  • The following details are important to have when selecting the best data logger for your needs: plant size, the availability of Internet, inverter type and series.
  • Here is an overview of all Supported Components by Solar-Log™ devices:

    Supported Components

The Solar-Log is supplied with power via a 24 V power supply unit (if required via a 12 V power supply unit).


The Solar-Log has a battery-buffered Real Time Clock, or RTC for short. An internal circuit ensures that the battery supplies the RTC and that it only discharges when there is no external power supply for the Solar-Log.

The RTC and therefore the respective time will continue to run in the absence of an external power supply. This is important for recording the data with the correct time stamp after the power supply has been interrupted, as it may take some time to synchronise the system time on the Internet.

The battery has been sized so that the Solar-Log Base continues to record the system time for at least 3 years from production without an external power supply.
