To register a system with Speedwire/Webconnect or with a Sunny Home Manager in Sunny Portal, you must enter a pv system password. Important: This is the password for the "Installer" user group that was
If you have forgotten the password for the inverter, you can unlock the inverter with a personal unlocking key (PUK). For each inverter, one PUK is available for each user group (user and installer). You can request the PUK at our SMA Service Line. With the PUK you can unlock the inverter via Sunny Explorer and then assign a new password.
This new password must therefore be used for establishing a direct connection to the inverter. If no SMA data logger has been installed in the system or no Webconnect data communication with Sunny Portal is used, the system password must be assigned either with the Sunny Explorer software or via the inverter user interface.
The new pv system password created in Sunny Portal has not been applied to the inverters. This can happen, for example, if the devices cannot be accessed or are not feeding during registration.
When you open the inverter user interface, you are prompted to enter the password for the user group “User.” Select the language and enter the password for the user group “User” twice. Compliance with the new password rules is checked (five green check marks). Press Save. You are then prompted to enter the password for the user group “Installer.”
Proper system communication is possible only if all the system inverters have been assigned the same system password. For systems with Webconnect or Sunny Home Manager, you can quickly assign the new system password in one step for all devices in the system via Sunny Portal.
If you notice that you cannot access the inverters with your current password, or no data appears in Sunny Portal, please try again with the “old” Installer password. Your installation company changed the default system password 1111 to a new password that you do not know.
