Cause and solution
• For inverters with SMA Bluetooth piggy-back, the padlock symbol is
displayed when the inverter switches off at night. Since the Sunny
Beam cannot establish a connection to this inverter, it interprets this
as an incorrectly entered password.
– As soon as the inverter is switched on in the morning, the padlock
will disappear.
• Due to the extensive time management in your PV system, the first
attempt to change the time settings may not be successful, if, for
example, time has already been set using Sunny Explorer.
– Check the time settings after commissioning and correct them, if
required.
