SungrowEye is a real-time monitor for Sungrow solar systems, retrieving all necessary data directly from the solar system’s register without requiring an internet connection. If the solar system’s register is made accessible over the home network for internet use, the data can also be retrieved in real-time over the internet directly from the register. SungrowEye was specifically developed for the SH10RT model. However, as the internal register of Sungrow solar systems, with so-called I18N values, should be compatible across different models, SungrowEye should work with all common Sungrow solar systems.
