Goodwe ESA 1+3 phases

1. Goodwe ESA Inverter setup

1.1. Single-Phase Setup (EHA-G20 inverter)

  1. In the installer portal, navigate to the battery configuration.

  2. Select the battery type matching your module:

    • GoodWe ESA GW5.1-BAT-D Single Phase — for GW5.1-BAT-D-G20 and GW5.1-BAT-D-G21 modules

    • GoodWe ESA GW8.3-BAT-D Single Phase — for GW8.3-BAT-D-G20 and GW8.3-BAT-D-G21 modules

  3. Set Battery Pack Count to the total number of battery modules installed.

  4. All other fields are pre-configured.


1.2. Three-Phase Setup (ETA-G20 inverter)

  1. In the installer portal, navigate to the battery configuration.

  2. Select the battery type matching your module:

    • GoodWe ESA GW5.1-BAT-D Three Phase — for GW5.1-BAT-D-G20 and GW5.1-BAT-D-G21 modules

    • GoodWe ESA GW8.3-BAT-D Three Phase — for GW8.3-BAT-D-G20 and GW8.3-BAT-D-G21 modules

    • GoodWe ESA GW6.0-BAT-D-G20 Three Phase — for GW6.0-BAT-D-G20 modules

    • GoodWe ESA GW9.0-BAT-D-G20 Three Phase — for GW9.0-BAT-D-G20 modules

  3. Set Battery Pack Count to the total number of battery modules installed.

  4. All other fields are pre-configured.


2. GoodWe ESA Battery Modules

The GoodWe ESA battery modules (GW5.1-BAT-D-G20, GW8.3-BAT-D-G20) contain an internal DC-DC converter. Because of this, using a standard battery configuration will overestimate the available power. Follow the steps below to configure the battery correctly.


2.1. Single-Phase Setup (EHA-G20 inverter)

  • Select "Unsupported Battery"

  • Battery Pack Count: total number of battery modules installed

  • Cells Per Battery Pack: 1

  • Cell Nominal Voltage: 460 V

Cell Capacity and Cell Maximum Current depend on the module type:

Module

Cell Capacity (per module)

Cell Maximum Current (per module)

GW5.1-BAT-D-G20

11.1 Ah

10.9 A

GW8.3-BAT-D-G20

18.1 Ah

17.4 A

Multiply the values above by the number of modules installed.
