How to Access Your Sungrow System on iSolarCloud
Sungrow's iSolarCloud platform lets homeowners monitor compatible solar and battery systems through a mobile app or web browser. Follow these steps to get access to your system and check its performance. Visit the official Sungrow iSolarCloud page for platform information.
Access your system through Sungrow iSolarCloud rather than an unrelated third-party monitoring app.
Your installer may already have created the plant and assigned monitoring access.
Live monitoring depends on the system's compatible communication equipment and internet connection.
Follow These 7 Steps
Already have a Sungrow system installed? Start by checking whether your installer has provided account access.
Install iSolarCloud
Download the current Sungrow iSolarCloud app using the official app-store listing, or access the platform through a web browser.
Create or Obtain Your Account
If you do not have an account, follow the registration process and select the appropriate user type, such as End User, where available.
Registration may require details such as:
- Email address and verification code
- Password and country or region
- Server selection and time zone
Select the Correct Server
When signing in, use the same server associated with your registered account and plant. Selecting a different server can prevent the expected system from appearing.
If you cannot find your plant, confirm the account email and server with your installer before attempting to recreate the plant.
Ask Your Installer to Share Plant Access
For an existing installation, contact the original installer or retailer. They can help identify the existing plant and guide you through the appropriate access or ownership permissions.
Keep your own login details secure. You generally should not need to use an installer's personal account to monitor your system.
See the Sungrow support portal for product documentation and support resources.
Add or Link the System
Plant setup involves associating the correct system and compatible devices with the plant record. Sungrow's documented workflow includes:
- Complete plant information
- Add the relevant devices
- Configure the electricity tariff, where applicable
Australian plant registration may request details such as the National Metering Identifier (NMI), where applicable. Your installer or electricity retailer can help confirm the correct information.
Connect the Communication Device
Your inverter needs a compatible communication setup to send system data to iSolarCloud. The exact equipment depends on the inverter and installation.
Some systems use a device such as Sungrow WiNet-S2, which supports WLAN or Ethernet connectivity.
Check Your iSolarCloud Dashboard
Once your plant is correctly linked and communicating, the dashboard may show the following information, depending on your system, equipment and configuration:
Sungrow Battery Troubleshooting
Experiencing an issue with your battery? Follow these practical diagnostic steps to identify common problems before contacting your installer.
Before Troubleshooting
Do not open the battery enclosure, remove covers, disconnect battery cables, or attempt electrical repairs yourself. Battery systems contain high-voltage equipment. For electrical faults or suspected hardware problems, contact your installer or a qualified technician immediately.
If your battery isn't charging, check the following:
- Is the solar system producing power? If there is little/no solar generation, the battery may not have enough available solar energy to charge.
- Check the battery state of charge (SOC). Look at the battery SOC in iSolarCloud.
- Check the operating mode. Battery settings or energy-management settings can affect when charging occurs.
- Check for an alarm. Look under the fault/event section of iSolarCloud.
- Has the battery reached its programmed charge limit? If the battery is already at its target SOC, it may not continue charging.
If your battery is full but isn't powering your home, verify:
- Battery SOC (State of Charge)
- Current operating mode
- Discharge settings
- Backup reserve setting
- Grid conditions
- Active alarms
- Whether the home is currently consuming enough power to require battery discharge
If you cannot see your system in the app, check the following:
- Check your internet connection. The communication device needs network access to send data to iSolarCloud.
- Check iSolarCloud. Look at whether the plant is completely offline or whether only particular devices have stopped reporting.
- Check the communication device. If your system uses WiNet-S2, Sungrow specifies WLAN/Ethernet communication and provides configuration resources for it.
If an alarm appears, gather the following information before calling your installer:
- Take a screenshot of the alarm message
- Note the error code
- Note the time/date it occurred
- Note the battery SOC at the time
- Note the inverter status
Battery performance can naturally vary due to several factors. Before assuming the battery is faulty, consider:
- Weather conditions
- Household consumption changes
- Seasonal solar generation
- Battery SOC (State of Charge)
- Operating settings
- Grid conditions
- Battery temperature
- System configuration
When Should You Stop Troubleshooting?
Contact your installer immediately if you experience any of the following:
- A fault repeatedly returns
- Battery remains offline
- Battery refuses to charge/discharge
- System shuts down unexpectedly
- You see a persistent battery alarm
- You suspect physical damage
- Water has entered the equipment area
- There is an unusual smell, smoke, or heat
