In order to ensure the stable operation of solar power generation, it is important to monitor the power generation status and detect problems as early as possible. For this purpose, the introduction of a remote monitoring system is indispensable.L-eye, a remote monitoring system and service that supports a wide range of applications from low-voltage to ultra-high-voltage, is easy to install and enables full-scale monitoring, providing strong support for the power generation business.


 ■ Basic Functions

  1. 1. Graph

    The display of the transition of the generated power can be switched according to the measurement item and content.
  2. 2. Data Display

    Data such as power generation, solar radiation, and temperature can be checked in graphs and reports.
  3. 3. Data Download

    Measurement data can be downloaded in CSV format.
  4. 4. Record List

    You can register the information necessary to run the site.This is useful for maintenance implementation records, etc.
  5. 5. System Error Log.

    The history of failures and recoveries between the measurement device and the server can be checked and downloaded in CSV format.
  6. 6. Inverter Detailed Information

    Displays the current values of voltage, current, and power of each PCS, the daily total value of generated power, and the operation status.
  7. 7. Inverter Error Log

    You can check the detailed failure occurrence and recovery history of PCS and download it in CSV format.
    It can also notify you by email if the PCS fails.
  8. 8. Flex Area
