Sources estimate rising demand from consumers, commercial and utilities will translate into tremendous growth for the solar energy market in the coming years. And while the market for solar energy grows and the technology and equipment used to harness and distribute photovoltaic power continues to evolve, the one constant is the need to protect workers and equipment from potential electrical hazards. Over the past several years, Mersen has invested countless resources, expertise, and initiative contributing toward developing the proper codes, standards, and products mandated by the solar power industry.

Visit Mersen at booth # 2709 to view recent solar innovations developed by Mersen:

• HelioProtection® fuse line, the industry's first UL 2579 listed range of dedicated photovoltaic fuses, provides superior overcurrent protection at the combiner box and inverter levels and covers applications ranging from 1 to 400A, up to 1500VDC. The enhanced fuse construction of the HelioProtection series makes it ideal for continuous temperature and current cycling withstand adding to system longevity. Low minimum breaking capacity capabilities of 1.35 times the fuse-rated current value allow for safe circuit interruption under typical low-fault current conditions produced by PV arrays. The HelioProtection fuse line includes the HP6M, HP10M, HP15M, HP6J, HP10J, HP10NH and HP15NH series.

• HP10J photovoltaic fuses: the newest and most efficient UL 2579 listed photovoltaic fuse – the HP10J, an exciting addition to the existing HelioProtection® fuse line, which already includes the HP6M, HP10M, and HP6J. The new HP10J photovoltaic fuse line provides superior overcurrent protection at the re-combiner box and inverter levels and covers applications ranging from 70A to 400A, 1000VDC.

• The New PV Safety System featuring Greeneye and Greenbrain devices. The Mersen PV safety solution provides an individual, remotely controlled shutdown feature per PV module, meeting the requirements of NEC690.12 and safeguarding against potential electrocution hazards of PV installations. The shutdown feature can be remotely controlled two ways: manually by hitting the emergency stop button or automatically by a DC arc detector or any other safety system to shut down the PV array. In case there is a need for urgent shutdown, when activated, the Mersen PV Safety Solution brings the output current and voltage of the individual PV modules to zero. The PV installation therefore becomes fully disconnected; safe for electrical workers performing construction and maintenance or, in the event of fire, safeguarding responding firefighters from risk of electrocution.

• PV String Monitoring Solution: In mid- and large-scale photovoltaic (PV) installations, it is mandatory to properly monitor the string level production over time to guarantee long term power performance by maximizing energy production, optimizing facility management, and decreasing operations and maintenance costs. Mersen delivers a string monitoring solution to be installed in the string combiner box.

• USGM-HEL Fuseholders are equipped with industry-proven and patented CAGE CLAMP® technology. Mersen is the first manufacturer to offer this technology in a power fuseholder. This screw-less, spring pressure, wire termination technology has over 25 years of field experience and acceptance and can reduce wire installation time and cost by up to 75%. CAGE CLAMP technology significantly improves system reliability by maintaining a very low contact resistance easily withstanding corrosion, vibration, and temperature cycling. The technology also eliminates the need for routine torque maintenance required by standard screw-type terminations.

• Surge-Trap® Modular and Pluggable Surge Protective Devices (SPDs) are specifically designed with the photovoltaic industry in mind. Surge-Trap Modular and Pluggable SPDs are DIN-rail mountable and feature Mersen's patented TPMOV® technology inside. No additional overcurrent protection required.

Visitors to the booth can also view a demonstration of the new PV safety system as well as test their knowledge of electrical protection with an interactive Protection Intelligent Quotient (PIQ) Quiz.
