Removing The Card; Loading And Saving Parameters - SMA Sunny Island 2012 Technical Description

Operating the Sunny Island

10.4.2 Removing the Card

To ensure that all log data is saved upon deactivation, write all data not yet saved from the buffer
to the MMC/SD card by using the parameter "550.03 CardFunc" with the option "ForceWrite".
Data Loss
If you remove the MMC/SD card without first activating the parameter "550.03
CardFunc", you will lose all data not yet saved since the last save process (15 minutes
max.).

10.4.3 Loading and Saving Parameters

The "550.01 ParaSto" parameter allows the storage of all the current parameter settings.
Parameters already saved can be loaded using the "550.02 ParaLod" parameter.
Saving Optimal Settings
If the system is working optimally, it is a good idea to save these settings. This is especially
useful if you try something new and then later wish to reset the inverter back to the
previous settings.
When saving the parameters you have the following options:
• Set1 (save parameter set 1)
• Set2 (save parameter set 2)
When loading the parameters you have the following options:
• Set1 (load parameter set 1)
• Set2 (load parameter set 2)
• Factory (load the factory settings (reset))
Overwrite protection
The write protection function of SD cards (plastic sliding clip on the left side) is not
supported by the display. You should take note of this when writing data to your card.
