Key features of the GoodWe ET Series (2 MPPT)

  • High efficiency: The ET series boasts a maximum efficiency of around 98.2%, This means it converts a high percentage of direct current (DC) power from your solar panels into usable alternating current (AC) power for your home, maximising energy production from your solar system.
  • Two MPPTs: A Maximum Power Point Tracker (MPPT) tracks the optimal output from a group of solar panels, ensuring you get the most power even if some panels are experiencing shading or have different orientations. Two MPPTs allow roof design flexibility, handling situations where panels might not be perfectly aligned.
  • Three-phase output: This makes the ET series suitable for larger homes or those with three-phase power connections, efficiently distributing solar power throughout your house.
  • High voltage design: The inverter can handle higher DC input voltage from your solar panels, reducing power losses over longer cable runs. This can be beneficial for installations where the inverter needs to be located away from the panels.
  • Battery compatibility (optional): The ET series can be paired with compatible batteries for solar energy storage, allowing you to increase self-consumption and maximise savings on your electricity bills.
  • Monitoring and user interface: The inverter offers Wi-Fi or Ethernet connectivity for remote monitoring via a smartphone app or web interface. This lets you track your system’s performance, identify issues, and optimise energy production.
