Photovoltaic plants represent a considerable investment. In order to secure the investment, the yields of the plant must be ensured as the investment calculation is usually based on a yield expectation. In order to secure the yield of a plant, a constant control is needed. Modern monitoring systems help here since occurring errors are immediately detected and the predicted electricity yields are secured for the operator of the photovoltaic system.

The influences on the yield of a plant can be manifold and have a different impact on the yield. In various studies* the uncertainties and influences on the yield of the plant are examined. Here, the following aspects and their weighted influence on the yield can be summarized.
The interaction of a large number of components and materials in a photovoltaic system results in a large number of theoretical error sources. The error sources themselves in turn, can show different error cases/ causes, which may have a weighted influence on the yield of the system. Here you can see a simplified example of the TOP-TEN error causes in the area of photovoltaic modules and inverters, as well as their influence on the yield in the form of a prioritized cost number*.

The Solar-Log™ device monitors the photovoltaic system and detects faults, such as the failure of an inverter, before they become a permanent problem. For a complete overview, the status and error codes of the individual inverter manufacturers are permanently recorded and saved in the event log. The Enerest ToGo App displays the deviations directly.
In order to recognise whether the photovoltaic system is working trouble-free and efficiently, the power of the inverters is compared with each other. The Solar-Log™ works with the kWp power, the normalised power of the inverters, to compare inverters of different sizes. With multi-tracker inverters, the Solar-Log™ can detect deviations down to MPP tracker level.
With the new online portal Solar-Log WEB Enerest™ 4, Solar-Log™ scores once again! One platform - All loggers! This omni-compatibility creates a standard for online monitoring. The know-how gained from more than ten successful years in the solar industry has resulted in an increasingly powerful online portal that makes the installer's daily work so much easier. Little by little, more and more loggers are being integrated. Currently, devices from meteocontrol and Huawei are compatible.
How to Fix "Loading Data Failed: Check the Configuration File" in TecDoc
TecDoc Desktop or DVD versions.
Sometimes TecDoc relies on a system variable called TDX_PATH or similar.
If you are using the TecDoc API (e.g., via RapidAPI or a custom PHP catalog like ronhartman/tecdoc-autoparts-catalog ), the error is likely in your environment settings: Missing .env File : Ensure your file exists and contains a valid RAPIDAPI_KEY PHP Memory Limit : Large data loads can crash if your memory_limit is too low. Try increasing it to Stack Overflow 🚀 Re-Installation & Updates If the configuration is correct but the error persists: Deactivate Security
If you are still unable to resolve the issue, it may be necessary to contact your TecDoc data supplier for a fresh data set. loading data failed check the configuration file tecdoc work

Our free app is available for download for Apple and Android devices, offering you functions as a professional and monitorer. In addition, the app can also be used by your customers. It provides time-saving support for use on the construction site, yet also for tracking errors for your PV systems. The app informs you when Solar-Log WEB Enerest™ 4 has detected new errors. On the go, you decide whether errors should be converted to tasks, or archived.
Self-consumption at a glance:
Your customers can use the app to overview all production and consumption values, allowing you to focus on monitoring and service. Weekly yield reports can be sent through the app with a push notification. This can be set individually per user.
