Which Solar-Log™ is best for me?
  1. In principle, all Solar-Log™ models (Solar-Log Base 15, 100 and 2000) are capable of reliably monitoring a PV plant. The models differ primarily in how large the plant is. The Solar-Log Base 15 can be connected up to a plant size of 15 kWp, the Solar-Log Base 100 up to 100 kWp and the Solar-Log Base 2000 is designed for a maximum of 2000 kWp Extension licences are available for certain models.

  2. 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.The selection of accessories also helps when deciding on the Solar-Log™ models..

How long does the Solar-Log Base battery last?

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.

No! Only devices that are directly accessible from the Internet (port forwarding). A user password must be set in any case!

Do I have to be afraid that my system will be damaged?

No, firstly someone must have an interest in using this open function and secondly no action is possible with a possibly existing open connection to the Internet.

Why is Solar-Log only noticing this now?

Solar-Log works with various security consultants and we react actively when security companies confront us with a finding. In our current FW development, we will focus more on security issues, as we will play a more active role in the area of grid control and energy management.

How can I solve the problem?

Quite simple - follow our suggestions and use our FW hotfix
