Key features of the Sungrow SG2K-S/SG2K5-S/SG3K-S Premium String Inverter

  • High efficiency: This inverter boasts a maximum efficiency of 98.2%, which converts more solar energy into usable electricity. This translates to increased power production from your solar panels.
  • Wide MPPT voltage range: The MPPT (Maximum Power Point Tracking) is a crucial feature that ensures your inverter operates at the optimal level for your solar panels. This Sungrow inverter has a wide MPPT voltage range, allowing it to function effectively under various weather conditions and extract the most power possible from your panels.
  • Flexible design: The SG2K-S/SG2K5-S/SG3K-S Premium offers a DC/AC ratio of up to 1.4. This means you can design your solar system with more DC (direct current) panels than AC (alternating current) capacity from the inverter, potentially future-proofing your system for adding more solar panels later.
  • Lightweight and transformerless: This design makes the inverter easy to install and reduces overall system weight.
  • Wi-Fi monitoring: The inverter has built-in Wi-Fi, allowing you to monitor your solar system’s performance remotely through a smartphone app. This lets you track energy production, identify potential issues, and optimise your system’s operation.
