About

SungrowEyeLight

Monitor your Sungrow solar system in real-time without an internet connection. Access data directly from the system's register, or over the internet if configured. Primarily designed for SH10RT models but compatible with most Sungrow systems.

Highlights
  • Real-time monitoring
  • Direct register data retrieval
  • Offline functionality
  • Internet data retrieval
  • Compatibility with Sungrow systems

SungrowEyeLight 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.

Verdict

The call

The clearest difference is ads: SolarMark at none against SungrowEyeLight's shown. SolarMark also leads on monetization model (free vs ad-supported) and iOS requirement (15.1 vs 18.0). SungrowEyeLight's advantage is update cadence (every 4 days vs monthly). On price, review sentiment, in-app purchases and device support there is nothing between them.
