GoodWe GW20K-ET hybrid inverter ET series


The trend towards more and more powerful PV modules influences the overall requirements of a PV system. At the forefront of development, GoodWe ET inverters efficiently meet the needs of larger residential and commercial properties with powerful backup power, peak shaving and load management for optimized autonomy and reduced energy costs. The ET series can be combined with numerous HV batteries. GoodWe's ET-plus series offers three-phase hybrid inverters for high-voltage batteries, which enable even more independence in energy supply and maximize self-consumption through intelligent control of loads and higher charging and discharging performance. The ET series has a power range of 15 kW, 20 kW, 25 kW and 30 kW. It also has a back-up function with an uninterrupted switching time.

Capable of emergency power

  • Emergency power with uninterrupted switching < 10 ms.

Highest security standards

  • Integrated surge protection type II on the DC side.
  • Protection class IP66.

Optimized energy autonomy

  • Wide battery voltage range (200 - 800V).
  • Supports dynamic active power limitation and load visualization.

Smart and efficient operation

  • Supports smart home interactions via different communication protocols.
