High Frequency Analysis
High Frequency data analysis reveals hidden and avoidable stresses on plant components
New High Frequency network analysis measures currents, voltages, and resonances up to 150 kHz
When components of a PV system fail, it could be due to harmonic distortions in the electrical network. These can have a major impact on the connected equipment by restricting functions, which greatly accelerates the wearing and aging processes of the components. This results in recurring repair costs due to failures and defects, although the exact causes often remain unclear.
High transparency of network topography
Thanks to a high sampling rate, our analysis determines impedances, even in the high-frequency range of up to 150 kHz. In contrast to common standard measurements, this opens up completely new and much more detailed insights into the nature and quality of the network and the resulting challenges for the plant.
Derive and implement measures for trouble-free, long-term plant operation
The knowledge gained from the measurements we take can be used to derive indications of defective components, which can then be replaced in the next step and designed according to the existing grid conditions. In the case of new plants, for example, recommendations for action can be derived and implemented for the filter design of inverters before major damage occurs. Furthermore, it is possible to find out whether sources of interference outside the PV system have a negative influence on the operation of the system.

When does a high frequency analysis makes sense?
You want to determine the cause of grid disturbances
A high frequency analysis, also known as power quality analysis, is a valuable tool for identifying the root cause of power disruptions in electrical systems. It provides detailed insight into the quality of the power being supplied to a system, enabling you to locate network-related sources of downtime that may have gone undetected previously. Our experienced technicians use state-of-the-art equipment to perform high frequency analyses, providing you with comprehensive reports and recommendations for improving the reliability and efficiency of your electrical system.
To save on repair costs for wear and tear and defects of PV plant components
Our team of experts can carry out a thorough analysis of your plant components and identify the root causes of recurring failures and overloading. This will enable you to take appropriate corrective and preventative measures to minimize repair costs and yield losses. Our solutions are tailored to your specific needs and requirements to ensure that you get the most out of your PV system.
To check the current status of the electrical installation of the plant you have commissioned
Our measurement techniques and analysis can detect potential sources of interference such as radio or mobile phone masts, which can significantly reduce the efficiency of your PV system. By identifying these sources of interference, we can help you to take effective measures to mitigate the negative impact and increase the overall performance of your PV system.
You are planning to sell your plant and want to enrich the offer with an upfront assessment
A high frequency analysis is an effective tool to determine the technical status of a solar power plant. With its detailed insights into the power quality and performance of the plant, you can present a comprehensive and objective evaluation to potential buyers. This can increase the value of your solar power plant and help you achieve a better purchase price. Our team of experts can conduct a thorough analysis and provide you with a detailed report that you can use to build trust and ensure a successful transaction.
You need to do a power quality check of your system to fulfil normative requirements
Additionally, we provide recommendations for any necessary repairs or upgrades, as well as advice on optimizing plant performance. Our high-frequency analysis is conducted by experienced and certified professionals using state-of-the-art measurement equipment and techniques, ensuring accurate and reliable results. This analysis can provide valuable information for both plant owners and potential buyers, helping to ensure the long-term profitability and success of the solar power plant.
You would like to gain insight into the quality of your electrical network and the resulting challenges it poses for your PV plant
The high sampling rate used in our analysis enables us to provide you with detailed information about the behavior of your plant, even in the high-frequency range of up to 150 kHz. This allows us to identify and evaluate any disturbances, harmonic distortion, or resonances that may occur in your system, and provide recommendations for reducing these effects. With this detailed analysis, we can help you optimize the performance of your solar power plant and extend its lifespan.

Why is our high frequency analysis so unique?
An innovation in industry, exclusive at greentech
Developed for you by a strong and experienced team
Together with the engineers and grid specialists from morEnergy , we want to take the issue of power quality for photovoltaic systems to the next level. This is because we believe that a review of the normatively prescribed frequency range of up to 9 kHz will no longer be sufficient to ensure good power quality for the system and the grid in the future. The reasons for this lie in the expansion of the decentralised power supply through renewable energies and the increase in the high frequency levels of pulsing system components.
Detection of problems that would otherwise not be possible with standard analyses
