The Solar-Log 1000 and 2000 have an alarm contact which is triggered if the connection is broken.
This function can be used for various applications:

For wiring to the mounting frame or to the modules, use a thin weather-resistant cable that breaks
when strained. The maximum cable length is around 500 meters.

Connection to an uninterruptible power supply (UPS).
If the connection is broken, the Solar-Log™ can carry out the following actions:

Produce an audible signal
The notification actions can be set on the Solar-Log 2000 in the section Configuration | Notifications |
