GoodWe ET Series (15–30 kW)

The three-phase hybrid GoodWe inverters of the ET series are designed for demanding, high-power rooftop photovoltaic installations. These devices provide high efficiency, energy independence and advanced energy management thanks to the peak-shaving feature. The series offers reliable backup power with standard UPS switching in under 10 ms and the ability to work with high-voltage energy storage systems, including GoodWe Lynx Home F models.

Key features of the GoodWe ET Series (15–30 kW):

  • High backup power capacity: Ensures continuity of operation for a household or business in case of grid outage with fast UPS switching (<10 ms).
  • Wide power and configuration range: Available in versions from 15 kW to 30 kW with 3 independent MPPT units, making it easier to design large systems.
  • Peak-shaving: Intelligent energy management reduces operating costs and optimizes self-consumption.
  • High efficiency: Maximum inverter efficiency of up to 98.0% ensures effective conversion of solar energy.
  • Safety and durability: IP66 protection rating, integrated comprehensive protections, and optional AFCI arc-fault protection.

Who is this a good choice for?

The GoodWe ET inverter series with power from 15–30 kW is an ideal solution for owners of large photovoltaic installations in residential buildings with high energy demand and in commercial facilities. The device is suitable wherever reliable backup power, maximized self-consumption and flexible cooperation with three-phase high-voltage energy storage systems are crucial.
