backsheet 60- cell and glass-glass 72-cell module series, respectively. Enhanced performance combined with minimized annual degradation, better yield in hot climate conditions and aesthetic appearance make these HJT modules a solid pick for any project, where efficiency matters.

Universally compatible rooftop attachments
OMG Roofing Products has introduced PowerGrip Universal 7 (PGU-7), a rooftop attachment anchor for mounting solar racking systems and other products to virtually any commercial roof. PGU-7 units are designed to reduce or eliminate the need for ballast in solar racking systems, so there’s less weight, material handling, and labor on the
roof. Designed with wind performance in mind, PGU-7units offer up to 2051lb/ ft (9.12 kN) of tensile strength, 1581lb/ ft (7.03 kN) of shear strength, and up
to 2214lb/ft (9.84 kN) of compressive load strength. Made of heavy-duty cast aluminum, PGU-7 units include a base ring that is secured through the roofing assembly and into the structural roof deck, as well as a waterproof cover plate to prevent water from infiltrating the system. PGU-7 units transfer wind up- lift loads to the structural roof deck for maximum strength and effectiveness. The system does not require any membrane welding, and PGU-7 units are typically installed in less than five minutes, saving both time and labor. In addition to ballast and rail-based solar racking systems, PGU-7s can be used for many other roof mounted items such as pipe supports, step crossovers, raceways, satellite dishes, small antennas, and HVAC applications.

Innovative switching solution
Southern States recently started shipping the TranSwitcher. Available at 15kV, 27kV, and 3 kV, the TranSwitcher is a simple, reliable, and cost effective solution
for mitigation of undesirable inrush currents when connecting DER to utility distribution lines. The ability to connect and disconnect the DER to the utility
line with minimal impact to the system voltage allows increased frequency
of switching, extending the life of the transformer while also reducing costs associated with transformer losses.

Single-bolt module installation in 11 seconds
Array Technologies has announced the launch of RapidClamp, a single-bolt PV module clamp technology which drastically decreases solar module installation times with First Solar Series 6 modules. RapidClamp benefits include fast, simple three-step module installation; error-proof auto-alignment of modules; pre-assembled module clamp minimizes on-site assembly; provides a reliable mounting system with integrated electrical bond; the patent pending single-bolt clamp offers no-slip octagonal torque tube clamping; and eliminates gaps between modules or protrusions above the module for simplified cleaning operations and maximum row density.
