  • Lithium battery (TSP 4.8 kWh)
  • Internet connection


  • Dashboard with system overview, weather data, power graphs for solar, load and utility consumption, battery SoC and other summaries
  • Detailed inverter data
  • Detailed battery data
  • Alarm data
  • Set settings remotely on 4kW/5kW The Sun Pays inverters and 5.5kW The Sun Pays inverter with USB cable (Growatt & Sacolar settings coming soon!)
  • The Sun Pays lithium battery communication for 4kW/5kW TSP inverters
  • Command line interface when used in headless mode

Installation Instructions:

  1. Extract the .tar file to your Desktop or your preferred destination. The tar file can be extracted by right-clicking the .tar file and selecting "extract here".
