EN 62116 Grid Connected PV Anti Islanding Testing
The IEC standard EN 62116:2015, titled “Grid-connected inverters for photovoltaic (PV) systems,” specifies the requirements for grid connected inverters used in PV systems. One of its key aspects is anti-islanding protection, which ensures that a photovoltaic system does not continue to supply power if the utility network loses voltage or frequency.
Anti-islanding testing is critical because it prevents backfeeding into the electrical grid when an outage occurs, thereby protecting utility workers who may be repairing downed lines. The test verifies that the inverter disconnects from the grid within a specified time frame (typically between 0.2 to 10 seconds) if the utility voltage or frequency deviates outside of safe operating limits.
Our laboratory adheres strictly to EN 62116 and other relevant standards, such as IEC 61215 for photovoltaic module testing. We utilize state-of-the-art equipment tailored specifically for grid connected PV systems, including power analyzers, voltage/frequency simulators, and data logging systems. Our team of experienced engineers ensures that all tests are conducted under controlled conditions to simulate real-world scenarios.
The testing process involves connecting the inverter to a simulated utility network. We then apply variations in voltage and frequency to observe how quickly and accurately the inverter responds according to EN 62116 requirements. This includes monitoring the current waveform, power factor, and overall efficiency during both normal operation and fault conditions.
Our services extend beyond mere compliance; we provide detailed reports that not only confirm adherence to regulatory standards but also offer insights into potential improvements in design or manufacturing processes. By working closely with our clients from concept through final implementation, we help ensure long-term reliability and safety of their products.
In addition to standard testing procedures, we can customize protocols based on specific client needs or additional requirements stipulated by local regulations or international markets. For instance, if a particular region mandates stricter anti-islanding performance criteria, our team will adjust the test parameters accordingly without compromising accuracy or integrity.
With over [X] years of experience in renewable energy electronics testing, we have successfully completed numerous projects related to EN 62116 compliance across various industries. Our clients include leading manufacturers and suppliers who rely on us for reliable, consistent results that meet the highest industry standards.
Scope and Methodology
The scope of our EN 62116 Grid Connected PV Anti Islanding Testing includes a comprehensive examination of grid connected inverters used in photovoltaic systems. This testing focuses on ensuring that these devices comply with the specified limits regarding anti-islanding behavior as outlined by IEC standard EN 62116:2015.
Our methodology involves setting up a controlled environment where we simulate various fault conditions such as voltage dips, frequency variations, and complete power outages. Using advanced instrumentation like power analyzers and voltage/frequency simulators, we carefully monitor the inverter’s response to these disturbances.
A key component of our testing process is measuring the time taken for the inverter to disconnect from the grid once a fault condition is detected. According to EN 62116:2015, this disconnection must occur within 0.2 seconds up to 10 seconds depending on the severity and type of fault encountered.
We also evaluate other critical parameters during testing such as residual power levels after isolation, total harmonic distortion (THD), and reactive power compensation capabilities. These metrics are essential in assessing not only compliance with EN 62116 but also providing valuable feedback for continuous improvement purposes.
In addition to the above, we employ rigorous quality control measures throughout each stage of testing to ensure accuracy and consistency. Our state-of-the-art facilities include specialized chambers capable of replicating diverse environmental conditions which can affect inverter performance under real-world operating conditions.

Environmental and Sustainability Contributions
The importance of renewable energy cannot be overstated in today’s world, where climate change and environmental degradation are pressing global challenges. Photovoltaic (PV) systems play a crucial role in harnessing solar power to generate electricity sustainably. However, it is equally important that these systems operate safely within the confines of their intended environments.
Our EN 62116 Grid Connected PV Anti Islanding Testing contributes significantly to environmental sustainability by promoting safer and more reliable operation of PV inverters connected directly to utility grids. By ensuring that these devices comply with strict anti-islanding requirements, we help prevent potential hazards such as backfeeding into downed power lines during outages.
From an ecological perspective, reducing the risk of accidents involving utility workers contributes positively towards preserving natural ecosystems and biodiversity. It also reduces waste associated with emergency response efforts required when such incidents do occur.
On a broader scale, promoting compliance with international standards like EN 62116 helps drive innovation within the renewable energy sector. As more countries adopt stringent regulations governing grid-connected PV systems, adherence to these standards becomes increasingly important for manufacturers aiming to expand into new markets or improve existing product offerings.
In essence, our testing services support a circular economy model by encouraging efficient use of resources through sustainable practices. By ensuring that PV inverters function reliably and safely under all conditions, we contribute towards creating a healthier planet for future generations.
