New Inverters Benefit from the Updated UL 62109 Standard
These include greater scope of design validation, safety enhancements and alignment of standards with the latest approaches for ground fault protection. IEC is based on UL and was expanded and updated to address cutting-edge safety aspects of PV power conversion equipment.
PV industry soon, with the main initiator being the release of the second part of the standard. If solar inverter installed 6209-2 as per iec std.
New Inverters Benefit from the Updated UL Standard | Industries | UL
Surge Protective Devices connected to the D. The need for only one project to complete product evaluation, testing and certification to the standard maximizes the coverage of certification budgets and accelerates product market entry. UL is the only certification organization in the world authorized to issue UL Marks.
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. SMA believes an updated UL Standard, ULrepresents a significant step forward in harmonizing power conversion equipment safety requirements with an international perspective. They can then apply the well-known UL Mark for the U.
In summary, achieving UL certifications to product safety standards help manufacturers like SMA demonstrate that a product operates more safely with expected normal use, as well as under foreseeable abnormal conditions. Low voltage surge protective devices for D.
This approach also included areas of refinement for both construction and testing requirements present iev ULwhich UL had not previously addressed. This work includes significant revisions to the U. There are multiple notable advantages for manufacturers that certify their inverters to UL UL will retain the requirements for grid interactive products, 6210-92 the linkage and references to the IEEE series of standards. For example, UL is the most widely accepted international PV power conversion standard and corresponding certifications help to future-proof inverter designs.
As stated earlier, UL is a standard written for PV inverters only, which benefits customers because it means that inverters are now undergoing more testing to help ensure safety, reliability and functionality.
Photovoltaic system performance monitoring EC These requirements allow products designed for the international market to more easily enter the U. UL participates in the development of many IEC standards, with a heavy emphasis on participation on renewable energy technical committees, and this facilitates collaboration and standards development.
It is now the U. Photovoltaic off-grid application IEC Ed.
Standards for Balance of Systems except PV inverters: UL specifies more than 50 different tests, which is significantly more than specified by UL In the end-product application, UL Recognized Components may sometimes need additional evaluation to function correctly and safely due to the environment in which they reside. Particular requirements for inverters IEC The end result is that the inverter can be brought to market more quickly with a lower cost of production.
This fundamentally reduces the test efforts and the project cycling time. General requirementspublished in Leading organizations involved in developing standards, in the field of solar power are:. The UL Mark can then be applied to the 6210-2 product and it can be sold in the U.
All of these factors result in less project coordination time and ultimately, a faster product launch. PV inverter product safety certifications.
Equipment to be installed outdoors IEC SMA is the first inverter manufacturer to have a product on the market with a V, UL certification.
UL addresses many of the same hazards as ULyet does so in a different manner. Climatic, mechanical tests and safety aspects for cabinets, racks, subracks and chassis IEC In addition, PV systems are challenged to provide a safe environment 6210-92 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.
Principles, requirements and tests IEC These newer standards benefit from the lessons learned and result in state-of-the-art sets of requirements. 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 components used in the end-product design and provide guidance if some components are iev acceptable because of ratings or limitations within the certifications they have received.
In addition to the harmonization of both standards, IEC and UL have major positive cost impacts for international inverter manufacturers.
