GoodWe ET PLUS+ Series Hybrid Inverters

The new ET PLUS+ series from GoodWe features three-phase, high-voltage hybrid inverters designed for efficient energy storage. They provide increased energy independence and maximize self-consumption of generated energy through intelligent load management and enhanced charging and discharging capabilities. These inverters, available in power ratings from 5 kW to 10 kW, are an advanced solution for modern photovoltaic systems.

Key Features of GoodWe ET PLUS+ Series Hybrid Inverters:

  • Intelligent load management, including an integrated interface for controlling the operation of devices such as heat pumps and electric vehicle chargers.
  • Capability to oversize the DC side of the photovoltaic installation by up to 150%, maximizing energy production.
  • Asymmetric energy delivery across individual phases and an integrated backup power function with rapid switching in UPS mode.
  • Quiet, fanless design (noise emission below 30 dB) ensuring user comfort with a high maximum efficiency reaching 98.2%.
  • A wide power range from 5 kW to 10 kW (models GW5K-ET, GW6.5K-ET, GW8K-ET, GW10K-ET) equipped with two MPPT trackers for optimal energy yield.
  • Compatibility with high-voltage lithium-ion batteries (voltage range 180-600V) and self-adapting capabilities to battery management systems (BMS).

Who is it a good choice for?

Inverters from the ET PLUS+ series are an excellent choice for homeowners and small businesses looking to maximize the self-consumption of energy produced by their photovoltaic systems and enhance their energy independence. With advanced features such as intelligent load management, the ability to work with energy storage, reliable UPS-standard backup power, and silent operation, this series perfectly meets the needs of users seeking modern, efficient, and reliable energy management solutions.

Notes:

  • *¹: For 1000V installations, the maximum operating voltage is 950V. As a safety measure, a warning will appear if the PV string voltage exceeds 600V.
  • *²: In accordance with local grid regulations.
  • *³: Achievable only with sufficient battery power and power from the PV string.
  • *⁴: CAN communication is configured by default. To use RS485 communication, the appropriate communication cable must be changed.
  • *⁵: Without active backup output.
  • *⁶: For Belgium, the maximum apparent output power (VA): GW5K-ET is 5000; GW6.5K-ET is 6500; GW8K-ET is 8000; GW10K-ET is 10000.
  • *⁷: When the battery is not connected, the inverter starts working only when the PV string voltage is higher than 400V.
  • Current certificates are available on the GoodWe website.
