GoodWe ET Series (15–30 kW)
The three-phase hybrid inverters from GoodWe’s 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 GoodWe ET Series (15–30 kW):
- High backup power capacity: Ensures continuity of operation for homes or businesses in case of grid outage with fast UPS switching (<10 ms).
- Wide range of power and configurations: Available in versions from 15 kW to 30 kW with 3 independent MPPT trackers, facilitating the design of 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 arc-fault protection (AFCI).
Who is this a good choice for?
The GoodWe ET inverter series (15–30 kW) is an ideal solution for owners of large photovoltaic installations in residential buildings with high energy demand as well as 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 critical.
