use to log in to SunnyPortal.
SunnyPortal password requirements:
☐ The SunnyPortal password must contain at least 10 characters and no more than 50 characters. The strict

System Password
All devices connected via Speedwire with the same password form a system. For this reason, a password used for all
devices in a system is called a system password. The system-specific password protects a system's communication.
You can only access the devices in your PV system via your communication product if all devices have the same
password.
You must define the system password in SunnyPortal when you register the SunnyHomeManager system. The system
password that you defined upon registration of the SunnyHomeManager is the password of the user group Installer.
System and installer password requirements:
The system-specific system password must consist of at least 8 characters and no more than 12 characters,
including
• at least a lowercase letter
• at least an uppercase letter
• at least a digit and
• at least one of the following permitted special characters: ? _ ! -
Password for Edimax radio-controlled sockets
The same password must be used for all Edimax radio-controlled sockets in the system that require a password. If there
are different passwords for the radio-controlled sockets, the SunnyHomeManager cannot control all radio-controlled
sockets.
Make sure that the shared password is entered at the following positions:
• In the separate Edimax app for each radio-controlled socket registered there
• In the SunnyHomeManager properties (see Section11.3.7, page58)
