SMA Solar Technology AG Archiving Data on a SD Card
11.2 Removing the SC Card
To ensure that all log data is saved upon deactivation, write all data not yet saved from the buffer to
the SD card by using the parameter "550.03 CardFunc" with the option "ForcedWrite".
Data loss
If you remove the SD card without first activating the parameter "550.03 CardFunc", you
lose up to a maximum of 15 minutes of data.
11.3 Saving and Loading Parameters
Using the "510.02 ParaSto" parameter, you can save the current parameter settings and using the
"510.02 ParaLod" parameter, you can load the saved parameters.
Save settings
If the system is working optimally, it is a good idea to save these settings. This is especially
useful if you try out new settings and then 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))
SD card write protection
The write protection function of SD cards (plastic sliding clip on the left side) is not
supported by the Sunny Island. You should take note of this when writing data to your card.
11.4 Writing Log Data
Using the "#550.04 DatLogEna" parameter, you can activate the function for writing log data to your
SD card (activated by default).
If the Sunny Island is writing data to the SD card,
removing the card is prohibited and the following
message appears on the display:
