No SMA Grid Guard rights
You do not have
SMA Grid Guard rights even
though the SMA Grid Guard
symbol is displayed. • The inverters have not automatically reset the
SMA Grid Guard mode after ten hours. The SMA Grid Guard
rights have expired but the SMA Grid Guard symbol is still
being displayed in error.
–
Enter your personal SMA Grid Guard code
(see Section 8.5 "SMA Grid Guard", page 47).
SMA Grid Guard mode
The symbol for SMA Grid Guard
mode is no longer displayed. • If an installer has logged into Sunny Explorer in
SMA Grid Guard mode, the inverters automatically reset
the SMA Grid Guard mode after ten hours to avoid
unauthorized access. Tip: You can also exit the
SMA Grid Guard mode by closing Sunny Explorer.
Changed parameters
adopted for only one device
class • Each device class has its own interface for processing and
storing settings. Sunny Explorer only stores changes for the
device class that is assigned to the particular interface.
Changes to other device classes that are still open for
processing will not be saved.
– First save the changes made to one device class before
processing another device class.
Entering parameters in a
smaller unit • Sunny Explorer saves entered values in the unit specified
next to the input field.
– If you wish to enter values in a smaller or larger unit, you
must convert the value to the specified unit.
Sunny Explorer will automatically adjust the unit.
Example: If you want to change a parameter from
20 MWh to 900 kWh, you must enter 0.9.
Sunny Explorer automatically adjusts the entered unit
and saves the parameter as 900 kWh.
Parameters cannot be
edited • You do not possess the necessary rights for changing the
parameter.
– Change the user group.
• Your inverter is retrofitted with an SMA Bluetooth
Piggy-Back with software version older than 02.00.00.R.
Parameter configuration and the graphic display of monthly
and yearly energy values is not supported.
–
Update the Bluetooth Piggy-Back (see Section 6.10
"Updating Devices", page 40).
