Photovoltaic standardization

Climatic, mechanical tests and safety aspects for cabinets, racks, subracks and chassis IEC All the Grid Tie Inverters are accompanied with their lab test report from the country of origin.

Surge Protective Devices connected to the D. 61209-2 for Balance of Systems except PV inverters: These newer standards benefit from the lessons learned and result in state-of-the-art sets of requirements. Photovoltaic off-grid application IEC Ed.

Solar inverter certifications: UL 1741, IEC 61683, IEC 62109

Generators — Photovoltaic generators IEC The need for only one project to complete product evaluation, testing and certification to the standard maximizes the coverage 61209-2 certification budgets and accelerates product market entry. UL will retain the requirements for grid interactive products, including the linkage and references to the IEEE series of standards.

Low voltage surge protective devices for D. The result was an evaluation addressing the classic safety challenges addressed in ULwith the additional evaluation of new risks for inverters and distributed generation products through the application of a modern, streamlined methodology. In particular, SMA helped develop the requirement for current measurement in combination with the ground fault detecter interrupter GFDIwhich provides additional safety aspects for the detection of ground faults, while an increasing leakage current can be detected and monitored much earlier.

Cables for Photovoltaic Systems. Since UL has not been released, an alternative had to be identified. In addition, PV systems are challenged to provide a safe environment for new technology both in new installation modes implemented in newly built PV plant and building applications, as well as when integrated with existing buildings and infrastructure.

The following standards list requirements for solar inverters such as the desired nameplate information, requirements for safe operation of inverters, procedures for measuring efficiency, general standard for inverters connected in independent power system, and many other requirements. Particular requirements for Low-voltage switchgear and controlgear assemblies intended to be installed in places where unskilled persons have access for their use – Distribution boards IEC UL evaluates for safety risks including from electric shock iwc fire.

New Inverters Benefit from the Updated UL 62109 Standard

62109-22 Under this internationally recognized testing accreditation, UL can provide globally accepted evaluation reports, known as a Certification Body CB report, to inverter manufacturers. There are multiple notable advantages for manufacturers that certify their inverters to UL This approach also included areas of refinement for both construction and testing requirements present in ULwhich 621092 had not previously addressed. Secondary cells and batteries for renewable energy storage – General requirements and methods of test – Part 1: Other national differences include references to UL for grid interactive product requirements and expansion of the requirements for multi-mode products that operate both grid-tied and stand-alone.

PV industry soon, with the main initiator being the release of the second part of the standard. This work includes significant revisions to the U. If solar inverter installed is as per iec std. In addition to the harmonization of both standards, IEC and UL have major positive cost impacts for ie inverter manufacturers.

It is now the U. SMA believes an updated UL Standard, ULrepresents a significant step forward in harmonizing power conversion equipment safety requirements with an international perspective.

UL addresses many of the same hazards as ULyet does so in a different manner. NEC requirements for electrical power system compatibility.

New Inverters Benefit from the Updated UL Standard | Industries | UL

The UL Mark can then be applied to the certified product and it can be sold in the U. PV inverter product safety certifications. IEC standards for PV modules. UL will also continue to be used to evaluate non-PV power conversion equipment such as microturbines, generators, wind turbines, fuel cells, and the like. As PV systems become more intelligent and commonplace in 26109-2 power systems, they must also become more adaptive to changing grid conditions and environmental stresses, and provide longer lifetime durations while remaining cost competitive with existing traditional power generation sources.

IEC is based on UL and was expanded and updated to address cutting-edge safety aspects of PV power conversion equipment. SMA found the opportunity to have this technical guidance to be a unique benefit of working directly with UL instead of another third-party certifier.

The end result is that the inverter can be brought to market more quickly with a lower cost of production. For example, UL is the most widely accepted international PV power conversion standard and corresponding certifications help to future-proof inverter designs.

Equipment to be installed outdoors IEC Principles, requirements and tests IEC While some standards are mandatory violators may be prosecuted as per lawothers are just for elevating the product standard and to include industry best practices and benchmarks.

Utilities and authorities having jurisdiction AHJs require distributed generation that is reliable, safe, compatible with the requirements of the National Electrical Code NECand has been tested and constructed to withstand the rigors of daily, full power operation without significant amounts of downtime.

While based on the foundation of ULIEC is somewhat different because IEC it was specifically developed to also address not only known gaps in UL but also the challenges of emerging PV power conversion technologies. Particular requirements 621009-2 inverterspublished in UL is the only certification organization in the world authorized to issue UL Marks.

UL certifications assess not only the safety performance of an end product through testing, they also review and validate the design via a thorough assessment of the safety-critical 62019-2 used in the end-product design and provide guidance if some components are not acceptable because of ratings or limitations within the certifications they have received. General requirementspublished in National deviations were established in UL to allow products evaluated under IEC to be brought into the U.

Leading organizations involved in developing standards, in the field of solar power are:.
