10 Reasons for investing in a Solar-Log™ monitoring system
  • The best price/performance ratio for topnotch monitoring.
  • Maximize your revenue goals; Solar-Log™ sends immediate notification by e-mail or text message in case of any malfunction or reduced performance.
  • Gain independence over rising energy costs by using the self-consumption performance feature.
  • Easy-to-use display directly on the device as well as online access for remote operation.
  • Network integration is easy and does not require software installation.
  • The Solar-Log™ monitoring system provides protection on your ROI and offers the bank security it needs.
  • Increased property values due to having a PV plant installed with self-consumption power management.
  • Convenience and certainty when used with a service contract from a monitoring specialist who will take care of things.
  • Demonstrates your active concern for environmental protection.
  • Solar-Log™ devices are made in Germany, to the highest quality standards, by the world’s market leader.
Which Solar-Log™ is best for me?
  • In principle all three Solar-Log™ models are able to monitor a PV plant completely and using modern technology via internet. The Solar-Log™ that is the best "match" depends on the plant size, availability of PC/internet and costs. The selection of accessories also helps decide which Solar-Log™ to select.

  • 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.

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.
