Standards for Balance of Systems except PV inverters: These include greater scope of design validation, safety enhancements and alignment of standards with the latest approaches for ground fault protection. 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.
The end result is that the inverter can be brought to market more quickly with a lower cost of production. 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.
New Inverters Benefit from the Updated UL 62109 Standard
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 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.
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 iecc.
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.
PV industry soon, with the main initiator being the release of the second part of the standard. In addition to the harmonization of both standards, IEC and UL have major positive cost impacts for international lec manufacturers.
Particular requirements for inverterspublished in Leading national and international organizations, involved in the development of solar power eic systems, create certification standards that dictate the safety requirements and often durability requirements of fuses used in solar systems.

New Inverters Benefit from the Updated UL Standard | Industries | UL
IEC standards for PV modules. As PV systems become more intelligent and commonplace in electrical power systems, they must also become more adaptive to changing grid oec and environmental stresses, and provide longer lifetime durations while remaining cost competitive with existing traditional power generation sources.
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.
General requirementspublished in All the Grid Tie Inverters are accompanied with their lab test report from the country of origin. 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.
Bundling safety, performance and interoperability services results in savings of both time and money.
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. UL addresses hazard prevention at a more granular level, which allows for greater flexibility in inverter design.
Solar inverter certifications: UL 1741, IEC 61683, IEC 62109
UL is the only certification organization in the world authorized to issue UL Marks. Principles, requirements and tests IEC UL specifies more than 50 different tests, which is significantly more than specified by UL The UL Mark is one of the most recognized, accepted and trusted certification marks 621009-2 the planet, appearing on nearly 22 billion products worldwide.
Secondary cells and batteries for renewable energy storage – General iwc and methods of test – Part 1: In addition, PV systems are challenged to provide a safe environment for new 62109-22 both in new installation modes implemented in newly built PV plant and building applications, as well as when integrated with existing buildings and infrastructure.
There are multiple notable advantages for manufacturers that certify their inverters to UL It is now the U. Climatic, mechanical tests and safety aspects for cabinets, racks, subracks and chassis IEC This fundamentally reduces the test efforts and the project cycling time.
Leading organizations involved in developing standards, in the field of solar power are:.
SMA believes an updated UL Standard, ULrepresents a significant step forward in harmonizing power conversion equipment safety requirements with an international perspective. Equipment to be installed outdoors IEC Since UL has not been released, an alternative had to be identified. 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.
These products can be evaluated to the standard for the U. Under this internationally recognized testing accreditation, UL can provide globally accepted evaluation reports, known as a Certification Body CB report, to inverter manufacturers. These requirements allow products designed for the international market to more easily enter the U.
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 not acceptable because of ratings or limitations within the certifications they have received.
This approach also included areas of refinement for both construction and testing requirements present in ULwhich UL had not previously addressed.
PV ground fault protection requirements to address technology and NEC code changes. PV inverter product safety certifications.
To compare, UL specifies approximately 20 different tests and they are not all obligatory since this standard was written to address all forms of DGnor are they necessarily related to PV application. Testing and measurement techniques — Surge immunity test IEC They can then apply the well-known UL Mark for the U. General requirements IEC Low voltage surge protective devices for D. 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.
Generators — Photovoltaic generators IEC NEC requirements for electrical power system compatibility. UL addresses many of the same hazards as ULyet does so in a different manner.
