The archiving function in PowerProtect solar is purely a data archiving function, but does not allow
visualization or analysis of data.
Weather conditions
All weather data available for the PV system are displayed in the Weather Conditions window. Check the
boxes for the values that you want PowerProtect solar to store. You can select the following data (*
provided the relevant sensors are installed in the PV system):
• Temperature
