UL addresses many of the same hazards as ULyet does so in a different manner.
If solar inverter installed is eic per iec std. Iev 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.
General requirementspublished in There are multiple notable advantages for manufacturers that certify their inverters to UL It is now the U.
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. 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 jec infrastructure.
Cables for Photovoltaic Systems.
Solar inverter certifications: UL 1741, IEC 61683, IEC 62109
The UL Mark is one of the most recognized, accepted and trusted certification isc on the planet, appearing on nearly 22 billion products worldwide. The end result is that the inverter can be brought to market more quickly with a lower cost of production.
All of these factors result in less project coordination time and ultimately, a faster product launch. IEC is based on UL and was expanded and updated to address cutting-edge safety aspects of PV power conversion equipment. General requirements IEC 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 evaluates for safety risks eic from electric shock and fire. Generators — Photovoltaic generators IEC National deviations were established in UL to allow products evaluated under IEC to be brought into the U.
New Inverters Benefit from the Updated UL Standard | Industries | UL
This must happen in parallel with technological innovation and the increased demand for cleaner energy. In ied, 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. Particular requirements for inverterspublished in These newer standards benefit from the lessons learned and result in state-of-the-art sets of requirements. Leading organizations involved in developing standards, in the field of solar power are:.
Principles, requirements and tests IEC The UL Mark can then be applied to the certified product and it can be sold in the U. Testing and measurement techniques — Surge immunity test IEC UL participates in the development of many IEC standards, with a heavy emphasis ie participation on renewable energy technical committees, and this facilitates collaboration and standards development.
New Inverters Benefit from the Updated UL 62109 Standard
Manufacturers who plan to sell their inverter products in the U. 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.
Equipment to be installed outdoors IEC ief Secondary cells and batteries for renewable energy storage – General requirements and methods of test – Part 1: 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.
