Sungrow and TÜV Rheinland Redefine Industry Rule: World’s First Inverter Long-Term Reliability Corporate Standards Released

Published

on

MUNICH, July 13, 2026 /PRNewswire/ — During the Intersolar Europe 2026 exhibition, Sungrow and TÜV Rheinland jointly launched the world’s first quantitative long-term reliability standards for PV inverters, including 2 PfG 3325 Reliability test qualification for IGBT modules in photovoltaic power systems and power electronic converter systems and 2 PfG 3328 – Part 2 Specifications for Reliability Testing and Assessment of Power Electronic Products – Part 2: Power Conversion Equipment (PCE).

Sungrow’s SG510HX string inverter and its IGBT modules were among the first products certified under the two standards, providing early validation of the framework in practical applications.

Meeting the Demands of Modern PV Plants

As PV power plants continue to expand into increasingly demanding environments such as deserts, offshore locations, and high-altitude regions, ensuring inverter reliability over 25 years of operation has become increasingly important for project owners and investors. However, existing reliability qualification methodologies were not originally designed to fully capture the increasingly diverse and demanding operating conditions of modern PV plants, creating a gap between laboratory qualification and long-term field performance.

To address this challenge, Sungrow and TÜV Rheinland have developed a comprehensive reliability evaluation framework that enables a more scientific, quantitative, and traceable assessment of inverter lifetime performance.

From Systems to Components: A Unified Reliability Validation Framework

Facing the shortcomings of traditional standards, the dual framework establishes a robust, quantifiable reliability methodology spanning the entire “system-component” validation continuum.

2 PfG 3325 (IGBT Reliability Test Standard) is a component-level standard, addressing the failure mechanisms and lifetime models of power semiconductors under stresses such as thermal cycling and power cycling. 2 PfG 3328 – Part 2 is a system-level reliability verification standard, focusing on the performance degradation and lifetime assessment of PV inverter complete machines under complex environmental stresses, with core emphasis on verifying the product’s environmental adaptability within the designed service life.

Together, the standards establish a system-to-component validation chain: 2 PfG 3325 provides a quantitative data basis for inverter -level reliability modeling and supplier evaluation, while 2 PfG 3328 – Part 2 defines a unified inverter -level validation framework with testable and traceable criteria.

New Standards Upgraded for Complex Scenarios

Addressing the issue of insufficient coverage in traditional standard scenarios, the standards added several enhanced test items designed for complex operating conditions.

At the system level, 2 PfG 3328 – Part 2 covers long-term durability, environmental adaptability, and grid-connected operation under diverse operating conditions, with additional requirements such as 4,000-hour accelerated aging tests and continuous low- and high-voltage ride-through verification.At the IGBT level, 2 PfG 3325 strengthens conventional qualification methods by extending HTGB testing to 168 hours at 1.1 × VGES and introducing an additional 500 temperature cycles under mechanical loading conditions beyond the standard 2,000-cycle thermal cycling requirement.

The standards significantly strengthen reliability verification by expanding test coverage for complex operating scenarios.

Quantifiable Lifetime Assessment

To improve the quantitative assessment of long-term field reliability, the standards establish data-driven lifetime models based on extensive field performance data from PV power plants. The standards also draw on automotive components’ reliability testing and quality verification standards such as VW 80000 and GMW 3172, adopting more stringent test approaches to evaluate long-term stability under complex operating conditions.

“The two standards establish a structured and verifiable framework for long-term inverter reliability evaluation, offering valuable references for manufacturers, investors, and insurers in assessing lifecycle performance,” said Thomas Haupt, Vice President of Solar & Commercial Products, European Region of TÜV Rheinland Group.

Why Sungrow

As the pioneering architect of these standards, Sungrow leveraged its 29 years of expertise in power electronics together with extensive global project experience and operational insights across diverse climates and applications. Steering the reliability evaluation of PV inverters away from subjective empirical deductions toward a scientifically quantifiable, verifiable, and traceable future.

Niutech Signs Agreement with Global Energy Major for Waste Plastic Pyrolysis Line to Produce SAF

Published

on

By

JINAN, China, Aug. 29, 2026 /PRNewswire/ — Niutech Technology Group Co., Ltd (abbreviated as “Niutech”), a STAR Market-listed Chinese company specialized in industrial continuous pyrolysis technology, today announced it has signed a sales agreement with a global energy major for an Industrial Continuous Waste Plastic Pyrolysis Production Line. The line runs on Niutech’s proprietary patented pyrolysis technology and delivers safe, environmentally sound operation with a single-unit processing capacity of 10,000 to 50,000 tons per year (tpy). The agreement marks Niutech’s first entry into the customer’s equipment supply chain and the start of a long-term partnership.

As part of its sustainability commitments, the customer has steadily expanded investment in renewable energy in recent years and made Sustainable Aviation Fuel (SAF) a strategic priority. Under the agreement, Niutech’s technology and equipment will be deployed to upgrade a large refinery owned by the customer. Once complete, the refinery will have an integrated capability from pyrolysis oil to hydrotreated SAF.

SAF is widely regarded as a key pathway for aviation decarbonization. Under the EU’s ReFuelEU Aviation regulation, SAF blending in jet fuel is mandatory at 2% from 2025, rising to 6% by 2030 and 70% by 2050, while the UK and Singapore have enacted their own blending mandates. Used cooking oil (UCO) is currently the dominant feedstock for SAF production, but limited UCO supply has left the market in urgent need of alternatives. Through Niutech’s patented technology, waste plastics can be converted into pyrolysis oil suitable for SAF production, making the feedstock route a promising second option.

Niutech’s industrial continuous waste plastic line is highly tolerant of feedstock quality: it requires no complex washing, sorting, drying or fine shredding, and directly pyrolyzes low-value waste plastics — including PP, PE, PS, ABS and nylon, single or mixed — with high efficiency and long-cycle, safe, stable continuous operation at large throughput. Niutech’s waste plastic pyrolysis solutions have been commercialized in the UK, South Korea, Denmark, Thailand, Vietnam, China and other markets, supporting multiple 10,000-tonne-scale continuous projects, including the European Waste Plastic Pyrolysis Chemical Recycling Demonstration Project, the Southeast Asian Waste Plastic Pyrolysis Chemical Recycling Demonstration Project, and China’s first large-scale continuous pyrolysis project for medical waste plastics.

Waste plastic pyrolysis oil, once an alternative energy source, is now becoming a key upstream feedstock for aviation decarbonization. “Large-scale pyrolysis projects place demanding requirements on the continuous operation capability of the equipment,” said a market executive at Niutech. “Niutech has focused on pyrolysis technology for nearly 40 years and brings mature equipment and extensive project experience. This partnership is another validation of the strength of our industrial continuous technology.”

Amid Growing Water Crisis, Chandigarh University Biotechnology Researchers Get Patent for Innovative Device to Kitchen Wastewater Reuse, Save Potable Water

CU Researchers’ Patent Two-Stage Filtering Device to Address Water Scarcity
with Recycling of Kitchen Wastewater for Gardening, Cleaning and Other Uses

CHANDIGARH, India, Aug. 29, 2026 /PRNewswire/ — At a time when 80% of water supplied to households in India is released as wastewater even as over 60 crore people in the country are facing severe water crisis due to extreme groundwater over-extraction, erratic monsoons and rapid urbanisation, a team of Chandigarh University (CU) researchers has conceived and patented an innovative wastewater filtering device designed to provide a two-stage treatment for kitchen wastewater before it enters the drainage system, while also enabling collection of the filtered water for suitable domestic uses including gardening, irrigation and outdoor-area cleaning, thus  reducing the demand for fresh potable water.

Chandigarh University researchers including Prof (Dr) Anu Kumar, Associate Professor, Department of Biotechnology, CU along with two students of Biotechnology, Bhanu Krishan and Shivani have been granted a patent for this invention titled ‘Waste Water Filtering Device’ by the Patent Office, Government of India in April 2026.

Sharing details, Prof Kumar said, “The idea for this Device came from the water scarcity experienced in Shimla in 2018. This water crisis made me think that while water is an essential and limited resource, yet much water gets wasted in household activities which don’t require potable water. According to Economic Survey 2025-26, India is among the top generators of wastewater in the world, with almost 112 billion litres of urban wastewater being generated daily but only 8% of wastewater generated was being recycled and reused. So there is a need to reuse wastewater wherever possible rather than allowing it to directly go into the drainage system as over 60 Crore people in India are experiencing high to extreme water stress in India. The device was therefore designed as a simple, affordable solution to treat commonly generated household wastewater, particularly kitchen wastewater and collect it for suitable reuse. The broader aim was to make the best possible use of available water, reduce wastage and contribute to water conservation,”.

Explaining the working of this Device, Prof Kumar said, “When wastewater get generated during washing of utensils, it enters the modified strainer, the main housing of the filtering device. From there, the wastewater passes through two successive treatment sections. The first section contains multiple polyurethane sheets coated with silica along the inner walls of the strainer. These sheets serve as the primary filtering and absorbing material and are intended to absorb oily constituents and soap micelles present in kitchen wastewater. The wastewater then passes through a second section containing activated charcoal which provides second adsorption stage for contaminants in the wastewater,”.

 “Thus, the two sections work sequentially, with the first stage primarily addressing oil- and soap-containing constituents while the activated charcoal providing further adsorption of contaminants. The filtered water is then conveyed through a tail pipe connected to the strainer and directed into an attached storage tank where the treated water is collected for further suitable non-potable domestic uses,” he added.

Prof Kumar said this treated wastewater collected in the storage tank can be used for watering household plants, lawns and other vegetation. It could also potentially be used for toilet flushing, floor and outdoor-area cleaning, washing of courtyards or other utility areas, thereby reducing the demand for potable water. The basic idea is to divert relatively less-contaminated household wastewater from the drainage system, remove major constituents such as oil, grease and soap micelles through the polyurethane and activated-charcoal stages and collect filtered water for appropriate non-drinking applications, he said.

 “The ‘Waste Water Filtering Device’ is designed specifically for wastewater generated during routine washing activities in a kitchen. It integrates filtration and water collection into a single device and uses a sequential treatment concept combining silica-coated polyurethane sheets and activated charcoal. Overall, this device offers a potential preliminary treatment and water-reuse approach for domestic settings, especially for works which don’t require potable water,” Prof Kumar added.

Congratulating Chandigarh University researchers for getting the patent for the ‘Waste Water Filtering Device’, Deepinder Singh Sandhu, Senior Managing Director, Chandigarh University said, “This achievement reflects the strong research and innovation eco-system at Chandigarh University to support research excellence and intellectual property generation for advancement of technology. Chandigarh University’s students and faculty members have filed more than 6,100 patents out of which 5800 patents have been published and 260 patents have been granted. Chandigarh University has been ranked number one as a single institution in India for filing highest number of patents. CU’s 44 faculty members featured in Stanford University–Elsevier list of the world’s top 2% scientists,”.

“The range of research activities at Chandigarh University is both wide-ranging and profound. CU scholars conduct research in practically every domain, and pursue to develop human knowledge through investigation, invention, and understanding. Chandigarh University is recognized as Scientific and Industrial Research Organization (SIRO) by the Union Ministry of Science and Technology’s Department of Scientific and Industrial Research (DSIR) for promoting and advancing the research,” he said.

Sandhu further said to further strengthen its research eco-system, Chandigarh University has dedicated an annual budget of Rs 15 Crore for research and has also 60 Research Centres and 15 Centres of Excellence. CU’s research initiatives are further strengthened by 67 projects funded by the corporate sector and government bodies with Rs 90 Crore.
