Access to Sungrow iSolarCloud is provided via a personal user account that is used in both the web portal and the iSolarCloud app. In practice, login problems occur regularly, for example when access fails or systems are not displayed after login. This article explains common causes and provides structured solutions.
For a general overview, see Sungrow iSolarCloud: Features, Login & Data Overview.
How does Sungrow iSolarCloud login work?
Login is based on a central user account that is created during system setup or configured by the installer.
Access is possible via:
- the iSolarCloud web portal in a browser
- the iSolarCloud app on smartphone or tablet
In most cases, the same login credentials are used for both. Differences mainly result from user roles and permissions.
User roles and access rights
The iSolarCloud system distinguishes between different roles, which are often the cause of login or access issues.
System owner
- access to own system
- view of yields and energy flows
- no advanced configuration permissions
Installer or service partner
- access to multiple systems
- extended diagnostic features
- management of technical settings
If the system is not correctly assigned to the account, the dashboard may remain empty despite a successful login.
Common Sungrow iSolarCloud login issues
Login not working
If login fails, the cause is often incorrect credentials. Typos or outdated saved passwords are common reasons.
Re-entering the credentials manually or resetting the password usually resolves the issue.
Forgotten password
A new password can be requested via the reset function. A correctly stored email address is required.
The spam folder should also be checked.
Login successful but no system visible
A common case is a successful login without any system displayed.
Possible causes:
- system not assigned to the user account
- setup not fully completed
- wrong user account used
In these cases, the installer should be contacted.
Differences between app and web portal
App and web portal use the same data. Differences are usually caused by:
- different update intervals
- cache issues
- outdated app version
Restarting the app or clearing the browser cache can help.
Error message during login
Generic error messages may indicate incorrect credentials, temporary server issues or maintenance. Trying again later is recommended.

What to do if login problems persist?
If login is not possible over a longer period, the following steps are recommended:

In many cases, the issue is related to account assignment rather than a technical defect.
