User's Guide of SolarGo App

1 Introduction

The SolarGo App is an application for on-grid inverters that do not have an LCD screen. It enables communication with the inverter via Wi-Fi locally on-site. Users can view running data and alarms, and perform parameter settings using the SolarGo app.

1.1 Function

The SolarGo App allows users to monitor inverter performance and configure settings for compatible on-grid inverters.

1.2 Connection Method

Requirements:

• The inverter must be powered on by DC input.
• For stable Wi-Fi communication, the distance between the cell phone and the inverter should be kept within 5 meters.
• The Wi-Fi function of the cell phone must be working normally.

Connection Options:

• Cell phone connects inverter directly: Visual distance ≤ 5m.
• Cell phone connects inverter via Wi-Fi router: This option is available if the inverter is already connected to a Wi-Fi router.

2 Install App

You can install the SolarGo app by searching for 'SolarGo' in the Google Play Store or Apple App Store, or by scanning the provided QR code.

• Search for 'SolarGo' in Google Play or Apple App Store.
• Alternatively, scan the QR code to download and install the app.
• The installed app icon will be 'SolarGo'.

2.1 Cell phone connects inverter directly

Open your phone's Settings > WLAN. Enable WLAN and find the Wi-Fi network named 'Solar-WiFi*' (where * represents the last 8 numbers of the inverter's serial number). Enter the password '12345678' to connect. Once connected, run the SolarGo app. The inverter's Wi-Fi name will appear in the device list.

Example: For an inverter with SN 8050KMTS16BW0003, the Wi-Fi name is Solar-WiFi16BW0003.

2.2 Cell phone connects inverter directly II

Alternatively, you can open the SolarGo app, tap +Connect Device, then tap Go to the Settings interface. Navigate to Settings > WLAN to connect to the inverter's Wi-Fi. After connecting, refresh the device list within the app.

3 Installer/Owner Login

3.1 Role Verification

1. Tap the inverter's Wi-Fi name in the device list to log in as 'installer' or 'owner' using the access code.
2. The default access code for inverters is '1234'.

Important Notes:

• Do not share the inverter's access code.
• Modify the access codes separately for installer and owner roles.
• Installer and owner roles have different authorities.
• Only one user can log into a single inverter at a time.

3.2 View running data

After successful role verification, the Overview screen will display. You can switch to the Parameters tab to view running data.

Example Data Displayed:

• DC voltage/current (per string)
• AC voltage, current, and frequency
• Power output (kW)
• Daily energy yield (kWh)
• Total energy yield (kWh)
• Firmware version
• Device type

3.2 Alarms of inverter

After role verification, the Overview screen is displayed. You can navigate to view inverter alarms.

• Check the system: Follow the solution guide provided for the specific alarm.
• Contact Support: If an alarm cannot be cleared, or if the inverter is not working without any alarm, contact GoodWe's service.

3.3 Settings

Access the Settings interface to configure various inverter parameters.

Key Settings Categories:

• Grid connection parameters: Includes basic settings, connection jump-off settings, safety options (e.g., VDE4110), and reactive power settings.
• System parameters: Time setting, change password.
• Operating parameters: Active power setting, observation time.
• Communication parameters: Wi-Fi network settings.
• Characteristic parameters: Frequency for derating start, power limit value, increasing slope, etc.
• Device maintenance: Firmware upgrade, DSP upgrade, ARM upgrade.

VAC Failure Explanation: This occurs when the inverter detects that the AC voltage is outside the normal range required by the safety country settings. Possible reasons include incorrect safety country settings, unstable grid voltage, undersized or excessively long AC cables, or poor AC cable connections.

Solution for VAC Failure: Verify and correct the safety country setting. If correct, use a multimeter to check AC side voltages (L-N) to ensure they are within the normal range.

3.4 Upgrade firmware of inverter

Follow these steps to upgrade the inverter's firmware:

1. Navigate to the Settings page and tap Firmware Upgrade.
2. Tap Select and choose the firmware file (e.g., SDT_28377(1)(1).bin).
3. Tap Upgrade.

Warning: Contact GoodWe service for firmware files and instructions. Incorrect procedures may cause inverter malfunction.

3.5 Connect inverter to Wi-Fi network

To connect the inverter to a Wi-Fi network:

1. Navigate to Settings > Communication > Wi-Fi Network.
2. Enable 'Network Connection'.
3. Select the desired Wi-Fi network name (SSID) and encryption mode.
4. Enter the Wi-Fi password.
5. Tap Set to complete the configuration.

Note: For advanced Wi-Fi configuration features, download the SEMS Portal App.
