Technical Description
11.2 Removing the SD Card
To ensure that all log data is saved upon deactivation, write all as-yet unsaved data from the buffer
to the SD card by using the parameter ”550.03 CardFunc” with the option ”ForcedWrite”.
11.3 Saving and Loading Parameters
You can specify and use different settings with different parameter, i.e. for winter and summer. These
sets of parameters are called set 1 and set 2. Using the ”550.01 ParaSto” parameter, you can save
the current parameter settings and using the ”550.02 ParaLod” parameter, you can load the saved
parameters.
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))
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 message shown
here is displayed.
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' data.
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.
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.
