Important Information
⚠️ WARNING: The information in this quick guide is subject to change due to product updates or other reasons. This guide cannot replace the product labels or the safety precautions in the user manual unless otherwise specified. All descriptions in the manual are for guidance only.
01 Networking
This section describes the networking setup for the GoodWe Residential Smart Inverter Solutions.
The diagram illustrates a typical residential setup. A central Inverter is connected to a Switchboard and a Smart Meter via CT clamps. The Smart Meter is also connected to the grid. The Inverter communicates with external services via a Router using WiFi or LAN. A Battery System is connected to the Inverter. Users can monitor and control the system via a WEB APP, SEMS Portal, or the SolarGo mobile application, accessed through WiFi or LAN. A Smart Dongle is shown for communication.
Communication Modules
- WiFi/LAN Kit-20
- Wi-Fi Kit
- Ezlink3000
Description: Use WiFi/LAN Kit-20 or Wi-Fi kit for a single inverter. Upgrade the inverter firmware before replacing the Wi-Fi kit with a WiFi/LAN Kit-20 dongle. In parallel scenarios, the EzLink 3000 must be connected to the master inverter only; do not connect any communication module to slave inverters. The firmware version of EzLink should be 04 or above.
02 Power On/Off
This section details the power on/off procedures for single inverter and parallel systems.
Single Inverter Power On/Off

05 Equipment Commissioning
This section guides users through the commissioning process using the SolarGo app and SEMS Portal.
Prerequisites: For parallel scenarios, the SolarGo app version should be 5.3.0 or above. Follow prompts to connect the device.
Quick Settings
Navigate to Home > Settings > Quick Settings to complete the setup. The installer password is 'goodwe2010'.
Setting the Safety Code
Users can set the Safety Code and export it. Options for regions like Europe, Oceania, America, Asia, Africa, and Others are available, with specific country examples like Cyprus, Czech, Denmark, Estonia, Finland, France, Germany, Greece.
Setting Inverter Quantity (Only For Parallel Connections)
In parallel systems, specify the 'Number Of Inverters'. The diagram shows options for 2 inverters, with fields for Total Number, Total Online, and Total Abnormal.
Setting the Working Mode
Users can configure various working modes:
- Peakshaving: Reduces peak power demand by using battery discharge.
- Self-use Mode: Prioritizes solar power for self-consumption, charging batteries with excess, and using batteries at night. Aims to improve solar self-use rate.
- Back-up Mode: Provides power during grid outages, switching to off-grid operation. Switches back to grid-connected when the grid is restored.
- Economic Mode: Sets time periods for buying and selling electricity based on grid price differences.
- Smart Charging Mode: Allows PV energy exceeding grid connection limits to charge batteries, minimizing PV energy waste.
Key Parameters: Depth Of Discharge (On-Grid/Off-Grid), Reserved SOC for Peakshaving, Charging From Grid, Backup SOC, PV Charge/Export priority, Peak Limiting Power, Switch To Charge settings.
Setting the BAT Connect Mode
Users select the battery connection mode:
- Stand-alone Connect
- Parallel Connect
- Only BAT1 Connect
- Only BAT2 Connect
- No Battery
Users then select the Battery Model from a list including Lynx Home F Series G2, Lynx Home F Series G2*N, Lynx Home D Series, Lynx C Outdoor*2, and SECU-S. If a model is not found, ensure mobile network is active and restart the app.
Configuring the Network
Method I (Recommended): SolarGo App
Navigate to Home > Settings > Communication Setting > Network Settings to configure LAN or WLAN parameters. Options include DHCP or manual IP address, Subnet Mask, Gateway address, and DNS server.
Method II: SEMS Portal App
Follow prompts to configure the network.
Setting the Advanced Parameters
Navigate to Home > Settings > Advanced Settings to configure functions like DRED/Remote Shutdown/RCR or Three-phase Unbalanced Output.
- DRED/Remote Shutdown/RCR: Enable this function and check cable connections. Refer to the manual and local regulations for details.
- Three-phase Unbalanced Output: Enables output power distribution per phase according to load, aiming for zero power trading per phase. Requires device restart after configuration. Recommended for utility grids with phase-separate billing.
Setting the Power Limit Function
Users can set the 'Power Limit' (Export Power) and 'External CT Ratio'. The CT ratio is used for smart meters like GM330/GM3000C. For GM3000, the CT is included and cannot be replaced. The CT ratio is entered as the primary side current divided by the secondary side current (e.g., 3000A:5A = 600). The secondary side current must be 5A.
Creating a Power Plant
Power plants and equipment can be created and added via the SEMS Portal app. Users enter plant information including classification (e.g., Residential), capacity (kW), module amount, and optionally scan QR codes or enter serial numbers to add equipment like Inverters, Micro Inverters, Data Loggers, or EV Chargers.
